Effectiveness of the integration of different types of quantitative and qualitative assessment indicators for the patients with ischemic heart disease who underwent percutaneous coronary intervention (PCI)

In Japan during recent years, percutaneous coronary intervention (PCI) has been a main therapeutic method for ischemic heart disease (IHD). However, there is little known about early outcomes such as Health-Related Quality of Life (QOL) and life rhythm of daily living (LRDL) post PCI. The purpose of this study is to examine the effectiveness of integrating different types of quantitative and qualitative assessment indicators for patients with ischemic heart disease who underwent PCI. We used the SF36 ver2 (Medical Outcomes study 36- Item Short-Form Health Survey) and Accelerometer (AMI, Actigraph). Patients (n=18) who underwent PCI at one public hospital were assessed on QOL and LRDL during hospitalization to discharge, approximately 10 days. Furthermore, 6 patients were selected for a semi-structure interview about life after the discharge. There were significant differences observed in the items of Sleep Minutes (Smin) and Percentage of Sleep (Pslp) during the test period. The item of Activity Index (Actx) decreased significantly during the period of 1 to 3 days after discharge and during the period 4 to 6 days after discharge, compared with the day before discharge (p <; 0.05). The scores of RE (Role Emotional) significantly decreased a week from discharge, compared with the score at the time of discharge (p <; 0.05). Patients´ experiences were divided into five categories utilizing three different quantitative and qualitative assessment indicators for comprehensive evaluation. Basic results indicated: 1) Patient´s sleep quality was improved following discharge (evaluated by Actigraph), 2) Patient´s QOL was not improved (evaluated by SF36), and 3) The subjects were not fully functioning to their previous level due to decline in physical activity and attitude toward continuation of lifestyle improvement after PCI treatment (semi-structure interviews). The combined uses of three assessment indicators provide comprehensively more accurate evaluation of t- e patient conditions.
