Association Between Silent Myocardial Ischemia And Duration Of Diabetes Among Diabetics

Background: Today's global health issue is diabetes which is either due to insulin insufficiency or decrease insulin utilization by body. Cardiovascular event usually associated with diabetes is usually silent myocardial ischemia.Aim: To determine the association between cardiovascular event (silent MI)with duration of diabetes.Methodology: Current survey held at Mayo Hospital, Lahore, from January-June 2011. In this study, patients enrolled (325) having both genders with age (35-65years). All Patients were considered for Exercise Tolerance test ( ETT) after ruling out any symptom regarding myocardial ischemia. Collected data was analyzed by SPSS version 17. Mean +/- SD was given for duration of diabetes. Percentage was given for gender and silent MI among subjects enrolled. Chi square test applied post stratification with p value >= 0.05 was considered significant.Results: Mean age of the patients was 49.92 +/- 5.55 years. Males (60.3%) whereas females were (39.7%) enrolled. Mean duration of diabetes in enrolled subjects turned out to be 10.04 +/- 4.61 years. Among 325 patients, 58% patients had silent myocardial ischemia with duration of diabetes above 10years.Conclusion: We concluded that risk of cardiovascular event (silent MI) increases with increase in duration (years) of diabetes.
