Title: [Indication for percutaneous transluminal coronary angioplasty based on quality of life of patients with angina pectoris]. Author: Hayashi T, Kawaguchi K, Kotake C, Seo T, Toda T, Kobayashi K, Kohashi N, Iida N. Journal: J Cardiol; 1997 Jan; 29(1):13-22. PubMed ID: 9023675. Abstract: The changes in quality of life (QOL) before and after percutaneous transluminal coronary angioplasty (PTCA) were investigated to establish criteria for determining whether patients with angina pectoris should undergo PTCA. The QOL was surveyed twice by self-completed questionnaire for QOL by Iida and Kohashi (QUIK) before and about 4 months after PTCA in 84 patients (mean age 62.8 +/- 10.1 years) with angina pectoris. High QUIK score reflects a poor QOL, of which the internal consistency was 0.86, demonstrating high reliability. The subjects were classified into three groups according to the changes of total QUIK score before and after PTCA (I: QOL improved 31.0%, II: QOL unchanged 48.8%, III: QOL worsened 20.2%). Age, gender, total QUIK score prior to PTCA, presence of anginal pain, complications extent and degree of coronary artery stenosis, and left ventricular ejection fraction were compared between the three groups. The total QUIK score prior to PTCA in the improved QOL group was higher than that in the worsened QOL group (11.6 vs 5.1, p < 0.01). Most patients showing a poor QOL prior to PTCA demonstrated an improvement in their QOL after PTCA. The number of patients with anginal pain prior to PTCA was high in the improved QOL group (35.8%, p < 0.05). Percutaneous transluminal coronary angioplasty might not aggravate QOL (12.1%, p = 0.1) in patients with single-vessel disease. In patients with multivessel disease, PTCA might not improve (35.3%) but also might aggravate QOL (25.5%). Multivariate analysis showed that PTCA improved QOL in male or sixty-ager patients and in patients with a total QUIK score of 10 or more prior to PTCA (p < 0.01). The total QUIK score, presence of anginal pain and extent of coronary artery stenosis prior to PTCA, gender and age are factors predicting QOL after PTCA. The adaptation of PTCA for those patients should be prudently and inclusively taken into consideration to extend their QOL.[Abstract] [Full Text] [Related] [New Search]
