SYNTAX积分与急性心肌梗死急诊介入治疗后心血管事件的关系

SYNTAX score and cardiovascular events in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention

Objective:To investigate the predictive effect of SYNTAX score for in-hospital and one-year prognosis outcome in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods:A total of 312 patients with STEMI undergoing primary PCI were divided into three groups based on SYNTAX scores which were calculated by angiography results. Group A (n＝170) was defined as baseline SYNTAX score (bSSC) ＜22, group B bSSC＝22-32 (n＝90), group C bSSC＞32 (n＝52).Results:(1) Group B and group C had a higher proportion of patients with diabetes, a higher CK-MB, UA, fasting glucose compared with group A (P＜0.05). (2) The proportions of patients with severe adverse cardiovascular events in-hospital in three groups were 6.6% (n＝11), 31.1% (n＝28), 36.5% (n＝19) respectively (P＜0.05). (3) For patients whose follow-up periods were between (14.2±0.8) months, Kaplan-Meier survival analysis showed log-rank （P＜0.001 ) was found among major adverse cardiovascular events (MACE), all-cause death, non-fatal MI, unplanned revascularization for ischemia, rehospitalization due to heart failure. (4) By multivariable analysis, bSSC and rSSC were found to be significant independent predictor for all ischemic outcomes at year 1, including MACE (HR＝1.059, 95% CI: 1.035-1.083, P＜0.001; HR＝1.056, 95% CI: 1.033-1.081, P＜0.001). Conclusion:The SYNTAX score is an independent predictor for in-hospital as well as long-term mortality and MACE in patients with acute STEMI undergoing primary PCI.
