Background: The purpose of this study is to investigate the additive benefit of Syntax II to Syntax I score in assessment of infarct size in patients with STEMI managed with primary PCI. Methods: This is a cross sectional study; enrolled 150 patients with acute STEMI who did primary PCI from June 2018 till January 2020 in the Catheterization laboratory of Cardiology department, Zagazig university Hospitals and Nasr City Insurance Hospital. History, physical examination, laboratory investigation, ECG, and transthoracic echocardiography were made for all cases. Infarct size was estimated from ECG, peak CK, CK MB, troponin, systolic function, and wall motion score index. Coronary angiography has been done then Syntax II and Syntax I scores were calculated. Results: Syntax II and Syntax I scores were calculated, and infarct size was predicted then compared to each other's and compared to many variables including DM, HTN, smoking, COPD, smoking and peripheral arterial disease. There was positive relationship between infarct size and high Syntax I and high Syntax II score with p <0.001 with more sensitivity and specificity with Syntax II score, also there was positive relationship between infarct size and DM, HTN and peripheral vascular disease with significant p value. Conclusion: In patients with STEMI who did primary PCI, Syntax II score was more predictive than Syntax I for evaluation of infarct size.
