There was a trend of a higher rate of heart failure, defined by the presence of congestive symptoms, with an elevated prohormone of brain natriuretic peptide (pro BNP) level and a reduced ejection fraction of 35% or less either on initial presentation (23 cases representing 80%) or on readmission within 30 days after discharge (6 cases representing 20%), and it was statistically insignificant. Here, NPPB is linked to heart failure.
