Comprehensive Study of Acute Myocardial Infarctions Triggers

Aim: Myocardial infarction (MI) is one of the most important cardiovascular diseases. A trigger is an external stimulus, potential to create a pathological change leading to a clinical event. In addition to classic risk factors of ischemic heart disease and myocardial infarction, MI triggers play critical roles in the incidence of acute MI. Methods and Results: This is a cross-sectional study of 254 patients with the first acute myocardial infarction referring to Seyedoshohada heart center of Urmia, Iran were enrolled in the study within one year of study. After 48h of hospitalization and, treatment, and cardiac caring, the patients were provided with the questionnaire to collecting the history of the disease ad triggers. In addition to laboratory and paraclinical data, the analysis of the study was performed. Out of 220 (86.4%) patients with STEMI and 34 (13.6%) patients with NSTEMI, there were significant differences (P-value <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. Conclusion: In addition to classic risk factors of ischemic heart disease and myocardial infarction, health care systems and physicians 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.
