(Oxford Univ Press, 2021) Sengul, Cihan; Sen, Ahmet; Barutcu, Suleyman; Cakir, Cayan; Sarikaya, Remzi
Objective: Hyperbilirubinemia is associated with protection against various oxidative stress-mediated diseases. We aimed to investigate the association between bilirubin and novel electrocardiography (ECG)-based ventricular repolarization parameters. Methods: We enrolled 201 healthy men with mild hyperbilirubinemia (group 1) and 219 healthy men with normal bilirubin levels (group 2). The Tpeak-Tend (Tp-e) interval (defined as the interval from the peak of the T wave to the end of the T wave), corrected (c) Tp-e interval, QT interval, cQT interval, and Tp-e interval/QT interval ratio were measured from leads V-5 and V-6 with 20 mm/mV amplitude and 50 mm/second rate. Results: The Tp-e interval, cTp-e interval, and Tp-e interval/QT interval ratio were significantly lower in group 1 compared with group 2. The cTp-e interval showed a significant negative correlation with total bilirubin, conjugated bilirubin, and unconjugated bilirubin. The cTp-e interval (odds ratio [OR], 0.900; P=.002) and Tp-e interval/QT interval ratio (OR, 0.922; P=.04) were significantly associated with mild hyperbilirubinemia. Conclusion: We showed the association of mild hyperbilirubinemia with decreased novel ECG-based ventricular repolarization parameters.
The Prevalence and Correlates of T-Wave Inversion in Lead Iii in Non-Obese Men
(Churchill Livingstone inc Medical Publishers, 2020) Sengul, Cihan; Cakir, Cayan; Barutcu, Suleyman; Sarikaya, Remzi
Background: T-wave inversion in lead III was linked to displacement of the base of the heart due to abdominal adipose tissue in early electrocardiography (ECG) trials. The observation of T-wave inversion in lead III in some of the pathological and physiological conditions other than obesity suggests the possibilities of different mechanisms. We aimed to investigate the prevalence and correlates of T-wave inversion in lead III in non-obese men. Method: A total of 1240 men underwent ECG, blood pressure measurement, hepatic ultrasonography, and biochemical tests from January 2019 to December 2019. We excluded 220 subjects due to predetermined criteria. The eligible 105 non-obese men with T-wave inversion in lead III and 915 non-obese men without T-wave inversion in lead III were compared with each other in terms of clinical, demographic and laboratory parameters. Results: The mean age was 27.9 years with a range of 20 to 46 years. The prevalence of T-wave inversion in lead III was 10.3%. Body mass index (BMI), blood urea nitrogen, creatinine, alanine aminotransferase, hematocrit, and the percentage of non-alcoholic fatty liver disease (NAFLD) were significantly higher in Group with T-wave inversion while alkaline phosphatase was significantly higher in Group without T-wave inversion. In multivariable analysis, NAFLD was the best independent correlate of inverted T-wave in lead III (beta = 6.215, p < 0.0001). BMI (beta = 1.448, p b 0.001) and hematocrit (beta = 1.179, p = 0.021) were the other independent correlates of T-wave inversion in lead III. Conclusion: We demonstrated the association of T-wave inversion in lead III with NAFLD, BMI, and hematocrit in non-obese men. (C) 2020 Elsevier Inc. All rights reserved.
