Key result
Poor sleep patterns linked to ~141% higher HF risk, alongside increased MI and stroke.
Why the study?
Sleep significantly impacts the incidence of cardiovascular disease, but comprehensive research on this topic is lacking.
Are poor sleep patterns, abnormal sleep duration, and sleep timing associated with an increased prevalence of cardiovascular diseases?

Are poor sleep patterns, abnormal sleep duration, and sleep timing associated with an increased prevalence of cardiovascular diseases?
Poor sleep patterns and abnormal sleep durations are significantly associated with an increased prevalence of cardiovascular diseases, highlighting the importance of sleep hygiene in cardiovascular prevention.

Sleep evaluation may refine CVD risk assessment; leaves open causality and intervention benefits in this observational analysis.
BACKGROUND: Sleep has a significant impact on the incidence of cardiovascular diseases (CVD), but there is no comprehensive research on this topic. AIMS: Assess the association between sleep factors and the risk of cardiovascular diseases in terms of comprehensive sleep behavior. METHODS: This study included 8,075 subjects from NHANES 2017-2020, excluding those with missing sleep/CVD data. Poor sleep factors: abnormal sleep duration (<7h or>8h), trouble sleeping, snoring, snort or stop breathing, sleepy during day. Each factor was scored (0-12 total), classifying sleep patterns as healthy (0-4), intermediate (5-8) or poor (9-12). Multivariable logistic regression analyzed the association between unhealthy sleep and CVD. Weighted data were used for restricted cubic spline (RCS) plots to assess the nonlinear relationship between sleep durations, bedtime, rising time and CVD. RESULTS: Adjusted models showed significant associations between poor sleep and heart failure, myocardial infarction, stroke and hypertension (p < 0.05). Daytime sleepiness also increased stroke and hypertension risks (p < 0.05). RCS plots revealed nonlinear relationships: 7-9 hours sleep/day minimized heart failure, myocardial infarction and hypertension risks; 6-8 hours/day minimized stroke risk. Bedtime showed J-shaped and U-shaped associations with myocardial infarction and hypertension. CONCLUSION: This nationally representative survey revealed that poor sleep patterns, particularly sleep disorders, daytime sleepiness and reported breathing obstructions were significantly associated with an increased prevalence of cardiovascular diseases. Additionally, there was a nonlinear correlation between sleep duration, bedtime, rising time and the risk of developing cardiovascular diseases.

Wang et al. (2025) conducted a cross-sectional in Cardiovascular diseases (n=8,075). Poor sleep pattern vs. Healthy sleep pattern was evaluated on Heart failure (OR 2.41, 95% CI 1.25-4.62, p=<0.05). Poor sleep patterns were associated with an increased risk of heart failure, myocardial infarction, and stroke compared to healthy sleep patterns.
