Increased pulmonary venous pressure secondary to left heart disease is the most common cause of pulmonary hypertension (PH). The diagnosis of PH due to left heart disease relies on a clinical probability assessment followed by the invasive measurements of a mean pulmonary artery pressure (PAP) ≥25 mm Hg and mean wedged PAP (PAWP) >15 mm Hg. A combination of mean PAP and mean PAWP defines postcapillary PH. Postcapillary PH is generally associated with a diastolic pulmonary pressure gradient (diastolic PAP minus mean PAWP) <7 mm Hg, a transpulmonary pressure gradient (mean PAP minus mean PAWP) <12 mm Hg, and pulmonary vascular resistance ≤3 Wood units (WU)...

BACKGROUND: The diastolic pressure difference (DPD) is recommended to differentiate between isolated postcapillary and combined pre-/postcapillary pulmonary hypertension (Cpc-PH) in left heart disease (PH-LHD). However, in usual practice, negative DPD values are commonly calculated, potentially related to the use of mean pulmonary artery wedge pressure (PAWP). We used the ECG to gate late-diastolic PAWP measurements. We examined the method's impact on calculated DPD, PH-LHD subclassification, hemodynamic profiles, and mortality...

BACKGROUND: Skeletal muscle mass decreases in end-stage heart failure and is predictive of clinical outcomes in several disease states. Skeletal muscle attenuation and quantity as quantified on preoperative chest computed tomographic scans may be predictive of mortality after continuous flow (CF) left ventricular assist device (LVAD) implantation. METHODS AND RESULTS: A single-center continuous flow-LVAD database (n=354) was used to identify patients with chest computed tomographies performed in the 3 months before LVAD implantation (n=143)...

BACKGROUND: A cohort of heart failure (HF) patients receiving left ventricular assist devices (LVADs) has decoupling of their diastolic pulmonary artery pressure and pulmonary capillary wedge pressure. However, the clinical implications of this decoupling remain unclear. METHODS AND RESULTS: In this prospective study, patients with LVADs underwent routine invasive hemodynamic ramp testing with right heart catheterization, during which LVAD speeds were adjusted. Inappropriate decoupling was defined as a >5 mm Hg difference between diastolic pulmonary artery pressure and pulmonary capillary wedge pressure...

BACKGROUND: The cytoplasmatic pattern recognition receptor, NOD2 (nucleotide-binding oligomerization domain 2), belongs to the innate immune system and is among others responsible for the recognition of single-stranded RNA. With Coxsackievirus B3 (CVB3) being a single-stranded RNA virus, and the recent evidence that the NOD2 target, NLRP3 (NOD-like receptor family, pyrin domain containing 3) is of importance in the pathogenesis of CVB3-induced myocarditis, we aimed to unravel the role of NOD2 in CVB3-induced myocarditis...

BACKGROUND: The sinus node inhibitor ivabradine was approved for patients with heart failure (HF) after the ivabradine and outcomes in chronic HF (SHIFT [Systolic Heart Failure Treatment With the IF Inhibitor Ivabradine Trial]) trial. Our objective was to characterize the proportion of patients with HF eligible for ivabradine and the representativeness of the SHIFT trial enrollees compared with those in the Swedish Heart Failure Registry. METHODS AND RESULTS: We examined 26 404 patients with clinical HF from the Swedish Heart Failure Registry and divided them into SHIFT type (left ventricular ejection fraction <40%, New York Heart Association class II-IV, sinus rhythm, and heart rate ≥70 beats per minute) and non-SHIFT type...

BACKGROUND: The association between dipeptidyl-peptidase IV inhibitors (DPP-4i) and heart failure (HF) remains unclear. In 1 randomized controlled trial and some observational studies, DPP-4i reportedly increased the risk of HF, but 2 other randomized controlled trials and observational studies have shown no such risk. Here, we evaluated the risk of HF and cardiovascular outcomes of DPP-4i compared with sulfonylureas. METHODS AND RESULTS: A population-based retrospective cohort study was conducted using the Korean Health Insurance Review and Assessment Service database from January 1, 2009, to December 31, 2015...

BACKGROUND: Prevalence of heart failure (HF) increases significantly with age, coinciding with age-related changes in body composition that are common and consequential. Still, body composition is rarely factored in routine HF care. METHODS AND RESULTS: The Health, Aging, and Body Composition study is a prospective cohort study of nondisabled adults. Using yearly dual-energy x-ray absorptiometry, body composition was assessed in the Health, Aging, and Body Composition study over 6 years, comparing those who developed incident HF versus those who did not...

BACKGROUND: In human heart failure, Ser199 (equivalent to Ser200 in mouse) of cTnI (cardiac troponin I) is significantly hyperphosphorylated, and in vitro studies suggest that it enhances myofilament calcium sensitivity and alters calpain-mediated cTnI proteolysis. However, how its hyperphosphorylation affects cardiac function in vivo remains unknown. METHODS AND RESULTS: To address the question, 2 transgenic mouse models were generated: a phospho-mimetic cTnIS200D and a phospho-silenced cTnIS200A, each driven by the cardiomyocyte-specific α-myosin heavy chain promoter...

BACKGROUND: Heart failure (HF) prevalence in arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) varies depending on study cohort and is not well characterized. This study sought to determine prevalence and predictors of HF in ARVC/D. METHODS AND RESULTS: Clinical HF, defined as at least 1 HF sign or symptom, was retrospectively adjudicated for 289 patients meeting ARVC/D Task Force Criteria. HF was present in 142 patients (49%): 113 had isolated RV involvement and 29 had evidence of LV dysfunction...

BACKGROUND: Endogenous regenerative capacity, assessed as circulating progenitor cell (PC) numbers, is an independent predictor of adverse outcomes in patients with cardiovascular disease. However, their predictive role in heart failure (HF) remains controversial. We assessed the relationship between the number of circulating PCs and the pathogenesis and severity of HF and their impact on incident HF events. METHODS AND RESULTS: We recruited 2049 adults of which 651 had HF diagnosis...

BACKGROUND: The association between angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB) doses on outcomes in patients with heart failure (HF) with reduced ejection fraction is uncertain. The objective of this study was to investigate the effect of dose of ACEI and ARBs on outcomes and drug discontinuation in patients with HF with reduced ejection fraction. METHODS AND RESULTS: MEDLINE, Ovid SP, and Embase were searched from the inception of these databases till August 2016...

BACKGROUND: Relaxation characteristics and Ca(2+) homeostasis have not been studied in isolated myocardium from patients with hypertensive heart disease (HHD) and heart failure with preserved ejection fraction (HFpEF). Prolonged myocardial relaxation is believed to play an important role in the pathophysiology of these conditions. In this study, we evaluated relaxation parameters, myocardial calcium (Ca(2+)), and sodium (Na(+)) handling, as well as ion transporter expression and tested the effect of Na(+)-influx inhibitors on relaxation in isolated myocardium from patients with HHD and HFpEF...

BACKGROUND: Patients with heart failure and reduced ejection fraction have impaired health-related quality of life (HRQL) with variable responses to therapies that target mortality and heart failure hospitalizations. In PARADIGM-HF trial (Prospective Comparison of ARNI [Angiotensin Receptor-Neprilysin Inhibitor] With ACEI [Angiotensin-Converting-Enzyme Inhibitor] to Determine Impact on Global Mortality and Morbidity in Heart Failure), sacubitril/valsartan reduced morbidity and mortality compared with enalapril...
