Prediction of adverse events after acute myocardial infarction: derivation and external validation of an extended CHA₂DS₂-VASc score model.

ABSTRACT:

Background

The CHA₂DS₂-VASc score predicts poor prognosis in patients with acute myocardial infarction (AMI), with or without atrial fibrillation. In this observational study, we aimed to evaluate the CHA₂DS₂-VASc score by itself and extended with clinical data to predict adverse events in patients after AMI.

Methods

In this longitudinal observational study, we used a cohort of 955 patients hospitalised for AMI at Västmanland County Hospital, Västerås, Sweden, to derive prediction models. The CHA₂DS₂-VASc score alone and combined with clinical data (systolic blood pressure, creatinine level, ST-segment elevation and diuretic use at discharge) was analysed using Cox regression to evaluate the risk of major adve
