CHA2DS2-VASc Score as a Predictor of Thrombus Burden and Clinical Outcomes in Patients Undergoing PPCI.

CHA2DS2-VASc Score as a Predictor of Thrombus Burden, No-Reflow Phenomenon and Clinical Outcomes in Patients Undergoing Primary Percutaneous Coronary Intervention

Aim of the work is to evaluate the use CHA2DS2-VASc score in predicting no-reflow phenomenon and its impact on short term primary percutaneous coronary intervention outcomes (in-hospital mortality) and long term (6 months) incidence of MACE ( major adverse cardiac event ) in patients with ST segment elevation Myocardial infarction who underwent primary primary percutaneous coronary intervention

Large intracoronary thrombus burden is known to be associated with reduced procedural success during the Primary Percutaneous Coronary Intervention (PPCI), larger infarct size, increased ischemic complications and mortality. No-Reflow phenomenon is related to higher incidence of complications, and short- and long-term morbidity and mortality in acute STEMI patients.

Although many risk factors were suggested, Tragically there's no widely accepted risk stratification method to anticipate these complications.

CHA2DS2-VASc score is a sum of several risk factors for thromboembolism. It is considered a clinical indicator of thromboembolic diseases and is recommended by the current guidelines for the estimation of thromboembolic events in patients with atrial fibrillation.

In this study, we evaluate the use CHA2DS2-VASc score as a novel rapid simple tool for predicting No-reflow and clinical outcomes among patients with STEMI who underwent primary PCI.

Inclusion Criteria:

• Subjects with STEMI and undergoing primary Primary percutaneous coronary intervention.
• Patient Loaded pre-procedural with using with Aspirin 300 mg plus Ticagrelor 180 mg or Clopidogrel 600 mg.

Exclusion Criteria:

• Patients with chest pain more than 48 hours
• Patients not eligible for primary PCI
