Usefulness of the CHA2DS2-VASC Score to Predict Adverse Outcomes in Patients Having Percutaneous Coronary...

Area of Science:

• Cardiology
• Clinical Risk Stratification
• Interventional Cardiology

Background:

• The CHA2DS2-VASC score is established for predicting stroke risk in atrial fibrillation.
• Its utility in patients with coronary artery disease (CAD) post-percutaneous coronary intervention (PCI) remains unexplored.
• Risk stratification is crucial for managing long-term outcomes in PCI patients.

Purpose of the Study:

• To evaluate the CHA2DS2-VASC score's effectiveness in predicting clinical outcomes in patients after PCI.
• To assess the association between CHA2DS2-VASC score and long-term mortality and major adverse cardiovascular events post-PCI.

Main Methods:

• Retrospective analysis of 12,785 consecutive patients undergoing PCI.
• CHA2DS2-VASC score calculated at the time of index PCI.
• Assessment of 1- and 5-year clinical outcomes, including all-cause mortality and mortality or myocardial infarction.

Main Results:

• Mean CHA2DS2-VASC score was 3.7 ± 1.7; 59.1% of patients scored 3-5.
• Higher CHA2DS2-VASC scores significantly correlated with increased rates of primary and secondary outcomes at 1 and 5 years.
• Mortality was 10 times higher for patients with a score of 5 versus 1.
• The score demonstrated significant predictive power for all-cause mortality (C-index 0.73) and death/MI (C-index 0.72).

Conclusions:

• The CHA2DS2-VASC score is a simple, effective tool for predicting long-term clinical outcomes in patients undergoing PCI.
• Its application extends beyond stroke prevention to risk stratification in CAD patients post-intervention.
• This score can aid clinicians in identifying high-risk PCI patients for closer monitoring and management.
