To treatment his patient population, percutaneous coronary intervention (PCI) is a principal method. To date survival and revascularization are still emphasized outcome indicators. However, quality of life (QOL) after PCI is yet little in known. The purpose of this study was to assess whether change in quality of life for patients with CAD after undergoing PCI.
Methods: Patients were recruite from a southern medical center from Octorber 2010 to April 2011. Sixty-four patients who had angina with/without ST elevation Myocardial Infraction (78.1% vs. 21.9%) and admitted for an emergency PCI were recruited in this study. SF-36 and SAQ was used to measure QOL for these sample patients. This tool has been popularly using to evaluate QOL among many patients population. After informed consent signed, participants were asked to fill out the SAQ and SF-36 for 3 times. Data regarding first time of QOL for the participants were collected before them undergoing their PCI. Then, their QOL were followed up twice by telephone and when patients came back to their clinic for checking in one and three months later, respectively. By using repeated measures of GEE, independent samples t-test, effect size, differences in quality of life and relative risk factors among those 3 phases were compared.
Results: The majority of participants were men (n=52, 81.3%), aged 59±13.2. There were 38 (59.3%) patients in less severity (Killip I) of myocardial infraction. Three of 5 in SAQ domains in level of QOL were increased significantly( P＜0.001) over time from before PCI to 1 month after PCI, and from 1 month to 3 month after PCI . Six of 8 of SF36 domains in level of QOL were increased significantly( P＜0.001) over time from before PCI to 1 month after PCI, and from 1 month to 3 month after PCI. After PCI, the SF36 effect sizes (0.48 to 2.56) were all improved in all domains. SAQ effect sizes were all improved in all domains (0.34 to 1.91).
Discussion: The results of this study showed that patients with CAD perceived improving their QOL after PCI procedure. The perception of QOL seems continuously getting better after undergoing their PCI. Proper patients education and nursing interventions should be introduced for those patient population immediately post-PCI to promote patients’ QOL.
