动态血压监测评估高血压病人左心功能

Ambulatory blood monitoring for assessing the cardiac function in patients with hypertension

采用24小时动态血压监测(ABPM)监测80例轻～中度高血压病人,观察夜间血压升高以及血压负荷>40%对收缩和舒张功能的影响.结果表明:夜间血压升高病人与夜间血压不升高病人比较,E峰最大血流速度(PE)/A峰最大血流速度(PA)及射血分数(EF)均显著降低(P<0.05),左室舒张末期直径增大(P<0.05);24小时收缩期和舒张期负荷>40%与40%比较,左室舒张末期直径增大(P<0.05),PE/PA、EF值显著降低(P<0.05).证实ABPM对高血压病人左心功能评估有一定的意义.

Ambulatory Blood Monitoring was used to assessing the left ventrcular function in 80 patients with mild -to- moderate hypertension in order to observe the influence of elevate asleep SBP and BP load>40% on the left ventricular function. The results revealed that PE/PA and ejection fraction in the patients with elevated asleep BP were lower than those in the patients with the normal asleep BP(P<0. 05). The diamter of the left ventricular end diastolic phsae increased, PE/PA, EF decreased significantly in the patients with≥40% systolic and diastolic load using ambulatory blood monitoring. The results indicated the ABPM played an important role in assessing the left ventricular function in the patients with hypertension.
