Elevation of asymmetric dimethylarginine in patients with unstable angina and recurrent cardiovascular events.
We investigated the role of asymmetric dimethylarginine (ADMA) for clinical outcome of patients with unstable angina.. Forty-five patients with stable angina, 36 patients with unstable angina, and 40 healthy controls were included in this study. Coronary artery disease (CAD) patients were prospectively followed for 1 year. ADMA levels were measured at baseline and after 6 weeks using a validated ELISA. Baseline ADMA concentration in controls was significantly lower than in patients with CAD (0.59+/-0.23 vs. 0.76+/-0.17 micromol/L; P<0.001). Patients with unstable angina had significantly higher baseline ADMA levels than patients with stable angina (0.82+/-0.18 vs. 0.73+/-0.15 micromol/L; P=0.01). There was a significant reduction of ADMA levels at 6 weeks after percutaneous coronary intervention (PCI) in patients with unstable angina who experienced no recurrent cardiovascular event (from 0.81+/-0.14 to 0.73+/-0.19 micromol/L; P<0.05). In contrast, patients with unstable angina who had an event showed no significant decrease in ADMA at 6 weeks. Actuarial survival analysis showed a significantly higher event rate in patients with persistently elevated ADMA plasma concentrations.. ADMA is significantly elevated in patients with unstable angina. A reduced ADMA level at 6 weeks after PCI may indicate a decreased risk of recurrent cardiovascular events.
