There is mild elevation in his jugular venous pulse. There is trace lower-extremity edema. The remaining physical examination is unremarkable. Laboratory testing reveals normal BMP and renal function. An echo performed 9 months ago demonstrates left ventricular ejection fraction of 39%. Which of the following medications should be added to this patient's regimen?
