高血压合并阵发性房颤患者心脏超声临床特点

目的:观察分析高血压合并阵发性房颤患者的心脏超声特点,为临床准确诊断提供依据。方法:选取2019年08月至2020年08月我院收治的51例高血压合并阵发性房颤患者作为研究组,同时选取51例单纯高血压患者作为常规组,所有患者均接受心脏超声诊断确定有无二尖瓣返流;同时观察心脏收缩期右房上下径、左房前后径、室间隔厚度、舒张期左心室末期内径、左室射血分数、早期二尖瓣血流速度/心房收缩时二尖瓣充盈峰速(Early mitral valve velocity/Mitral valve filling peak velocity during atrial contraction,E/A)。结果:研究组与常规组血压、腰围、BMI指数、血脂、血糖以及血尿素氮无差异(p>0.05);研究组二尖瓣返流病例数多于常规组(P<0.05);研究组E/A、室间隔厚度、收缩期左房前后径均高于常规组(P<0.05),而收缩期右房上下径、舒张期左心室末期内径、左室射血分数无差异(P>0.05)。通过Logistic分析发现,二尖瓣反流、室间隔厚度、收缩期左房前后径与阵发性房颤相关(P<0.05)。结论:高血压合并阵发性房颤的心脏超声特点包括:室间隔厚度增加、左心房扩大、二尖瓣返流等,与单纯高血压差异显著。

Clinical features of echocardiography in hypertensive patients with paroxysmal atrial fibrillation

Objective:To observe and analyze the characteristics of echocardiography in patients with hypertension combined with paroxysmal atrial fibrillation,and to provide basis for accurate clinical diagnosis.Methods:From August 2019 to August 2020,51 patients with hypertension and paroxysmal atrial fibrillation were selected as the study group,At the same time,51 patients with simple hypertension were selected as the routine group,all patients were diagnosed by echocardiography to determine the mitral regurgitation;At the same time,the upper and lower right atrium diameter,left anterior and posterior atrium diameter,ventricular septal thickness,left ventricular end diastolic diameter,left ventricular ejection fraction,Early mitral valve velocity/peak mitral valve filling velocity during atrial contraction(E/A).Results:There were no differences in blood pressure,waist circumference,BMI,blood lipid,blood glucose and blood urea nitrogen between the study group and the control group(p>0.05),The number of mitral regurgitation cases in the study group was higher than that in the conventional group(P<0.05),and the E/A、ventricular septal thickness and the left atrial anteroposterior diameter in systolic period were higher than those in the conventional group(P<0.05),but there was no difference in the upper and lower right atrial diameter,left ventricular end-diastolic diameter and left ventricular ejection fraction(P<0.05).Logistic analysis revealed that mitral regurgitation,ventricular septal thickness,and systolic left anterior and posterior diameter were associated with paroxysmal atrial fibrillation(P<0.05).Conclusion:Hypertension complicated with paroxysmal atrial fibrillation was observed by echocardiography.It was found that the thickness of ventricular septum increased,left atrial enlargement,mitral regurgitation and so on were significant,which was significantly different from that of simple hypertension.
