Genes affect how we look and how our bodies work, and we inherit them from our parents. Genes can pass on high risk conditions such as high blood pressure and high cholesterol levels. These conditions can increase your risk of developing heart or circulatory diseases.
How does family history affect heart disease?
How do genetics and family history affect the risk of heart disease? When members of a family pass traits from one generation to another through genes, that process is called heredity. Genetic factors likely play some role in high blood pressure, heart disease, and other related conditions.
Will I inherit heart disease if it runs in my family?
Medical conditions that run in a family are inherited or genetic—caused by changes in genes that are passed from generation to generation. Many different types of heart disease can be inherited.
How does heredity affect heart disease?
Inherited genetic mutations can affect the structure of the heart muscle, which can result in symptoms of heart failure. Gene mutations can also affect the heart’s electrical system, which might lead to abnormal heart rhythms.
Does heart disease run in my family?
It’s true that you’re more likely to get heart disease if it runs in your family. Yet it’s only part of the puzzle. “Your genes shouldn’t scare you,” says New York cardiologist Jagat Narula, MD, PhD. “If you take care of the risk factors, you take care of the disease.”
Should I see a cardiologist if I have a family history of heart disease?
“You are at increased risk if you have a parent or sibling with a history of heart disease before age 55 for males or 65 for females,” Dr. Jellis says. If that describes you, she recommends seeing a cardiologist sooner than later.
Can you get heart disease without family history?
It might develop with no symptoms or family history—until you end up in the hospital. Even if you don’t have a family history, the only way to know for sure that your heart is healthy is to get it checked. Heart disease, also called cardiovascular disease, can lead to a heart attack, stroke, or other serious issues.
Can heart conditions skip a generation?
Many cardiac disorders can be inherited, including arrhythmias, congenital heart disease, cardiomyopathy, and high blood cholesterol. Coronary artery disease leading to heart attack, stroke, and heart failure can run in families, indicating inherited genetic risk factors.
What gene causes heart disease?
The scientists combined all their data and came up with six genetic variants that were linked to heart attacks or heart disease. Those variants are in or near the MTHFD1L, PSRC1, MIA3, SMAD3, CDKN2A/CDKN2B, and CXCL12 genes.
