The aim of this work is to study the additive value of Syntax II to Syntax I score in assessment of infarct size in patients with ST elevation myocardial infarction managed with primary percutaneous coronary intervention.
Patients and methods: This is cross sectional study; enrolled 150 patients with acute ST elevation myocardial infarction underwent primary percutaneous coronary intervention from June 2018 till January 2020 in the Catheterization laboratory of Cardiology department, Zagazig university Hospitals and Nasr City Insurance Hospital. History taking, clinical examination, laboratory investigation, electrocardiography and echocardiography done for all cases. Infarct size predicted from ECG, peak CK, CK MB, Troponin, ejection fraction and wall motion score index. Coronary angiography was 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 diabetes mellitus, hypertension, smoking, chronic obstructive pulmonary disease, smoking and peripheral arterial disease. There was positive relationship between infarct size and high Syntax I and high Syntax II score with p < /p>
