“…A cross-sectional study in 2017 on prevalence and determinants of insomnia after a MI among 209 subjects was conducted by Da Costa et al The findings showed that overall 36% of the sample reported clinical symptoms of insomnia. Among the patients after MI, 62.7% subjects which was a higher proportion were experiencing insomnia with depressed mood when compared to good sleepers (13.4%) [12]. This reported study findings support the present study, indicating that insomnia is a major concern of sleep disturbances among CVD patients.…”

Objective: This was a descriptive study with the objective to determine the sleep disturbances and the quality of sleep among patients with cardiovascular diseases (CVDs). Methods:Quantitative approach with non-experimental descriptive design was used. A semi-structured sleep disturbance questionnaire was used to determine the sleep disturbances, and a standardized Pittsburgh Sleep Quality Index tool was used to assess the sleep quality among 100 subjects in Amrita Institute of Medical Sciences, Kochi. Results:The study results showed that majority of the subjects (51%) were of the age group between 56 and 65 years, and 71% were male with CVD. Sleep disturbances were present in 80% of the subjects with CVD, among which 56% subjects had mild disturbances, 20% subjects with moderate sleep disturbances, and 4% subjects with severe sleep disturbances. The result also indicated that 48% of subjects had poor sleep quality. Findings also showed a highly statistically significant association between cardiomyopathy and sleep disturbances (p<0.001). Total cholesterol and low-density cholesterol levels were significantly associated with sleep disturbances (p<0.05). There is a highly significant association between sleep disturbances and quality of sleep (p<0.001), indicating that sleep disturbances can be one factor in decreasing the quality of sleep in patients with CVD. Conclusion:The results of the study indicated that sleep disturbances were prevalent in patients with CVD and often hazardous to heart health. As health practitioner and other health-care providers have not focused major attention on the importance of sleep to health, the need for providing information to them and patients regarding the importance of improving the quality of sleep and identifying the sleep disturbances will call for action to bring sleep to the forefront of public health.

“…75 Furthermore, literature within the current review reported worse self-reported sleep being associated with more prevalent depressive symptoms and antidepressant usage. 46,48 The relationship between insomnia and depression is bidirectional, 76 and treatment of insomnia in spite of comorbid conditions (eg, depression) should be undertaken. 77,78 Treatment of comorbid insomnia and depressive symptoms have shown a faster remission from depression.…”

Study Objectives: Investigation into sleep and coronary heart disease (CHD) has predominantly been focused on sleep disturbances as a risk factor for developing CHD. Objectively measured and self-reported sleep at a patient level has only been sparsely and not systematically reported. Therefore, we set out to review the literature for studies using objectively measured and self-reported sleep in patients with CHD. The review focuses on patients with acute coronary syndrome (ACS) and stable CHD. Methods: A systematic review performed in four databases adhering to the PRISMA guidelines applying a qualitative synthesis of evidence. Results: Following ACS, we found sleep architecture to be significantly disturbed with changes normalizing over a period of up to 6 months. With increasing severity of CHD, sleep disturbances were more pronounced; however, the modulating effects of sleep-disordered breathing and ejection fraction on sleep in patients with CHD are conflicting. Overall, studies were predominantly cross-sectional in design and of low methodological quality. Polysomnography was the predominant outcome assessment tool and validated self-reported assessment tools were limited. Conclusions: Future investigations in sleep and CHD applying both a longitudinal design and investigating objective and self-reported sleep assessments are warranted.

“…The findings suggests for evaluating cognitive-behavioral approaches for the management of insomnia in patients after MI. 13 The findings indicate that β-blockers decrease melatonin release via specific inhibition of adrenergic β1-receptors. Since lower nocturnal melatonin levels might be the reason for sleep disturbances.…”
