The long-term association between AF and clinical outcomes, healthcare resource utilization, and healthcare costs among patients with HF remains underexplored. We conducted an exploratory analysis of 5-year outcomes among patients enrolled in the Patient-Centered Care Transitions in HF (PACT-HF) stepped-wedge cluster randomized trial who were hospitalized for HF and discharged alive between February 2015 and March 2016. Patients were stratified by baseline AF status.

Cardiovascular disease (CVD) currently ranks first in global mortality and morbidity and its prevalence increases with age. The most common risk factors for CVD are hypertension, diabetes mellitus, dyslipidaemias, adipositas, smoking, and physical inactivity, Also, depression, anaemia and frailty can be considered important risk factors for CVD. Incidence and prevalence of risk factors and comorbidities increase with age.

Background: Patients with unexplained dyspnea and an elevated mean pulmonary artery pressure (mPAP)/cardiac output (CO) slope on invasive hemodynamic assessment during exercise have worse clinical outcomes. The aim of this study was to evaluate the incremental prognostic value of the noninvasive mPAP/CO slope in addition to heart failure with preserved ejection fraction (HFpEF) probability scores and diastolic stress testing in patients with unexplained dyspnea.

Methods: In a multicenter cohort study involving six Belgian dyspnea clinics, patients with unexplained dyspnea underwent exercise echocardiography for mPAP/CO slope assessment.

Aims: Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome accounting for half of heart failure cases. Although natriuretic peptides are the most accepted and extensively used biomarkers for heart failure, their diagnostic accuracy for HFpEF remains debatable. Here, we aimed to identify a panel of circulating microRNAs (miRNAs) as potential novel biomarkers for diagnosis of HFpEF in a preclinical model, subsequently validated in human HFpEF patients.

Aims: Exercise has been shown to affect the nitric oxide (NO) pathway, which is involved in the pathophysiology of endothelial dysfunction in heart failure (HF) with reduced (HFrEF) and preserved ejection fraction (HFpEF). However, the effects of different exercise modes on NO metabolites in patients with HF are uncertain.

Methods And Results: Blood samples from two randomized controlled HF trials evaluating (i) high-intensity interval training (HIIT), (ii) moderate continuous training (MCT), or (iii) a control group (CG) in HFrEF (SMARTEX-HF) and HFpEF (OptimEx-Clin) were analysed for NO metabolites L-arginine, homoarginine (hArg), asymmetric and symmetric dimethylarginine (ADMA; SDMA).

Background: Cardiac contractility modulation (CCM) is a novel device-based therapeutic option in patients with heart failure with reduced ejection fraction who are not eligible for cardiac resynchronization therapy. Cardiac contractility modulation enhances cardiac contractility by delivering high-voltage non-excitatory electrical impulses during the absolute refractory period. Cardiac contractility modulation is known to improve left ventricular ejection fraction (LVEF), quality of life, and exercise capacity in heart failure (HF) patients.

Atrial functional mitral regurgitation (AFMR) is a distinct form of mitral regurgitation in patients with atrial fibrillation and heart failure with preserved ejection fraction. Its pathophysiology remains elusive, and data on exercise-related AFMR are scarce. We sought to investigate the impact of acute exercise on AFMR severity and to identify its determinants.

Aims: Exercise training (ET) is an effective therapy in heart failure with preserved ejection fraction (HFpEF), but the influence of different ET characteristics is unclear. We aimed to evaluate the associations between ET frequency, duration, intensity [% heart rate reserve (%HRR)] and estimated energy expenditure (EEE) with the change in peak oxygen consumption (V̇O2) over 3 months of moderate continuous training (MCT, 5×/week) or high-intensity interval training (HIIT, 3×/week) in HFpEF.

Methods And Results: ET duration and heart rate (HR) were recorded with a smartphone application.

Article Synopsis
  • Half of the heart failure patients with preserved ejection fraction (HFpEF) remain undiagnosed with just resting evaluations, leading researchers to suggest exercise testing as a potential solution.
  • A study involving 1,936 patients evaluated their exercise performance and the mean pulmonary artery pressure over cardiac output (mPAP/CO) slope to assess their HFpEF likelihood.
  • Results indicated that 22% of patients had abnormal test results with a high mPAP/CO slope despite a negative diastolic stress test (DST), suggesting that this slope could be a key indicator of HFpEF, even when DST results are not conclusive.

Close monitoring for cardiotoxicity during anthracycline chemotherapy is crucial for early diagnosis and therapy guidance. Currently, monitoring relies on cardiac imaging and serial measurement of cardiac biomarkers like cardiac troponin and natriuretic peptides. However, these conventional biomarkers are nonspecific indicators of cardiac damage.

The last decades have illustrated the importance of microRNAs (miRNAs) in various biological and pathological processes. The combined visualization of miRNAs using fluorescent in situ hybridization (FISH) and proteins using immunofluorescence (IF) can reveal their spatiotemporal distribution in relation to the cell and tissue morphology and can provide interesting insights into miRNA-protein interactions. However, standardized protocols for co-localization of miRNAs and proteins are currently lacking, and substantial technical obstacles still need to be addressed.

Aims: Management of patients with atrial fibrillation (AF) and concomitant heart failure (HF) remains complex. The Antwerp score, based on four parameters [QRS >120 ms (2 points), known aetiology (2 points), paroxysmal AF (1 point), severe atrial dilation (1 point)] adequately estimated the probability of left ventricular ejection fraction (LVEF) recovery after AF ablation in a single-centre cohort. The present study aims to externally validate this prediction model in a large European multi-centre cohort.

Increasing evidence links changes in epigenetic systems, such as DNA methylation, histone modification, and non-coding RNA expression, to the occurrence of cardiovascular disease (CVD). These epigenetic modifications can change genetic function under influence of exogenous stimuli and can be transferred to next generations, providing a potential mechanism for inheritance of behavioural intervention effects. The benefits of exercise and nutritional interventions in the primary and secondary prevention of CVD are well established, but the mechanisms are not completely understood.
