A 62-year-old man presents with a three month history of increasing breathlessness on exertion

A 62-year-old man presents with a three month history of increasing breathlessness on exertion, associated with a dry cough. He has been feeling very tired and has lost around a stone in weight over the past few months. He has never smoked and is a retired school teacher. His past medical history is significant for hypertension and atrial fibrillation. He reports he takes ramipril for his blood pressure, bisoprolol for his heart, and another medication for his heart – the name of which he cannot recall.
