Evaluation of electrocardiographic ventricular repolarization parameters in stable coronary artery disease
Aim: To examine the relationship between the SYNTAX score (SS) and cardiac repolarization parameterssuch as cQTd and Tp-e values, and Tp-e/QT, Tp-e/JT, Tp-e/QTc, and Tp-e/JTc ratios in patients who havestable angina pectoris.Methods: 12-lead resting electrocardiograms (ECGs) and SS of 160 patients (51 female and 109 male)undergoing coronary angiography with the pre-diagnosis of stable angina pectoris were evaluated. Patientswith a SS below 22 were classified as Group 1 (low-SYNTAX), and those above 22 (high-SYNTAX) as Group2. Forty-four patients with normal coronary angiography were included in Group 3.Results: Mean age of the patients was 62.4±9.1 years. The heart rate, QRS, QT, cQT and JT durations betweenthe groups were similar. In addition, relatively recent ventricular repolarization indices such as Tp-e intervaland Tp-e/QT, Tp-e/JT, Tp-e/QTc, and Tp-e/JTc ratios were also not substantially different between groups.Conclusion: Several surface ECG predictors of ventricular arrhythmias, including QTd, JT and Tp-e intervalsand their ratios to QT and JT, are not significantly correlated with SYNTAX score-assessed CAD severity inpatients with stable angina pectoris
