Cardiac output, stroke volume, end-diastolic and end-systolic volumes play vital roles in cardiovascular function. Factors affecting cardiac output include physiological conditions and pathological states like hyperthyroidism and myocardial infarction. Venous return, controlled by mechanisms like Fr

Congestive heart failure (CHF) is a condition characterized by systemic and pulmonary congestion due to the heart's inability to pump sufficient blood for the body's metabolism. It is closely linked to age and involves pathophysiology related to preload, afterload, contractility, and heart rate. Man

In heart failure management, drugs play a crucial role in reducing preload and afterload, increasing cardiac contractility, and improving overall outcomes. Common drug classes include diuretics, aldosterone antagonists, ACE inhibitors, ARBs, beta-blockers, and vasodilators. These medications help al

Congestive heart failure (CHF) is a condition where the heart cannot pump enough blood to meet the body's needs, often caused by conditions like hypertension and coronary artery disease. Factors affecting cardiac output include preload, heart rate, stroke volume, afterload, and contractility. The pa

Heart failure is a serious condition characterized by inadequate cardiac output. Compensatory responses include sympathetic nervous system activation, renin-angiotensin-aldosterone system stimulation, and natriuretic peptide release. Pharmacologic therapies target salt and water retention, afterload
