N-terminal pro-brain natriuretic peptide, C-reactive protein, and urinary albumin levels as predictors of mortality and cardiovascular events in older adults
Open accessAbstract
CONTEXT: B-type natriuretic peptides have been shown to predict cardiovascular disease in apparently healthy individuals but their predictive ability for mortality and future cardiovascular events compared with C-reactive protein (CRP) and urinary albumin/creatinine ratio is unknown. OBJECTIVE: To assess the prognostic value of the N-amino terminal fragment of the prohormone brain natriuretic peptide (NT-proBNP) vs CRP and urinary albumin/creatinine ratio in an older adult population. DESIGN, SETTING, AND PARTICIPANTS: A population-based prospective study of 764 participants aged 50 to 89 years from a community in Copenhagen, Denmark, in which 658 participants provided blood and urinary samples and were examined between September 1, 1998, and January 24, 2000. Of these participants, 626 without heart or renal failure were enrolled. A subgroup of 537 had no history of cardiovascular disease at baseline. During 5 years of follow-up (to December 31, 2003), 94 participants died and 65 developed a first major cardiovascular event. MAIN OUTCOME MEASURES: Risk of mortality and first major cardiovascular event by baseline levels of NT-proBNP, CRP, and urinary albumin/creatinine ratio levels. RESULTS: After adjustment for the cardiovascular risk factors of age, sex, smoking, diabetes mellitus, hypertension or ischemic heart disease, total cholesterol, and serum creatinine, the hazard ratio (HR) of mortality for values above the 80th percentile of NT-proBNP was 1.96 (95% confidence interval [CI], 1.21-3.19); for CRP, 1.46 (95% CI, 0.89-2.24); and for urinary albumin/creatinine ratio, 1.88 (95% CI, 1.18-2.98). Additional adjustment for left ventricular systolic dysfunction did not markedly attenuate the predictive value of NT-proBNP (HR, 1.82; 95% CI, 1.11-2.98). The absolute unadjusted increase in mortality risk for participants with values above the 80th percentile vs equal to or below the 80th percentile was 24.5% for NT-proBNP, 7.8% for CRP, and 19.5% for urinary albumin/creatinine ratio. The NT-proBNP levels were associated with first major cardiovascular events (nonfatal myocardial infarction, fatal coronary heart disease, unstable angina, heart failure, stroke, and transient ischemic attack) with an adjusted HR of 3.24 (95% CI, 1.80-5.79) vs 1.02 (95% CI, 0.56-1.85) for CRP and 2.32 (95% CI, 1.33-4.05) for urinary albumin/creatinine ratio when comparing participants with values above the 80th percentile with those with values equal to or below the 80th percentile. CONCLUSIONS: Measurements of NT-proBNP provide prognostic information of mortality and first major cardiovascular events beyond traditional risk factors. NT-proBNP was a stronger risk biomarker for cardiovascular disease and death than CRP was in nonhospitalized individuals aged 50 to 89 years.

In multiple epidemiological studies, moderately increased albuminuria is an independent risk marker for cardiovascular death.
“In multiple epidemiological studies, moderately increased albuminuria is an independent risk marker for cardiovascular death (481-483).”
From Guidelines and Recommendations for Laboratory Analysis in the Diagnosis and Management of Diabetes Mellitus (2023) · cites this paper as [482]
The Comment section (page unavailable) describes urinary albumin excretion as a well-known risk marker and says this study found it independently predicted death and a first major cardiovascular event. The Mortality and Cardiovascular Events sections report all-cause death and a composite cardiovascular outcome, respectively; they do not establish an independent association specifically with cardiovascular death. The passages also do not identify the studied levels as moderately increased albuminuria. (LLM, conf=0.84)
Experimental — accuracy not yet measuredAlbuminuria is a well-established cardiovascular risk marker.
“Albuminuria (formerly microalbuminuria) are a well-established cardiovascular risk marker, in which increases over time to macroalbuminuria (.300 mg/day) are associated with kidney disease and an increased risk for progression to endstage renal disease.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
