Comparative analysis of subjective and objective sleep quality in post-stroke insomnia

Objective To investigate the differences in objective and subjective sleep quality in post- ischemic stroke insomnia,and the possible influencing factors. Methods In cardiovascular hospital affiliated to Ningxia Medical College,42 patients of post-stroke insomnia as case group and 16 normal controls were recruited,which were measured with Pittsburgh Pittsburgh Sleep Quality Index( PSQI) and poloysomnography( PSG) in Jun. 2012 to Apr. 2014,and the next day followed by SAS and SDS. Results Compared with the healthy controls,sleep latency for insomnia in ischemic stroke prolonged( 80. 5 ± 49. 3) min,total sleep duration decreased( 267. 00 ±38. 16) min,sleep efficiency lowed( 50. 77 ±7. 97) %,awake frequency increased. PSG founds Shallow sleep increased and deep sleep decreased in insomnia of ischemic stroke. The sleep latency,total sleep time and sleep efficiency acquired from subjective estimation were different with the results of polysomnography,in insomnia of ischemic stroke and sleep- related breathing disorder( P 0. 05).Sleep latency difference between subject and object view had positive correlation with anxiety and depression scores( r = 0. 13,P 0. 05),and sleep efficiency difference had positive correlation with anxiety scores( r = 0. 41,P 0. 05). Conclusion Subjective and objective assessment of quality of sleep in post- ischemic stroke insomnia have significant differences may be related to an increased in light sleep,awakening times,rousal,and related to depression,anxiety and so on.
