Carbohydrate antigen 125 (CA125) has been shown to be a surrogate of systemic congestion. We sought to explore whether BUN and CA125 modulate the mortality risk associated with HDLDs following a hospitalization for acute heart failure (AHF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>We analysed 1389 consecutive patients discharged for AHF. CA125 and BUN were measured at a mean of 72 \u00b1 12 h after admission. HDLDs (\u2265120 mg\/day in furosemide equivalent dose) were interacted to a four-level variable according to CA125 (&amp;gt;35 U\/mL) and BUN (above the median), and related to all-cause mortality. At a median follow-up of 21 months, 561 (40.4%) patients died. The use of HDLDs was independently associated with increased mortality [hazard ratio (HR) 1.23, 95% confidence interval (CI) 1.01\u20131.50], but this association was not homogeneous across CA125\u2013BUN categories (P for interaction &amp;lt;0.001). In patients with normal CA125, use of HDLDs was associated with high mortality if BUN was above the median (HR 2.29, 95% 1.51\u20133.46), but not in those with BUN below the median (HR 1.22, 95% CI 0.73\u20132.04). Conversely, in patients with high CA125, HDLDs showed an association with increased survival if BUN was above the median (HR 0.73, 95% CI 0.55\u20130.98) but was associated with increased mortality in those with BUN below the median (HR 1.94, 95% CI 1.36\u20132.76).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The risk associated with HDLDs in patients after hospitalization for AHF was dependent on the levels of BUN and CA125.
