Study some biochemical parameters in patients with Coronary artery disease with and without Type 2 diabetes
Abstract
Background: Impaired lipid metabolism are well recognized factors for Coronary artery disease (CAD) which is the major reason of mortality and morbidity all over world. The incident of CAD with type 2 diabetes mellitus (T2DM) is growing. Aim: The current study aimed to study some biochemical variables (vitamin D3, lipid profile, Insulin, FBG and HbA1C) in patients with diabetes and coronary heart disease and compare them with healthy people. Subjects and Methods: The study was conducted in human beings (apparently healthy and patients). It is statistically considered as [case- control study], the voluntaries were divided as following: 40 apparently healthy persons (40 male) were recruited through advertisement among laboratories and hospital staff in the three medical centers previously mentioned and from friends in Baghdad. 40 voluntaries patients with T2DM were taken, of them (40 male) were recruited from the specialized center for endocrinology and diabetes. 55 voluntaries patients who had CAD (55 male), 55 patients who have had T2DM with CAD (55 male). Results: the results evaluating the BMI of participant revealed that 16.3% had normal BMI, 55.8% were overweight and 27.9% were obese. 65.3% had vitamin D. insufficiency and 16.8% had vitamin D deficiency. The glycemic control evaluation shows that 37.4% had good glycemic control and 16.8% had poor control and 45.8% had excellent control. All participant had insulin resistance in which 31.6% had early resistance. Otherwise, a statistical significant difference in mean level of BMI, vitamin D, insulin level, HOMA-IR, FBS and HbA1c between the 4 groups. For lipid profile, Control group participant had significant lower total cholesterol level in compare to the other groups. Control group participant had significant lower TG level in compare to the other groups. Control group participant had significant higher HDL in compare in CAD group and CAD with DM group. Control group participant had significant lower LDL in compare in CAD group and CAD with DM group. Conclusions: Based on the results of the current study, it was found that there is a strong association between low vitamin D and cardiovascular disease, and it was also found that insulin resistance, which mainly causes type 2 diabetes, has increased health problems in CAD patients. On the other hand, the current study demonstrated that high levels of LDL and cholesterol were closely associated with events and increased risk of CAD.
