[Relationship between different patterns of left ventricular hypertrophy and plasma norepinephrine and hemorheology in patients with essential hypertension].
The changes of plasma norepinephrine (NE) concentration and hemorheology in 60 patients with essential hypertension (EH) with different patterns of left ventricular hypertrophy (LVH) were observed. The results showed that a higher value in whole blood viscosity (WBV) at a shear rate of 230-s was found in concentric hypertrophy (CH) group; a significant increase in plasma NE was found in asymmetric septal hypertrophy (ASH) group. It suggests that CH appear to be a compensation adapting to the increase in afterload. Significant increase in plasma NE concentration may play an important role in the development of ASH in addition to the afterload.
