Clinical and Nonclinical Predictors of Health-Related Quality of Life, One Year After Percutaneous Coronary Intervention (PCI).

Abstract

Background: According to the high prevalence of cardiovascular diseases and the need to know the factors associated with the important outcome of quality of life after therapeutic interventions, this study was conducted with the aim of determining the factors associated with health-related quality of life (HRQoL), one year after percutaneous coronary intervention (PCI). Methods: This cross-sectional study was conducted on 912 patients undergoing PCI in a referral-educational hospital in Iran. Data collection was done using a HRQoL questionnaire (SF-36) and a checklist containing other study variables by face-to-face interview. To analyze the variables, the descriptive statistics and multivariate linear regression were used. All statistical analyses were performed using IBM SPSS Statistics for Windows, Version 16.0 (IBM Corp., Armonk, NY, USA). In this study, the significance level is p < 0.05. Results: The mean ± SD age of the participants was 59.47 ± 9.94 years, and 62.94% of them were male. The mean score of HRQoL in men (69.44 ± 21.18) was significantly higher than women (60.26 ± 21.8) (p < 0.001). In linear regression analysis, the variables of unemployment, age, loss of spouse, comorbidity, re-angioplasty, rehospitalization after PCI were significantly associated with to HRQoL. Conclusions: Better HRQoL after PCI may be linked to a care strategy that takes into account both clinical and nonclinical aspects.
