Abstract Aims The initial and dynamic levels of B‐type natriuretic peptide (BNP) and N‐terminal‐prohormone BNP (NT‐proBNP) are routinely used in clinical practice to identify patients with acute and chronic heart failure. In addition, BNP/NT‐proBNP levels might be useful for risk stratification in patients with and without heart failure. We performed a meta‐analysis to investigate, whether the value of BNP/NT‐proBNP as predictors of long‐term prognosis differentiates in cohorts with and without heart failure. Methods and results We systematically searched established scientific databases for studies evaluating the prognostic value of BNP or NT‐proBNP. Random effect models were constructed. Data from 66 studies with overall 83 846 patients (38 studies with 46 099 patients with heart failure and 28 studies with 37 747 patients without heart failure) were included. In the analysis of the log‐transformed BNP/NT‐proBNP levels, an increase in natriuretic peptides by one standard deviation was associated with a 1.7‐fold higher MACE rate (hazard ratio [95% confidence interval]: 1.74[1.58–1.91], P

Abstract Aims While immune checkpoint inhibitor (ICI) therapy significantly improves survival rates in advanced melanoma, ICI can evoke severe immune‐related cardiovascular adverse events. Right ventricular (RV) dysfunction negatively impacts the outcomes in cardiovascular diseases and may be an early sign for overall cardiotoxicity. We aimed to assess RV function in melanoma patients undergoing ICI therapy using conventional echocardiographic and strain imaging techniques. Methods and results We retrospectively examined 30 patients (40% women, age 59 ± 13 years) with advanced melanoma (stage III/IV) before and 4 weeks after the start of ICI therapy (follow‐up at 39 ± 15 days); n = 15 of the patients received nivolumab, and n = 15 received the combination therapy nivolumab/ipilimumab. Two‐dimensional echocardiography with assessment of RV longitudinal strain of the free wall (RV‐LSFW) and assessment of right atrial (RA) strain from speckle tracking was performed at baseline and after the start of ICI therapy. Short‐term ICI therapy caused a reduction of RV‐LSFW (−25.5 ± 6.4% vs. −22.4 ± 4.3%, P = 0.002) and of RA strain during contraction phase (−10.6 ± 3.5% vs. −7.7 ± 3.1%, P = 0.001). Conventional parameters including tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), and pulmonary artery systolic pressure were not different between the two time points (TAPSE 26 ± 5 vs. 25 ± 5 mm, P = 0.125; FAC 38 ± 13% vs. 38 ± 14%, P = 0.750; and pulmonary artery systolic pressure 27 ± 10 vs. 25 ± 8 mmHg, P = 0.268). Conclusions Analysis of RV and RA strain shows alterations even in a short‐term follow‐up, while changes in RV function are not visible by conventional RV parameters. Alterations in RV and RA strain could be early signs of cardiotoxicity and therefore should be assessed in patients undergoing ICI therapy.

Abstract Coronavirus disease 2019 (COVID‐19) is challenging the care for cardiovascular patients, resulting in serious consequences with increasing mortality in pre‐diseased heart failure patients. In the current state of the pandemic, the physiopathology of COVID‐19 affecting pre‐diseased hearts and the management of terminal heart failure in COVID‐19 patients remain unclear. We outline the findings of a young COVID‐19 patient suffering from idiopathic cardiomyopathy who was treated for acute multi‐organ failure and required cardiac surgery with implantation of a temporary right ventricular and durable left ventricular assist device (LVAD). For deeper translational insights, we used in‐depth tissue analysis by electron and light sheet fluorescence microscopy revealing evidence for spatial distribution of severe acute respiratory syndrome coronavirus 2 in the heart. This indicates that in‐depth analysis may represent a valuable tool in understanding indistinct clinical cases. We conclude that COVID‐19 directly affects pre‐diseased hearts, but the consequences can be treated successfully with LVAD implantation.

Abstract Aims Childhood cancer therapy is associated with a significant risk of therapy‐related cardiotoxicity. This meta‐analysis aims to evaluate cardiac biomarkers for the detection of cancer therapy‐related left ventricular (LV) dysfunction in childhood cancer patients. Methods and results PubMed, Cochrane Library, Wiley Library, and Web of Science were screened for studies investigating brain natriuretic peptide (BNP)/N‐terminal proBNP (NT‐proBNP) or cardiac troponin in childhood cancer patients. The odds ratios (OR) for elevation of cardiac biomarkers and association with LV dysfunction were calculated using a random‐effects model. Data from 27 studies with 1651 subjects were included. BNP/NT‐proBNP levels were higher post‐treatment compared with controls or pre‐treatment values [standardized mean difference = 1.0; 95% confidence interval (CI) = 0.6–1.4; n = 320; P

Abstract Aims Conventional cytotoxic chemotherapy is still among the most effective treatment options for many types of cancer. However, cardiotoxicity, notably the decrease in left ventricular function under these regimens, can impair prognosis. Thus, prevention and treatment of cardiotoxicity are crucial. The present meta‐analysis aims to assess the efficacy of beta‐blockers or angiotensin‐converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARBs) for prevention of cardiotoxicity. Methods and results We systematically searched Pubmed, Cochrane, EMBASE, and Web of Science databases for randomized controlled trials published until February 2019. The analysis included randomized studies that reported on left ventricular ejection fraction (LVEF) after 6 months of chemotherapy in cancer patients who received beta‐blockers or ACE inhibitors/ARBs for prevention of cardiotoxicity compared with controls. Studies on combination cardioprotective therapies were excluded from the analysis. The primary endpoint was prevention of a decrease in LVEF as defined by the individual study and as assessed by either transthoracic echocardiography or magnetic resonance imaging. We here show that patients under anthracycline‐based chemotherapy have a moderate yet significant benefit in LVEF from beta‐blockers or ACEs/ARBs. The beta‐blocker analysis included 769 cancer patients, and the ACE inhibitors/ARBs analysis included a total of 581 cancer patients. The mean LVEF difference between the beta‐blocker group and the control group was 2.57% (95% confidence interval 0.63–4.51, P = 0.009). The mean difference for ACE inhibitors/ARBs was 4.71% (95% confidence interval 0.38–9.03, P = 0.03). However, the beneficial effects throughout the studies were variable as documented by significant heterogeneity between the studies. Conclusions Systematic evidence is needed to solidly found recommendations for cardioprotective prevention during chemotherapy. Likewise, trials on other neurohumoral drugs (spironolactone) and lipid‐lowering approaches are required to improve protection for cardio‐oncology patients.
