Effects of metabolic syndrome on atrial fibrillation in essential hypertensive patients without left ventricular hypertrophy

Abstract

Objective To investigate the effects of metabolic syndrome (MS) on the atrial fibrillation (AF) in essential hypertensive (EH) patients without left ventricular hypertrophy. Methods 972 EH without left ventricular hypertrophy were divided into EH + non MS group (n=606) and EH + MS group (n=366) according to MS. Incidence of AF was compared between two groups. Results (1) Incidence of AF in EH + MS group was higher than that in EH + non MS group (12.84% VS 6.93%, P<0.01). (2) Left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDd), interventricular septum thickness (IVS), left ventricular posterior wall thickness (LVPW) and left ventricular mass (LVM) were higher in EH + MS group than that in EH + non MS group (P<0.01), however, no difference of left ventricular mass index (LVMI) and ejection fraction (EF) were found between the two groups.
