Serum concentrations of asymmetric and symmetric dimethylarginine are associated with mortality in acute heart failure patients.
Ontology highlight
ABSTRACT: BACKGROUND:Serum concentrations of asymmetric (ADMA) and symmetric (SDMA) dimethylarginine are established predictors of total and cardiovascular mortality. However, the predictive capacity of ADMA and SDMA for hospital and 3-months mortality of patients with acute heart failure (AHF) is unknown. METHODS & RESULTS:Out of 152 included AHF patients, 79 (52%) were female, and the mean patient age was 75.2?±?10.3?years. Hospital and three-month mortality rates were 14.5% and 27.4%, respectively. Serum ADMA and SDMA levels at admission, determined by reversed phase high performance liquid chromatography, were higher in patients having at least one of the three signs implying venous volume overload (enlarged liver, ascites, peripheral edema), a consequence of right-sided heart failure, compared to patients without those signs. Univariable logistic regression analyses revealed a significant positive association of ADMA and SDMA concentrations with hospital mortality [odds ratio (OR) and 95% confidence interval (CI) per standard deviation (SD) increase: 2.22 (1.37-3.79), p?=?0.002, and 2.04 (1.34-3.18), p?=?0.001, respectively], and 3-months mortality [2.06 (1.36-3.26), p?=?0.001, and 2.52 (1.67-4.04), p?
