INTRODUCTION: Microalbuminuria (MAU), a complication of diabetes, is closely related to cardiovascular events. A fragmented QRS (fQRS) in the electrocardiogram (ECG) was found to be strongly associated to cardiovascular morbidity and mortality.
OBJECTIVE: The aim of this study was to assess the association between a fQRS and MAU in patients with type 2 diabetes mellitus (T2DM).
PATIENTS AND METHODS: One hundred and twenty-seven patients (mean age, 50.49 years; 44.01% male) with T2DM of at least six months duration and at least two urine albumin/creatinine ratios (ACRs) available were enrolled into the study between December 2015 and May 2016. All patients underwent ECG and echocardiography, and were taken blood and urine samples. Patients were divided into two groups according to presence of fQRS (group 1) or absence of fQRS (group 2).
RESULTS: Both groups had similar baseline characteristics. MAU and glycosylated hemoglobin (HbA1c) levels and left ventricular end-diastolic diameter (LVEDd) were increased in patients with a fQRS in the ECG (p=0.002, p=0.02, and p=0.007, respectively). Univariate and multivariate logistic regression analysis showed MAU and an increased LVEDd to be independent risk factors for the presence of a fQRS in the ECG of T2DM patients.
DISCUSSION AND CONCLUSIONS: In this study, a fQRS was associated to MAU. In T2DM, MAU may be related to subclinical diastolic and systolic dysfunction.
