The long-term prognostic value of the derivatives of reactive oxidative metabolites (d-ROMs) oxidative stress test, which measures hydroperoxide in blood, has not been fully investigated.We administered the d-ROMs test to 265 patients with cardiovascular disease (204 men, 61 women; age, 65 ± 13 years) and followed these patients for up to 10 years. During the observational period of 5.82 (2.47-8.34) years, 31 (12%) patients died, including 20 (8%) of cardiovascular death, and 33 (12%) had major adverse cardiovascular events (MACEs). Cox regression analysis revealed that patients with a d-ROMs value ≥395 U.CARR had a greater risk for all-cause mortality [unadjusted hazard ratio (95% confidence interval), 3.586 (1.772-7.257)], cardiovascular death [7.034 (2.805-17.640)], and MACEs [4.440 (2.237-8.814)] (p 0.001 for all). In a model adjusted for age, sex, estimated glomerular filtration rate, C-reactive protein, diabetes, hypertension, hyperlipidemia, coronary artery diseases, current smoking, and log-transformed brain natriuretic peptide, all-cause death [2.311 (1.059-5.135), p = 0.036], cardiovascular death [4.398 (1.599-12.099), p = 0.004], MACEs [2.696 (1.266-5.739), p = 0.010] were still significant in patients with high d-ROMS values.A high d-ROMs value is an independent predictor of the long-term risk of cardiovascular mortality. A d-ROMs value of 395 U.CARR was considered to be an appropriate threshold for distinguishing prognosis. |
