Tina Turner may have thought love was not good for her heart when she declared, "What's love got to do with it? Who needs a heart, when a heart can be broken?"

But a new study in the Canadian Journal of Cardiology confirms previous findings: When people are recovering from a broken heart (such as heart attack or stroke) or working to manage cardiovascular disease, having a supportive, loving person by their side helps achieve a longer, healthier, happier life.

The doctor-researchers in this latest study urge that all cardio patients be encouraged to bring along a friend, family member, or supporter to appointments, and to have them participate in cardiac rehab programs and lifestyle upgrades.

That will improve the health and quality of life of both people.

Previous studies showed how isolation and loneliness can worsen cardiac outcomes. A review of 34 studies with more than 2 million participants found that single people were 40% more likely to have a heart attack and to die from a heart attack than married people.

Regardless of your current cardio health, it's important to form your posse and reach out to others to reinforce and rekindle friendships. Volunteering also builds connections and fills the heart with emotions (and biochemicals) that promote good health.
