Dietary intake of patients with angiographically defined coronary artery disease and that of healthy controls in Iran.
OBJECTIVE
The aim of this study was to investigate the relationship between dietary intake and biomarkers of cardiovascular risk in individuals with and without angiographically defined coronary artery disease.


METHODS
Coronary angiography was undertaken in 445 individuals who were divided into those with significant disease (>50% occlusion) (Angio+ (n=273)) and those with <50% coronary artery occlusion (Angio- (n=172)). Apparently healthy, non-symptomatic individuals (n=443) were considered as the control group. Dietary intake was assessed using a 24-h dietary recall method and dietary analysis was performed using Diet Plan 6 software.


RESULTS
Concentrations of starch, saturated fatty acids, polyunsaturated fatty acids, magnesium, iron and copper in the control group were less than those in the other groups (P<0.05), but after adjusting for total energy intake these differences were no longer apparent. The mean intake of protein, cholesterol, phosphorus, zinc, zinc/copper ratio, selenium, iodine, carotene, vitamin E, niacin, pantothene and pyridoxine was less in the control group compared with the other two groups (P<0.05), and the mean of sugar, fiber, transfatty acids, manganese, folate and vitamin C was higher in the control group than in other groups (P<0.05). Lipid profile values between the three groups did not differ significantly.


CONCLUSIONS
These results indicate that the amount of intake of various nutrients can be considered as an independent risk factor for CAD. Further research on the relationship between CAD and nutrient intake, especially intake of essential micronutrients, is needed.
