Article
Open AccessIncreased skeletal intermuscular fat is associated with reduced exercise capacity in cancer survivors: a cross-sectional study
Cancer survivors experience on average a 20% reduction in peak exercise capacity (VO2 peak) post-cancer treatment. Intermuscular fat (IMF) is a strong predictor of reduced exercise capacity in heart failure (HF) ...

Preventing Heart Failure by Treating Systolic Hypertension: What Does the SPRINT Add?
Previous trials definitively established that lowering systolic blood pressure (BP) to 140 mmHg prevented heart failure (HF) exacerbations, but the potential benefits and risks of further BP reduction remain u...

Article
Open AccessAsymptomatic myocardial ischemia forecasts adverse events in cardiovascular magnetic resonance dobutamine stress testing of high-risk middle-aged and elderly individuals
Current guidelines for assessing the risk of experiencing a hospitalized cardiovascular (CV) event discourage stress testing of asymptomatic individuals; however, these recommendations are based on evidence ga...

Therapy for heart failure with preserved ejection fraction: current status, unique challenges, and future directions
Heart failure (HF) with preserved ejection fraction (HFpEF) is the most common form of HF. Among elderly women, HFpEF comprises more than 80% of incident HF cases. Adverse outcomes—exercise intolerance, poor q...
