Type II DM, Silent, Myocardial infarction


Objective: To determine the frequency of silent myocardial infraction (SMI) among patients with type II diabetes mellitus.

 Material And Methods Setting: This cross-sectional study was conducted at the Cardiology Department of Liaquat University Hospital in Hyderabad from March 2020 to August 2020. The study included patients diagnosed with type II diabetes mellitus for over 5 years, aged between 40 and 60 years, of both genders, with a respiratory rate more than 20/minute, and confirmed cases of myocardial infarction. Silent myocardial infarction was diagnosed based on established criteria, including ECG changes indicative of myocardial ischemia, imaging evidence of myocardial scar or regional wall motion abnormalities consistent with prior infarction, and the absence of typical symptoms of acute coronary syndrome. All data were entered into SPSS version 16.0 for analysis.

Results: In this study mean of patients was 59.29+12.96 years, mean systolic blood pressure was 134.82+33.57, mean diastolic blood pressure was 82.11+17.98. Males were 54.4% and females were 45.6%. Mean HbA1c level was 11.30+2.90, mean cardiac troponin was 46.0+136.98. However mean duration of diabetes was 11.30+7.46 years. Majority of the patients 61.0% were presented with non-St Elevation MI, while 39.0% were diagnosed as ST elevation MI. Frequency of silent myocardial infarction, 44.1% patients had silent myocardial infarction and 55.9% were without silent myocardial infarction. Frequency of silent myocardial infarction was statistically insignificant according to age, gender, duration of disease, HbA1c and blood pressure, p-values were quite insignificant.

Conclusion: In the conclusion of this study the frequency of silent myocardial infarction was highly prevalent (42.1%) among patients of myocardial infarction with diabetes mellitus type II. However, this prevalence was statistically insignificant according to age, gender, HbA1c, duration of disease and blood pressure
