Abstract
Background:
Different scores based on anatomical and/or clinical features have been developed for risk stratification of patients undergoing percutaneous coronary intervention (PCI). Studies comparing the ability of these different models in predicting major adverse cardiac and cerebrovascular events (MACCE) in patients submitted to primary PCI are limited.
Objectives:
The aim of this study was to compare the ability of the scores SYNTAX (SS), Clinical SYNTAX (CSS), ACEF, and modified ACEF (ACEFMod) to predict MACCE in patients with ST-elevation myocardial infarction (STEMI) submitted to primary PCI.
Methods:
We analyzed 311 consecutive patients with STEMI submitted to primary PCI between April/2011 and December/2015. The area under the ROC curve was calculated to evaluate the ability of these scores in predicting MACCE. P-values were considered significant at < 0.05.
Results:
Mean age of the patients was 60.2 ± 12.0 years, 35.4% were females, and 22.5% had diabetes. MACCE occurred in 23.8% of the patients. The area under the ROC curve was 0.586 (p = 0.028) for ACEF, 0.616 (p = 0.003) for SS, 0.623 (p = 0.002) for ACEFMod, and 0.658 (p < 0.001) for CSS. In multivariate analysis, only high SS (p = 0.011) and CSS (p = 0.002) were independent predictors of MACCE.
Conclusions:
High SS and CSS were independent predictors of MACCE. In our cohort of STEMI patients undergoing primary PCI, pure anatomical SS calculated at the baseline coronary angiography was a useful tool to predict MACCE. (Int J Cardiovasc Sci. 2017; [online].ahead print, PP.0-0)
