Coronary artery disease in Iranian overweight women
Introduction
In Iran, coronary artery disease is the first cause of mortality and it accounts for 46% of overall mortality [1]. The rapid increase in coronary artery disease in Iran and many other developing countries in the world is associated with marked changes in life style regarding diet and physical activity over the past two decades [2], [3]. Based on the recent large population based study in Tehran, two-thirds of Iranian middle-aged women are either overweight or obese [4].
While obesity is as an important risk factor for coronary artery disease it is refractory to treatment once it is established and this may be especially true in women from a lower social class who are less concerned about thinness and dieting [5], [6], [7]. While efforts should be still focused on the prevention of overweight and obesity in the community, exploring predictors of coronary artery disease in this steadily increasing population of overweight and obese female may help to establish strategies for reducing coronary artery disease or delaying it's developing in this population. On the other hand, the available evidence suggests that the specific level of risk for coronary artery disease at a given level of obesity may be different depending on societal conditions [8]. There is, however, no information on social differences in the prevalence of coronary artery disease in Iran.
This study, therefore, aimed to compare coronary artery disease risk factors and educational levels in a group of Iranian overweight and obese women with and without coronary artery disease in Rasht city, Iran.

Subjects and method
A total of 853 women with symptoms suspicious to be related to heart disease was examined in the main public heart clinic in Rasht, a city in north of Iran from 2000 to 2003. Among this group of patients a number of 518 women were either overweight or obese and 114 were taking antilipid or antihypertensive medications. Data analysis included 404 overweight and obese women who were not taking either antilipid or antihypertensive medications. The women were examined clinically and underwent
Results
Characteristics of the subjects and comparison of risk factors between two groups of normal and coronary patients are given in Table 1. Mean BMI was not different between two groups indicating that the severity of obesity was the same in the two groups. These data showed that mean age, waist circumference, systolic and diastolic blood pressure, serum level of triglyceride, lipoprotein (a) and total cholesterol were higher in patients with coronary artery disease than normal women. Fig. 1 shows
Discussion
This study indicated that increasing age and diabetes are the only independent predictors of coronary artery disease in this population of overweight and obese patients while many of the other major coronary risk factors were higher in the patients with coronary artery disease than normal group. It is well known that advancing age is a major, independent risk factor for coronary artery disease [9]. However, mean age in the coronary artery diseased patients in this study is low indicating that

2007, International Journal of CardiologyCitation Excerpt :There is less information on the association of socioeconomic factors and gender with obesity related comorbidities in developing countries. Available data show that obesity [5] and coronary artery disease [6] are inversely related to educational level in Iranian women, but not in men. Data on gender and social difference in health risks related to obesity are helpful in developing preventive programs regarding chronic diseases.
