B-type natriuretic peptide levels have played a vital role in diagnosing and prognosticating heart failure. However, physician-scientists at the University of Alabama at Birmingham Marnix E. Heersink School of Medicine have found that BNP levels may not be an effective prognostic tool in heart failure among patients with a ventricular assist device. Their study published in the American Journal of Cardiology showed that BNP levels were high in end-stage heart failure patients with cardiogenic shock, but lose their prognostic value in VAD recipients.
