Title: Relationship between rheumatic heart disease complicated by atrial fibrillation and cardiac structure as well as mean pulmonary artery pressure
Abstract: Objective:To investigate the relationip between rheumatic heart disease complicated by atrial fibrillation(Af) and cardiac ultrasound test results.Method:One hundred and sixteen cases with rheumatic heart disease were divided into Af group(n=64) and sinus rhythm group(n=52),and cardiac ultrasound test results were analyzed statistically before valve replacement.Left atrial diameter(LAD),right atrial dimension(RAD),right ventricular diameter(RVD),left ventricular end-diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),mitral valve area(MO),tricuspid regurgitation(TR),left ventricular septal thickness(IVST),left ventricular posterior wall thickness(PWT),mean pulmonary arterial pressure(mPAP) were measured.Result:Compared with sinus rhythm group,LAD,RAD,RVD,IVST,PWT and mPAP in Af group increased,while LVEDD,MO and LVEF decreased(all P0.05).Single and multiple regression analysis revealed that there was a positive correlation between LAD,mPAP and Af,but a negative correlation between LVEDD,LVEF,MO and Af.Conclusion:Rheumatic heart disease complicated by Af is mainly related to cardiac structural changes and hemodynamic changes.
