Abstract:
OBJECTIVETo observe blood flow features in elderly hypertension patients of different Chinese medical syndrome types and to test their correlation with rheological properties of red blood cells (RBCs) by applying micro-channel array flow analyzer (MC-FAN).
METHODSRecruited were 109 elderly hypertension patients were assigned to phlegm-stasis blocking collateral group (35 cases), yin deficiency yang hyperactivity group (42 cases), Shen deficiency group (32 cases) according to Chinese medical syndrome typing. Besides, another 21 elderly healthy subjects were recruited as the control group. The hemorheology visualization testing of elderly hypertension patients was detected using MC-FAN. The erythrocyte deformation index (DI), erythrocyte aggregation index (EAI), and erythrocyte related plasma ATPase activity were observed. The correlation between the transiting time (TT) of blood hemorheology visualization and rheological indicators of RBCs were analyzed.
RESULTSThe hemorheology visualization TT was significantly prolonged more in the phlegm-stasis blocking collateral group than in the yin deficiency yang hyperactivity group, the Shen deficiency group, and the control group (P < 0.05). Compared with the control group, the DI was significantly lower in the phlegm-stasis blocking collateral group than in the yin deficiency yang hyperactivity group, the Shen deficiency group, and the control group (P < 0.05) when the shear rate was 100 s(-1). Compared with the control group, the plasma Na+ -K(+) -ATPase activity and the plasma Ca2+ -Mg2+ -ATPase activity were significantly lower in elderly hypertension patients (P < 0.01). Among the three groups, plasma Ca2+ -Mg2+ -ATPase activity was significantly lower in the phlegm stasis blocking collateral group than in the Shen deficiency group (P < 0. 05). The hemorheology visualization TT (10, 30, 60, and 100 microL) was negatively correlated with DI. The hemorheology visualization TT at 100 microL was positively correlated with EAI.
CONCLUSIONChanges of hemorheology visualization TT of elderly hypertension patients were significant and correlated with traditional EAI.
