The aim of the present study is to evaluate differential lactate removal kinetics in heart failure patients that are trained according to 2 different exercise protocols: (A) High intensi...
In both ageing and heart failure progressive exercise intolerance is observed. The Leipzig Exercise Intervention in Chronic heart failure and Aging (LEICA) study aims to investigate how ae...
The purpose of this research study is to better understand how skeletal muscle is affected by heart failure, and to determine how exercise interventions impact skeletal muscle and function...
The present study will analyze and compare the chronic effects of two different protocols of aerobic exercise in subjects with heart failure on telomere length.
Patients with chronic heart failure (CHF) underwent to a hospital-based cardiac rehabilitation (CR) program in the Lisbon district Hospitals will be recruited. The participants will be ran...
The role of exercise training modality to attenuate left ventricular (LV) remodeling in heart failure patients with reduced ejection fraction (HFrEF) remains uncertain. The authors performed a systema...
This study sought to discern which central (e.g., heart rate, stroke volume [SV], filling pressure) and peripheral factors (e.g., oxygen use by skeletal muscle, body mass index [BMI]) during exercise ...
Although the enhancement of early-diastolic intra-left ventricular pressure difference (IVPD) during exercise is considered to maintain exercise capacity, little is known about their relationship in h...
Aerobic exercise can delay aging and extend lifespan, but its specific mechanism still remains unclear. One popular theory is that with age and the cell division times increasing, DNA damage will inev...
Iron deficiency is an extremely common co-morbidity in patients with heart failure, affecting up to 50% of all ambulatory patients. It is associated with reduced exercise capacity and physical well-be...
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.
