本文对20例老年和11例中年急性脑梗塞患者血液流变学中6项指标进行24小时动态观察,并对41例老年急性脑梗塞患者发病时间进行调查。结果表明,血流变学6项指标均在早8:00时呈高峰值、凌晨2:00时呈较高峰值,与41例老年急性脑梗塞患者的发病时间多在清晨前后相吻合。其中纤维蛋白原也同血液流变学中其他5项指标呈24小时周期节律性变化;早8:00时的日高峰值与低谷值相比,全血(还原)粘度、红细胞压积有显著差异(P<0.05);6项指标老年组均低于中年组,但无显著性差异(P>0.05)。提示血液流变学6项指标早8:00时高峰值和凌晨2:00时的较高峰值与急性脑梗塞的发生有关。
In this paper, six indicators of hemorheology in 20 elderly patients and 11 middle-aged acute cerebral infarction patients were observed for 24 hours. The onset time of 41 elderly patients with acute cerebral infarction was investigated. The results showed that all the six indexes of hemorrheology peaked at 8:00 AM and peaked at 2:00 AM, which was consistent with the onset time of 41 elderly patients with acute cerebral infarction before and after the morning. Among them, fibrinogen also had a rhythmical change of 24 hours with the other five indexes in hemorheology. Compared with the lowest value, the peak of the daily blood viscosity and the hematocrit of 8:00 were significantly (P <0.05). The 6 indicators in the elderly group were lower than those in the middle-aged group, but there was no significant difference (P> 0.05). Tip 6 indicators of hemorheology as early as 8:00 am peak and 2:00 am when the peak is associated with the occurrence of acute cerebral infarction.
