Write answer in between .Q:A 53-year-old white man presents to the emergency department because of progressive fatigue, shortness of breath on exertion, and a sensation of his heart pounding for the past 2 weeks. He has had high blood pressure for 8 years for which he takes hydrochlorothiazide. He denies any history of drug abuse or smoking, but he drinks alcohol socially. His blood pressure is 14555 mm Hg, his radial pulse is 90min and is bounding, and his temperature is 36.5C 97.7F. On physical examination, an early diastolic murmur is audible over the left sternal border. His chest X-ray shows cardiomegaly and echocardiography shows chronic, severe aortic regurgitation. If left untreated, which of the following is the most common long-term complication for this patients condition?? A: Arrhythmias, B: Congestive heart failure, C: Infective endocarditis, D: Sudden death, E: Myocardial ischaemia,  <response>: This is a clinical vignette describing a 53-year-old man with longstanding hypertension who now presents with symptoms and signs of aortic regurgitation, including fatigue, shortness of breath, bounding pulse, early diastolic murmur, and echocardiographic evidence of severe aortic regurgitation. The question asks about the most common long-term complication if this condition is left untreated. Choices include arrhythmias, congestive heart failure, infective endocarditis, sudden death, and myocardial ischemia.In chronic severe aortic regurgitation, the left ventricle must generate increased stroke volume to compensate for the regurgitant volume back into the left ventricle during diastole. Over time, this volume overload leads to left ventricular dilatation, hypertrophy, and eventual systolic dysfunction. Therefore, the most common long-term complication is congestive heart failure due to left ventricular dysfunction.B: Congestive heart failure
