Patients and controls were well-matched for age (mean of ~40 years for both) and had similar distributions of history of hypertension, diabetes mellitus, atrial fibrillation, values of echocardiographic parameters (including LVEF, LVESD, and LVEDD), and hemoglobin level, RDW, PDW, ALT, Creatine, eGFR, and CRP. This evidence concerns the gene GPT and atrial fibrillation.
