Coronary artery disease (CAD) is the major cause of mortality worldwide and is defined as an elevated level of atherogenic cholesterol and low levels of HDL cholesterol. However, very few studies have been conducted in India on the association of blood lipid profile with age and diet. The study aims to estimate lipid parameters in the blood of CAD patients aged 40-70 years on different diets. Lipid parameters were analyzed by enzymatic method on EM-200 fully automated Biochemistry analyzer. The data obtained showed that the majority of patients who suffered from CAD were between the age group of 51-60 years. Patients with CAD had altered lipid profiles, with higher levels of serum TGs, total cholesterol and low levels of HDL. Vegetarians have been found to have reduced lipid risk factors for coronary heart disease compared to patients on a mixed diet.

Elevated serum ferritin (SFer) levels have been associated with chronic diseases such as coronary heart disease and diabetes mellitus type 2. The aim of this study was to examine the relationship between SFer levels and serum lipid parameters, and how this relation changes in terms of age and gender. Additionally, we investigated a possible relationship between SFer levels and high-density lipoprotein (HDL) function. SFer levels and lipid panel (total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C) and HDL-C) of 4205 people (3139 women, 1066 men) were examined retrospectively. Study population was classified according to age and gender. Separately, 100 subjects (52 women, 48 men) were randomly recruited to investigate the relation between SFer levels, and HDL dependent paraoxonase-1 (PON1) and arylesterase (ARE) activities. In all age groups, women’s SFer levels were found to be significantly lower and HDL-C levels significantly higher compared to men. In the 50-70 ages range, TC and LDL-C levels of women were found to be significantly higher than those of men (P < 0.01). SFer levels tended to increase with age in women. Correlation analyses revealed a negative correlation between levels of SFer and HDL-C, while positive correlations existed between levels of SFer, and TC, TG and LDL-C. There was no significant correlation between SFer levels and PON1 or ARE activities. The finding that increased SFer levels are accompanied by increased serum TC, TG and LDL-C levels may help us to explain the increased risk of metabolic disorders and cardiovascular disease in postmenopausal women.
