Does Heart Disease Run in Your Family?

Three generations of menIf you have family members with heart disease,you might be more likely to develop heart disease yourself. Take time to collect your family health history information and share this information with your doctor and other family members. Your doctor can help you take steps to lower your chances of getting heart disease.

Collect and Share Your Family Health History of Heart Disease

Each year in the United States, about 610,000 people die from heart disease. Some medical conditions, such as high cholesterol, high blood pressure, and diabetes, and lifestyle factors, such as an unhealthy diet, lack of exercise, and smoking, can make you more likely to develop heart disease. In addition, having close blood relatives with heart disease can make you more likely to get heart disease.

If you have a family health history of heart disease, collect information on your relatives with heart disease, including what age they were diagnosed. This is especially important if you have a parent, brother, or sister with heart disease. Share this information with your doctor so you can work together on steps to lower your chances of getting heart disease. These steps can include eating a healthy diet, exercising regularly, maintaining a healthy weight, not smoking, limiting your alcohol use, having screening tests done and, in some cases, taking medication.


Rhiannon writes about living with familial hypercholesterolemia.

The Importance of Family Health History: Rhiannon's Story

Rhiannon's father had his first heart attack at age 36 and died from one at age 51. She thought his heart disease was due to his smoking and unhealthy diet, until she got her cholesterol checked at age 30. Her low-density lipoprotein (LDL) cholesterol levels were nearly three times higher than expected for a woman her age. "I had never had my cholesterol checked, because I had always heard that diet and exercise were enough to manage it. It just wasn't supposed to be a problem with someone who is young, active, doesn't smoke and isn't overweight. Right? Wrong. And, boy, was I wrong."

Some people, like Rhiannon, have a common genetic disorder called familial hypercholesterolemia (FH). People with FH have increased levels of LDL cholesterol, which makes them more likely to develop heart disease at a younger age and increases their risk of dying from the disease. For many people with FH, diet and exercise alone are not enough to control their cholesterol levels, and they require medications such as statins. In the United States, about 600,000 people (1 in 500) have FH. Many of them don't know they have it, so they aren't getting the treatment they need. After Rhiannon found out that she had FH, she worried at first, " Would I have a heart attack and die at a young age like my dad?" However, she worked with her doctor to take steps to lower her LDL levels. "I've learned how to manage my cholesterol through medication, diet and exercise. I get my blood [cholesterol] checked regularly… At my most recent check-up, my cholesterol numbers were the best they have ever been."

Finding out that a person has FH not only helps that person, but can help their entire family. Other members of the family can be tested for FH, and those with the disorder can take steps to lower their chances of developing and dying from heart disease. As Rhiannon explains, "I feel extremely fortunate that I found out about my FH before something major happened to me, and I hope to avoid heart disease with prevention."
