There are several prognostic risk scores available for patients with heart failure with reduced ejection fraction (HFrEF) that can aid in the decision of listing candidates for heart transplant (HTx). A direct comparison between these scores has not been performed. Therefore, our objective was to evaluate the calibration and discriminative power of 4 contemporary HF scores. A retrospective analysis of 259 patients with HFrEF who underwent cardiopulmonary exercise test was conducted. The Heart Failure Survival Score (HFSS), Seattle Heart Failure Model (SHFM), Meta-analysis Global Group in Chronic Heart Failure (MAGGIC), and Metabolic Exercise Cardiac Kidney Index (MECKI) were compared...

BACKGROUND: The overexpression of human epidermal growth factor receptor-2 (HER2) in breast cancer is a poor prognosis. Trastuzumab improves overall survival but is associated with cardiotoxicity, especially a decline in left ventricular ejection fraction (LVEF). In addition, chemotherapy and radiotherapy increase fatigue and pain, decrease physical capacity and health-related quality of life. To date, no study has evaluated the benefits of physical activity on the side effects of treatment in patients with HER2 positive breast cancer...

BACKGROUND: Systolic left ventricular function strongly influences the blood pressure waveform. Therefore, pressure-derived parameters might potentially be used as non-invasive, diagnostic markers of left ventricular impairment. The aim of this study was to investigate the performance of pressure-based parameters in combination with electrocardiography (ECG) for the detection of left ventricular systolic dysfunction defined as severely reduced ejection fraction (EF). METHODS AND RESULTS: Two populations, each comprising patients with reduced EF and pressure-matched controls, were included for the main analysis (51/102 patients) and model testing (44/88 patients)...

Heart rate (HR) is associated with cardiovascular outcomes in all the stages of the cardiovascular continuum as well as in patients with pulmonary, cerebrovascular, and renal disease, sepsis, cancer, and erectile dysfunction. In patients with cardiovascular disease, but also in the general population, increased HR represents an important indicator of mortality with each acceleration of HR over 70 b.p.m. increasing the risk. In patients in sinus rhythm with chronic heart failure with reduced ejection fraction (HFrEF), a HR >70 b...

Heart failure (HF) with reduced ejection fraction (HFrEF) is a common and costly condition that diminishes patients' health status and confers a poor prognosis. Despite the availability of multiple guideline-recommended pharmacologic and cardiac device therapies for patients with chronic HFrEF, outcomes remain suboptimal. Currently, there is limited insight into the rationale underlying clinical decisions by health care providers and patient factors that guide the use and intensity of outpatient HF treatments...

MitraClip is an approved therapy for mitral regurgitation (MR); however, health care resource utilization pre- and post-MitraClip remains understudied. METHODS: Patients with functional and degenerative MR at high surgical risk in the EVEREST II High-Risk Registry and REALISM Continued-Access Study were linked to Medicare data. Pre- and post-MitraClip all-cause death, stroke, myocardial infarction, heart failure (HF), and bleeding hospitalizations were identified. Inpatient costs, adjusted to 2010 US dollars, were calculated, and event rate ratios and cost ratios were estimated with multivariable modeling...

Chronic heart failure is characterized by autonomic imbalance, cardiac dysfunction and arrhythmogenesis. It has been shown that exercise training (ExT) improves central nervous system oxidative stress, autonomic control and cardiac function in heart failure with reduced ejection fraction (HFrEF), however to date no comprehensive studies have addressed the effects of ExT, if any, on oxidative stress in brainstem cardiovascular areas, cardiac autonomic balance, arrhythmogenesis and cardiac function in heart failure with preserved ejection fraction (HFpEF)...

BACKGROUND: Following pressure overload, compensatory concentric left ventricular remodeling (CR) variably transitions to eccentric remodeling (ER) and systolic dysfunction. Mechanisms responsible for this transition are incompletely understood. Here we leverage phenotypic variability in pressure overload-induced cardiac remodeling to test the hypothesis that altered mitochondrial homeostasis and calcium handling occur early in the transition from CR to ER, before overt systolic dysfunction...

BACKGROUND: The presence of good coronary collateral circulation (CCC) can protect and preserve myocardium from ischemia, increase myocardial contractility, and reduce adverse clinical events. However, its impact on mortality is still a topic of debate, particularly in acute coronary syndrome (ACS). The aim of this study was to investigate the association of CCC with cardiac risk factors and in-hospital mortality in patients hospitalized with a diagnosis of ACS. METHODS: The study population included 2286 patients with ACS who underwent coronary angiography and were found to have at least 90% significant lesion in at least one major coronary artery...

Hydrogen sulfide (H2S) has been recognized as an important gasotransmitter exerting various physiological effects, especially in the cardiovascular system. Herein we investigated the cardioprotective effects of a novel long-term and slow-releasing H2S donor, DATS-MSN, using in vivo myocardial ischemia/reperfusion (I/R) models and in vitro hypoxia/reoxygenation cardiomyocyte models. Unlike the instant-releasing pattern of sodium hydrosulphide (NaHS), the release of H2S from DATS-MSN was quite slow and continuous both in the cell culture medium and in rat plasma (elevated H2S concentrations during 24 h and 72 h reperfusion)...

BACKGROUND: The pathogenic role of ischemic heart disease (IHD) in heart failure (HF) with reduced ejection fraction (HFrEF; EF <40%) is well established, but its pathogenic and prognostic significance in HF with midrange (HFmrEF; EF 40%-50%) and preserved EF (HFpEF; EF ≥50%) has been much less explored. METHODS AND RESULTS: We evaluated 42 987 patients from the Swedish Heart Failure Registry with respect to baseline IHD, outcomes (IHD, HF, cardiovascular events, and all-cause death), and EF change during a median follow-up of 2...
