Objective: Light blood cell (WBC) count to mean platelet volume (MPV) percentage (WMR) is associated with major adverse cardiovascular events in patients with non-ST elevation acute coronary syndrome (NSTEMI). the tertiles. Results: WMR was significantly higher in the CCNG2 patient group compared to the control group (p 0,001). WMR among low, intermediate and high score tertiles were determined to be 89026, 1090042 and 150065, respectively (p 0,001). In receiver operating characteristics (ROC) analysis, WMR 960 3-Hydroxydodecanoic acid expected a SYNTAX score 23 with 80.6% level of sensitivity and 67.6% specificity (AUC: 0.756; 95% CI: 0.685 – 0.818; p 0.0001) and a WMR 1360 predicted a SYNTAX score 33 with 71.4% level of sensitivity and 93% specificity (AUC: 0.840; 95%CI: 0.777 – 0.892; p 0.0001). Conclusions: WMR value was significantly elevated in NSTEMI individuals, compared to settings. Higher WMR was associated with higher SYNTAX score in individuals with NSTEMI. WMR 3-Hydroxydodecanoic acid may be used to forecast severity of the CAD and to implement risk stratification in individuals with NSTEMI. None. Referrals 1. Libby P.
