SYNTAX RESIDUAL COMO PREDICTOR DE EFECTOS ADVERSOS POST ANGIOPLASTIA PERCUTANEA, SEGUIMIENTO A 3 AÑOS

ABSTRACT Introduction: The Syntax Residual Score (SRs) is the calculation of the SYNTAX SCORE I (SS) score after revascularization, the cut point between high and low, has been agreed upon in 8 points. Material and methods: We carried out a retrospective longitudinal cohort study in our center, calculating SRs after coronary angioplasty in 52 patients, with implantation of drug-eluting stents, with 8 points as cut-off point, clinical follow-up was performed at 3 years; It is divided into two groups, group 1 (SR 8) finding the following; mortality 0% group 1, 3.8% group 2 with a value of p = 0.017, events of Acute Coronary Syndrome 0% group 1, 9.6% group 2, p = 0.001, Need to repeat revascularization (TVR), 1.9% group 1, 17.3% group 2, p = 0.002. Conclusions: SR calculation is a useful quantitative tool to determine whether revascularization is complete or incomplete, with the latter existence a statistically significant association between residual syntax score of less than 8 points, mortality, presence of acute coronary syndrome and need to repeat revascularization coronary disease at 3 years of follow-up, that is, it has a long-term prognostic value. Currently, we suggest that a functional anatomical evaluation of coronary lesions be carried out to guide the intervention and use intravascular methods to optimize results and affect the rate of adverse events.
