A study of 3.5 million people found that married couples have the lowest rates of cardiovascular disease.
Dr. Eric Yang of Mayo Clinic says it's not hard to figure out why.
"A lot of people, like myself, say, 'Ah, it's fine, the pain will go away, I don't need to see a doctor.'"
That's a lot harder to do when you have someone at home urging you to get a check-up.
"Men specifically tend to deny that they're having discomfort or think that it will just go away," Dr. Yang says.
Getting to the doctor isn't the only heart health benefit for couples.
Having someone to talk to after a diagnosis can also help lighten the load and lead you to a healthier lifestyle.
While having a primary person at home is one way of keeping your heart in shape, Dr. Yang says having a primary physician is also super important.
"Having a provider who can see you on a regular basis and take care of the issue over time has also been shown to result in better outcomes long-term."
