Background: The aim of this study was to investigate the incidence of insomnia after coronary angioplasty and coronary artery bypass graft surgery (CABG) and compare them.
Materials and Methods: This cross-sectional study was done in Masih Daneshvari and Emam Hossein Hospital of Tehran during a period of 12 months in 2016. The study group consisted of patients who were admitted to these hospitals with heart disease and had to go under CABG or angioplasty. Each participant completed a detailed Persian version of the insomnia severity index and demographic questionnaire which includes demographic questions and questions about the onset or durability of sleep as well as questions about the use of alcohol, caffeine, cigarettes, and sleeping drugs 2 days before the surgery and 1 week after that. The state of insomnia was measured before and after the CABG and compared with the state of insomnia before and after angioplasty.
Results: About 150 patients were included in the study (80 men [67.4%] and 70 women [43.6%]). In the CABG group, 14.67% of the preoperative patients and 24.0% of the patients after the operation had insomnia, and the difference between them was significant (P = 0.003). Furthermore, in the angioplasty group, 14.67% of the preoperative patients and 20.0% of the patients after the operation had insomnia, and the difference between them was significant (P = 0.001).
Conclusion: Insomnia after both CABG and angioplasty was significantly increased but in CABG group this increase was more than angioplasty.
