While the relationship between osa and increased cardioascular morbidity and mortality is well - known , this is the first study to examine the association between daytime sleepiness and cardiac hemodynamic performance in patients without established cardioascular disease 雖然阻塞性睡眠呼吸暫停與心血管病的發病率和死亡率的增加的關系已經眾所周知,這個實驗第一次在未確診有心血管疾病的患者中研究白天嗜睡與心臟血流動力學表現二者之間的關系。

Howeer , when we measured their cardiac output we found those with greater daytime sleepiness scores had a more aderse hemodynamic profile than those with sleep apnea who were less affected by daytime sleepiness , “ he said 但是當我們測量他們的心排出量時我們發現那些白天嗜睡得分較高的病人和那些患有睡眠呼吸暫停但是被白天嗜睡影響較小的病人相比,有著更加不利的血流動力學狀態。 ”

The authors conclude that adults plagued by excessive daytime sleepiness should be thoroughly evaluated for depression and diabetes , regardless of whether or not sleep - disordered breathing is present 研究人員在考慮到很多能引起人們日間極度嗜睡的原因后發現,與睡眠呼吸紊亂或睡眠中斷相比,日間極度嗜睡和抑郁癥、肥胖或新陳代謝等因素具有更為緊密的聯系。
