Key result
New-onset hospital proteinuria in ASCVD patients is linked to ~30% higher CV mortality risk.
Why the study?
Evidence regarding the prognostic value of new-onset proteinuria during hospitalization among patients with ASCVD is lacking.
Does new-onset proteinuria during hospitalization predict cardiovascular mortality and adverse kidney outcomes in patients with ASCVD?
Cohort (n=34,429)
Yes
Does new-onset proteinuria during hospitalization predict cardiovascular mortality and adverse kidney outcomes in patients with ASCVD?
Hazard Ratio: 1.3 (95% CI 1.07–1.57)
New-onset proteinuria during hospitalization in ASCVD patients is an independent prognostic marker for increased cardiovascular mortality and adverse kidney outcomes.
BACKGROUND: Evidence regarding the prognostic value of new-onset proteinuria during hospitalization among patients with atherosclerotic cardiovascular disease (ASCVD) is lacking. OBJECTIVES: We aimed to examine the associations of new-onset proteinuria during hospitalization with cardiovascular (CV) mortality and composite kidney outcomes after discharge. METHODS: , >40% decline in estimated glomerular filtration rate, or end stage renal disease. The associations between new-onset proteinuria and outcomes were assessed by Cox proportional hazard models. RESULTS: In this nationwide cohort of 34,429 inpatients with the mean age of 64 years, new-onset proteinuria occurred in 7.5% of the population. With a mean follow-up of 4.6 years, new-onset proteinuria during hospitalization was significantly associated with an increased risk of CV mortality (HR: 1.30; 95% CI: 1.07-1.57) and adverse kidney outcomes (HR: 1.50; 95% CI: 1.04-2.17). The association between new-onset proteinuria and CV mortality was independent of the occurrence of acute kidney injury and showed similar trend across subgroups and multiple sensitivity analyses. CONCLUSIONS: The presence of new-onset proteinuria during hospitalization among ASCVD patients demonstrated significant prognostic value and should be carefully monitored to improve patient care.

Su et al. (2025) conducted a cohort in Atherosclerotic cardiovascular disease (ASCVD) (n=34,429). New-onset proteinuria during hospitalization vs. No new-onset proteinuria was evaluated on Cardiovascular (CV) mortality (HR 1.30, 95% CI 1.07-1.57). New-onset proteinuria during hospitalization in patients with ASCVD was significantly associated with an increased risk of cardiovascular mortality (HR 1.30; 95% CI 1.07-1.57).
