Abstract
BACKGROUND
Carbohydrate antigen 125 (CA125) has emerged as a new biomarker in heart failure. The objective of the study is to determine whether serum CA125 levels predict total mortality and readmissions at one year in patients >70 years old with acute heart failure (AHF) and preserved ejection fraction (PEF).
METHODS
Multicenter prospective observational study, which included 359 patients (mean age 81.5 years). The primary endpoint was total all-cause mortality and total readmissions for AHF at 1 year. A negative binomial regression technique was used to evaluate the association between CA125 and both endpoints.
RESULTS
At one year of follow-up, 87 deaths (24.2%) were registered. The patients in the lower quartile of CA125 had a lower crude mortality rate (14.4%, 26.7, 26.7, 29.2; p=0.09). After multivariate analysis, the CA125 value was positively associated with a higher risk (p=0.009). Such association was also positive but borderline significant for the risk of readmissions (p=0.089).
CONCLUSIONS
In a population older than 70 years hospitalized for AHF with PEF, elevated levels of CA125 are associated with an increased risk of death at one year of follow-up. The association with readmission for AHF was more uncertain. Low levels of CA125 identifies a subgroup at low-risk.
