Resum
BACKGROUND
Despite some evidences about protective or triggering role of opium use in patients with coronary artery disease, the exact role of opium is still under question. The current study aimed to address the relation of opium dependence on the severity and extension of myocardial infarction (MI) and its related mortality.
METHODS
The study population consisted of 460 consecutive patients (239 opium addicts and 221 non-addicts) with first acute MI. Study information was extracted from hospital recorded files as well as face to face interview.
RESULTS
In-hospital mortality in opium addicted patients was numerically lower than another group (5.4% versus 8.2%), but this difference was not statistically significant. Regarding types of MI, anterior wall MI was higher in non-addicted patients than addicts (36.4% versus 26.4%). Among patients with anterior wall MI, early mortality was significantly higher in non-addicted compared to addicted subjects (20.0% versus 7.9% P = 0.043). The main associated factors of in-hospital mortality due to acute MI in addicts were advanced age and family history of coronary artery disease and in non-addicts were advanced age and hypertension.
CONCLUSIONS
In current study total in-hospital mortality was not different between opium addicted and non-addicted groups but opium may reduce the occurrence of anterior wall MI and its related early mortality.
