  • Interdialytic weight gain of less than 2.5% seems to limit cardiac damage during hemodialysis
  • 2021
  • record:In_t: International Journal of Artificial Organs. - : SAGE Open. - 0391-3988 .- 1724-6040. ; 44:8, s. 539-550
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Aims: To investigate if a single low-flux HD induces a rise in cardiac biomarkers and if a change in clinical approach may limit such mechanism.Material and methods: A total of 20 chronic HD patients each underwent three different study-dialyses. Dialyzers (low-flux polysulfone, 1.8 sqm) had been stored either dry or wet (Wet) and the blood level in the venous chamber kept low or high. Laboratory results were measured at baseline, 30 and 180 min, adjusted for the effect of fluid shift. Ultrasound measured microemboli signals (MES) within the return line.Results: Hemodialysis raised cardiac biomarkers (p < 0.001): Pentraxin 3 (PTX) at 30 min (by 22%) and at 180 min PTX (53%), Pro-BNP (15%), and TnT (5%), similarly for all three HD modes. Baseline values of Pro-BNP correlated with TnT (rho = 0.38, p = 0.004) and PTX (rho = 0.52, p < 0.001). The changes from pre- to 180 min of HD (delta-) were related to baseline values (Pro-BNP: rho = 0.91, p < 0.001; TnT: rho = 0.41, p = 0.001; PTX: rho = 0.29, p = 0.027). Delta Pro-BNP (rho = 0.67, p < 0.001) and TnT (rho = 0.38, p = 0.004) correlated with inter-dialytic-weight-gain (IDWG). Biomarkers behaved similarly between the HD modes. The least negative impact was with an IDWG <= 2.5%. Multiple regression analyses of the Wet-High mode does not exclude a relation between increased exposure of MES and factors such as release of Pro-BNP.Conclusion: Hemodialysis, independent of type of dialyzer storage, was associated with raised cardiac biomarkers, more profoundly in patients with higher pre-dialysis values and IDWG. A limitation in IDWG to <2.5% and prolonged ultrafiltration time may limit cardiac strain during HD, especially in patients with cardiovascular risk.

  • Dyssynchrony and electromechanical delay are associated with focal fibrosis in the systemic right ventricle - Insights from echocardiography.
  • 2016
  • record:In_t: International Journal of Cardiology. - : Elsevier BV. - 0167-5273 .- 1874-1754. ; 220, s. 382-388
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • BACKGROUND: Systemic right ventricular (RV) dysfunction and sudden cardiac death remain problematic late after Mustard operation for transposition of the great arteries. The exact mechanism for that relationship is likely to be multifactorial including myocardial fibrosis. Doppler echocardiography gives further insights into the role of fibrosis shown by late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) in late morbidity.METHODS AND RESULTS: Twenty-two consecutive patients, mean age 28±8years, were studied with 2D echocardiography, and also assessed by LGE CMR. The presence of LGE in 13/22 patients (59%) was related to delayed septal shortening and lengthening (P=0.002 &P=0.049), prolonged systemic RV isovolumic contraction time (P=0.024) and reduced systemic RV free wall and septal excursion (P=0.027 &P=0.005). The systemic RV total isovolumic time was prolonged but not related to extent of LGE. LGE extent was related to markers of electromechanical delay and dyssynchrony (delayed onset of RV free wall shortening and lengthening; r=0.73 &P=0.004 and r=0.62 &P=0.041, respectively, and QRS duration r=0.68, P<0.01) and was inversely related to systolic RV free wall shortening velocity (r=-0.59 &P=0.042). The presence of LGE was also related to lower exercise capacity, ≥mild tricuspid regurgitation and more arrhythmia (P=0.008, P=0.014 and P=0.040). RV free wall excursion and systolic tissue Doppler velocity were related to CMR derived RV ejection fraction (r=0.51, P=0.015, and r=0.77, P=<0.001, respectively).CONCLUSION: Post Mustard repair, myocardial fibrosis is related to dyssynchrony, RV long axis dysfunction and tricuspid regurgitation. Echocardiographic measurements of systemic RV function can be confidently used in serial follow-up following Mustard operation.

  • Biomarkers predict in-hospital major adverse cardiac events in covid-19 patients : A multicenter international study
  • 2021
  • record:In_t: Journal of Clinical Medicine. - : MDPI. - 2077-0383. ; 10:24
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Background: The COVID-19 pandemic carries a high burden of morbidity and mortality worldwide. We aimed to identify possible predictors of in-hospital major cardiovascular (CV) events in COVID-19.Methods: We retrospectively included patients hospitalized for COVID-19 from 10 centers. Clinical, biochemical, electrocardiographic, and imaging data at admission and medications were collected. Primary endpoint was a composite of in-hospital CV death, acute heart failure (AHF), acute myocarditis, arrhythmias, acute coronary syndromes (ACS), cardiocirculatory arrest, and pulmonary embolism (PE).Results: Of the 748 patients included, 141(19%) reached the set endpoint: 49 (7%) CV death, 15 (2%) acute myocarditis, 32 (4%) sustained-supraventricular or ventricular arrhythmias, 14 (2%) cardiocirculatory arrest, 8 (1%) ACS, 41 (5%) AHF, and 39 (5%) PE. Patients with CV events had higher age, body temperature, creatinine, high-sensitivity troponin, white blood cells, and platelet counts at admission and were more likely to have systemic hypertension, renal failure (creatinine ≥ 1.25 mg/dL), chronic obstructive pulmonary disease, atrial fibrillation, and cardiomyopathy. On univariate and multivariate analysis, troponin and renal failure were associated with the composite endpoint. Kaplan–Meier analysis showed a clear divergence of in-hospital composite event-free survival stratified according to median troponin value and the presence of renal failure (Log rank p < 0.001).Conclusions: Our findings, derived from a multicenter data collection study, suggest the routine use of biomarkers, such as cardiac troponin and serum creatinine, for in-hospital prediction of CV events in patients with COVID-19.

  • Carotid IM-GSM is better than IMT for identifying patients with multiple arterial disease
  • 2018
  • record:In_t: Scandinavian Cardiovascular Journal. - : Taylor & Francis Group. - 1401-7431 .- 1651-2006. ; 52:2, s. 93-99
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Objective. Atherosclerosis is a systemic inflammatory disease that can affect more than one arterial bed simultaneously. The aim of this study was to determine the relationship between ultrasound markers of atherosclerosis and multiple arterial disease. Design. We have included 87 currently asymptomatic carotid disease patients (mean age 69 +/- 6 year, 34% females) in this study. Intima media thickness (IMT) and intima media-grey scale median (IM-GSM) were measured in the common carotid artery (CCA), and correlated with previous and/or current atherosclerotic vascular disease in the coronary, carotid and lower extremities. Patients were divided into three groups: (1) asymptomatic, (2) previous symptoms in one arterial territory and (3) previous symptoms in multiple arterial territories. Results. Patients with previous disease in the coronary arteries had higher IMT (p=.034) and lower IM-GSM (p<.001), and those with prior stroke had lower IM-GSM (p=.007). Neither IMT nor IM-GSM was different between patients with and without previous lower extremity vascular disease. IM-GSM was significantly different between groups, it decreased significantly with increasing number of arterial territories affected (37.7 +/- 15.4 vs. 29.3 +/- 16.4 vs. 20.7 +/- 12.9) p<.001, for asymptomatic, symptoms in one and in multiple arterial systems, respectively. Conventional IMT was not significantly different between groups p=.49. Conclusion. Carotid IMT was higher and IM-GSM lower in patients with symptomatic nearby arterial territories but not in those with peripheral disease. In contrast to conventional IMT, IM-GSM can differentiate between numbers of arterial territories affected by atherosclerosis, suggesting that it is a better surrogate for monitoring multiple arterial territory disease.

  • Carotid plaque echogenicity predicts cerebrovascular symptoms : a systematic review and meta-analysis
  • 2016
  • record:In_t: European Journal of Neurology. - : Wiley. - 1351-5101 .- 1468-1331. ; 23:7, s. 1241-1247
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Background and purpose: Many reports have shown an association between hypoechoic (echolucent) carotid atherosclerotic plaques and unstable features. In this meta-analysis our aim was to determine the role of carotid plaque echogenicity in predicting future cerebrovascular (CV) symptoms.Methods: Electronic databases (PubMed, MEDLINE, EMBASE and Cochrane Center Register) up to September 2015 were systematically searched. Studies with ultrasound-based characterization of carotid artery plaque echogenicity and its association with focal neurological symptoms of vascular origin were eligible for analysis. In the meta-analysis, heterogeneity was measured usingI2 statistics and publication bias was evaluated using the Begg–Mazumdar test. In addition several comparisons between subgroups were performed.Results: Of 1387 identified reports, eight studies with asymptomatic patients and three studies with symptomatic patients were meta-analyzed. Pooled analysis showed an association between echolucent carotid plaques and future CV events in asymptomatic patients [relative risk 2.72 (95% confidence interval 1.86–3.96)] and recurrent symptoms in symptomatic patients [relative risk 2.97 (95% confidence interval 1.85–4.78)]. The association was preserved for all stenosis degrees in asymptomatic patients, whilst patients with echolucent plaques and severe stenosis were at higher risk of future events. Also, computer-assisted methods for assessment of carotid plaque echogenicity and studies analyzing ultrasound data collected after the year 2000 showed better prediction.Conclusions: In asymptomatic and symptomatic patients, analysis of carotid plaque echogenicity could identify those at high risk of CV events.

  • Development of cardiomyopathy after liver transplantation in Swedish hereditary transthyretin amyloidosis (ATTR) patients
  • 2011
  • record:In_t: Amyloid. - London : Informa Healthcare. - 1350-6129 .- 1744-2818. ; 18:4, s. 200-205
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Background: Recent studies of liver transplanted (LTx) familial amyloidotic polyneuropathy (FAP) patients have shown a progression of cardiomyopathy in some patients after LTx, but knowledge of the underlying factors remains limited.Methods: Seventy-five patients, who had undergone LTx from 1996 to 2008, were included. They had all been examined by echocardiography 1-16 months before LTx. Fifty-four had been re-examined 7-34 months, and forty-two 36-137 months after LTx.Results: A significant increase in interventricular septum (IVS) thickness occurred after LTx (p < 0.01), particularly in males (p = 0.002) and late onset patients (p = 0.003). The development of post-LTx cardiomyopathy was related to patient's age at onset of the disease, male gender and pre-LTx IVS thickness. On multivariate regression analysis, however, age at onset was the only significant predictor for the development of cardiomyopathy (odds ratio = 1.14, 95% confident interval 1.01-1.30, p = 0.04).Conclusion: An increase of IVS thickness can be observed in FAP patients after LTx. Age at onset of the disease is the main predictor for increased IVS thickness and for the development of cardiomyopathy after liver transplantation.

  • Time trends in ischaemic heart disease incidence and mortality over three decades (1990-2019) in 20 Western European countries: systematic analysis of the Global Burden of Disease Study 2019
  • 2022
  • record:In_t: European Journal of Preventive Cardiology. - : Oxford University Press. - 2047-4873 .- 2047-4881. ; 29:2, s. 396-403
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • AIMS: To investigate and compare changes in the rates of ischaemic heart disease (IHD) incidence and mortality between 1990 and 2019 in 20 high-income Western European countries with similar public health systems and low cardiovascular risk.METHODS AND RESULTS: The 2020 updated version of the Global Burden of Disease database was searched. Variability and differences in IHD incidence and mortality rates (per 100 000) between countries over time, were calculated. A piecewise linear (join point) regression model was used to identify the slopes of these trends and the points in time at which significant changes in the trends occur. Ischaemic heart disease incidence and mortality rates varied widely between countries but decreased for all between 1990 and 2019. The relative change was greater for mortality than for incidence. Ischaemic heart disease incidence rates declined by approximately 36% between 1990 and 2019, while mortality declined by approximately 60%. Breakpoint analysis showed that the largest decreases in incidence and mortality occurred between 1990 and 2009 (-32%, -52%, respectively), with a much slower decrease after that (-5.9%, -17.6%, respectively), and even a slight increase for some countries in recent years. The decline in both incidence and mortality was lower in the Mediterranean European countries compared to the Nordic and Central European regions.CONCLUSIONS: In the Western European countries studied, the decline in age-standardized IHD incidence over three decades was slower than the decline in age-standardized IHD mortality. Decreasing trends of both IHD incidence and mortality has substantially slowed, and for some countries flattened, in more recent years.

  • Right ventricular involvement in transthyretin amyloidosis
  • 2018
  • record:In_t: Amyloid. - : Taylor & Francis. - 1350-6129 .- 1744-2818. ; 25:3, s. 160-166
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Background: The extent of right ventricular (RV) involvement in transthyretin amyloidosis (ATTR) is unknown.Objectives: This study sought to establish the degree of RV involvement in ATTR amyloidosis, and compare findings with RV involvement in hypertrophic cardiomyopathy (HCM).Methods: Forty-two patients with ATTR amyloidosis and echocardiographic evidence of cardiac amyloidosis (cardiac ATTR), 19 ATTR patients with normal left ventricular (LV) wall thickness (non-cardiac ATTR), 25 patients with diagnosed HCM and 30 healthy controls were included in this study. Echocardiographic measurements for conventional parameters, as well as RV global and segmental strain, were recorded.Results: When comparing RV structure and function between cardiac ATTR amyloidosis and HCM patients, only segmental strain differed between the two groups. In cardiac ATTR amyloidosis, we found an RV apex-to-base strain gradient with highest deformation in the apex. This pattern was reversed in patients with HCM.Conclusions: RV involvement is common in cardiac ATTR patients. The present study also detected an RV apical sparing pattern in patients with ATTR cardiomyopathy, similar to what has previously been described for the left ventricle in these patients. This pattern was not seen in HCM patients. Further studies are needed to assess the clinical importance of these findings.

  • Replication of LC-MS untargeted lipidomics results in patients with calcific coronary disease : an interlaboratory reproducibility study
  • 2016
  • record:In_t: International Journal of Cardiology. - : Elsevier. - 0167-5273 .- 1874-1754. ; 222, s. 1042-1048
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • BACKGROUND: Recently a lipidomics approach was able to identify perturbed fatty acyl chain (FAC) and sphingolipid moieties that could stratify patients according to the severity of coronary calcification, a form of subclinical atherosclerosis. Nevertheless, these findings have not yet been reproduced before generalising their application. The aim of this study was to evaluate the reproducibility of lipidomics approaches by replicating previous lipidomic findings in groups of patients with calcific coronary artery disease (CCAD).METHODS: Patients were separated into the following groups based on their calcium score (CS); no calcification (CS: 0; n=26), mild calcification (CS: 1-250; n=27) and severe calcification (CS: >250; n=17). Two serum samples were collected from each patient and used for comparative analyses by 2 different laboratories, in different countries and time points using liquid chromatography coupled to mass spectrometry untargeted lipidomics methods.RESULTS: Six identical metabolites differentiated patients with severe coronary artery calcification from those with no calcification were found by both laboratories independently. Additionally, relative intensities from the two analyses demonstrated high correlation coefficients. Phosphatidylcholine moieties with 18-carbon FAC were identified in lower intensities and 20:4 FAC in higher intensities in the serum of diseased group. Moreover, 3 common sphingomyelins were detected.CONCLUSION: This is the first interlaboratory reproducibility study utilising lipidomics applications in general and specifically in patients with CCAD. Lipid profiling applications in patients with CCAD are very reproducible in highly specialised and experienced laboratories and could be applied in clinical practice in order to spare patients diagnostic radiation.

  • Amyloid Fibril Composition as a Predictor of Development of Cardiomyopathy After Liver Transplantation for Hereditary Transthyretin Amyloidosis
  • 2012
  • record:In_t: Transplantation. - 0041-1337 .- 1534-6080. ; 93:10, s. 1017-1023
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Background. Liver transplantation (LTx) is an accepted treatment for hereditary transthyretin (TTR) amyloidosis (ATTR). However, unforeseen heart complications, especially a rapid development of cardiomyopathy after LTx has affected mortality and morbidity. Recently, a relationship between ATTR-fibril composition and cardiomyopathy has been noted. The aim of this study was to investigate whether development of cardiomyopathy and heart failure in LTx ATTR amyloid patients is related to amyloid fibril composition.Methods. Twenty-four patients with hereditary ATTR amyloidosis who had undergone LTx and have had their amyloid fibril type tested were available for the study. They had been examined by echocardiography including tissue Doppler and speckle tracking echocardiography before and after LTx. Patients were divided into two groups according to fibril composition, 10 patients with type A fibrils (a mixture of truncated and full-length TTR) and 14 patients with type B fibrils (full-length TTR fibrils only). There was no difference in time to the follow-up echocardiography between the two groups.Results. After LTx, the group consisting of type A patients developed symptoms of heart failure and with reduced systolic and diastolic ventricular function as shown by echocardiography, whereas no similar deterioration was noted for the group of patients with type B fibrils.Conclusion. Patients with type A fibrils deteriorate an already existing cardiomyopathy and heart failure after LTx, in contrast to patients with type B fibrils. These results might have significant clinical implications in optimizing best patients selection criteria for LTx.
