Title: Impact of atrial fibrillation on echocardiographic indices of hypertensive patients and their relationship with the development with atrial fibrillation.
Abstract: Objective To investigate the differences of echocardiographic indices between the hypertensive patients with and without AF.To explore the relationship of these indices with the development of AF in hypertensive patients.Methods Totally 41 hypertensive patients with AF and 45 sex-,age-and risk factors-matched hypertensive patients without AF were enrolled.The age for the two groups was 59.6±11.4 and 57.1±9.2 years old,respectively.All patients underwent transthoracic echocardiography assessment of left atrial anterior-posterior dimension(Lad),right atrial upper-inferior dimension(Rad),interventricle septum dimension(IVSd),left ventricular diameter(LVIDd),left ventricular ejection fraction(LVEF) and qualitative assessment of mitrial regurgitation(MR).Results Hypertensive patients with AF had higher Lad and IVSd(Lad: 36.1±5.8vs 31.0±3.9mm,P0.001;IVSd: 10.7±1.3vs 44.0±4.0mm,P=0.001),and higher MR incidence(52.5%vs 11.1%,P0.001) compared with those without AF.No significant differences in Rad,LVIDd and LVEF were found between the two groups.By multivariable analysis,Lad,IVSd and MR incidence were founded to be independent risk factor of AF development in hypertensive patients with theOR(95%CI) being 1.375(1.135~1.665),1.98(1.183~3.313) and 4.708(1.126~19.685),respectively.Conclusion The combination of AF contributes to increase of Lad,IVSd and MR incidence,each of which was associated with the development of AF in hypertensive patients.
