Background
Increased asymmetrical dimethylarginine (
ADMA
) and
NT
pro‐
BNP
concentrations have been associated with mortality in patients with cardiovascular (
CV
) disease and the general population. The use of these prognostic markers in an older population is not established yet. The aim of the present study was to investigate the prognostic value of age, sex,
BMI
, co‐medication and
CV
laboratory risk markers in geriatric care patients.
Materials and methods
In this prospective observational single‐centre cohort study data of long‐term geriatric care patients were collected. Blood samples were collected between 14.09.2009 and 16.12.2009, and mortality was recorded up to 90 months.
ADMA
, its symmetric isomer
SDMA
, L‐arginine,
NT
pro‐
BNP
and
CRP
were determined at study entry. Simple associations of risk factors for survival period were explored by Spearman correlation coefficient. Significant univariate predictors for survival period were used in the Cox proportional hazard model.
Results
A total of 481 patients were screened, and data from 449 patients were analysed. A total of 381 patients died during the observation period. Full data sets from 344 patients were used for Cox regression analysis. Male sex, older age, lower
BMI
, use of neuroleptic medicine, peripheral artery disease, and elevated plasma concentrations of
ADMA
,
NT
pro‐
BNP
, and
CRP
were significant predictors of mortality.
Conclusion
The concentration of
ADMA
and
NT
pro‐
BNP
may be used as an early risk marker for overall mortality in geriatric care. Neuroleptic medicine is associated with increased mortality in this population.
