Authors: Shi-feng Li, Ji-hong Shen, Wei Wang, Young-Sheng Wang, Zhong-Jian Li




 

Objective: To explore the diagnostic value of noninvasive cardiac function measurement for masked hypertension.

 

Method: 258 masked hypertension patients were enrolled while 50 healthy persons were served as normal controls.The cardiac function indexes in two groups were measured by noninvasive cardiac function analyzer,such as myocardial contractive force indexes(JP,VP), impedance cardiography indexes(RTM,RS), volume load indexes (GCV, LVDP) and left heart output index(LCI).

 

Results: In all 258 masked hypertension cases ,the myocardial contractive force indexes, impedance cardiography indexes and left heart output index increased unusually,the difference between the two groups was statistically significant, P< 0.05.While the volume load indexes remain unchanged,P<0.05.The myocardial contractive force indexes and the impedance cardiography indexes increased significantly higher than left heart output index, P<0.05.

 

Conclusions: The noninvasive cardiac function measurement has much valuable in the early diagnosis of masked hypertension, especially the myocardial contractive force indexes, impedance cardiography indexes and left heart output index, it appeared to be simple,efficient and worthy to be clinically popularized and applied.
