Short term clinical outcomes of Complex Percutaneous Coronary Intervention in patients with intermediate to high SYNTAX score: Ain Shams complex PCI Registry

Abstract

Abstract Background Risk stratification is an important and essential component in proper patient counseling when dealing with complex coronary anatomy and decision making between either coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI). The SYNTAX score was pioneered as an anatomical-based risk score that aided in this decision-making process. Objective To develop an electronic registry for patients with complex coronary anatomy with intermediate to high SYNTAX score undergoing non-emergent PCI who were indicated for CABG but either they were rejected by the surgeons or they refused it. Patients and Methods Our registry was conducted on 193 patients presented during eight months from the first of July 2021 till the end of February 2022 to Ain Shams University Hospitals and underwent PCI. Results comparing the intermediate to high SYNTAX score groups, there is a statistically significant increase in the in hospital and short term MACE and mortality with high SYNTAX score patients, while there was no difference regarding in hospital CIN. Regarding MACE it significantly increases in patients with anemia, CKD, LV dysfunction. For multivariate analysis it is shown that both incomplete revascularization and clinical SYNTAX II are independent predictors for the occurrence of short term MACE. Conclusion Both incomplete revascularization and clinical SYNTAX II score are independent predictors of short term (6 months) occurrence of MACE.
