The Study of Acute Myocardial Infarctions Triggers in North-Western Iran

BackgroundMyocardial infarction (MI) is one of the important cardiovascular diseases. A trigger is an external stimulus, potential to create a pathological change leading to a clinical event. In addition to the risk factors of myocardial infarction, MI triggers play critical roles in the incidence of acute MI. Methods and ResultsThis is a cross-sectional study of patients with the first acute myocardial infarction in Seyedoshohada heart center of Urmia, Iran. 254 patients were enrolled in the study within one year of study. After 48h of hospitalization, the patients were provided with the questionnaire to collecting the history of the disease ad triggers. Out of 220 (86.4%) patients with STEMI and 34 (13.6%) patients with NSTEMI, there were significant differences (p <0.05) in AMI triggers with LVEF (0.03), gender (0.027), residency and living area (0.039), occupation (0.002), smoking (0.008), abnormal serum TG levels (0.018) and the season of AMI occurrence (0.013). The mean age for AMI patients was 60.4{+/-}12.97 years old with a mean BMI of 26.65{+/-}4.35 kg/m2. ConclusionIn addition to classic risk factors of myocardial infarction, health care systems must pay more attention to triggers that may induce an acute myocardial infarction in people with predisposing factors especially in the male sex, stressful and hand working jobs, and psychological and mental tension patients.
