Homocysteine as a Risk Factor for Coronary Artery Disease in Pakistan
Pakistani people belong to an ethnic group which has the highest rate of coronary artery disease. There are a number of risk factors for developing the coronary artery disease (CAD). Homocysteine, a sulphur con-taining amino acid, has been reported to be an inde-pendent risk factor for CAD. The present study was done to find out the role of hyperhomocysteinemia in the development of coronary artery disease in Pakis-tan.
Materials and Methods: A cross sectional study was carried out. There were 40 angiographically diagnosed male patients of coronary artery disease between 30 – 40 years of age taken as cases and 40 age, sex and socioeconomically matched healthy subjects with normal carotid doppler study taken as controls. Fasting venous blood from cases and controls was taken in E.D.T.A vacationers. Plasma was analyzed for homo-cysteine level by enzyme immunoassay method.
Results: Mean plasma concentration of homocysteine in coronary artery disease patients i.e. cases was 13.5 ± 6.8 µmol/L and was higher than the mean for con-trols (10.76 ± 2.27 µmol/L) to a significant extent.
Conclusion: Hyperhomocysteinemia through inter-play with the classical cardiovascular risk factors may be aggravating the risk of coronary artery disease in Pakistani people.
