摘要
目的 :探讨老年高血压病并发冠心病患者的自主神经活动特点。方法 : 对 5 9例原发性高血压 (EH)、5 4例冠心病 (CHD)和 38例 EH并发 CHD患者与 34例健康老年人的心率变异性 (HRV)进行对比研究。结果 :EH组和CHD组与对照组除 EH组的 R- R间期标准差的平均数 (SDNNIndex)外 ,其余参数差异均有显著性 (P<0 .0 5 ) ;EH并发 CHD组与对照组比较 ,参数差异均有非常显著意义 (P<0 .0 1) ;但不同疾病组间比较 ,差异均无显著性 (P>0 .0 5 )。结论 :高血压病和冠心病患者的自主神经功能受损 ,当高血压病并发冠心病时这种受损更加明显。其迷走神经张力降低 ,交感神经紧张性相对增高是导致老年患者心率变异性降低的主要原因。
AIM:To study autonomic nerve regulator character in elderly patients with essential hypertension (EH) and coronary heart disease (CHD). METHODS:The heart rate variability (HRV) in 59 EH,54 CHD,38 EH+CHD patients and 34 healthy elderly subjects were investigated. RESULTS:Except the SDNN Index of EH there were significant difference between HRV in the patients with EH,CHD and healthy elderly subjects( P <0.05), There were much significant difference bwtween HRV in the patients with EH+CHD and healthy elderly subjects( P <0.01),but no significant difference between HRV in the patients with EH and CHD ( P >0.05). CONCLUSON:The autonomic never function of EH and CHD patients are damaged,and the EH+CHD patients is the most. The vagal hypoactivity and sympathetic hyperactivity were major causes of reduction of HRV in the elderly patients.
