【摘要】：目的：探讨高血压病患者左心室舒张功能与动态血压参数的相关性。方法：入选原发性高血压患者137例,询问病史、体检并采用超声心动图测量收缩末期左、右心房内径、左心室舒张末期内径(LVEDD)、左心室射血分数(LVEF)。左心室舒张功能测定用二尖瓣舒张早期血流峰值速度/舒张晚期血流峰值速度(E/A)值,以评价左室舒张功能。根据E/A值的大小将原发性高血压患者分为两组,E/A≥1组视为左心室舒张功能正常组(n=54例),E/A1为左心室舒张功能不全组(n=83例)。患者均行24h动态血压及血生化检测。结果：左心室舒张功能不全组的24h平均收缩压明显高于功能正常组(P0.05),并且具有显著正相关。结论：高血压病患者左心室舒张功能与动态血压参数有关联。
[Abstract]:Objective: To investigate the correlation between left ventricular diastolic function and ambulatory blood pressure in patients with hypertension. Methods: 137 patients with essential hypertension were asked for medical history and physical examination. Echocardiography was used to measure systolic and left atrial diameter, left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF). The left ventricular diastolic function was measured by the peak velocity of the early diastolic blood flow / late diastolic peak velocity (E/A) in the left ventricular diastolic function in order to evaluate the left ventricular diastolic function. According to the size of the E/A value in patients with primary hypertension were divided into two groups, E/A = 1 group were regarded as normal left ventricular diastolic function group (n=54 cases), E/A1 for left ventricular diastolic dysfunction group (n=83 cases). 24h ambulatory blood pressure and blood biochemical test were performed in all patients. Results: the mean 24h systolic pressure in the left ventricular diastolic dysfunction group was significantly higher than that of the normal functional group (P0.05), and had a significant positive correlation. Conclusion: left ventricular diastolic function is associated with ambulatory blood pressure parameters in patients with hypertension.
