Pathophysiology UT TYLER – Questions With Complete Solutions congestive heart failure (CHF) ✔️Ans - Clinical condition resulting from a weakened ventricular muscle causing inability to pump enough blood to systemic circulation to meet the demands of tissue Cause of left ventricular failure (LVF) ✔️Ans - Hypertension Myocardial ischemia Valvular disease (mitral regurgitation, aortic valve stenosis) Cause of right ventricular failure (RVF) ✔️Ans - Chronic pulmonary disease Valvular disease Pump failure major effects ✔️Ans - Decreased cardiac output Back up congestion Hypertrophy of ventricle Decreased stroke volume congestive heart failure (CHF) risk factors ✔️Ans - Age Ethnicity Family history Diabetes Obesity Lifestyle factors Medications Cocaine abuse Sleep apnea Congestive heart defects Viruses Alcohol abuse Kidney conditions Pathological changes that lead to congestive heart failure (CHF) ✔️Ans - All lead to a reduction in cardiac output (CO) Fluid overload - increases pre-load Impaired ventricular filling - impairs stretch
