Objectives:This study aims to determine if patients with acute myocardial infarction differ in illness perception and secondary prevention outcomes depending on the treatment they ***:A repeated measures design was used to compare patients with acute myocardial infarction receiving three different treatment modalities:ST-elevation myocardial infarction treated by primary percutaneous coronary intervention,ST-elevation myocardial infarction treated by thrombolytic therapy,and non ST-elevation myocardial infarction treated by medication.A convenient sampling technique was used to recruit 206 patients with acute myocardial infarction who agreed to participate in the current ***'illness perception,physical activity,and demographical and clinical data were collected during hospital admission and again at 6 ***:A total of 186 patients completed the *** showed that the primary percutaneous coronary intervention group perceived their illness as acute rather than chronic(P=0.034)and has lower personal control(P=0.032),higher treatment control(P=0.025),and higher perception of illness coherence(P=0.022)compared with patients receiving thrombolytic therapy and treated after non-ST segment ***,they report low control of their blood pressure(P=0.013)and less physical activity(P=0.001).Conclusion:The results of this study revealed that patients'treated with primary percutaneous coronary intervention had negative illness perception and limited behavioral changes 6 months after hospitalization in comparison with other treatment modalities such as percutaneous coronary intervention and thrombolytic *** research is recommended to confirm this association with longer follow-up study and among different cultures.
