ABSTRACT
ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to <5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P<0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P<0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with < 5 years subgroup (F=8.63 and 4.54,P<0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P< 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.
