A man who had no known risk factors for heart disease underwent coronary bypass surgery within days after having a heart attack. He did not drink, smoke, was a vegetarian, exercised, did not have diabetes, or hypertension, and only registered a little above the recommended cholesterol value. On further investigation he did have high homocysteine and lipoprotein A levels, proteins which have been identified in recent years to be additional heart disease risk factors. Homocysteine is believed to promote atherosclerosis and thickening of the blood vessels with increased clotting ability of platelets. Lipoprotein A is similar to the 'bad' cholesterol, LDL, and is thought to prevent the breakdown of clots. The blood tests for these two new variables are currently difficult to obtain as they have fairly strict indications. High homocysteine can be avoided by having a healthy diet, high in vitamin B complexes. Lipoprotein levels can be kept low by a healthy diet with niacin and estrogen replacement in postmenopausal women.
