AI Article Synopsis
- - The study aimed to explore the relationship between sleep and coronary heart disease (CHD), focusing on how sleep disturbances can affect patients with both acute coronary syndrome (ACS) and stable CHD, using both objective measurements and self-reports of sleep. - Findings revealed that after experiencing ACS, patients exhibited considerable disruptions in sleep patterns, with recovery taking up to six months; more severe cases of CHD showed greater sleep issues, though results regarding the impact of sleep-disordered breathing and heart function were inconsistent. - The research emphasized a need for future studies to use longitudinal designs and incorporate both objective and self-reported sleep assessments, highlighting that the current studies were mostly low quality and cross-sectional in nature.
Article Abstract
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.
