does analgesic effect of opium hamper the adverse effects of severe coronary artery disease on quality of life in addicted patients?

conclusions despite higher rate of morbidities in opium-addicted patients compared to non-addicted ones, subscales of qol were similar between the two groups. high preoperative hba1c and low ejection fraction appeared to be determinants of poor qol in the opium-addicted patients. background opium is a unique substance, regarding its analgesic effects. this may change the deteriorating effects of coronary artery disease (cad) on quality of life (qol) in addicted patients. objectives we studied the qol in opium-addicted and non-addicted cad patients so as to determine the relationship between cad risk factors and the subscales of their qol. patients and methods demographic and laboratory data as well as coronary artery risk factors were obtained and sf-36 questionnaire was completed through interviews with 268 (38 opium-addicted and 230 non-addicted) patients with cad who were candidates for isolated coronary artery bypass at tehran heart center. results mean euro score in addicted and non-addicted patients were 3.7 ± 7.6 and 2.4 ± 2.2 respectively (p = 0.036). in addicted group, higher preoperative hba1c was associated with low physical function score (β = −0.395, p = 0.021). low ejection fraction could negatively affect the general health (β = 0.394, p = 0.014) and mental health (β = 0.292, p = 0.015) subscales in the addicted group.
