Objective:To investigate the current situation of insomnia in patients with acute coronary syndrome (ACS), and analyze the influencing factors of insomnia in the ACS patients, so as to provide information on the development of new strategies for the treatment of insomnia in ACS patients.Methods:This is a multicenter and prospective observational study. A total of 771 ACS patients who met the criteria were selected from March 2013 to June 2015. The baseline social demographic information, sleep quality questionnaire, general anxiety disorder scale-7(GAD-7),patient health questionnaire-9(PHQ-9), short-form 12 health survey questionnaire(SF-12), and enhancing recovery in coronary heart disease patients social inventory(ESSI) were completed within 7 days after admission. Logistic regression analyses were used to analyze the influencing factors of insomnia in ACS patients.Results:A total of 741 subjects with valid questionnaires were collected, including 510 males (68.8%) and 231 females (31.2%). Among them, 487 (65.7%) subjects had at least one insomnia symptom: 308 (41.6%) subjects had difficulty in falling asleep, 369 (49.8%) subjects were easy to wake at night, 116 (15.7%) subjects woke up earlier than they expected, 74 (10.0%) subjects experienced both woke up earlier and difficulty in falling asleep, and 53 (7.2%) subjects woke up earlier, woke up at night and had difficulty in falling asleep at the same time. Logistic regression analyses showed that before admission physical activity ( OR =0.636, 95% CI 0.411-0.984), depression ( OR=1.908, 95% CI 1.101-3.305) and low social support ( OR=0.278, 95% CI 1.198-3.301) were independent factors of insomnia in ACS patients. Conclusions:Nearly 2/3 ACS patients have symptoms of insomnia. Difficulty in falling asleep and easy to wake up at night are the most common manifestations. Physical activity, depression and social support independently are associated with insomnia.
