日冕物质抛射引起地磁场变化对稳定型心绞痛患者血液流变学的影响
Influence of the Geomagnetic Activity Caused by Coronal Mass Ejections on Hemorheology in Patients with Stable Angina
摘要
Abstract
Objective To explore the influence of geomagnetic activity caused by coronal mass ejections (CME)on hemorheology in patients with stable angina. Methods We enrolled 162 cases who received inpatient treatment in Department of Cardiology,the First Affiliated Hospital of Kunming Medical University due to chest tightness and chest pain in 2014. According to the coronary heart disease diagnosis standard,they were divided into stable angina group (85 cases)and non-CHD group(77 cases). Hemodynamic indexes including low-shear whole blood viscosity (1. 00 s-1 ),high-shear whole blood viscosity (200. 00 s-1 )and plasma viscosity were measured in both groups before receiving any drug treatment. Based on the geomagnetic activity in Yunnan province in 2014 monitored by Yunnan Observatories,Chinese Academy of Sciences,we defined the period with Dst≤-30 nT as geomagnetic quiet period,and the period with Dst >-30 nT as geomagnetic active period. The variations of hemodynamic indexes in geomagnetic quiet and active periods were compared using the paired test. And the associated factors of hemorheology were investigated by multiple linear regression analysis. Results Geomagnetic activity occurred in 34 days in 2014,with an average annual incidence of 9. 3% . In non-CHD group,both the low-shear and high-shear whole blood viscosity levels were higher in the geomagnetic active period than in the geomagnetic quiet period (P < 0. 05),while the plasma viscosity level changed little (P > 0. 05). In stable angina group,the low-shear and high-shear whole blood viscosity levels were higher in the geomagnetic active period than in the geomagnetic quiet period (P < 0. 05),but the plasma viscosity level varied little (P > 0. 05). Multiple linear regression analysis showed that hyperlipidemia and geomagnetic activity had significant effect on low-shear and high-shear whole blood viscosity (P < 0. 05);hyperlipidemia produced obvious effect on plasma viscosity (P < 0. 05 ). Conclusion Changes in geomagnetic field due to CME can lead to elevated blood viscosity in physiological or pathological conditions.关键词
