The association of opium with coronary artery disease

Abstract

BACKGROUND: The effects of opium consumption on coronary artery disease are still unknown. METHODS: A cross-sectional study was conducted on 2405 patients admitted to the Angiographic Ward at Tehran Heart Center from 7 May 2005 to 13 August 2005. RESULTS: After adjusting for conventional cardiovascular risk factors, opium consumption was a significant risk factor for coronary artery disease (P=0.01 and odds ratio=1.8). Moreover, the amount of opium consumption was associated significantly with the severity of coronary atherosclerosis, as measured by clinical vessel score (r=0.2, P=0.002). CONCLUSIONS: To our knowledge, this is the first time that the adverse effects of opium consumption on coronary arteries was defined.
