Tim goes to his family physician complaining of worsening angina, shortness of breath, and extreme fatigue.

Tim goes to his family physician complaining of worsening angina, shortness of breath, and extreme fatigue. Tim is 5’11”, 240 lbs, and 68 years old. He has a history of smoking (one pack a day for 40 years), and is on the verge of Type II diabetes. Tim has been previously diagnosed with atherosclerosis, and has had bypass surgery to correct 2 blocked coronary arteries. A year ago, Tim had a heart attack and spent a couple of months in the hospital, during which he quit smoking.

Tim is retired, and leads a virtually sedentary lifestyle. He goes for a walk with his wife one or two times a week when she drags him out, but lately he’s been too tired even to do that. He tries to watch what he eats – he avoids sweets most of the time, but still consumes a relatively high fat diet and has at least one beer every evening. He’s a bit concerned about his condition, but apart from the occasional chest pain and fatigue, claims that he feels “just fine”.
