Quality of Life of Patients with Acute Myocardial Infarction Treated with Percutaneous Coronary Intervention: Comparison of Quality of Life at Discharge and 6 Months after Discharge

Abstract

Objective: The present study investigated the health-related quality of life (QOL) of patients with acute myocardial infarction (AMI) who were treated with percutaneous coronary intervention (PCI). Methods: Forty-three patients were asked to complete the SF-36 questionnaire at discharge and 6 months after discharge. The SF-36 consists of 8 subscales: Physical Functioning (PF), Role Physical (RP), Bodily Pain (BP), General Health perception (GH), Vitality (VT), Social Functioning (SF), Role Emotional (RE), and Mental Health (MH). We calculated mean scores and standard deviations for these 8 subscales at discharge and 6 months after discharge. Values were compared using the paired student ttest. Results: The PF and BP scores after 6 months were significantly higher than those at discharge, but there were no significant differences in the other subscales. Conclusions: Some of the physical parameters of healthrelated QOL may improve 6 months after discharge in AMI patients treated with PCI. Since PCI may relieve symptoms such chest pain and chest discomfort, these patients can gradually extend their daily activities. While the physical state may improve, mental health-related QOL does not appear to improve 6 months after discharge.

Factors Related to the Improvement of Quality of Life at 6 Months after Discharge for Myocardial Infarction Patients Treated with Percutaneous Coronary Intervention

“…However, the scores for GH at discharge were low, and these low scores continued 6 months after discharge ( Table 2 ). Our results were similar to those of previous reports 3 ) .…”

“…It has also been reported that AMI patients treated with IVCT do not have an improved quality of life (QOL); however, AMI patients treated with PCI have improved QOL. Shibayama 3 ) reported that the physical parameters of health-related QOL improved 6 months after discharge for AMI patients treated with PCI. Janzon 4 ) also reported that the physical QOL scores of patients with unstable angina treated with PCI were higher than for patients with unstable angina treated with IVCT.…”
