Predictive Value of PRECISE DAPT Score in STEMI Patients After Primary PCI

Study Overview
=================
Brief Summary
-----------------
To investigate the predictive value of PRECISE DAPT score in relation to coronary slow flow & other short term major adverse cardiovascular events (MACE) post PPCI .

Detailed Description
-----------------
Coronary artery disease (CAD) is the leading cause of death around the world and more than 4 million people die every year due to CAD in Europe.[1] The incidence of ST elevation myocardial infarction (STEMI) appears to be declining; however, it is still an important issue in cardiovascular medicine.[2] Initial risk assessment is important for STEMI to estimate adverse cardiovascular outcomes. Previous studies demonstrated that increased age, advanced Killip class, heart rate, arterial hypotension, increased serum creatinine, white blood cell counts, and hemoglobin levels were predictors of in-hospital and early mortality in patients with STEMI treated with primary percutaneous coronary intervention (PPCI).[3,4 ]Therefore, risk scores including the aforementioned parameters were developed to estimate mortality in patients with STEMI. No-reflow is still a challenging major issue in the management of the patients with STEMI undergoing primary PCI. It is defined as inadequate myocardial perfusionthrough a given segment of the coronary circulation without angiographic evidence of mechanical vessel obstructionas [5] Angiographic no-reflow defined as less than Thrombolysis In Myocardial Infarction (TIMI) 3 flow [6] and angiographic success was defined as TIMI Grade 3 Flow . PRECISE-DAPT score includes age, creatinine clearance, white blood cell counts, hemoglobin levels, and prior spontaneous bleeding [7]. All these factors have a close relationship with coronary artery disease (CAD) and complications [8-10]. Therefore, in this study, we aimed to evaluate the association of admission PRECISE-DAPT score with the development of slow flow & bleeding & othershort term cardiovascular complications that develop in patients with STEMI treated with primary PCI.
