• He is placed on a low-sodium diet and treated with a diuretic (furosemide 40 mg twice daily) and digoxin 0.25 mg daily. On this therapy, he is less short of breath on exertion and can also lie flat without dyspnea. An angiotensin-converting enzyme (ACE) inhibitor is added (enalapril 20 mg twice daily), and over the next few weeks he continues to feel better. Three months after the first visit, the man is asymptomatic at rest and with mild exercise. Heart rate is 80, and blood pressure is 110/70. A repeat echocardiogram shows that his heart is smaller (though not back to normal) and his left ventricular ejection fraction has improved to 40%.
