Abstract
BACKGROUND Surgical treatment methods for patients with complex coronary artery disease (CAD) who have undergone vascular reconstruction mainly include coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI). The purpose of the study aimed to compare a 1-year follow-up for the patient clinical outcomes and costs between PCI and CABG treatment. MATERIAL AND METHODS There were 840 patients enrolled in this study from July 2015 to September 2016. Among the study participants, 420 patients underwent PCI treatment and 420 patients underwent off-pump CABG. Patients costs were assessed from the perspective of the China healthcare and medical insurance system. EuroQOL 5-dimension 3 levels (EQ-5D-3L) questionnaire was used to evaluate the general health status, and the Seattle Angina Questionnaire (SAQ) was used to assess the disease-specific health status. RESULTS After a 1-year follow-up, the all-cause mortality (P=0.0337), the incidence of major adverse cardiac and cerebrovascular events (P<0.001), and additional revascularization (P<0.001) in PCI group were significantly higher than those in CABG group. Both groups have significant sustained benefits in the SAQ subscale. The CABG group had a higher score on the frequency of angina than the PCI group. In addition, the quality-adjusted life year value of PCI and CABG resulted was 0.8. The average total cost for PCI was $14 643 versus CABG cost of $13 842 (P=0.0492). CONCLUSIONS In the short-term, among the CAD patients with stable triple-vessel or left-main, costs and clinical outcomes are substantially higher for CABG than PCI. Long-term, economic, and health benefits analysis, is warranted.
