Stenoses within the coronary circulation most commonly occur in people who smoke or who have diabetes mellitus, hypertension, adverse lipid profiles, or a familial predisposition to coronary heart disease. CAD tends to worsen as people age and is more common in men than in women. A person's risk for coronary artery disease can be estimated, e. If blockages within the coronary arteries limit the flow of oxygenated blood to the myocardium, ischemia or infarction of the heart muscle may occur. Typically, patients who experience symptoms due to CAD report pain, burning, or pressure in the chest angina pectoris that begins or worsens with exertion, emotion, exposure to cold air, or the eating of a large meal.
By Stephen T. Sinatra, M. Heart rate variability HRV — the measure of the variation in time between your heart beats — is perhaps the most important biomarker you and your doctor should know. Other, more familiar biomarkers of cardiovascular health — such as cholesterol numbers, blood pressure readings, pulse rate, C-reactive protein — and you probably know your numbers by heart — all give us physicians useful information, but none can conclusively tell us whether you have a normal, healthy ticker.

Working together with your doctor is the best way to find effective treatments that fit your unique needs.
