ABSTRACT
Background
Multivessel coronary artery disease is a challenge in clinical practice. An individualized approach should consider not only the patient characteristics, but also a multidisciplinary approach, together with the Heart Team. Multiple angiographic scores have been proposed with the aim of quantifying the risk associated with multivessel coronary artery disease. Residual SYNTAX score has been proposed as a method to systematically characterize and quantify residual coronary disease after percutaneous coronary intervention. There are few data in the literature correlating the residual SYNTAX score in patients with ST-segment elevation myocardial infarction undergoing pharmacoinvasive strategy. The objective of this study was to evaluate the SYNTAX score and residual SYNTAX score as predictors of in-hospital and medium-term outcomes (180 to 380 days) in patients with multivessel coronary artery disease in the setting of ST-segment elevation myocardial infarction, after successful fibrinolytic therapy.
Methods
In a cross-sectional, analytical, and prospective study, we evaluated residual SYNTAX score as predictor of in-hospital and medium-term outcomes (6 months to 1 year), in patients with multivessel coronary artery disease, in the setting of ST-segment elevation myocardial infarction after pharmacoinvasive strategy.
Results
Between August 2019 and December 2020, 108 patients with ST-segment elevation myocardial infarction after fibrinolysis, with reperfusion criteria, were analyzed. The mean SYNTAX score was 13.98 (±4.87) and the mean residual SYNTAX score was 7.56 (±4.47). High residual SYNTAX score was associated with contrast-induced nephropathy and major adverse cardiac event. It was also an independent predictor of major adverse cardiac event with a 9.69-fold increased risk (p=0.0274).
Conclusion
High residual SYNTAX score confers worse prognosis in patients with ST-segment elevation myocardial infarction after pharmacoinvasive strategy.
