Abstract
BACKGROUNDS: Carperitide is a recombinantly produced intravenous formulation of human atrial natriuretic peptide. Despite of negative impacts of nesiritide on clinical outcomes for acute heart failure (AHF), carperitide has been used for around a half of Japanese AHF patients as a vasodilator based on limited evidences. We sought to determine the effect of carperitide compared to nitrates in the early care for AHF patients treated with vasodilators.
METHODS AND RESULTS: We conducted a cohort study of patients admitted with AHF to 808 hospitals from April 2012 to March 2014. Patients were extracted from 1,422,703 hospitalizations according to ICD-10 heart failure codes. Patients who had sepsis or mechanical supports during hospitalization were excluded. Outcomes were in-hospital death, length of hospitalization and cost of hospitalization. Among 76,924 patients, 45,595 were in patients treated with either carperitide or nitrates during the first 2 days (carperitide; 33,386, nitrates; 12,209). After application of inverse probability of treatment weighting with variables including demographics, comorbidities and treatments, there was perfect balance in both groups. Patients who were treated with carperitide had substantially higher covariate adjusted in-hospital mortality (HR 1.49 95%CI 1.35-1.64), longer length of hospitalization (Coefficients 0.062 95%CI 0.048 to 0.076) and greater cost of hospitalization (Coefficients 0.024 95%CI 0.010 to 0.037) compared to those treated with nitrates.
CONCLUSIONS: In Japanese AHF patients during their early inpatient care, carperitide use was significantly associated with worse outcomes when compared to nitrates use, suggesting the routine use of carperitide might not be recommended as a first-line vasodilator for AHF.
