Left sided heart Failure Pathophysiology
the most common form of heart failure is left sided. Left sided HF results from left ventricular dysfunction. This prevents normal, forward blood flow and causes blood to back up into the left atrium and pulmonary veins. The increased pulmonary pressure causes fluid leakage from the pulmonary capillary bed into the interstitium and then the alveoli. this manifests as pulmonary congestion and edema.
Right Sided heart failure Pathophysiology
Right sided heart failure occurs when the right ventricle fails to contract effectively. right sided heart failure causes a backup of blood into the right atrium and venous circulation. Venous congestion in the systemic circulation results in jugular venous distention, hepatomegaly, splenomegaly, vascular congestion of the gastrointestinal tract, and peripheral edema. Right sided heart failure may result from an acute condition sich as right ventricle infarction or pulmonary embolism. Cor Pulmonale (right ventricular dilation and hypertrophy caused by pulmonary disease) can also cause right sided HF. Thr primary cause of heart failure is left sided heart failure. In this situation, left sided heart failure results in pulmonary congestionand increased pressure in the blood vessels of the lung (pulmonary hypertension). Eventually, chronic pulmonary hypertension (increased right ventricular afterload) results in right sided hypertrophy and HF.
