Quality of Life in Patients Receiving Percutaneous Coronary Intervention and Optimal Medical Therapy in Ho Chi Minh City, Vietnam

Introduction: This study assessed Health-Related Quality of Life (HRQOL) of patients with Acute Coronary Syndrome (ACS) 6 to 12 months after receiving Percutaneous Coronary Intervention (PCI) and/or Optimal Medical Therapy (OMT) at a hospital in Ho Chi Minh City, Vietnam. Methods: A cross-sectional study was conducted on 113 patients. Data on demographic, lifestyle behaviours, and HRQOL were collected using a structured questionnaire through face-to-face interviews. HRQOL was measured using EQ-5D-5L and EQ-VAS. Data on co-morbidity and other clinical characteristics were extracted from hospital records. Bivariate and multivariable linear regression models were run to test the differences in EQ-5D-5L utility index and EQ-VAS scores between PCI/OMT and OMT alone groups. Results: EQ-5D-5L utility index and EQ-VAS scores were lower in PCI/OMT compared to OMT groups, although the differences were not clinically meaningful. Weight status, smoking, and physical activity were associated with EQ-5D-5L utility index score, whereas only physical activity was associated with EQ-VAS score. Conclusion: The findings suggested that improving sufficient physical activity levels and stopping smoking after PCI or/and OMT may help increase HRQOL among ACS patients.
