Adherence
Subjective poor sleep quality is associated with a significant increase in coronary heart disease (CHD) risk, but not with all-cause mortality or other cardiovascular outcomes.
Focus on sleep quality, not just duration. If you frequently report poor sleep quality (restless, disturbed nights), you have a 44% higher risk of coronary heart disease. Address sleep disturbances through sleep hygiene or medical evaluation, as this is a specific risk factor for heart disease.
Subjective poor sleep quality was associated with coronary heart disease (risk ratio, 1.44; 95% confidence interval, 1.09–1.90), but no difference in mortality and other outcomes.
Why this rating
Meta-analysis of 17 studies; subjective measures of sleep quality are less precise than objective measures but still show a significant association.
