- Acute and advanced heart failure are associated with substantial adverse short- and longer-term prognosis. Both conditions necessitate complex treatment choices to restore haemodynamic stability and organ perfusion, relieve congestion, improve symptoms and allow the patient to leave the hospital and achieve an adequate quality of life. Among the available intravenous vasoactive therapies, inotropes constitute an option when an increase in cardiac contractility is needed to reverse a low output state. Within the inotrope category, levosimendan is well suited to the needs of both sets of patients since, in contrast to conventional adrenergic inotropes, it has not been linked in clinical trials or wider clinical usage with increased mortality risk and retains its efficacy in the presence of beta-adrenergic receptor blockade; it is further believed to possess beneficial renal effects. The overall haemodynamic profile and clinical tolerability of levosimendan, combined with its extended duration of action, have encouraged its intermittent use in patients with advanced heart failure. This paper summarises the key messages derived from a series of 12 tutorials held at the Heart Failure 2019 congress organised in Athens, Greece, by the Heart Failure Association of the European Society of Cardiology.

- Background Cardiac allograft vasculopathy (CAV) limits survival after heart transplantation, and the effect of different immunosuppressive regimens on CAV is not fully understood. The randomized SCHEDULE trial (Scandinavian Heart Transplant Everolimus De Novo Study With Early Calcineurin Inhibitors Avoidance) evaluated whether initiation of the proliferation signal inhibitor everolimus and early cyclosporine elimination can reduce CAV development. Methods and Results The SCHEDULE trial was a multicenter Scandinavian trial, where 115 de novo heart transplantation recipients were randomized to everolimus with complete cyclosporine withdrawal 7 to 11 weeks after heart transplantation or standard cyclosporine-based immunosuppression. Seventy-six (66%) patients had matched intravascular ultrasound examinations at baseline and 12 and 36 months. Intravascular ultrasound analysis evaluated maximal intimal thickness, percent atheroma volume, and total atheroma volume. Qualitative plaque analysis using virtual histology assessed fibrous, fibrofatty, and calcified tissue as well as necrotic core. Serum inflammatory markers were measured in parallel. The everolimus group (n=37) demonstrated significantly reduced CAV progression as compared with the cyclosporine group (n=39) at 36 months (Δ maximal intimal thickness, 0.09±0.05 versus 0.15±0.16 mm [ P=0.03]; Δ percent atheroma volume, 5.3±2.8% versus 7.6±5.9% [ P=0.03]; and Δ total atheroma volume, 33.9±71.2 versus 54.2±96.0 mm3 [ P=0.34], respectively]. At 36 months the number of everolimus patients with rejection graded ≥2R was 15 (41%) as compared with 5 (13%) in the cyclosporine group ( P=0.01). Everolimus did not affect CAV morphology or immune marker activity during the follow-up period. Conclusions The SCHEDULE trial demonstrates that everolimus initiation and early cyclosporine elimination significantly reduces CAV progression at 12 months, and this beneficial effect is clearly sustained at 36 months.

Tidskriftsartikel (refereegranskat)abstract
- Right ventricular failure in patients treated using left ventricular assist devices is associated with poor outcomes. We assessed the strategy of preplanned biventricular assist device implantation in patients with a high risk for right ventricular failure.Between 2010 and 2014, we assigned 20 patients to preplanned biventricular assist device and 21 patients to left ventricular assist device as a bridge to heart transplantation on the basis of the estimated risk of postimplant right ventricular failure. Preimplant characteristics and postimplant outcomes were compared between the 2 groups.Patients with a biventricular assist device were younger, more often female, and more frequently had nonischemic heart disease than left ventricular assist device recipients. At preoperative assessment, biventricular assist device recipients had poorer Interagency Registry for Mechanically Assisted Circulatory Support profiles, a lower cardiac index, and more compromised right ventricular function. Survival on device to heart transplantation/weaning/destination for biventricular assist device and left ventricular assist device recipients was 90% versus 86% (not significant), with shorter heart transplantation waiting times for biventricular assist device recipients (median days, 154 vs 302, P<.001). Overall survival at 1year was 85% (95% confidence interval, 62-95) versus 86% (95% confidence interval, 64-95) (not significant). The majority of both biventricular assist device and left ventricular assist device recipients could be discharged to home during the heart transplantation waiting time (55% vs 71%, not significant), and complication rates on device were comparable between groups (major stroke 10% vs 10%, not significant).Planned in advance, the biventricular assist device seems to be a feasible option as bridge to heart transplantation for patients with a high risk of postimplant right ventricular failure. The outcomes for these patients were similarto those observed for contemporary left ventricular assist device recipients, despite those receiving biventricular assist devices being more severely ill.

- Heart transplantation (HTx) has become the standard treatment for patients with end-stage heart disease. We report on the long-term outcome after HTx at our centre and investigate trends in outcome over time.During the period, between 1984 and 2014, a total of 610 HTx procedures were performed in 595 patients (median 48years; IQR 31-57years; range 24days-71years; mean 43years; 75% male) in our institution. Long-term outcome was investigated in the whole cohort, among children (n=76), bridged with mechanical circulatory support (MCS, n=131), re-transplanted (n=17), and concomitant kidney transplantation (n=12).Long-term survival was at 1, 5, 10, 15 and 20years: 86% (95CI 0.83-0.89); 77% (95CI 0.73-0.80); 63% (95CI 0.59-0.68); 48% (95CI 0.43-0.54) and 30% (95CI 0.25-0.36), respectively. The median survival for the whole cohort was 14.1years. Patients transplanted during the most recent time period (2010-2014) had a better survival compared to previous eras, with a 1- and 3-year survival of 94% (95CI 0.89-0.97) and 93% (95CI 0.88-0.96), respectively (p<0.001). However, when survival was analysed for long-term MCS (n=80) versus short term MCS (n=35), there was a significantly poorer survival for the short-term MCS group (p=0.001). Independent predictors of long-term mortality included recipient age (p=0.041); previous smoking (p=0.034); ischemic heart disease (p=0.002); and preoperative ventilator therapy (p=0.004).We have shown that continuous improvement in outcome after HTx still occurs. In the last time era, direct transplantation from short-term MCS was abandoned, which may have inflicted outcome during the last time era.

Tidskriftsartikel (refereegranskat)abstract
- We report the case of a 38-year-old man who presented with cardiac arrest 1 year after curative liver transplantation for Wilson's disease. Clinical work-up proofed myocardial copper and iron accumulation using mass spectrometry, which led most likely to myocardial fibrosis as visualized by cardiovascular magnetic resonance (unprecedented delayed enhancement pattern) and endomyocardial biopsy. Consequently, cardiac arrest due to ventricular fibrillation and subsequent episodes of sustained ventricular tachycardia were considered as primary cardiac manifestation of Wilson's disease. This can, as illustrated by our case, occur even late after curative liver transplantation, which is an important fact that treating physicians should be aware of during clinical follow-up of these patients.

- The NOCTET study randomized 282 patients ≥1 year after heart or lung transplantation to continue conventional calcineurin inhibitor (CNI) therapy or to start everolimus with reduced-exposure CNI. Last follow-up, at ≥5 years postrandomization (mean: 5.6 years) was attended by 72/140 everolimus patients (51.4%) and 91/142 controls (64.1%). Mean measured GFR remained stable in the everolimus group from randomization (51.3 ml/min) to last visit (51.4 ml/min) but decreased in controls (from 50.5 ml/min to 45.3 ml/min) and was significantly higher with everolimus at last follow-up (P = 0.004). The least squares mean (SE) change from randomization was -1.5 (1.7)ml/min with everolimus versus -7.2 (1.7)ml/min for controls (difference: 5.7 [95% CI 1.7; 9.6]ml/min; P = 0.006). The difference was accounted for by heart transplant patients (difference: 6.9 [95% 2.3; 11.5]ml/min; P = 0.004). Lung transplant patients showed no between-group difference at last follow-up. Rates of rejection, death, and major cardiac events were similar between groups, as was graft function. Pneumonia was more frequent with everolimus (18.3% vs. 6.4%). In conclusion, introducing everolimus in maintenance heart transplant patients, with reduced CNI, achieves a significant improvement in renal function which is maintained for at least 5 years, but an early renal benefit in lung transplant patients was lost. Long-term immunosuppressive efficacy was maintained.

Parvovirus B19 in Endomyocardial Biopsy of Patients With Idiopathic Dilated Cardiomyopathy: Foe or Bystander?

Tidskriftsartikel (refereegranskat)abstract
- Parvovirus B19 (PVB19) has emerged as one of the viruses possibly inducing chronic myocarditis and subsequent idiopathic dilated cardiomyopathy (IDCM). The aim of this work was to investigate the presence and long-term consequences of PVB19-DNA within myocardial biopsies from patients with IDCM and to compare the findings with those from donor hearts (control group).Forty hospitalized IDCM patients (age 47 ± 12 y) with mean left ventricular ejection fraction 27 ± 12% were included. The presence of PVB19-DNA in myocardial biopsies and of IgG and IgM antibodies in patient sera was analyzed. The control group consisted of 20 donor hearts. The follow-up time was 112 ± 57 months. PVB19-DNA was found in myocardial biopsies of both patients (73%) and control samples (55%; P=.25).Three deaths and 8 heart transplantations occurred in the IDCM group, and 6 deaths in the control group (ie, the recipients of the control hearts). No difference in transplantation-free survival between the PVB19-DNA positive/negative IDCM patients or transplant recipients was found.PVB19-DNA is a common finding in both patients with IDCM and in healthy donor hearts, not affecting prognosis. These findings support the view that PVB19 is an innocent bystander, frequently found in myocardium with low DNA copies, and not a plausible cause of IDCM.

- In this review, the importance of growth hormone (GH) for the maintenance of normal cardiac function in adult life is discussed. Physiological effects of GH and underlying mechanisms for interactions between GH and insulin-like growth factor I (IGF-I) and the cardiovascular system are covered as well as the cardiac dysfunction caused both by GH excess (acromegaly) and by GH deficiency in adult hypopituitary patients. In both acromegaly and adult GH deficiency, there is also increased cardiovascular morbidity and mortality possibly linked to aberrations in GH status. Finally, the status of the GH/IGF-I system in relation to heart failure and the potential of GH as a therapeutic tool in the treatment of heart failure are reviewed in this article.

Tidskriftsartikel (refereegranskat)abstract
- Obesity is a risk factor for atrial fibrillation, which in turn is associated with stroke, heart failure, and increased all-cause mortality.The authors investigated whether weight loss through bariatric surgery may reduce the risk of new-onset atrial fibrillation.SOS (Swedish Obese Subjects) is a prospective matched cohort study conducted at 25 surgical departments and 480 primary healthcare centers in Sweden. The cohort was recruited between 1987 and 2001. Among 4,021 obeseindividuals with sinus rhythm and no history of atrial fibrillation, 2,000 underwent bariatric surgery (surgery group), and 2,021 matched obese control subjects received usual care (control group). The outcome, first-time atrial fibrillation, was ascertained by crosschecking the SOS database with the Swedish National Patient Register on inpatientand outpatient diagnosis codes.During a median follow-up of 19 years, first time atrial fibrillation occurred in 247 patients (12.4%) in the surgical group, and in 340 (16.8%) control subjects. The risk of developing atrial fibrillation was 29% lower in the surgery group versus the control group (hazard ratio: 0.71; 95% confidence interval: 0.60 to 0.83; p< 0.001). Younger individuals benefited more from surgical intervention than those who were older (p value for interaction 0.001). Also, those with a high diastolic blood pressure benefitted more from surgery than did those with a low diastolic blood pressure (p for interaction= 0.028).Compared with usual care, weight loss through bariatric surgery reduced the risk of atrial fibrillationamong persons being treated for severe obesity. The risk reduction was more apparent in younger people and in thosewith higher blood pressure.
