the mortality rate of myocardial infraction patients with and without opium dependen

conclusions there was no meaningful relationship between the mortality rate of patients with mi who were either opium-dependent or non-opium-dependent. the number of re-hospitalizations due to heart problems was meaningfully higher in the opium-dependent patients; hence, educating people and training them on the destructive effects of opium, specifically in patients with heart conditions is highly recommended. background myocardial infarction (mi) is a heart condition caused by the suspension of blood circulation in a part of the myocardium. there are different risk factors contributing to a heart attack. some believe that endorphins and endogenous opioids play an important role in causing mis. objectives this study intended to determine the relationship between opium dependency and mortality rate among patients with mi. patients and methods this retrospective study investigated patients who had mi for the first time and were hospitalized in the coronary care unit (ccu) of khatamolanbia hospital in zahedan, iran, from 2007 to 2010. these patients were either opium dependent or not. four hundred patients were selected. the patients’ possibilities of death and re-hospitalization after the first mi were confirmed over the phone. data was analyzed through t-test and chi-squared test. results of all the patients, 19.5% were opium-dependent. the mortality rate in the non-opium-dependent group was 5.9%, while in the dependent group this rate was 11.5% (p = 0.072). the number of re-hospitalizations due to heart problems was higher in the opium-dependent patients (p < 0.001).
