Background<\/strong> \u2014 The effects of sex on the prognostic implications of natriuretic peptide (NP) elevation have not been fully elucidated in the population.<\/p>\n

Objectives<\/strong> \u2014 The purpose of this study was to examine if sex modifies associations of NPs with mortality and hospitalization.<\/p>\n

Methods<\/strong> \u2014 In a population-based retrospective cohort study, we identified all patients (aged \u226540 years) undergoing NP testing in Ontario, Canada (2015-2020). We examined for the presence of sex-by-NP interactions for 1-year outcomes and conducted sex-specific analyses for continuously increasing NP concentrations.<\/p>\n

Results<\/strong> \u2014 We studied 91,017 individuals with B-type natriuretic peptide (BNP) tests (median 75 years; 48.0% females) and 81,578 individuals with N-terminal pro-BNP (NT-proBNP) tests (74 years; 48.6% females). Adjusted 1-year risks of all-cause mortality at any given NP concentration were higher in males than females. For example, 1-year mortality at a BNP of 400 ng\/L was 16.8% in females and 21.6% in males. At an NT-proBNP of 900 ng\/L, 1-year mortality was 14.2% in females and 18.5% in males. However, there were also significant sex interactions with BNP (P = 0.002) and NT-proBNP (P = 0.03) for mortality outcomes. When we examined cardiovascular hospitalizations, there was also a significant sex-by-NP interaction. For BNP, the risk of cardiovascular hospitalization was higher in males at lower concentrations but was higher in females at higher concentrations (P-interaction = 0.005). For NT-proBNP, the risk of cardiovascular hospitalization was higher in males at lower NP concentrations, but the gap narrowed at higher NP levels (P interaction = 0.03).<\/p>\n

Conclusions<\/strong> \u2014 Sex modifies the association between NP concentrations and all-cause mortality or cardiovascular hospitalizations. Prognostically, interpretation of NP levels should consider effect modification by sex.<\/p>\n","protected":false},"excerpt":{"rendered":"
