MRCP2-0448

A 68-year-old woman presents to the Emergency Department (ED) with retrosternal chest pain that occurred while she was cleaning her kitchen floor. The pain lasted for 30 minutes. She has a history of rheumatic fever and hypertension, but no other significant medical history. The pain started five hours ago and has since resolved. On examination, she is obese with a BMI of 34 kg/m2 and her blood pressure is controlled with ramipril and bendroflumethiazide. An ECG shows broad P waves, but nothing else of note. A CXR reveals evidence of old tuberculosis. What is the recommended management for this patient?
