The Relation Between CHA2DS2-VASc Score, Initial TIMI Flow Grades and In-Hospital Mortality in Patients Presenting...

Area of Science:

• Cardiology
• Clinical Risk Stratification

Background:

• The CHA2DS2-VASc score assesses stroke risk in atrial fibrillation but is also used for other cardiovascular conditions.
• Initial Thrombolysis in Myocardial Infarction (TIMI) flow is a critical determinant of outcomes in acute myocardial infarction (AMI).

Purpose of the Study:

• To investigate the association between the CHA2DS2-VASc score and initial TIMI flow in patients with AMI.
• To evaluate the CHA2DS2-VASc score's predictive value for in-hospital clinical outcomes, including mortality, in AMI patients.

Main Methods:

• Retrospective analysis of 750 patients hospitalized with a first diagnosis of AMI.
• Recording and comparison of initial and post-procedural TIMI flow grades.
• Analysis of CHA2DS2-VASc scores in relation to TIMI flow and in-hospital mortality.

Main Results:

• A higher CHA2DS2-VASc score was significantly associated with lower initial TIMI flow (TIMI 0-1).
• A CHA2DS2-VASc score of 3 was the optimal cut-off for predicting low initial TIMI flow.
• The CHA2DS2-VASc score was an independent predictor of in-hospital mortality, with a median score of 4 in non-survivors.

Conclusions:

• The CHA2DS2-VASc score is a valuable tool for predicting both initial coronary artery perfusion and in-hospital mortality in AMI patients.
• Elevated CHA2DS2-VASc scores identify AMI patients at higher risk for adverse outcomes, including poor initial flow and increased mortality.
