A 79-year-old man attends a cardiology appointment

His past medical history includes hypertension and two previous MIs. His current medications to manage his heart failure include ramipril, amlodipine, atorvastatin, bisoprolol and furosemide. The patient reports he remains breathless on minimal exertion and often wakes up during the night feeling breathless.
