INTRODUCTION: Cerebrovascular event (CVE) is major cause of mortality and morbidity after coronary artery bypass surgery (CABG). There is no available data in literature investigating correlation between SYNTAX and clinical SYNTAX score (CSS) and CVE after isolated CABG. The aim of the study was to investigate predicting risk of CVE with SYNTAX and CSS. METHODS: 1850 patients underwent isolated CABG between October 2011 to December 2013 were included in the study in our hospital. 249 patients included in our study after eliminating patients having exclusion criteria. CVE included transient ischemic events and strokes in 30 days after CABG and two groups were determined as post-operative CVE (+) (PoCVE+) and post-operative CVE(-) (PoCVE-). SYNTAX score and additional clinical parameters (age, left ventricular ejection fraction (LVEF), glomerular filtration rate (GFR)) to calculate CSS were recorded for patients using last coronary angiography before isolated CABG. RESULTS: In present study, age (p=0.002), total cholesterol (p=0.048), glucose (p=0.022), uric acid (p=0.032), creatinine (p=0.022), neutrophil count (p=0.06), circumflex-saphenous grafting (CX-SVG) (p=0.01), CSS (p=0.003) were found statistically higher in PoCVE(+) group. Additionally, LVEF (p=0.019) and GFR (p=0.013) were detected lower in PoCVE(+) group. logistic regression of significant parameters showed that, average age (p=0.017), increased glucose levels (p=0.08), existence of CX-SVG (p=0.011) and CSS (p=0,026) were found contributed factors. CSS >8 predicts CVE with sensitivity of 78.6, specificity of 68.9 DISCUSSION AND CONCLUSION: This study showed CSS might be a useful and practical score to predict CVE in patients who planned to undergo CABG therefore precautions might be taken before surgery for these patients. |
