摘要
目的:探讨使用二维超声频谱多普勒技术检测二尖瓣口舒张早、晚期峰值血流速度对不同年龄正常人及高血压患者的左心功能状况判断中的临床意义。方法:使用彩色谱多普勒超声诊断仪检测75例原发性高血压患者及97例正常人二尖瓣口舒张早、晚期峰值血流速度值,计算相关指标并进行对比分析。结果:与正常人年龄呈正相关的指标是A和E/A<1者检出率,与正常人年龄呈负相关的指标是E和E/A比值,E为男性大于女性,A为女性大于男性。A和E/A<1者检出率为高血压患者大于正常人,E/A比值为高血压患者小于正常人,与高血压病程呈正相关的指标是E/A<1者检出率,与高血压病程呈负相关的指标是E/A比值。结论:使用二维超声频谱多普勒技术检测二尖瓣口舒张早、晚期峰值血流速度,对判断高血压患者及不同年龄正常人的左心室舒张及左心房收缩功能状况有明显的敏感性和实用性。
Objective. To study the use of two-dimensional ultrasound doppler for determining left cardiac function of hypertension patients and healthy person by detecting early/late diastolic transmitral flow velocity. Methods. Ultrasound doppler was applied to detect early/late diastolic transmitral flow velocity of 75 primary hypertension patients and 97 healthy person, relevant indicators were compared. Resuits： For healthy person, positive correlation was observed between age and indicator A and the accuracy rate of detecting E/A 〈1, index E and E/A value were negative correlated with age. A and E/A〈1 detection rate for the patients with hypertension was higher than that for healthy person, but opposite result was observed for E/A ratio. For hypertension patients, E/A % 1 was positively correlated with the dis-ease course, while negative correlation was found between disease course and E/A ratio. Conclusions： Two-dimensional ultrasound doppler detection technology is sensitive for detection of left cardiac function of both hypertention patients and healthy person.
