Health-related Quality of life and its related factors in patients undergoing Coronary angioplasty, Zanjan, northwest Iran

Abstract

Background: The quality of life of patients after percutaneous coronary interventions (PCI) is definitely not clear. The aim of this study was to evaluate the health-related quality of life (HRQL) and related factors in patients undergoing angioplasty. Methods: This analytical cross-sectional study was performed on patients with coronary artery disease who underwent PCI and had a history of hospitalization in Zanjan, Iran in 2020.  920 patients based on specific inclusion and exclusion criteria were included by census method.The study tool was a 36-item Short Form Health Survey questionnaire)SF-36). Mann-Whitney U test and Kruskal-Wallis tests were used to data analysis in SPSS 19 with a significance level of 5%. Results: In total, 70%(644people) were female, 86% (791) angina, 34.2% (315) Myocardial infarction. median (IQR) of age, Physical Component Summary(PCS), and Mental component summary (MCS) were 60 (15), 65.78(9.48), 64.18 (7.68), respectively. Multivariate linear regression showed that PCI type (B=-2.52, p=0.013) and age (B= -0.21,p<0.001) had a negative effect  and education level(B=3.15, p=0.002), income(B=1.34, p=0.002), angina(B=1.27, p=0.02)  and number of drugs(B=0.609, p<0.001)  had a positive effect on PCS. Also, PCI type (B=-3.024, p=0.001), age(B=-0.123, p<0.001), diabetes(B=-1.19, p=0.008), blood pressure(B=-0.728, p=0.05)  and duration of disease(B=-0.309, p=0.022)  had a negative effect and education, income(B=2.57, p=0.022), number of drugs(B=0.615, p<0.001)  had a positive effect on MCS. Conclusion: Age, type of PCI, diabetes, blood pressure, level of education, income were the most important factors related to HRQL of cardiovascular patients undergoing coronary angioplasty. Therefore, to improve the HLQL, these factors must be considered.
