Adult insomnia associated with heart attack and stroke

"This is probably one of the larger studies published so far on the link between insomnia and cardiovascular risk," says Harvard professor and neurologist Dr. Natalia Rost, head of the stroke department at Massachusetts Hospital in Boston.

"Until we understand the exact connection, what we have learned over the years is that sleep is important," says Rost, who did not participate in the study.

Researchers in a study published in Neurology, a journal of the American Academy of Neurology, asked nearly half a million Chinese about three key symptoms of insomnia:

  • Have you had problems sleeping and sleeping?
  • Did they wake up too early in the morning and couldn't return?
  • And do they have trouble staying focused during the day due to lack of sleep?

Ten years later, researchers examined the cardiovascular health of the study participants. They found that those who had all three symptoms of insomnia were 22% more likely to have coronary artery disease and 1

0% more likely to get a stroke than those who slept well. The finding was made even after the researchers adjusted to confusing factors such as smoking, physical activity levels and alcohol use.

  Wake up, people: you are again mistaken for sleep, study says

Then they analyzed the three insomnia issues separately. Those who report problems staying focused during the day due to poor sleep are 13% more likely to experience heart problems, the study found.

People who report only sleep and sleep problems are 9% more likely, and those who report waking up too early are 7% more likely to develop stroke and heart conditions than people with no sleep problems.

"The relationship between insomnia and symptoms was even stronger in younger adults and people who did not have high blood pressure at the beginning of the study," study author Dr. Liming Li of Beijing said in a statement. University of Beijing.

Future research should be considered especially on early detection and interventions targeting these groups, "added Lee.

A meta-analysis of 2017 of 160,000 people found that those who have difficulty falling asleep, are 27% more likely to receive inf They also found a connection between sleep problems and heart problems, but no connection with early morning waking.

What is the connection?

Science is not sure about the connection. poor sleep quality can alter hormonal function, increase inflammatory processes, or alter metabolism.

"I always think that there are probably more aspects to history than just one connection," says Rost. "Perhaps this is the repair of vessels that we hear more and more about during sleep.

" I also think that insomnia may be a symptom of some other disease in the body that is not yet symptomatic, " said Rost. " Maybe something is already boiling in the body that causes insomnia and ultimately manifests itself 10 years down the road. Hopefully more research will understand the association. "
