Abstract
Age, sex, hyperlipidemia, hypertension (HT), smoking, diabetes (DB) and familial causes are considered as the major risk factors of ischemic heart disease (IHD). High levels of plasma homocysteine (Hcy) might be a main involvement in cardiovascular disorders, but lowering the plasma levels of Hcy has not been found as the cure for the cardiac diseases. In view of the controversies related to role of Hcy in IHD it was planned to conduct a study to investigate a precise role of Hcy in IHD patients with various risk factors. The patients were selected after thorough clinical history assessments. They were categorized according to their age and the risk factors they had. The age-matched controls were selected from healthy volunteers. Results for smoking data showed no significant Hcy variations while compared with normal (N) controls. The data of the patients showing the risk factor of hypercholesterolemia (HC) showed significant elevation of Hcy levels for age ranges 70. Whereas N vs DM showed significant variation for age range
