Myocardial Repolarization Parameters and Neutrophil-to-Lymphocyte Ratio are Associated with Cardiotoxicity in Carbon Monoxide Poisoning.

Myocardial Repolarization Parameters and Neutrophil-to-Lymphocyte Ratio are Associated with Cardiotoxicity in Carbon Monoxide Poisoning. Cardiovasc Toxicol. 2019 Dec 20;: Authors: Temrel TA, Bilge S Abstract The present study aims to examine the clinical values of complete blood count (CBC) bioindicators and corrected QT (QTc), Tpeak - Tend interval (Tp-e), Tpeak dispersion (Tp disp), and Tp-e/QT ratio that are the parameters of myocardial repolarization (M-rep) for cardiotoxicity, which develops due to acute carbon monoxide (CO) intoxication in patients admitted to the emergency service. This retrospective, cross-sectional, observational, and single-center study was conducted between April and June 2019. Statistical analysis was performed using the SPSS 23.0 software. Data of 234 participants were analyzed. Of these, 54.9% (n = 129) were female. Neutrophil-to-lymphocyte ratio (NLR), QTc, Tp-e values were significantly high in the CO intoxication group (p < 0.001, p < 0.001, and p < 0.001, respectively), whereas Tp-e/QTc ratio was significantly lower in the CO intoxication group than that in the control group (p < 0.001). NLR, Tp-e, Tp disp values were significantly high in the myocardial injury (M-inj) group (p < 0.001, p = 0.003, and p = 0.018, respectively). Furthermore, Tp-e/QTc ratio was significantly low in the M-inj group (p = 0.002). M-rep parameters and NLR are associate...
