Chronic and prolong use of oral contraceptives (OCs) may lead to appearance of undesirable effects in women who used these drugs. There are many types of contraceptives, some contain estrogen and the other contain progesterone, or combination of them in the same drug. This work was performed in a population of adult females to study the relationship between the chronic use of OCs with dyslipidemia and the threat of cardiac diseases. A total 163 volunteers were participated in this study, and, their aged between 21-42 years old. In addition, all women were free of heart disease, dyslipidemia and any hormonal disturbance according to their health records. They were categorized into three differnt groups, the control group included 52 unmarried women and does not use any OCs, group A: included 57 women took OCs (combination pill estrogen and progestin) for less than 6 months, and group B contained 54 women used OCs for more than one year. We meassued lipid profile, and blood indices of cardiovascular disease, like Creatine Kinase-MB (CK-MB), insulin, Lactate Dehydrogenase (LDH) albumin, leptin and HbA1c test. In addition, we determined the coronary risk index, atherogenic Coefficient, and an atherogenic index . Our results recorded a significant increase in total cholesterol, LDL, coronary risk index (TC/HDL), LDH and HbA1c in group2 compared to compared to control group. Furthermore, our data demonstrated no clear differences in Triglyceride, leptin hormone, TG, HDL, insulin, albumin and CK-MB in group2 compared to control. Moreover, the data indicated a significant elevation in the concentration of leptin hormone, LDH, HbA1c, TC, TG, LDL, coronary risk index , atherogenic Coefficient and Atherogenic index, and significant decline in HDL and albumin in group B compared with control group. Therefore, we concluded that oral contraceptive could deter the lipid profile status and some enzyme related to the cardiovascular system. These alterations convey a possible risk for the development of cardiac diseases. Routine screeing of lipid tests would be measured in women used OCs for long periods to avoid any potential risk of cardiac diseases.
