Background: d-ROMs test developed to determine the degree of individual oxidative stress may predict cardiovascular events.
Methods and results: 265 patients (204 men, 61 women; age, 65±13years) who had been treated for cardiovascular disease were divided evenly by quartile of baseline d-ROMs levels, and were followed up. During the observation periods of 2.66±1.47years, there were 14 (5%) deaths, 8 (3%) cardiovascular deaths, 13 (5%) major adverse cardiovascular events (MACEs), and 51 (19%) all cardiovascular events including heart failure, cardiovascular surgery, and revascularization. Log-rank tests demonstrated that the patients in the 4th quartile (d-ROMs≧395.00U.CARR) had a higher incidence rate of cardiovascular death than those in the 2nd quartile (d-ROMs 286.00-335.00, p=0.022). In multivariate Cox regression analysis, even after adjustment for age, sex, coronary risk factors, C-reactive protein, and renal function, high d-ROMs was a risk factor for all-cause death [adjusted HR of 4th vs. 1st quartile, 10.791 (95% confidence interval 1.032-112.805), p=0.047], and all cardiovascular events [HR of 4th vs. 1st quartile, 2.651 (95% confidence interval 1.138-6.177), p=0.024].
Conclusions: Our results suggest that d-ROMs is a useful oxidative stress marker to assess prognosis and risk of further cardiovascular events.
