Yоu аre seeing а 68-yeаr-оld male with hypertensiоn and non-ischemic cardiomyopathy in clinic today. He has the diagnosis of heart failure with reduced ejection fraction (HFrEF). An echocardiogram one month ago showed left-ventricular hypertrophy and a left-ventricular ejection fraction (LVEF) of 36%. He takes sacubitril/valsartan 97/103 mg (Entresto) BID and carvedilol (COREG) 12. 5 mg PO BID. His pulse is 68 beats/minute, blood pressure is 134/88 mmHg, and oxygen saturation is 95% on RA. His weight is up 8 pounds from his last clinic appointment. His physical exam is notable for jugular venous pulse and pressure (JVP) of 12, bilateral leg edema, and crackles at his lung bases. What will be the next step in management of this man?
