2020年2月28日 · Heart failure is an epidemic disease which affects about 1% to 2% of the population worldwide. Both, the etiology and phenotype of heart failure differ largely. Following a cardiac injury (e.g., myocardial infarction, increased preload or afterload) cellular, structural and neurohumoral modulations occur that affect the phenotype being present.

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 ejection of blood to the systemic circulation. Patients usually present with fatigue and dyspnea, reduced exercise ...
Heart Failure (HF) - Heart Failure (HF) - The Merck Manuals
Heart failure (HF) involves ventricular dysfunction that ultimately leads to the heart not providing tissues with adequate blood for metabolic needs. In heart failure with reduced ejection fraction (HFrEF), the ventricle contracts poorly and empties inadequately; ejection fraction is low.
Pathophysiology of heart failure - PubMed
The understanding of the underlying pathophysiology of heart failure is essential to initiate the adequate therapeutic option individually for each patient. Furthermore, prevention of cardiovascular risk factors is essential to lower the risk of heart failure.
Congestive Heart Failure Pathophysiology - Verywell Health
2024年10月5日 · What Is the Pathophysiology of Heart Failure? Heart failure develops when there are changes to the structure of the heart muscle and it can't pump blood as efficiently as it should. When this happens blood can back up and fluid may build up in the lungs or arms and legs, indicating congestive heart failure.

2000年1月1日 · Heart failure is a multisystem disorder which is characterised by abnormalities of cardiac, skeletal muscle, and renal function; stimulation of the sympathetic nervous system; and a complex pattern of neurohormonal changes.
CV Physiology | Pathophysiology of Heart Failure
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).

2015年12月15日 · This summary of the pathophysiology of heart failure tries to give a compact overview of basic mechanisms and of the novel unfolding, progressive theory of heart failure to contribute to a more comprehensive knowledge of the disease.
Congestive Heart Failure: Pathophysiology, Diagnosis, and …
The 10 chapters on pathophysiology, including those on renal salt and water handling, the peripheral circulation, and the role of the pericardium, are all superbly written, illustrated, and referenced. Eight chapters are dedicated to the differential diagnosis of congestive heart failure, including cardiomyopathies, valvular heart disease, and ...
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.
