Changes And Correlation Of Right Ventricle Function With Pulmonary Arterial Systolic Pressure Measured By Echocardiography In Patients With Atrial Fibrillation

Objective Application of real-time three-dimensional ultrasound,tissue doppler ultrasound technology,combined other conventional ultrasonic indicators in patients with atrial fibrillation and atrial fibrillation with pulmonary hypertension patients,we observed right heart function changes,analysed echocardiographic index.To explore the possible relating factors of pulmonary hypertension in patients with atrial fibrillation,the reason of pulmonary hypertension in patients with atrial fibrillation,provide theoretical basis for the treatment and follow-up of patients with atrial fibrillation.Methods A total of 184 patients admitted to the hospital from October 2015 to October 2017 were selected,including 100 males and 84 females,with an average age(59.6 ±14.1years).According to dynamic electrocardiogram and the history of atrial fibrillation,patients were divided into atrial fibrillation group and non-atrial fibrillation group.Blood pressure,blood lipid and blood glucose liver and kidney function were recorded.We measured left and right ventricular atrial size and calculate the left ventricular ejection fraction(LVEF),measured MAD and TAPSE value;E values;Left ventricular Vs and right ventricular Vs and Ve values Tei were measured by TDI.The systolic pressure of pulmonary artery was evaluated comprehensively according to the gradient of tricuspid regurgitation and the collapse rate of the inferior vena cava.Using real-time 3D full-volume echocardiography we measured left and right ventricular end systolic volume(ESV),left and right ventricular end-diastolic volume(EDV).Based on the pulmonary artery systolic blood pressure estimated by echocardiography,patients in atrial fibrillation group were further divided into the normal pulmonary artery pressure group and increased pulmonary artery pressure of atrial fibrillation group,compared the above indicators.Results Compared with non atrial fibrillation group,left atrial enlargement in patients with atrial fibrillation group,MAD and TAPSE reduced,RVEDV and RVESV increased,RVEF reduced significantly.There was no statistically significant difference between the patients' blood pressure,blood lipid and blood glucose.There was no significant difference in the two-dimensional measurement of RVPCA and LVEF.There was no significant difference between the normal group of atrial fibrillation pulmonary artery and the high pressure group of atrial fibrillation.Hypertensive history of patients with atrial fibrillation was higher.Right cardiac function indexes,such as TAPSE RVPCA and tricuspid tissue were significantly reduced.Atrial fibrillation causes decreased right heart function in patients.Left ventricular function indexes,such as LVEF MAD were also decreased.Conclusion Ultrasound technology can accurately evaluate cardiac function changes in patients with atrial fibrillation.In patients with atrial fibrillation,the right cardiac function decreased significantly.Left ventricular diastolic pressure is higher.In atrial fibrillation combined with pulmonary hypertension,the right cardiac function decreased more significantly.Elevated pulmonary arterial pressure was significantly associated with impaired function of left ventricular function.The decrease of right ventricular systolic and diastolic function in atrial fibrillation was closely related to the increased pulmonary arterial pressure.
