Abstract:
Objective To explore the clinical significance of thromboelastography (TEG) in detecting coagulation status in elderly hypertensive patients.Methods A total of 75elderly patients with hypertension, were selected as the elderly hypertensive group.Meanwhile, 60cases of senile cerebral infarction patients and 47cases of normal elderly were selected as the senile cerebral infarction group and the normal elderly group respectively.The values of R, MA, α-Angle, K, CI were measured by TEG-5000thrombus elastometer and then compared in the three groups.Meanwhile, the values of platelet inhibition induced by AA and ADP were also detected in the elderly hypertensive group.The PLT and WBC of the elderly hypertensive group were detected by automatic five class blood cell analyzer.The correlation between TEG parameters and PLT and WBC in elderly hypertensive group were analyzed.Results Compared with the normal elderly group, the MA and CI of the elderly hypertensive group were significantly increased (P＜0.05), theα-Angle and K were significantly decreased (P＜0.05), the R value was not significantly different (P＞0.05), while in the senile cerebral infarction group, the R was significantly shortened (P＜0.05), the CI was significantly increased (P＜0.05) and the K value was significantly decreased (P＜0.05).Compared with the elderly hypertensive group, the R value of the aged cerebral infarction group was shortened (P＜0.05).In the elderly hypertensive group, PLT were negatively correlated with MA, α-Angle and CI, negatively correlated with K value, and not related to R value.WBC was positively correlated with MA, α-Angle and CI, negatively correlated with K value, and low correlation with R value.The proportion of patients ADP inhibition rate≥30％was 41.94％ (13/31), while the proportion of patients AA inhibition rate≥50％was 20.00％ (8/40).Conclusion The detection of TEG is of great significance in helping the clinical diagnosis, treatment guidance and disease monitoring of elderly hypertension, and can prevent the occurrence of complications of hypertension in the elderly hypertensive patients.
