ABSTRACT
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.
Keywords: Myocardial Ischemia, Type 2 Diabetics and Exercise
Tolerance Test.
