The prognostic value of CHA₂DS₂-VASc and GRACE risk scores in patients with ACS

Area of Science:

• Cardiology
• Clinical Risk Assessment

Background:

• Cardiovascular diseases are a leading cause of mortality in Western societies.
• Accurate ischemic risk assessment is crucial for guiding therapeutic interventions in individual patients.

Purpose of the Study:

• To compare the prognostic capabilities of the GRACE score and the CHA2DS2-VASc score.
• To determine which score better predicts ischemic risk in patients undergoing angioplasty.

Main Methods:

• A consecutive series of patients undergoing Percutaneous Coronary Intervention (PCI) for Acute Coronary Disease or elective PCI were included.
• The GRACE score and CHA2DS2-VASc score were calculated for all participants.
• Patient outcomes were followed for 2 years.

Main Results:

• The study included 667 patients with a mean age of 61 ± 11 years.
• The CHA2DS2-VASc score demonstrated a marginally better prediction of future ischemic events (AUC 0.624) compared to the GRACE score (AUC 0.608).
• The GRACE score's 3-year predicted incidence was also compared.

Conclusions:

• The CHA2DS2-VASc score showed a marginally superior ability to predict Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) compared to the GRACE score in patients who underwent angioplasty.
• This suggests the CHA2DS2-VASc score may be a more effective tool for risk stratification in this patient population.
