Heart Failure (Left-sided)

Heart Failure (Left-sided) is a condition where the heart's left side cannot pump blood effectively to the rest of the body. This affects the cardiovascular system, leading to a buildup of fluid in the lungs, causing symptoms like shortness of breath and fatigue. The heart muscle may become weak or stiff, reducing its ability to supply oxygen-rich blood. This can make everyday activities difficult and may cause swelling in the legs or abdomen. The condition often results from other heart problems such as high blood pressure or heart attacks.

Heart Failure (Left-sided) is a clinical syndrome characterized by the inability of the left ventricle to maintain adequate cardiac output to meet the body's metabolic demands. It commonly results from systolic dysfunction due to ischemic heart disease or diastolic dysfunction from conditions like hypertension-induced ventricular hypertrophy. The core pathology involves impaired left ventricular contractility or relaxation, leading to increased left atrial pressure and pulmonary congestion. This causes hallmark symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. The condition is significant because it leads to pulmonary edema, decreased exercise tolerance, and increased mortality risk. Diagnosis and management focus on identifying underlying causes and preventing progression.
