ABSTRACT
BACKGROUND AND OBJECTIVES:
Heart failure is a progressive chronic disease with high morbidity and mortality. The aim of this study was to determine whether the N-terminal pro B-type natriuretic peptide (NT-proBNP) levels in the blood can predict readmission due to heart failure or cardiac death (cardiac event) following hospital discharge, and if these are a better predictive marker than a pre-discharge echocardiogram or other laboratory parameters in discharged patients with idiopathic dilated cardiomyopathy (DCM). SUBJECTS ANDMETHODS:
The outcomes of 36 patients with idiopathic DCM, diagnosed on hospital admission, were retrospectively evaluated.RESULTS:
During a mean follow-up period of 520 days, a 22.2% rate of cardiac events was observed. Evaluation of the NT-proBNPs showed the mid-term (mean 84th day after discharge) outpatient (OPD) NT-proBNP levels to be a strong predictor of cardiac events, with an area under the curve analysis of 0.90. The optimal mid-term OPD NT-proBNP cut-off level for predicting cardiac events was 1500 pg/mL, with a sensitivity and specificity of 80 and 92%, respectively; patients with levels above this threshold had a 22.9 hazard ratio for cardiac events compared to those with levels below this threshold.CONCLUSION:
The mid-term OPD plasma NT-proBNP levels were able to predict cardiac events in discharged patients with idiopathic DCM, regardless of the admission or pre-discharge NT-proBNP levels and other laboratory parameters. The measurement of OPD NT-proBNP at the mid term follow-up may be useful in outpatient therapeutic monitoring or for the development of prognostic guidelines in patients with idiopathic DCM.
