Adults with healthy sleep patterns had a 42 per cent lower
risk of heart failure regardless of other factors when compared to those with
unhealthy sleep patterns, according to a new study.
An observational research published in the American Heart Association’s
flagship journal Circulation examined
the relationship between healthy sleep patterns and heart failure. A total of 408,802
participants aged 37 to 73 at the time of recruitment (2006-2010) were
monitored and the incidence of heart failure collected until April 1, 2019.
Researchers recorded 5,221 cases of heart failure during a median follow-up of
“The healthy sleep score we created was based on the scoring
of five sleep behaviours. Our findings highlight the importance of improving
overall sleep patterns to help prevent heart failure," said Lu Qi, corresponding
author and professor of epidemiology and director of the Obesity Research
Center at Tulane University in New Orleans.
Researchers analyzed sleep quality as well as overall sleep
patterns. The measures of sleep quality included sleep duration, insomnia and
snoring and other sleep-related features, such as whether the participant was
an early bird or night owl and if they had any daytime sleepiness (likely to
unintentionally doze off or fall asleep during the daytime).
Sleep behaviours were collected through touchscreen
questionnaires. Sleep duration was defined into three groups: short, or less
than 7 hours a day; recommended, or 7 to 8 hours a day; and prolonged, or 9
hours or more a day.
After adjusting for diabetes, hypertension, medication use,
genetic variations and other covariates, participants with the healthiest sleep
pattern had a 42% reduction in the risk of heart failure compared to people
with an unhealthy sleep pattern.
Healthy sleep patterns include habits like rising in the morning, sleeping 7-8 hours a day and no excessive daytime sleepiness.
