Abstract

Background

There is a substantial disparity in coronary artery disease (CAD) burden between Iran and other nations that place a strong emphasis on the assessment of CAD risk factors and individuals’ awareness and ability to control them.

Methods

Two thousand participants of a community-based Iranian population aged 20–74 years were investigated with a mean follow-up of 9.9 years (range: 7.6 to 12.2). An analysis of Cox regression was conducted to determine the association between CAD development and classic risk factors such as age, sex, smoking, physical activity, education, obesity, dyslipidemia, hypertension, and diabetes mellitus. Furthermore, we computed the population attributable fraction for these risk factors.

Results

After a follow-up period of nearly 10 years, 225 CAD events were reported, constituting 14.5% of the overall incidence. Nighty three percent of participants had more than one risk factor. Age was the most predictive risk factor, with a hazard ratio (HR) and confidence interval (CI) of 5.56 (3.87–7.97, p < 0.001) in men older than 45 and females older than 55 compared to lower ages. In comparison to females, males had an HR of 1.45 (CI: 1.11–1.90, p value = 0.006) for developing CAD. Nearly 80% of the patients had dyslipidemia, with a hazard ratio of 2.19 (CI: 1.40–3.44, p = 0.01). Among the participants, 28.9% had hypertension, and 52% had prehypertension, which had HRs of 4.1 (2.4–7.2, p < 0.001) and 2.4 (1.4–4.2, p < 0.001), respectively. Diabetes, with a prevalence of 17%, had an HR of 2.63 (CI: 2 -3.47, p < 0.001), but prediabetes was not significantly associated with CAD. Awareness of diabetes, dyslipidemia, and hypertension was 81%, 27.9%, and 48.1%, respectively. Regarding medication usage, the corresponding percentages were 51% for diabetes, 13.2% for dyslipidemia, and 41% for hypertension.

Conclusions

Compared to previous studies in Iran and neighboring countries, the current study found a higher incidence of CAD, more prevalent risk factors, and a lower awareness and ability to control these risk factors. Thus, an effective preventive strategy is needed to reduce the CAD burden in Iran.
