Cardiac ultrasound in resource-limited settings (CURLS): towards a wider use of basic echo applications in Africa.

Point-of-care ultrasound is increasingly being used as a diagnostic tool in resource-limited settings. The majority of existing ultrasound protocols have been developed and implemented in high-resourc...

Unlocking the Secrets of Mitochondria in the Cardiovascular System: Path to a Cure in Heart Failure—A Report from the 2018 National Heart, Lung, and Blood Institute Workshop

Mitochondria have emerged as a central factor in the pathogenesis and progression of heart failure, and other cardiovascular diseases, as well, but no therapies are available to treat mitochondrial dy...

Targeting pulmonary capillary permeability to reduce lung congestion in heart failure: a randomized, controlled pilot trial.

Lung congestion in patients with heart failure (HF) has traditionally been treated using interventions that reduce pulmonary capillary hydrostatic pressure. The transient receptor potential vanilloid ...

Validation of the Arabic Version of the Minnesota Living with Heart Failure Questionnaire.

The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is commonly used to measure quality of life (QOL) in patients with heart failure (HF). We examined the psychometric properties and cultura...

Medical and Biotech [MESH] Definitions

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.

A condition of lung damage that is characterized by bilateral pulmonary infiltrates (PULMONARY EDEMA) rich in NEUTROPHILS, and in the absence of clinical HEART FAILURE. This can represent a spectrum of pulmonary lesions, endothelial and epithelial, due to numerous factors (physical, chemical, or biological).

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.
