Adults with the healthiest sleep patterns (those who wake up in the morning, sleeping 7 to 8 hours a day without frequent insomnia) experienced a 42% reduction in the risk of heart failure compared to those with sleep patterns unhealthy.
And this remains the case regardless of other risk factors, according to new research published by the American Heart Association in the journal Circulation.
Heart failure affects more than 26 million people, and emerging evidence indicates that sleep problems may play a role in the development of heart failure.
This observational study described healthy sleep patterns such as getting up early in the morning, sleeping 7-8 hours a day, and not having frequent insomnia, snoring, or excessive daytime sleepiness.
It included data on 408,802 UK participants, aged 37 to 73, who were recruited between 2006 and 2010. The incidence of heart failure was collected through 2019, and the researchers recorded 5,221 cases of heart failure during a median follow-up of 10 years. .
After collecting data via touch-screen questionnaires, the researchers analyzed sleep quality and general sleep patterns, including whether the participant was a night owl and whether they were likely to fall asleep involuntarily or fall asleep during the day.
“The healthy sleep score we created was based on the scores for these five sleep behaviors,” said Lu Qi, MD, Ph.D., Corresponding Author and professor of epidemiology and director of the Tulane University Obesity Research Center in New Orleans. “Our findings highlight the importance of improving general sleep patterns to help prevent heart failure.”
After adjusting for diabetes, hypertension, drug use, genetic variations, and other covariates, participants with the healthiest sleep pattern had a 42% reduction in risk of heart failure compared to those with poor sleep patterns. healthy.
They also found that the risk of heart failure was independently associated and:
8% lower in early risers;
12% less in those who slept 7 to 8 hours a day;
17% lower in those who did not have frequent insomnia; Y
34% fewer in those who reported no daytime sleepiness.
The researchers noted that other unknown or unmeasured settings may also have influenced the findings, but the strengths of the study include its novelty, prospective study design, and large sample size.
Funding came from the National Heart, Lung, and Blood Institute; and the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health, along with the Boston Obesity Nutrition Research Center.
