Abstract

Background: The SYNTAX score and clinical SYNTAX score are markers in prognosis of major adverse cardiac events in acute myocardial infarction after percutaneous coronary intervention. Objectives: To analyze some related factors to the SYNTAX score and the clinical SYNTAX score. To determine their prognostic value for early major adverse cardiac events in acute myocardial infarction patients treated with percutaneous coronary intervention. Materials and methods: A cross-sectional and prospective study of 80 patients with acute myocardial infarction treated with percutaneous coronary intervention at Can Tho Central General Hospital. Results: The mean of SYNTAX score was 15.6 ± 8.06. The mean clinical SYNTAX score was 37.2 ± 13.3. A high clinical SYNTAX score had a significant relationship with multi-vessel, bifurcations, total occlusions and thrombus coronary artery disease (p<0.05). During the six-month follow-up period, 11 cases of major adverse cardiac events appeared. Kaplan-Meier showed that the high clinical SYNTAX score had a significant relationship with all-cause mortality (p=0.022). The clinical SYNTAX score ≥35.15 with a sensitivity of 90.9% and a specificity of 53.6% which was a high predictive value for major adverse cardiac events compared to SYNTAX score (AUC=0.749; p=0.04). Conclusions: The high clinical SYNTAX score not only indicated greater complexity and severity of coronary artery disease but also predicted higher risk of major adverse cardiac events than SYNTAX score.
