Abstract:
Objective To explore the relationship between metabolic syndrome(MS) and corrected QT(QTc) interval prolongation.Methods A total of 1 260 participants having electrocardiogram examinations,aged over 18 years old from June 2015 to June 2016 were included and divided into the MS group and non-MS group.QTc was calculated according to the Bazett formula.The Logistic regression model was established for exploring the association between MS and QTc.Results There were 63 cases of QTc interval prolongation in the MS group,however,40 cases in the non-MS group(P＜0.01).In the unadjusted model,MS was a risk factor of QTc interval prolongation[OR =6.36,95 ％ CI(2.34,8.67),P＜ 0.01].After further adjusting confounders,MS was still correlated with QTc interval prolongation[OR =4.11,95 ％ CI(2.09,7.13,P＜ 0.01].In the study of the relationship between the MS groups with QTc interval prolongation,after adjusting confoundingfactors,only abdominal obesity[OR=2.76,95％ CI(1.43,7.56),P＜0.01] and hypertriglyceridemia[OR=1.75,95％CI(1.22,4.31),P=0.013)] were closely correlated with QTc interval prolongation.Conclusion MS is an independent risk factor of QTc interval prolongation.It is especially important to strengthen the management of blood lipid and abdominal circumference.
