There is a traditional belief among Eastern people that opium may have ameliorating effects on cardiovascular risk factors, especially diabetes; thus, it is widely used among diabetic patients. We attempted to investigate the association of opium consumption with coronary artery disease (CAD) in diabetic patients. A cross-sectional study was conducted on diabetic patients undergoing coronary angiography in our center. Out of 1925 diabetic patients included in the study, 228 were opium users, and the remaining 1697 non-opium users were used as a pool of potential comparators. Propensity scores were used to match the 228 opium consumers with 228 matched comparators for age, sex, and smoking status. The Gensini score and extent score were respectively used to assess the angiographic severity and extent of CAD. The mean Gensini score (86.9 +/- 62.7 vs. 59.6 +/- 43.4, p < 0.0001) and extent score (7.1 +/- 2.9 vs. 5.9 +/- 2.9, p < 0.0001) were significantly higher in opium user diabetic patients than in non-opium users. After adjustment for potential confounders, a dose-response relationship was observed between dose of opium and the Gensini score (beta = 0.27, p = 0.04). There were no significant differences between the routes of opium administration (inhalation vs. oral) regarding the severity and extent of CAD. In conclusion, exposure to opium in diabetic patients may be positively associated with the risk of CAD, and with the angiographically determined severity and extent of the disease. Furthermore, dosage of opium consumption may correlate with severity of CAD.
