Ejection fraction, B-type natriuretic peptide and risk of stroke and acute myocardial infarction among patients with heart failure.

Patients with rEF had a significantly higher rate of stroke and AMI vs pEF patients, as did patients with H-BNP vs L-BNP. The present study is the first to show the real-world association of EF and BNP (alone and in combination) with clinical outcomes, further supporting the recommendation to use these markers in clinical practice. These results may help to guide future recommendations and improve the clinical management of HF.
