Dr. John H. Alexander

I am a cardiologist trained and experienced in preventive cardiology. I have served as the medical director of the Duke Cardiac Rehabilitation Program (formerly DUPAC) since 1994. I specialize in the prevention and treatment of heart disease risk factors before and after cardiac disease develops. I direct a program that uses the principles of balancing energy intake and expenditure to treat heart disease and metabolic diseases, such as diabetes. I also have an active practice for assessment and advice for the older athlete who wants to improve performance – whether he or she has heart disease or not. My research is directed at defining the best exercise regimen for the most benefit. Dr. Kraus is rated as a Distinguished provider by MediFind in the treatment of Abdominal Obesity Metabolic Syndrome. His top areas of expertise are Coronary Heart Disease, Heart Failure, Metabolic Syndrome, Coronary Artery Bypass Graft (CABG), and Heart Bypass Surgery.

I am passionate about working with individuals to improve their heart health, and to prevent heart disease. I came to medicine after working in developing countries, and seeing just how rampant heart disease is all over the world. I am committed to stopping the rise of heart disease, especially in my patients, because I understand how devastating it can be. My patients and I work together to manage their symptoms and control their risk factors, such as smoking, high blood pressure, high cholesterol, and obesity. In my spare time, I enjoy spending time with my two small children, going for walks with them, reading to them, and cooking (healthy but yummy) meals for them.
