Cross-Sectional Associations between Homoarginine, Intermediate Phenotypes, and Atrial Fibrillation in the Community—The Gutenberg Health Study
2018
Homoarginine has come into the focus of interest as a biomarker for cardiovascular disease. Atrial fibrillation (AF) causes a substantial increase in morbidity and mortality. Whether circulating homoarginine is associated with occurrence or persistence of AF and may serve as a new predictive biomarker remains unknown. We measured plasma levels of homoarginine in the population-based Gutenberg health study (3761 patients included, of them 51.7% males), mean age 55.6 ±
Homoarginine Levels are Regulated by L-Arginine: Glycine Amidinotransferase and Affect Stroke Outcome: Results from Human and Murine Studies
2013
Background— Endogenous arginine homologues, including homoarginine, have been identified as novel biomarkers for cardiovascular disease and outcomes. Our studies of human cohorts and a confirmatory murine model associated the arginine homologue homoarginine and its metabolism with stroke pathology and outcome. Methods and Results— Increasing homoarginine levels were independently associated with a reduction in all-cause mortality in patients with ischemic stroke (7.4 years of follow-up; hazard ratio for 1-SD homoarginine, 0.79 [95% confidence interval, 0.64–0.96]; P =0.019; n=389). Homoarginine was also independently associated with the National Institutes of Health Stroke Scale+age score …
Low Homoarginine Levels in the Prognosis of Patients With Acute Chest Pain.
2016
Background The endogenous amino acid homoarginine predicts mortality in cerebro‐ and cardiovascular disease. The objective was to explore whether homoarginine is associated with atrial fibrillation ( AF ) and outcome in patients with acute chest pain. Methods and Results One thousand six hundred forty‐nine patients with acute chest pain were consecutively enrolled in this study, of whom 589 were diagnosed acute coronary syndrome ( ACS ). On admission, plasma concentrations of homoarginine as well as brain natriuretic peptide ( BNP ), and high‐sensitivity assayed troponin I (hsTnI) were determined along with electrocardiography ( ECG ) variables. During a median follow‐up of 183 days, 60 ma…
