Tidskriftsartikel (refereegranskat)abstract
- Adrenal insufficiency (AI) is a rare disorder characterised by an impaired secretion of glucocorticoids from the adrenal glands. Treatment strategies for AI have developed over time with reduced glucocorticoid replacement doses and improved circadian exposure regimens, but whether this has resulted in better survival is unknown. The main purpose of this systematic review is to gather and synthesise available evidence on long-term mortality in patients with AI. The secondary aim is to study causes of death, with focus on cardiovascular and infectious diseases, in AI patients.Studies published from the inception of respective databases (Medline, Embase, Cochrane and Web of Science) until the end of May 2023 will be systematically synthetised. Observational studies with a reference population will be included, and their quality will be assessed using the Newcastle-Ottawa scale. Data collected will be narratively integrated and a meta-analysis will be performed to pool data from studies considered homogeneous. The systematic review will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. This will be the first systematic review assessing mortality and causes of death in AI patients. The findings of this systematic review will be of value for both patients and healthcare providers.This systematic review does not require ethical approval or informed consent because it will be based on previously published data only and does not implicate any direct contact with individual patients. The research results will be presented at scientific conferences and submitted for publication in an internationally recognised peer-reviewed scientific journal.CRD42023416253.

Growth Hormone Deficiency Is Associated with Worse Cardiac Function, Physical Performance, and Outcome in Chronic Heart Failure: Insights from the TOSCA. GHD Study
- 2017

Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 12:1

Tidskriftsartikel (refereegranskat)abstract
- Background Although mounting evidence supports the concept that growth hormone (GH) deficiency (GHD) affects cardiovascular function, no study has systematically investigated its prevalence and role in a large cohort of chronic heart failure (CHF) patients. Aim of this study is to assess the prevalence of GHD in mild-to-moderate CHF and to explore clinical and functional correlates of GHD. One-hundred thirty CHF patients underwent GH provocative test with GHRH+arginine and accordingly categorized into GH-deficiency (GHD, n = 88, age = 61.6 +/- 1.1 years, 68% men) and GH-sufficiency (GHS, n = 42, age = 63.6 +/- 1.5 years, 81% men) cohorts. Both groups received comprehensive cardiovascular examination and underwent Doppler echocardiography, cardiopulmonary exercise testing, and biochemical and hormonal assay. GHD was detected in roughly 30% of CHF patients. Compared to GHD, GHS patients showed smaller end-diastolic and end-systolic LV volumes (-28%, p=.008 and -24%, p=.015, respectively), lower LV end-systolic wall stress (-21%, p=.03), higher RV performance (+18% in RV area change, p=.03), lower estimated systolic pulmonary artery pressure (-11%, p=.04), higher peak VO2 (+20%, p=.001) and increased ventilatory efficiency (-12% in VE/VCO2 slope, p=.002). After adjusting for clinical covariates (age, gender, and tertiles of LV ejection fraction, IGF-1, peak VO2, VE/VCO2 slope, and NT-proBNP), logistic multivariate analysis showed that peak VO2 (beta = -1.92, SE = 1.67, p=.03), VE/VCO2 slope (beta = 2.23, SE = 1.20, p=.02) and NT-proBNP (beta = 2.48, SE = 1.02, p=.016), were significantly associated with GHD status. Finally, compared to GHS, GHD cohort showed higher all-cause mortality at median follow-up of 3.5 years (40% vs. 25%, p<.001, respectively), independent of age, sex, NT-proBNP, peak VO2 and LVEF. GH deficiency identifies a subgroup of CHF patients characterized by impaired functional capacity, LV remodeling and elevated NT-proBNP levels. GHD is also associated with increased all-cause mortality.

Tidskriftsartikel (refereegranskat)abstract
- AimsDue to the shortage of heart donors, increasing numbers of heart transplantation (HTx) candidates are receiving long-term mechanical circulatory support (MCS) as bridge-to-transplantation. Treatment with MCS is associated with increased formation of anti-human leukocyte antigen antibodies (allosensitization), but whether this affects post-HTx outcomes is unclear. Methods and resultsWe included all adult patients who received long-term MCS as bridge-to-transplantation and underwent subsequent HTx at our centre between 2008 and 2018. We also enrolled medically treated HTx recipients without prior MCS as controls. These controls were matched by age, sex, diagnosis, and transplantation era. Outcome parameters were compared between the two study groups. A total of 126 patients (48 +/- 15 years, 84% male) were included of whom 64 were bridged with MCS and 62 were matched controls. Pre-HTx allosensitization occurred more frequently in the MCS group than in the control group (27% vs. 11%, P = 0.03). At post-HTx year 10, the overall survival probability was 84% among patients treated with MCS and 90% among those medically managed (P = 0.32). At post-HTx year 1, freedom from treated rejections (>= ISHLT 2R) was 69% in the MCS group and 70% in the control group (P = 0.94); and freedom from any rejection was 8% and 5%, respectively (P = 0.98). There were no differences in renal function or cardiac allograft vasculopathy (grade >= 1) between groups at 1, 3, and 5 years post-HTx. ConclusionsAlthough patients treated with MCS had a higher frequency of pre-HTx allosensitization, there were no significant differences in post-HTx graft survival, biopsy-proven rejections, or renal function as compared with patients not bridged with MCS.

Pulmonary Hypertension Phenotype Can Be Identified in Heart Failure With Reduced Ejection Fraction Using Echocardiographic Assessment of Pulmonary Artery Pressure With Supportive Use of Pressure Reflection Variables
- 2023
-
Ingår i: Journal of the American Society of Echocardiography. - : Elsevier BV. - 0894-7317. ; 36:6, s. 604-614

Tidskriftsartikel (refereegranskat)abstract
- Background: Pulmonary hypertension (PH) is frequent in patients with heart failure and reduced ejection fraction (HFrEF) with 2 different phenotypes: isolated postcapillary PH (IpcPH) and, with the worst prognosis, combined pre- and postcapillary PH (CpcPH). The aims of the present echocardiography study were to investigate (1) the ability to identify PH phenotype in patients with HFrEF using the newly adopted definition of PH (mean pulmonary artery pressure >20 mm Hg) and (2) the relationship between PH phenotype and right ventricular (RV) function. Methods: One hundred twenty-four patients with HFrEF consecutively referred for heart transplant or heart failure workup were included with echocardiography and right heart catheterization within 48 hours. We estimated systolic pulmonary artery pressure (sPAPDoppler) and used a method to detect increased pulmonary vascular resistance (>3 Wood units) based on predefined thresholds of 3 pressure reflection (PRefl) variables (the acceleration time in the RV outflow tract [RVOT], the interval between peak RVOT and peak tricuspid regurgitant velocity, and the RV pressure augmentation following peak RVOT velocity). Results: Using receiver operator characteristic analysis in a derivation group (n = 62), we identified sPAPDoppler ≥35 mm Hg as a cutoff that in a test group (n = 62) increased the likelihood of PH 6.6-fold. The presence of sPAPDoppler >40 mm Hg and 2 or 3 positive PRefl variables increased the probability of CpcPH 6- to 8-fold. A 2-step approach with primarily assessment of sPAPDoppler and the supportive use of PRefl variables in patients with mild/moderate PH (sPAPDoppler 41-59 mm Hg) showed 76% observer agreement and a weighted kappa of 0.63. The steady-state (pulmonary vascular resistance) and pulsatile (compliance, elastance) vascular loading are increased in both IpcPH and CpcPH with a comparable degree of RV dysfunction. Conclusions: The PH phenotype can be identified in HFrEF using standard echocardiographic assessment of pulmonary artery pressure with supportive use of PRefl variables in patients with mild to moderate PH.

Tidskriftsartikel (refereegranskat)abstract
- Renal dysfunction in patients with heart failure (HF) has traditionally been attributed to declining cardiac output and renal hypoperfusion. However, other central haemodynamic aberrations may contribute to impaired kidney function. This study assessed the relationship between invasive central haemodynamic measurements from right-heart catheterizations and measured glomerular filtration rate (mGFR) in advanced HF.All patients referred for heart transplantation work-up in Sweden between 1988 and 2019 were identified through the Scandiatransplant organ-exchange organization database. Invasive haemodynamic variables and mGFR were retrieved retrospectively. A total of 1001 subjects (49±13years; 24% female) were eligible for the study. Analysis of covariance adjusted for age, sex, and centre revealed that higher right atrial pressure (RAP) displayed the strongest relationship with impaired GFR [β coefficient -0.59; 95% confidence interval (CI) -0.69 to -0.48; P<0.001], followed by lower mean arterial pressure (MAP) (β coefficient 0.29; 95% CI 0.14-0.37; P<0.001), and finally reduced cardiac index (β coefficient 3.51; 95% CI 2.14-4.84; P<0.003). A combination of high RAP and low MAP was associated with markedly worse mGFR than any other RAP/MAP profile, and high renal perfusion pressure (RPP, MAP minus RAP) was associated with superior renal function irrespective of the degree of cardiac output.In patients with advanced HF, high RAP contributed more to impaired GFR than low MAP. A higher RPP was more closely related to GFR than was high cardiac index.

Tidskriftsartikel (refereegranskat)abstract
- Medical treatment for cardiac amyloidosis (CA) is evolving rapidly. Heart transplantation can be a valid option when followed by transplantation of bone marrow or liver, dependent on the type and origin of the amyloid protein. Thus, accurate typing of amyloidosis has implications for treatment, prognosis, and genetic counseling. Although non-invasive diagnostic techniques can type CA, endomyocardial biopsy (EMB) may be needed in the case of equivocal imaging findings or discordant data. We aimed to define the role of mass spectrometry (MS) for diagnosis and subtyping of CA.Nineteen previously diagnosed CA cases, who underwent EMB at Sahlgrenska University Hospital (SU), Gothenburg, between the beginning 1990s and 2016, were selected. MS analysis, modified from was conducted on duplicate samples from myocardial tissue for each case included.1 Clinical features and diagnoses were used as gold standard and compared to the MS findings.Clinical diagnosis and the MS analysis agreed in 14 cases (73.7 %); in 3/19 (15.8 %) diagnosis was unclear or discordant (Fig.1). MS analysis revealed that transthyretin (TTR) amyloidosis was the most abundant amyloid protein in the samples examined (9/19; 47.3 %), whereas the AA subtype only occurred in 1 case (5.2 %). The AL κ type amyloidosis occurred in 3 cases (15.8 %), and AL λ type in six cases (31.6 %). These results strongly correlated with the clinical features in all patients. Clinical diagnosis could not be retrieved from the medical records in 2 cases (10.4 %). Additional 20 patients with clinical CA are presently under study.MS analysis of a small amount of endomyocardial tissue can be used to subtype CA with a high diagnostic validity. The method differentiated between TTR, SAA and Ig light chain amyloidosis. AL κ and AL λ identities correlated to those found in serum and urine electrophoreses. MS can therefore be of use to subtype CA for cases in which clinical findings are inconclusive. 1) Brambilla F et al. Blood. 2012 Feb 23;119(8):1844-7.

- Background Cardiac involvement can be an initial manifestation in sarcoidosis. However, little is known about the association between various clinical phenotypes of cardiac sarcoidosis (CS) and outcomes. We aimed to analyze the relation of different clinical manifestations with outcomes of CS and to investigate the relative importance of clinical features influencing overall survival. Methods and Results A retrospective cohort of 141 patients with CS enrolled at 2 Swedish university hospitals was studied. Presentation, imaging studies, and outcomes of de novo CS and previously known extracardiac sarcoidosis were compared. Survival free of primary composite outcome (ventricular arrhythmias, heart transplantation, or death) was assessed. Machine learning algorithm was used to study the relative importance of clinical features in predicting outcome. Sixty-two patients with de novo CS and 79 with previously known extracardiac sarcoidosis were included. De novo CS showed more advanced New York Heart Association class (P=0.02), higher circulating levels of NT-proBNP (N-terminal pro-B-type natriuretic peptide) (P<0.001), and troponins (P<0.001), as well as a higher prevalence of right ventricular dysfunction (P<0.001). During a median (interquartile range) follow-up of 61 (44-77) months, event-free survival was shorter in patients with de novo CS (P<0.001). The top 5 features predicting worse event-free survival in order of importance were as follows: impaired tricuspid annular plane systolic excursion, de novo CS, reduced right ventricular ejection fraction, absence of β-blockers, and lower left ventricular ejection fraction. Conclusions Patients with de novo CS displayed more severe disease and worse outcomes compared with patients with previously known extracardiac sarcoidosis. Using machine learning, right ventricular dysfunction and de novo CS stand out as strong overall predictors of impaired survival.

- Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) are rare diseases that share some similarities, but also display different clinical and histopathological features. We aimed to compare the demographics, clinical presentation, and outcome of patients diagnosed with CS or GCM.We compared the clinical data and outcome of all adult patients with CS (n=71) or GCM (n=21) diagnosed at our center between 1991 and 2020.The median (interquartile range) follow-up time for patients with CS and GCM was 33.5 [6.5-60.9] and 2.98 [0.6-40.9] months, respectively. In the entire cohort, heart failure (HF) was the most common presenting manifestation (31%), followed by ventricular arrhythmias (25%). At presentation, a left ventricular ejection fraction of<50% was found in 54% of the CS compared to 86% of the GCM patients (P=0.014), while corresponding proportions for right ventricular dysfunction were 24% and 52% (P=0.026), respectively. Advanced HF (NYHA≥IIIB) was less common in CS (31%) than in GCM (76%). CS patients displayed significantly lower circulating levels of natriuretic peptides (P<0.001) and troponins (P=0.014). Eighteen percent of patients with CS included in the survival analysis reached the composite endpoint of death or heart transplantation (HTx) compared to 68% of patients with GCM (P<0.001).GCM has a more fulminant clinical course than CS with severe biventricular failure, higher levels of circulating biomarkers and an increased need for HTx. The histopathologic diagnosis remained key determinant even after adjustment for markers of cardiac dysfunction.

Echocardiography in inflammatory heart disease: A comparison of giant cell myocarditis, cardiac sarcoidosis, and acute non-fulminant myocarditis
- 2023
-
Ingår i: IJC Heart and Vasculature. - 2352-9067. ; 46
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Giant cell myocarditis (GCM) and cardiac sarcoidosis (CS) are, in contrast to acute non-fulminant myocarditis (ANFM), rare inflammatory diseases of the myocardium with poor prognosis. Although echocardiography is the first-line diagnostic tool in these patients, their echocardiographic appearance has so far not been systematically studied. Methods: We assessed a total of 71 patients with endomyocardial biopsy-proven GCM (n = 21), and CS (n = 25), as well as magnetic resonance-verified ANFM (n = 25). All echocardiographic examinations, performed upon clinical presentation, were reanalysed according to current guidelines including a detailed assessment of right ventricular (RV) dysfunction. Results: In comparison with ANFM, patients with either GCM or CS were older (mean age (±SD) 55 ± 12 or 53 ± 8 vs 25 ± 8 years), more often of female gender (52% or 24% vs 8%), had more severe clinical symptoms and higher natriuretic peptide levels. For both GCM and CS, echocardiography revealed more frequently signs of left ventricular (LV) dysfunction in form of a reduced ejection fraction (p < 0.001), decreased cardiac index (p < 0.001) and lower global longitudinal strain (p < 0.001) in contrast to ANFM. The most prominent increase in LV end-diastolic volume index was observed in CS. In addition, RV dysfunction was more frequently found in both GCM and CS than in ANFM (p = 0.042). Conclusions: Both GCM and CS have an echocardiographic and clinical appearance that is distinct from ANFM. However, the method cannot further differentiate between the two rare entities. Consequently, echocardiography can strengthen the initial clinical suspicion of a more severe form of myocarditis, thus warranting a more rigorous clinical work-up.

- We present the case of a 47-year-old man with a history of recurrent episodes of frontal headache, fever, and chest discomfort as well as longstanding, difficult to treat arterial hypertension. Clinical work-up revealed the unexpected finding of an underlying pheochromocytoma as well as recent "silent" myocardial infarction. Our case highlights the importance of paying attention to incidental cardiac findings on somatostatin receptor positron emission tomography/computed tomography, as routinely performed in patients with clinically suspected neuroendocrine tumors. These incidental cardiac findings cannot only indicate a primary or secondary (metastatic) neuroendocrine tumor, but also areas of myocardial inflammation, as somatostatin receptors cannot only be found on the majority of neuroendocrine tumors, but also among other tissues on the surface of activated macrophages and lymphocytes. The detection of myocardial inflammation is of clinical importance and its underlying etiology should be evaluated to prompt eventual necessary treatment, as it is a potential driving force for cardiac remodeling and poor prognosis.

- Heart transplantation (HTx) for patients with "giant cell myocarditis" (GCM) or "cardiac sarcoidosis" (CS) is still controversial. However, no single center has accumulated enough experience to investigate post-HTx outcome. The primary aim of this systematic review is to identify, appraise, and synthesize existing literature investigating whether patients who have undergone HTx because of GCM or CS have worse outcomes as compared with patients transplanted because of other etiologies. A systematic and comprehensive search will be performed using PubMed, Scopus, Web of Science, EMBASE, and Google Scholar, for studies published up to December 2019. Observational and interventional population-based studies will be eligible for inclusion. The quality of observational studies will be assessed using the Newcastle-Ottawa scale, while the interventional studies will be assessed using the Cochrane Effective Practice Organization of Care tool. The collected evidence will be narratively synthesized; in addition, we will perform a meta-analysis to pool estimates from studies considered to be homogenous. Reporting of the systematic review and meta-analysis will be in accordance with the Meta-analysis of Observational Studies in Epidemiology Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines. To our knowledge, this will be the first synthesis of outcomes, including survival, acute cellular rejection, and disease recurrence, in patients with either GCM or CS treated with HTx. Reviewing the suitability of HTx in this population and highlighting areas for further research will benefit both patients and healthcare providers. Trial registration: CRD42019140574.

- Giant cell myocarditis (GCM) and cardiac sarcoidosis (CS) are rare inflammatory diseases of the myocardium with poor prognosis. Little is known about the cardiovascular magnetic resonance (CMR) appearance of GCM and the methods ability to distinguish the two rare entities from one another.We assessed a total of 40 patients with endomyocardial biopsy-proven GCM (n=14) and CS (n=26) concerning their clinical and CMR appearance in a blinded manner.Patients with GCM and CS were of similar median age (55 vs 56years), and a male predominance was observed in both groups. In GCM, median levels of troponin T (313 vs 31ng/L, p<0.001), and natriuretic peptides (6560 vs 676pg/mL, p<0.001) were higher than in CS, and the clinical outcome worse (p=0.04). On CMR imaging, the observed alterations of left and right ventricular (LV/RV) dimensions and function were similar. GCM showed multifocal LV late gadolinium enhancement (LGE) with a similar longitudinal, circumferential, and radial distribution as in CS, including suggested signature imaging biomarkers of CS like the "hook sign" (71% vs 77%, p=0.702). The median LV LGE enhanced volume was 17% and 22% in GCM and CS (p=0.150), respectively. The number of RV segments with pathologically increased T2 signal and/or LGE were most extensive in GCM.The CMR appearance of both GCM and CS is highly similar, making the differentiation between the two rare entities solely based on CMR challenging. This stands in contrast to the clinical appearance, which seems to be more severe in GCM.

- Heart transplantation (HTx) is a valid therapeutic option for end-stage heart failure secondary to cardiac sarcoidosis (CS) or giant-cell myocarditis (GCM). However, post-HTx outcomes in patients with inflammatory cardiomyopathy (ICM) have been poorly investigated. We searched PubMed, Scopus, Science Citation Index, EMBASE, and Google Scholar, screened the gray literature, and contacted experts in the field. We included studies comparing post-HTx survival, acute cellular rejection, and disease recurrence in patients with and without ICM. Data were synthesized by a random-effects meta-analysis. We screened 11,933 articles, of which 14 were considered eligible. In a pooled analysis, post-HTx survival was higher in CS than non-CS patients after 1year (risk ratio [RR] 0.88, 95% confidence interval [CI] 0.60-1.17; I2=0%) and 5years (RR 0.72, 95% CI 0.52-0.91; I2=0%), but statistically significant only after 5years. During the first-year post-HTx, the risk of acute cellular rejection was similar for patients with and without CS, but after 5years, it was lower in those with CS (RR 0.38, 95% CI 0.03-0.72; I2=0%). No difference in post-HTx survival was observed between patients with and without GCM after 1year (RR 1.16, 95% CI 0.05-2.28; I2=0%) or 5years (RR 0.98, 95% CI 0.42-1.54; I2=0%). During post-HTx follow-up, recurrence of CS and GCM occurred in 5% and 8% of patients, respectively. Post-HTx outcomes in patients with CS and GCM are comparable with cardiac recipients with other heart failure etiologies. Patients with ICM should not be disqualified from HTx.

Tidskriftsartikel (refereegranskat)abstract
- Myocarditis is a disease caused by cardiac inflammation that can progress to dilated cardiomyopathy, heart failure, and eventually death. Several etiologies, including autoimmune, drug-induced, and infectious, lead to inflammation, which causes damage to the myocardium, followed by remodeling and fibrosis. Although there has been an increasing understanding of pathophysiology, early and accurate diagnosis, and effective treatment remain challenging due to the high heterogeneity. As a result, many patients have poor prognosis, with those surviving at risk of long-term sequelae. Current diagnostic methods, including imaging and endomyocardial biopsy, are, at times, expensive, invasive, and not always performed early enough to affect disease progression. Therefore, the identification of accurate, cost-effective, and prognostically informative biomarkers is critical for screening and treatment. The review then focuses on the biomarkers currently associated with these conditions, which have been extensively studied via blood tests and imaging techniques. The information within this review was retrieved through extensive literature research conducted on major publicly accessible databases and has been collated and revised by an international panel of experts. The biomarkers discussed in the article have shown great promise in clinical research studies and provide clinicians with essential tools for early diagnosis and improved outcomes.

- Heart failure (HF) is a clinical syndrome consisting of typical symptoms and signs due to structural and/or functional abnormalities of the heart, resulting in elevated intracardiac pressures and/or inadequate cardiac output. The vascular system plays a crucial role in the development and progression of HF regardless of ejection fraction, with endothelial dysfunction (ED) as one of the principal features of HF. The main ED manifestations (i.e., impaired endothelium-dependent vasodilation, increased oxidative stress, chronic inflammation, leukocyte adhesion, and endothelial cell senescence) affect the systemic and pulmonary haemodynamic and the renal and coronary circulation. The present review is aimed to discuss the contribution of ED to HF pathophysiology-in particular, HF with preserved ejection fraction-ED role in HF patients, and the possible effects of pharmacological and non-pharmacological approaches. For this purpose, relevant data from a literature search (PubMed, Scopus, EMBASE, and Medline) were reviewed. As a result, ED, assessed via venous occlusion plethysmography or flow-mediated dilation, was shown to be independently associated with poor outcomes in HF patients (e.g., mortality, cardiovascular events, and hospitalization due to worsening HF). In addition, SGLT2 inhibitors, endothelin antagonists, endothelial nitric oxide synthase cofactors, antioxidants, and exercise training were shown to positively modulate ED in HF. Despite the need for future research to better clarify the role of the vascular endothelium in HF, ED represents an interesting and promising potential therapeutic target.

- Early detection and initiation of treatment in cardiac sarcoidosis (CS) is believed to be crucial to reduce morbidity and mortality. The diagnosis of CS is challenging, especially in isolated CS (ICS). Certain human leukocyte antigen (HLA-DRB1) alleles associate with different phenotypes of sarcoidosis. Phenotypic and genotypic characterization of patients with CS may improve our ability to identify patients being at risk for developing CS.87 patients with CS, identified at two Swedish university hospitals were included. Phenotypic characteristics were extracted from the medical records and the patients were HLA-DRB1 typed.Median age at diagnosis was 55years, 37% were women. HLA-DRB1 distribution was similar to a general sarcoidosis population. A majority of patients (51/87) had CS as the first sarcoidosis presentation. They were younger (p=0.04), more often presenting with ventricular tachycardia (VT) or atrioventricular block (AVB) grade II or III (p<0.001), had lower left ventricular ejection fraction (LVEF) (p=0.002), lower serum angiotensin converting enzyme (s-ACE) (p=0.025), and fewer extra cardiac manifestations (ECM) (p=0.02) than those presenting with CS later.Of Swedish CS patients, 59% presented with cardiac involvement as first manifestation. They had more severe cardiac symptoms than patients presenting with CS later. This phenotype disclosed less ECM and lower s-ACE thus diagnosis can be missed or delayed. We did not observe significant differences in HLA-DRB1 allele frequency between patients with CS compared to sarcoidosis in general. Awareness of CS as a primary manifestation can enable early detection and adequate intervention.

- To investigate the survival of heart transplant (HTx) recipients during different time periods in Sweden. We hypothesized that the survival for HTx recipients has improved following advancements in the management of these patients.Data was obtained through the database of the organ exchange organization Scandiatransplant. All patients who underwent HTx in Sweden between Jan 1988 and Dec 2017 were included. Patients were divided into five cohorts of six-year periods each.A total of 1137 HTx recipients were included. Main causes of transplantation were dilated cardiomyopathy (44 %) and ischemic heart disease (18 %). Retransplantation constituted a small portion of the overall total (2 %). The cohorts were similar in terms of age and gender, while later cohorts had higher BMI, lower GFR and longer ischemia time (Tab. 1). The later cohorts received organs from older donors (Tab. 1). The amount of heart transplantations performed in Sweden has increased with time (Tab. 1). Log-rank test comparing the survival curves was able to show improved survival during later eras (Fig. 1).Survival among HTx recipients has significantly improved in Sweden over time, despite less favorable recipients and donor characteristics. This was related to both reduced postoperative mortality and also improved long-time survival.

- Context Patients with adrenal insufficiency (AI) have excess mortality and morbidity, mainly due to cardiovascular (CV) diseases. The mechanisms for this is unclear. Objective To assess CV structure and function in AI patients on conventional replacement therapy and after switching to once-daily, modified-release hydrocortisone (OD-HC) in comparison with healthy matched controls. Methods This was a retrospective analysis of 17 adult AI patients (11 with primary AI, 6 with secondary AI) on stable replacement with cortisone acetate [median (minimum, maximum) 33.5 (12.5-50) mg] and, if needed, fludrocortisone [0.1 (0.05-0.2) mg], and 17 healthy matched controls. Ten patients were switched to an equivalent dose of OD-HC. Data from echocardiography, 24 h Holter-ECG and 24 h blood pressure monitoring were collected at baseline and 6 months after the switch to OD-HC. Results At baseline, AI patients had smaller left ventricular diastolic diameter (47.1 +/- 4.2 vs. 51.6 +/- 2.3 mm;P = 0.001) and left atrial diameter (34.9 +/- 4.7 vs. 38.2 +/- 2.6 cm;P = 0.018), and a higher ejection fraction (62.5 +/- 6.9% vs. 56.0 +/- 4.7%;P = 0.003) than controls. AI patients had lower nocturnal systolic and diastolic blood pressure than controls (108 +/- 15 mmHg vs. 117 +/- 8 mmHg;P = 0.038 and 65 +/- 9 mmHg vs. 73 +/- 7 mmHg;P = 0.008, respectively). After the switch to OD-HC, nocturnal diastolic blood pressure normalised. No significant changes were observed in echocardiographic and Holter-ECG parameters following the switch. Conclusions AI patients on conventional treatment display cardiovascular abnormalities that could be related to hypovolemia. Switch to OD-HC seems to have beneficial effect on blood pressure profile, but no effect on cardiovascular structure and function.

- Myocarditis is an inflammatory disease of the myocardium characterized by a great heterogeneity of presentation and evolution. Treatment of myocarditis is often supportive and the evidence for immunosuppression is scarce and debated. Conventional treatment is based on clinical presentation, ranging from conservative to advanced mechanical assist devices. In this setting, immunosuppression and immunomodulation therapies are mostly reserved for patients presenting with major clinical syndromes. In this review, we will summarise the current evidence and strategies for conventional and immunosuppressive treatments for patients presenting with acute myocarditis.

- Aims Functional mitral regurgitation (MR) (FMR) is common in heart failure with reduced ejection fraction and worsens morbidity and mortality, even when mild. The CARILLON (R) mitral contour system (Cardiac Dimensions, Kirkland, WA, USA), a mitral annuloplasty device delivered percutaneously to the coronary sinus, is designed to reduce the mitral annular dimension by virtue of the close anatomic relationship between the coronary sinus and the posterior mitral annulus. We performed a comprehensive individual patient data meta-analysis of all studies that used CARILLON (R) device vs. control that have measured mitral regurgitation severity, left ventricular (LV) remodelling, functional status, and heart failure-related outcomes in heart failure with reduced ejection fraction patients. Methods and results The Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE were searched in July 2020. Primary outcomes of interest were measures of MR severity, LV remodelling, New York Heart Association functional class and heart failure-related outcomes [mortality and heart failure hospitalization (HFH) during follow up]. All data were received as individual patient and individual time point data-points. Mean differences and 95% confidence intervals (CIs) were calculated for continuous data using a fixed-effects model. Three studies (REDUCE FMR, TITAN and TITAN II) enrolling 209 participants were identified and included. Pooled analysis showed that, compared with control, CARILLON (R) device significantly improved both MR volume (mean difference MD -9.20, 95% C.I. -16.11 to -2.29 mL, P = 0.009) and MR grade (MD -1.12, 95% CI -1.36 to -0.88, P < 0.00001) and this was associated with a significant reduction in LA volume, MD -7.54 mL, 95% CI -14.90 to - 0.18, P = 0.04. Significant LV reverse remodelling was also seen in terms of EDV (MD -16.53, 95% CI -28.61 to -44.4 mL, P = 0.007), and a trend in ESV (MD -8.68, 95% CI -18.69 to -1.34 mL, P = 0.09) but no significant effect on LVEF (MD 0.88, 95% CI -1.52% to 2.38%, P = 0.47), due presumably to the greater residual MR in the control patients falsely elevating the LVEF. In addition, the CARILLON (R) device significantly improved New York Heart Association functional Class (MD -0.22, 95% CI -0.24 to -0.16, P < 0.00001), associated with a lower rate of HFH compared with controls (45.3% vs. 64%, respectively, P = 0.04). As a sensitivity analysis we also restricted the analyses to those patients with Class 3+/4+ MR at baseline. In this cohort, the echocardiographic results were similar, and the reduction in HFH rates was even more marked (43.9% vs. 82.9%, respectively, P = 0.04). Conclusions This comprehensive meta-analysis of individual patient data has shown that CARILLON (R) device provides statistically significant and clinically meaningful benefits on MR severity, LA and LV volumes, and remodelling and rates of subsequent heart failure hospitalization

- Growth hormone (GH) therapy in heart failure (HF) is controversial. We investigated the cardiovascular effects of GH in patients with chronic HF due to ischemic heart disease.In a double-blind, placebo-controlled trial, we randomly assigned 37 patients (mean age 66years; 95% male) with ischemic HF (ejection fraction [EF]<40%) to a 9-month treatment with either recombinant human GH (1.4mg every other day) or placebo, with subsequent 3-month treatment-free follow-up. The primary outcome was change in left ventricular (LV) end-systolic volume measured by cardiac magnetic resonance (CMR). Secondary outcomes comprised changes in cardiac structure and EF. Prespecified tertiary outcomes included changes in New York Heat Association (NYHA) functional class and quality of life (QoL), as well as levels of insulin-like growth factor-1 (IGF-1) and N-terminal pro-brain natriuretic peptide (NT-proBNP).No changes in cardiac structure or systolic function were identified in either treatment group; nor did GH treatment affect QoL or functional class. In the GH group, circulating levels of IGF-1 doubled from baseline (+105%; p<0.001) and NT-proBNP levels halved (-48%; p<0.001) during the treatment period, with subsequently a partial return of both towards baseline levels. No changes in IGF-1 or NT-proBNP were observed in the placebo group at any time during the study.In patients with chronic ischemic HF, nine months of GH treatment was associated with significant increases in levels of IGF-1 and reductions in levels of NT-proBNP, but did not affect cardiac structure, systolic function or functional capacity.
