ABSTRACT
Population-based data on myocardial infarction rates in the Islamic Republic of Iran have not been reported on a national or provincial scale. In a cross-sectional study, data were collected on 20 750 new cases of myocardial infarction [ICD10 codes I21-22] admitted to hospitals and registered by the Iranian Myocardial Infarction Registry in 2012. The crude and age-adjusted incidence for the 31 provinces and the whole country were directly calculated per 100 000 people using the WHO standard population. Overall, males comprised 72.4% of cases and had a significantly lower mean age at incidence than women [59.6 [SD 13.3] years versus 65.4 [SD 12.6] years]. The male: female incidence ratio was 2.63. The age-standardized myocardial infarction incidence rate was 73.3 per 100 000 in the whole country [95% CI: 72.3%-74.3%] and varied significantly from 24.5 to 152.5 per 100 000 across the 31 provinces. The study provides baseline data for monitoring and managing cardiovascular diseases in the country

Introduction: Data shows that no study at a national level on fatality rates of myocardial infarction [MI] and its determinants in diabetic and non-diabetic hospitalized Iranian patients, has yet been published. The aim of this study was to determine the case fatality rate [CFR] of MI in patients with and without history of diabetes and the factors associated with MI mortality in Iran
Materials and Methods: In this cross-sectional, national study, data of 20,750 new patients with MI were used. For data analysis, Chi-square test, t-test and logistic regression model in Stata software were used. Modeling was done per gender
Results: Of 20,750 new patients with MI, 4,612 [22.3%] patients had diabetes. Case Fatality rates of MI were 13.22% [confidence interval [CI] 95%=12.27-14.23] in diabetic patients and 11.7% [11.28-12.26] in non-diabetic patients, and were significant [p=0.036]. Odds ratio [OR] of mortality from ST segment elevation myocardial infarction STEMI was 4.77 [CI 95%=4.20-5.43] in men, approximately twice that in women [OR=2.13, CI 95%=1.78-2.54]
Conclusion: Although CFR was higher in diabetic patients than in non diabetic ones, the statistically significant difference was not clinically noteworthy, due to the small difference in CFR between the two groups and large sample size of the study. Therefore, prompt management and provision of required healthcare in emergency and CCUs within the appropriate time and access to specialized treatments for diabetic and non diabetic patients are recommended
ABSTRACT
Smoking is one of the main reversible risk factors for coronary artery disease. Incidence of arrhythmia induced by myocardial infarction is the most important reason for death in these patients. Mortality rate in smoking myocardial infarction patients is grater than non smoking patients, but the aim of this study was to compare the incidence of arrhythmias between smoking and non smoking myocardial infarction patients. In this case and control descriptive analytic study, 200 myocardial infarction patients [100 smoking and 100 non-smoking patients] who were referred to cardiac care unite in Hajar university hospital were selected. Data were collected using questionnaires, filing the form of physiological variables, laboratory findings and finally types of arrhythmias and myocardial infarctions. Data were analyzed by the independent-t test and the Fisher's exact test. The average age in smoking patients was 54.23 +/- 8.12 and it was 55.23 +/- 8.11 in non-smoking patients. Type of myocardial infarctions in 70.5% of the cases was anterior myocardial infarction and the rest was inferior myocardial infarction. Our study showed that the type of arrhythmia in smoking group was different than non-smoking group. Sinus tachycardia, Atrial Flutter, preventricular heart beat, ventricular tachycardia and ventricular fibrillation were higher in smoking group compared to the non-smoking group [P < 0.05].According to this study, the incidence of arrhythmia in smoking patients with myocardial infarction is greater than non-smoking patients. Therefore, more attention should be focused on smoking patients with myocardial infarction for arrhythmia
