He does not smoke. His father died suddenly at the age of 49 years. His blood pressure is 138/84 mm Hg. The level of total cholesterol is 261 mg per deciliter, low-density lipoprotein cholesterol 172 mg per deciliter, and high-density lipoprotein cholesterol 50 mg per deciliter, and the triglyceride level is 113 mg per deciliter. An exercise test is positive, with pain and 1.5 mm of horizontal ST-segment depression at stage 4 of the Bruce protocol. How should the patient's case be managed?
