Introduction: Angioplasty is an emergency intervention procedure which restores blood flow in a blocked artery in patients with acute myocardial infarction (MI) with ST-segment elevation. Many studies showed, opium addiction (OA) can be a risk factor for MI. However no studies showed the role of OA in pain response after primary angioplasty. In this study we aimed to compare the pain response after angioplasty in OA and non-OA group.
Method: The present study is a case control study . The study population consisted of 180 male patients (90 addicted patients and 90 non-addicted patients) who were admitted to the emergency department of Khorshid Hospital in Isfahan with a diagnosis of acute ST-elevation myocardial infarction .The required information was obtained by distributing a questionnaire before and after primary angioplasty treatment.
Results: The mean pain intensity after the intervention was assessed in the two groups and no significant difference was observed. In terms of substance use, the highest frequency was related to opium, which was 86.3%. There was no significant difference between the two groups regarding the type of myocardial infarction and in both groups, the highest frequency was related to the anterior level.
Conclusion: The mean pain intensity after emergency primary angioplasty in male patients (addicted and non-addicted) with acute myocardial infarction showed no significant difference
