Insomnia Effects Linked To High Risk Of Heart Disease, Stroke

The people who struggle to sleep at night may face another health problem. A new study suggested that insomnia may increase a person’s risk of heart failure, stroke and coronary artery disease.

The study, published in the journal Circulation, shows the link between cardiovascular problems and the people who are genetically predisposed to insomnia. Researchers said their findings support previous research that found poor sleep contributes to heart conditions and stroke, The Guardian reported Monday

The latest study analyzed 250 genetic variants that all play a role in insomnia. These variants are not available in all people and appear in each person differently. 

“Most people don’t have all of them, people will have a number of them, a few or many of them,” Hugh Markus, study co-author from the University of Cambridge, said. 

The researchers also assessed the cardiovascular condition of nearly 400,000 people who participated in the U.K. Biobank study. Markus and his team found a link between insomnia and poor cardiovascular health. 

“People who suffer from insomnia or disturbed sleep are often at increased risk of coronary heart disease – the leading cause of a heart attack,” Jeremy Pearson, associate medical director at the British Heart Foundation, said. 

The researchers suggested that coronary heart disease increases in people with genetic makeup that cause insomnia. However, the team noted they did not determine how poor sleep directly contributes to poor cardiovascular health. 

They only looked at the genetic predisposition to insomnia and not on how much sleep people had every night during the study. 

“It’s hard to know whether there’s a direct connection or if this is down to other behaviors that are common among people who struggle to sleep, such as a poor diet or living with high blood pressure,” Pearson added. 

But he noted the study still gives an important information. He said if future efforts confirm the connection between insomnia, heart disease and stroke, scientists may create more precise ways for reducing the risk of heart disease.

Markus said there are interventions already available to improve sleep. Previous studies showed that sleep deprivation could negatively affect the body by contributing to health problems such as diabetes, high blood pressure and poor sex drive.
