BACKGROUND: Gastrointestinal (GI) bleeding is one of the most common complications after continuous-flow left ventricular assist device implantation. More than one third of patients with incident bleed go on to develop recurrent GI bleeding. Octreotide, a somatostatin analog, is proposed to reduce the risk of recurrent GI bleeding in this population. METHODS AND RESULTS: This multicenter, retrospective analysis evaluated 51 continuous-flow left ventricular assist device patients who received secondary prophylaxis with octreotide after their index GI bleed from 2009 to 2015...

BACKGROUND: An enhanced inflammatory response predicts worse outcomes in heart failure (HF). We hypothesized that administration of IL-1 (interleukin-1) receptor antagonist (anakinra) could inhibit the inflammatory response and improve peak aerobic exercise capacity in patients with recently decompensated systolic HF. METHODS AND RESULTS: We randomly assigned 60 patients with reduced left ventricular ejection fraction (<50%) and elevated C-reactive protein levels (>2 mg/L), within 14 days of hospital discharge, to daily subcutaneous injections with anakinra 100 mg for 2 weeks, 12 weeks, or placebo...

BACKGROUND: Chagas' disease is an important cause of cardiomyopathy in Latin America. We aimed to compare clinical characteristics and outcomes in patients with heart failure (HF) with reduced ejection fraction caused by Chagas' disease, with other etiologies, in the era of modern HF therapies. METHODS AND RESULTS: This study included 2552 Latin American patients randomized in the PARADIGM-HF (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) and ATMOSPHERE (Aliskiren Trial to Minimize Outcomes in Patients With Heart Failure) trials...

BACKGROUND: Diabetes mellitus (DM) is a risk factor for morbidity and mortality in patients with heart failure. The effect of DM on post-left ventricular assist device (LVAD) implantation outcomes is unclear. This study sought to investigate whether patients with DM had worse outcomes than patients without DM after LVAD implantation and whether LVAD support resulted in a better control of DM. METHODS AND RESULTS: We retrospectively reviewed 341 consecutive adults who underwent implantation of LVAD from 2007 to 2016...

BACKGROUND: To assess the current landscape of the heart failure (HF) epidemic and provide targets for future health policy interventions in Medicare, a contemporary appraisal of its epidemiology across inpatient and outpatient care settings is needed. METHODS AND RESULTS: In a national 5% sample of Medicare beneficiaries from 2002 to 2013, we identified a cohort of 2 331 939 unique fee-for-service Medicare beneficiaries ≥65-years-old followed for all inpatient and outpatient encounters over a 10-year period (2004-2013)...

BACKGROUND: Persistent low-level hemolysis (LLH) during continuous-flow mechanical circulatory support is associated with subsequent thrombosis. Free hemoglobin from ongoing hemolysis scavenges nitric oxide (NO) to create an NO deficiency which can augment platelet function leading to a prothrombotic state. The phosphodiesterase-5 inhibitor, sildenafil, potentiates NO signaling to inhibit platelet function. Accordingly, we investigated the association of sildenafil administration and thrombotic events in patients with LLH during Heart Mate II support...

BACKGROUND: Clinical trials have established the average benefit of cardiac resynchronization therapy (CRT), but estimating benefit for individual patients remains difficult because of the heterogeneity in treatment response. Accordingly, we created a multivariable model to predict changes in quality of life (QoL) with and without CRT. METHODS AND RESULTS: Patient-level data from 5 randomized trials comparing CRT with no CRT were used to create a prediction model of change in QoL at 3 months using a partial proportional odds model for no change, small, moderate, and large improvement, or deterioration of any magnitude...

BACKGROUND: Omecamtiv mecarbil (OM) enhances systolic function in vivo by directly binding the myosin cross-bridges (XBs) in the sarcomere. However, the mechanistic details governing OM-induced modulation of XB behavior in failing human myocardium are unclear. METHODS AND RESULTS: The effects of OM on steady state and dynamic XB behavior were measured in chemically skinned myocardial preparations isolated from human donor and heart failure (HF) left ventricle. HF myocardium exhibited impaired contractile function as evidenced by reduced maximal force, magnitude of XB recruitment (Pdf), and a slowed rate of XB detachment (krel) at submaximal Ca(2+) activations...

BACKGROUND: A diagnosis of heart failure (HF) often requires a comprehensive lifestyle change to maintain disease stability. When patients with HF are married, the spouse frequently assumes the caregiving role. Our objectives were to describe the health of spouses of married patients with HF, and examine whether the health of a spouse impacts patient outcomes. METHODS AND RESULTS: We identified 905 patients that were married at the time of incident HF diagnosis in Olmsted County, MN, from 2000 to 2012...

BACKGROUND: Alterations in autophagy have been reported in hypertrophic cardiomyopathy (HCM) caused by Danon disease, Vici syndrome, or LEOPARD syndrome, but not in HCM caused by mutations in genes encoding sarcomeric proteins, which account for most of HCM cases. MYBPC3, encoding cMyBP-C (cardiac myosin-binding protein C), is the most frequently mutated HCM gene. METHODS AND RESULTS: We evaluated autophagy in patients with HCM carrying MYBPC3 mutations and in a Mybpc3-targeted knockin HCM mouse model, as well as the effect of autophagy modulators on the development of cardiomyopathy in knockin mice...

BACKGROUND: To investigate preimplant risk factors associated with early right ventricular assist device (RVAD) use in patients undergoing continuous-flow left ventricular assist device (LVAD) surgery. METHODS AND RESULTS: Patients in the Interagency Registry for Mechanically Assisted Circulatory Support who underwent primary continuous-flow-LVAD surgery were examined for concurrent or subsequent RVAD implantation within 14 days of LVAD. Risk factors for RVAD implantation and the combined end point of RVAD or death within 14 days of LVAD were assessed with stepwise logistic regression...

BACKGROUND: Patients with heart failure (HF) and atrial fibrillation (AF) have higher circulating levels of NT-proBNP (N-terminal pro-B-type natriuretic peptide) than HF patients without AF. There is uncertainty about the prognostic importance of a given concentration of NT-proBNP in HF patients with and without AF. We investigated this question in a large cohort of patients with HF and reduced ejection fraction. METHODS AND RESULTS: We studied 14 737 patients with HF and reduced ejection fraction and a measurement of NT-proBNP at time of screening, enrolled in either the PARADIGM-HF trial (Prospective Comparison of ARNI With ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) or the ATMOSPHERE trial (Aliskiren Trial to Minimize Outcomes in Patients With Heart Failure), of whom 3575 (24%) had AF on their baseline ECG...
