Relationship between peculiarities of atrial fibrillation, body mass index and adipokines levels

Abstract

Aim: To assess the value of body mass index (BMI) and adipokine levels in predicting development of atrial fibrillation (AF) in the general population.Methods: Three hundred and ninety eight patients were examined for the presence of phenotype metabolically healthy obesity (MHO), according to the Wildman criteria; adipokine levels were assessed by enzyme immunoassay method; AF was assessed by electrocardiography (ECG) and/or by ECG diurnal monitoring.Results: Obesity (group 1) and overweight (group 2) was present in 23.7% and 42.0% of participants; while 21.1% were normal body weight (group 3) and 13.1% had a BMI < 19.9 kg/m2 (group 4). Phenotype MHO was detected in 19.6% patients. At follow-up, 32.4% of participants developed AF. Adiponectin levels were significantly higher in MHO patients as compared to metabolically unhealthy patients with abdominal obesity (AO). High molecular weight adiponectin (HMVAN) levels were significantly decreased in patients of groups 1 and 4, as compared to groups 2 and 3. Correlation between AF and HMWAN was determined by regressive analysis in patients of 1st and 4th groups (β = -0.24, P = 0.003 and β = -0.26, P = 0.002, respectively).Conclusion: The probability of developing AF increases with AO and decreased BMI, which is accompanied by a change in HMVAN levels. In MHO patients, the probability of AF developing is identical with persons having normal BMI
