Left-Sided Heart Failure
Left-sided heart failure typically presents with pulmonary congestion (dyspnea, orthopnea) and is often caused by ischemic heart disease (IHD) or hypertension, leading to "heart failure cells" in the lungs.
Left-Sided Heart Failure
- Causes: IHD (MI), hypertension, aortic/mitral valve disease, dilated cardiomyopathy
- Left ventricle fails → reduced cardiac output → blood backs up into pulmonary circulation
- Increased pulmonary venous pressure → pulmonary edema
- Reduced perfusion → compensatory mechanisms: sympathetic activation, RAAS activation, ADH
- Pulmonary congestion and edema

Left-Sided Heart Failure
- Causes: IHD, hypertension, mitral/aortic valve disease, cardiomyopathy
- Dyspnea on exertion (earliest symptom)
- Orthopnea → paroxysmal nocturnal dyspnea
- Cardiomegaly, tachycardia, S3 heart sound
- Mitral regurgitation (papillary muscle displacement) → systolic murmur

- Causes: Left-sided heart failure (most common cause), cor pulmonale (COPD, pulmonary hypertension), tricuspid/pulmonary valve disease, RV infarction (CARDIOVASCULAR PATHOLOGY)

- Left-sided heart failure primarily affects the lungs, causing dyspnea and pulmonary edema, while right-sided heart failure leads to systemic venous congestion, manifesting as peripheral edema and hepatosplenomegaly. (Heart Disease — Must Knows)
- Left-sided Heart Failure: Causes include IHD, hypertension; features include dyspnea, orthopnea, S3 heart sound, pulmonary edema, and "heart failure cells" in the lungs. (Heart Disease — Must Knows)
