Background
Left main coronary artery (LMCA) bifurcational stenosis is considered as a complex coronary artery disease (CAD) and successful percutaneous coronary intervention (PCI) ofLM bifurcational stenosis could substantially decrease total SYNTAX score. However, the impact of residual SYNTAX score after successful PCI of LMbifurcational stenosis on long-term patient prognosis is unknown.
Methods
We chose patients with LMCA bifurcational stenosis who successfully treated by PCI. SYNTAX score was calculated before and after PCI. Cox proportional hazard regression analysis and Kaplan-Meier curve were used to estimate the relationship between residual SYNTAX score and all-cause mortality after PCI of LM bifurcational stenosis.
Results
A total of 78 patients with LM bifurcational stenosis were chosen (mean age60±11, 81% male). Pre-procedural median SYNTAX score was significantly decreased after successful PCI of LMCA bifurcational stenosis (28±9.2 vs. 2±3.1,p<0.001). After adjustment of age, gender, and Medina classification, post-procedural residual SYNTAX score was not associated with all-cause mortality in the long term (HR=1.01, 95% CI 0.82-1.25, p=0.918). Also Kaplan-Meier curve estimation didn’t show a significant difference between patients with residual SYNTAX score 0 and ≥ 1 (Figure 1).
Conclusion
Successful PCI of LMCA bifurcational stenosis substantially decreases total SYNTAX score. Residual SYNTAX score after PCI of LMCA bifurcational stenosis is not related to long-term patient prognosis.
