Previous studies reported the potential associations between dietary patterns and the risk of coronary heart disease (CHD) in adulthood, however a consistent perspective has not been established to date. Herein, we carried out this meta-analysis to evaluate the associations between dietary patterns and the risk of CHD. MEDLINE and EBSCO were searched for relevant articles published up to April 2015. A total of 35 articles (reporting 37 original studies) met the inclusion criteria and were included in the present meta-analysis. The decreased risk of CHD was shown for the highest compared with the lowest categories of healthy/prudent dietary patterns (odds ratio (OR) = 0.67; 95% confidence interval (CI): 0.60, 0.75; p < 0.00001) and alcohol consumption (OR = 0.68; 95% CI: 0.59, 0.78; p < 0.00001). There was evidence of an increased risk of CHD in the highest compared with the lowest categories of the unhealthy/Western-type dietary patterns (OR = 1.45; 95% CI: 1.05, 2.01; p = 0.02). The results of this meta-analysis indicate that different dietary patterns may be associated with the risk of CHD.

Zhang et al. (2015) conducted a meta-analysis in Coronary heart disease. Healthy/prudent dietary patterns, unhealthy/Western-type dietary patterns, and alcohol consumption vs. Lowest category of dietary pattern or alcohol consumption was evaluated on Risk of coronary heart disease (CHD) (OR 0.67, 95% CI 0.60-0.75, p=<0.00001). Healthy dietary patterns (OR 0.67; 95% CI 0.60-0.75) and alcohol (OR 0.68) decreased CHD risk, while Western-type diets increased risk (OR 1.45; 95% CI 1.05-2.01).
