A 62-year-old man with paroxysmal atrial fibrillation (AF) presents to his physician’s office for a discussion of treatment options for his AF. He has no history of hypertension or other stroke risk factors, and echocardiography indicates normal left ventricular function and left atrial size. He is highly symptomatic during his AF episodes despite treatment with β blockers for rate control. He is prescribed amiodarone to maintain sinus rhythm. Should this patient also be prescribed an angiotensin-converting enzyme inhibitor or an angiotensin-receptor blocker to enhance the efficacy of rhythm control?
