Introduction: As a lack of validated data about cardiovascular (CV) events and its risk factors (RFs) in women of Eastern Mediterranean region, we aimed to evaluate common predictors of CV events among Iranian women. Methods: Isfahan cohort study (ICS) is a prospective cohort that followed 6323 residents (51.3% women, aged 35-75 years) from three counties and their rural districts in central Iran. Common cardiovascular disease (CVD) RFs namely hypertension (HTN), diabetes mellitus, dyslipidemia, abdominal obesity, smoking, low apolipoproteins A ( apo-A) and high apolipoprotein B (apo-B) were evaluated. End points (CV events) were defined as fatal and nonfatal myocardial infarction, sudden cardiac death (SCD), unstable angina and stroke. Results: After 9 years of follow-up, 265 CV events were detected. The mean age of women with CV event was 57.6±10.9; about 8 years older than those without event. All CV RFs were significantly more prevalent in women with CV event except for low HDL cholesterol, overweight and low apo-A. HTN, diabetes, high triglyceride (TG), high LDL-C and obesity were significantly associated with CV events after adjustment for age, smoking and menopausal status (hazard ratios [95% CI]: 2.56 [1.93, 3.95], 2.43 [1.76, 3.35], 2.02 [1.49, 2.74], 1.59 [1.20, 2.11] and 1.49 [1.16-1.92], respectively), while low HDL cholesterol and abdominal obesity were not predictors for CV events (hazard ratios [95% CI]: 1.26 [0.96, 1.65], 1.71 [0.99, 2.96], respectively). Conclusion: In ICS, HTN, diabetes mellitus and high triglyceride are strong predictors for CV events in Iranian women. As almost all strong risk markers of CVD events are preventable, health policy makers have to give urgent consideration to make preventive public health strategies.
