Open AccessSarcopenic Obesity and Cardiovascular Disease: An Overlooked but High-Risk Syndrome
Sarcopenic obesity (SO), defined as the coexistence of excess fat mass and reduced skeletal muscle mass and strength, has emerged as an important cardiovascular risk factor, particularly in older adults. This ...

Exercise in Specific Diseases: Heart Failure with Preserved Ejection Fraction
Heart failure (HF) with preserved ejection fraction (HFpEF) is the most rapidly increasing form of HF, occurs primarily in older women, and is associated with high rates of morbidity, mortality, and health car...

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...

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...

Physical function and exercise training in older patients with heart failure
Older patients (aged ≥70 years) with heart failure (HF) have substantially impaired physical function and poor clinical outcomes

Article
Management of Heart Failure with Preserved Ejection Fraction: Current Challenges and Future Directions
Heart failure (HF) with preserved ejection fraction (HFpEF) is the most common form of HF in patients older than 65 years. Among elderly women living in the community, HFpEF comprises nearly 90% of incident HF...

Article
Sarcopenic Obesity and the Pathogenesis of Exercise Intolerance in Heart Failure with Preserved Ejection Fraction
Heart failure with preserved ejection fraction (HFpEF) is the most common form of heart failure (HF) in older adults. The primary chronic symptom in patients with HFpEF, even when well compensated, is severe e...

Update on Heart Failure with Preserved Ejection Fraction
Heart failure with preserved ejection fraction (HFPEF) is the most common form of heart failure (HF) in older adults, and is increasing in prevalence as the population ages. Morbidity and long-term mortality i...

Frailty and multiple comorbidities in the elderly patient with heart failure: implications for management
Heart failure (HF) in the elderly is a major public health problem, and its prevalence is rising. Outcomes of HF in the elderly have not changed in the past 2 decades despite the introduction of novel HF thera...

Open AccessReduced peripheral arterial blood flow with preserved cardiac output during submaximal bicycle exercise in elderly heart failure
Older heart failure (HF) patients exhibit exercise intolerance during activities of daily living. We hypothesized that reduced lower extremity blood flow (LBF) due to reduced forward cardiac output would contr...

Open AccessAdverse effect of increased left ventricular wall thickness on five year outcomes of patients with negative dobutamine stress
To determine if patients without dobutamine induced left ventricular wall motion abnormalities (WMA) but an increased LV end-diastolic wall thickness (EDWT) exhibit a favorable cardiac prognosis.

Exercise Intolerance in Patients with Heart Failure: Role of Diastolic Dysfunction
Most patients with severe left ventricular dysfunction have exercise intolerance. Maximal oxygen consumption during a standardized exercise protocol is an objective measure of exercise tolerance. Since oxygen ...
