We’re all familiar with cardiovascular disease (CVD), but do you know what it is and who it affects?

You might be surprised to learn that new moms are included in the list of those who can be affected by it and that getting enough sleep each night can help reduce your CVD risk.

CVD might seem like a familiar topic, but there’s always plenty more to learn. Here are five surprising facts that might just change how you think about your heart.

CVD vs. Heart Disease

The list below mentions both CVD and heart disease. So quick refresher that cardiovascular disease is the big umbrella term for heart and blood vessel issues, while heart disease is a type of CVD.

1. Young adults aren’t in the clear.

Nearly 50% of Americans age 20 and older have cardiovascular disease — meaning college-age kids are among those with CVD.

“Plaque starts building up in our arteries as early as childhood, so there’s no time like the present to protect your heart,” says cardiologist Navin Natarajan, MD, with Lehigh Valley Heart and Vascular Institute.

2. CVD is hard on new moms.

It’s surprising, but true: CVD is the leading cause of maternal death in the U.S.

Having a baby puts extra strain on the heart, increasing risks during and after pregnancy. Regular checkups during this time are key.

3. Dental problems could hurt your heart.

Research shows that people with poor oral health are more prone to cardiovascular issues, including heart attacks and strokes.

The “why” behind this connection isn’t totally clear. But what matters most is knowing brushing and flossing daily could help your heart, too!

4. Heart attacks can happen without chest pain.

“Sometimes, a heart attack causes discomfort in the back, neck, jaw, arms or area above your belly button,” Dr. Natarajan says. “Other people may only experience shortness of breath, sweating or sudden dizziness.”

5. Sleep is a heart health hero.

Not getting enough z’s can contribute to high blood pressure, obesity and diabetes — three factors linked to heart disease.

To help protect your heart, aim for at least seven hours of slumber each night.

The takeaway: Heart health is complex.

“Talk with your doctor or clinician if you have concerns or want to learn more about your specific risks,” Dr. Natarajan says.
