Association patterns of Atrial Fibrillation with symptoms of metabolic syndrome

Background: Atrial fibrillation (AF) is the common cardiac arrhythmia in which heart beats irregularly usually greater than 100 beats per minutes. AF is well-documented public health problem causing substantial mortality and morbidity. Metabolic syndrome (MS) is a collection of metabolic risk factors like diabetes, hypertension, dyslipidemia, obesity and impaired glucose level that exists in one person. The aim of the present study is to find the relation between AF and MS.Methods: 100 patients of AF were sampled from Punjab Institute of Cardiology, Lahore from December, 2014 to June 2015. These patients were divided into two AF groups, 50 without MS and 50 with MS. 25 healthy subjects were also included for the comparison. Lipid profile was assessed by chemistry analyzer and serum insulin was measured by ELISA.Results: In our population, there was significantly high levels of insulin resistance (IR) and obesity in AF groups (without MS and with MS) as compared with healthy subjects (P<0.05). Highly significant differences was observed in relation with other parameters e.g. hypertension, hypertriglyceridemia, HDL-C among the studied groups (P<0.05). Significant positive correlation was observed between insulin and lipid profile (TC, TG, LDL) while inverse with HDL.Conclusion: The indictors of metabolic syndrome were significantly correlated with AF in the studied subjects, while IR was found significantly higher in MS group.
