Abstract
Objective To investigate obstructive sleep apnea syndrome (OSAS) in patients with aortic dissection (AD). Methods Questionnaire analysis was applied to patients with or without AD according to Berlin questionnaire. Questionnaires were collected and common characters and related symptoms were compared between the two groups. Further comparison on related symptoms was made between the AD group and hypertensive patients in the control group. Results Totally 70 questionnaires were collected with 33 for the AD group (29 males and 4 females) and 37 for the control (29 males and 8 females). The average age (P ＜0.05) was 50.9 years for the AD group (range 32 to 70) and 53.4 years for the control (range 25 to 83). Snoring occurred in 29 AD patients (87. 88% ) and in 22 control patients (59. 46% ) (P ＜ 0. 05 ). Snoring everyday occurred in 19 AD patients (57. 58% ) and in 12 controls (32.43%) (P ＜0.05). Loud snoring was reported from 23 AD patients (69.70%) and 10 controls (27.03%) (P ＜0. 05). Apnea occurred in 15 AD patients (45. 45% ) and 8 controls (21.62%) ( P ＜0. 05). Apnea nearly everyday occurred in 9 AD patients ( 27.27% ) and 5 controls ( 13. 51% ) ( P ＜0. 05). Fatigue after sleep occurred in 23 AD patients (69. 70% ) and 15 controls (40. 54% ) (P ＜0. 05).Fatigue nearly everyday after sleep occurred in 10 AD patients (30. 30% ) and 6 controls ( 16. 22% ) ( P ＜0. 05). Hypertension was found in 28 AD patients ( 84. 85% ) and 20 controls ( 54. 05% ) ( P ＜ 0. 05 ).The average age of hypertensive control were 62 ± 16, greater than that of AD group (P ＜0. 05). In the 20 hypertensive control patients, loud snoring in 7 (35%), lessen than that of AD group (P ＜0.05).Compared with hypertensive controls, AD patients had greater body length ( P ＜ 0. 05 ) and lesser waist-tohip ration (P ＜ 0. 05 ). Conclusions Compared with normal control, OSAS is more common in AD patients. Key words: Sleep apnea, obstructive; Aneurysm, dissecting; Hypertension; Questionnaires
