Incidence of acute myocardial infarction in Islamic Republic of Iran: a study using national registry data in 2012

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

Coronary heart disease and associated risk factors in Qazvin: a population-based study

In a cross-sectional study in Qazvin, Islamic Republic of Iran, 846 residents [425 men and 421 women] aged >/= 25 years were assessed for coronary heart disease and its associated risk factors comparing ischaemic and non-ischaemic groups. The age-adjusted prevalence of possible myocardial infarction, ischaemic ECG changes and angina pectoris were 4.2%, 36.8% and 2.2% respectively. There was no difference in the mean systolic and diastolic blood pressure and body mass index between ischaemic and non-ischaemic groups. There was a significant association between possible myocardial infarction and hypertension, type 2 diabetes, and smoking in women. There was also a significant association between ischaemic ECG changes and waist'hip ratio in women and between ischaemic ECG changes and hypertension in men

relationship between ischemic heart disease and coronary risk factors in population aged over 25 in Qazvin: a population-based study

Coronary heart disease [CHD] is the first and the most common cause of death in all age groups and both sexes in Iran. To determine the CHD prevalence among the population of Qazvin. In this cross sectional study, 501 males and 499 females aged 25 or more [mean 47.1 +/- 11.9 yr] were assessed for the presence of CHD. Twelve lead ECG was obtained for each participant over 30 years old. The CHD risk factors were compared between normal and ischemic groups. The Minnesota code was used for ECG coding. Age adjusted prevalence of possible MI, ischemic ECG and angina pectoris were 2.5%, 18.9%, and 1.1%, respectively. There was no significant difference between mean values of systolic/diastolic blood pressure among ischemic ECG and possible MI groups when compared with normal group. Also, the comparison of mean values for BMI in ischemic ECG and possible MI groups with normal group shown to be insignificant, statistically. There was a significant association between possible MI and hypertension, type II diabetes, and smoking in females. The data were also indicative of a significant relationship between the ischemic ECG and WHR in females and hypertension in males. Meanwhile, the possible MI was more frequent in smokers than non smokers. Based on results obtained in our study, CHD was directly associated with age and smoking in all sex and age groups and also with hypertension and diabetes in females. So, regarding the high prevalence of asymptomatic CHD, the screening and preventive measures for CHD risk factors seem to be necessary
