An important motive for preventive paediatric cardiology is the fact that vascular atherosclerotic lesions may develop in early life. A high risk strategy has been advocated to identify children with hypercholesterolaemia both in the United States (US National Cholesterol Education Program for Children and Adolescents, NCEP-Peds) and European countries including Sweden. The major indicators for lipoprotein screening are a family history of premature CAD and/or a parental serum cholesterol concentration 6.20 mmol/l or greater. A major problem is that the parents are usually quite young and that many children live in one parent households. With coronary artery disease, plaque first grows within the walls of the coronary arteries until the blood flow to the heart’s muscle is limited. View an illustration of coronary arteries. This is also called ischemia. It may be chronic, narrowing of the coronary artery over time and limiting of the blood supply to part of the muscle. Or it can be acute, resulting from a sudden rupture of a plaque and formation of a thrombus or blood clot. The traditional risk factors for coronary artery disease are high LDL cholesterol, low HDL cholesterol, high blood pressure, family history, diabetes, smoking, being post-menopausal for women and being older than 45 for men, according to Fisher. Obesity may also be a risk factor. In this work we compared hypolipidemic effects of Niacin with Cardamom. Seventy five hyperlipidemic patients were selected for research work. They were divided in three groups. Group-I was on placebo, group-II was given 1.5 grams Niacin, and group-III was advised to use powdered Cardamom thrice daily for the period of two months. Their lipid profile was measured at start of research and then on day-60. After two months therapy group-II reduced total cholesterol 30.8 mg/dl and LDL cholesterol 12.1 mg/dl and increased HDL cholesterol 5.6 mg/dl. In group-III Cardamom decreased total cholesterol 7.2 mg/dl and LDL cholesterol 8.8 mg/dl. HDL cholesterol in this group increased 4.9 mg/dl. When results were compiled and analyzed biostatistically, these changes were significant. We conclude from the research work that Niacin has more effects on total cholesterol but effects of both drugs on LDL cholesterol reduction was almost same.
