Abstract
Introduction: Percutaneous Coronary Intervention (PCI) is an advanced treatment for coronary artery disease with a high success rate, rapid effectiveness, and low complications. Assessing the quality of life in patients undergoing PCI is essential. Currently, there are very few studies conducted on this issue in Vietnam; therefore, we undertake this study
Objective: To assess the quality of life of patients with coronary artery disease before and after intervention using the EQ-5D-5L questionnaire.
Subjects: Patients who underwent successful coronary artery stenting at Cho Ray Hospital from December 2020 to May 2021.
Study design: Descriptive cross-sectional study with follow-up
Results: The study observed 136 patients meeting the research criteria, with a mean age of 63.8 ± 10.4 years, and a male predominance (61.7%). Among them, 79.4% had acute coronary syndrome, while 20.6% had chronic coronary syndrome. Common cardiovascular risk factors included hypertension (75%), dyslipidemia (75%), smoking (54.4%), and diabetes mellitus (21.3%). The average EQ-5D-5L quality of life score of patients before coronary artery stenting was 0.2 ± 0.3 points. After 3 months, the EQ-5D-5L score significantly increased to 0.9 ± 0.1 points (p<0.01). The average EQ-VAS score reflecting the patients' overall health perception before stenting was 43.4 ± 9.4 points. After 3 months, the EQ-VAS score significantly increased to 84 ± 5.9 points (p<0.01).
Conclusion: Through our study, we found that coronary artery stenting improves the quality of life as assessed by the EQ-5D-5L questionare.
