A 59-year-old man presents to his internist for a routine visit. He has no complaints, and review of symptoms is negative. His past medical history is significant for poorly controlled hypertension for 15 years due to noncompliance with antihypertensive medications. He takes hydrochlorothiazide 25 mg orally four times a day. His family history is significant for hypertension, heart failure, and stroke. He has a 30-pack-year smoking history and drinks two beers a day. On physical examination he is a mildly obese man in no acute distress. He has a normal jugular venous pressure. He has a prominent point of maximum impulse, regular rate and rhythm, normal S1, loud S2, and audible S4 with no murmurs. His lungs are clear to auscultation bilaterally, and he has no signs of edema. His abdominal and neurologic examinations are within normal limits. His temperature is 37.0°C (98.6°F), pulse is 81/min, respiratory rate is 12/min, blood pressure is 165/96 mm Hg, and oxygen saturation is 100% on room air. His ECG shows normal sinus rhythm with large amplitude of the S wave in V1 and V2 and of the R wave in V5 and V6. Also present are diffuse ST segment/T wave changes, widened bifid P waves, and prolonged QRS waveforms. Which of the following is the most likely diagnosis?
(A) Acute myocardial infarction
(B) Cerebrovascular accident
(C) Dilated cardiomyopathy
(D) Left ventricular hypertrophy
(E) Pericarditis
