Congestive Heart Failure - StatPearls - NCBI Bookshelf
2023年11月5日 · Congestive heart failure (CHF) is a complex clinical syndrome characterized by inefficient myocardial performance, resulting in compromised blood supply to the body. CHF results from any disorder that impairs ventricular filling or …
The pathophysiology of heart failure - PubMed
Heart failure results from injury to the myocardium from a variety of causes including ischemic heart disease, hypertension, and diabetes. Less common etiologies include cardiomyopathies, valvular disease, myocarditis, infections, systemic toxins, and cardiotoxic drugs.
Pathophysiology of heart failure - PubMed
Following a cardiac injury (e.g., myocardial infarction, increased preload or afterload) cellular, structural and neurohumoral modulations occur that affect the phenotype being present. These processes influence the cell function among intra- as well as intercellular behavior.
CV Physiology | Pathophysiology of Heart Failure
Cardiac dysfunction precipitates changes in vascular function, blood volume, and neurohumoral status. These changes serve as compensatory mechanisms to help maintain cardiac output (primarily by the Frank-Starling mechanism) and arterial blood pressure (by systemic vasoconstriction).
Pathophysiology of heart failure - Wikipedia
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading.
Mechanisms and Models in Heart Failure | Circulation Research
2021年5月13日 · Despite multiple attempts to develop a unifying hypothesis that explains the pathophysiology of heart failure with a reduced ejection fraction (HFrEF), no single conceptual model has withstood the test of time.
Heart Failure (HF) - Heart Failure (HF) - The Merck Manuals
Cardiac contractility (force and velocity of contraction), ventricular performance, and myocardial oxygen requirements are determined by. Cardiac output (CO) is the product of stroke volume and heart rate; it is also affected by venous return, peripheral …
