Knowing what causes heart disease and how you can prevent it can help you live a longer, healthier life. Take this quiz to find out more about lowering your risk for heart disease.
1. There's nothing you can do to prevent heart disease.
You didn't answer this question.
You answered
The correct answer is
Healthy adults can reduce their risk for heart disease and a heart attack by:
Staying at a healthy weight. This means a body mass index of less than 25.
Getting enough exercise. This means 150 minutes of moderate-intensity physical activity each week. Or 75 minutes of vigorous-intensity activity.
Having regular medical checkups
Taking prescribed medicines
Choosing healthy habits. For example, not smoking, not drinking too much alcohol, and controlling stress.
Meet with your healthcare provider at least once a year, or more often if you have health concerns. This is to make sure you are on top of your health and heart disease prevention.
2. Smokers are more likely to have heart disease than nonsmokers.
You didn't answer this question.
You answered
The correct answer is
Smokers who smoke 1 pack per day are more than twice as likely as nonsmokers to have a heart attack. Smoking is one of the strongest preventable risk factors for heart disease. Talk with your doctor today about how to quit.
3. Some risk factors for heart disease can't be changed.
You didn't answer this question.
You answered
The correct answer is
They include gender (adults assigned male at birth have a higher risk for early heart attack), age (your risk of heart attack increases as you get older), and family (you have an increased risk if your father or mother had heart disease). These are out of your control, but making changes to your lifestyle is a big part of preventing heart disease.
4. You have to exercise at least 1 hour a day to reduce your risk for heart disease.
You didn't answer this question.
You answered
The correct answer is
Getting 150 minutes of moderate-intensity physical activity each week is tied to good health. This can also help you reduce your risk for heart disease. This physical activity can be done in 30- to 40-minute chunks on most days of the week. Good choices are walking, cycling, and swimming. You can also choose activities you enjoy such as dancing and aerobics.
5. Drinking 3 to 4 alcoholic drinks each day can reduce your risk for heart disease.
You didn't answer this question.
You answered
The correct answer is
Adults assigned male at birth should not have more than 2 drinks a day. Adults assigned female at birth should limit themselves to 1 drink a day. If you do not already drink, you should not start drinking in order to lower your risk for heart disease. Other lifestyle changes can help with that.
6. High blood pressure can put your heart at risk.
You didn't answer this question.
You answered
The correct answer is
Your heart must work harder than normal when your blood pressure is high. When this occurs over a long time, the heart can enlarge and arteries can become scarred and hardened. This can lead to increased risk for heart disease and even a heart attack.
7. An average of 100,000 Americans die from heart disease every year.
You didn't answer this question.
You answered
The correct answer is
Nearly half of all adults in the U.S. have some form of cardiovascular disease. This includes heart disease, heart failure, stroke, and high blood pressure. More than 500,000 deaths each year are related to cardiovascular disease. More people die from cardiovascular disease than from all cancers and chronic lung disease combined.
8. Someone who has had a heart attack is at increased risk of having another.
You didn't answer this question.
You answered
The correct answer is
Some people ages 45 and older who survive a first heart attack are at increased risk of having another heart attack in the next 5 years.
9. You can't exercise if you have heart disease.
You didn't answer this question.
You answered
The correct answer is
Moderate exercise approved by your healthcare provider plays an important role in controlling the disease. Talk with your provider about an exercise plan that is right for you. You may need to be in a cardiac rehab (rehabilitation) program if you have already had a heart attack.
10. Being overweight increases your risk for heart disease.
You didn't answer this question.
You answered
The correct answer is
Your risk increases if you're overweight. This is because being overweight increases your risk for high blood pressure, diabetes, and high cholesterol. These conditions also increase the risk for heart disease.
11. Young adults assigned female at birth have the same risk for heart disease as young people assigned male at birth.
You didn't answer this question.
You answered
The correct answer is
Estrogen provides younger adults assigned female at birth some protection against heart disease. But that protection is lost after menopause, when those adults have roughly the same risk as adults assigned male at birth.
12. Emotions don't affect your risk for heart disease.
You didn't answer this question.
You answered
The correct answer is
Research shows a link between heart disease and high levels of stress and hostility. Stress increases hormone levels. These put higher demands on the heart.
13. Your diet doesn't affect your risk for heart disease.
You didn't answer this question.
You answered
The correct answer is
The food you eat has a direct impact on 3 major risk factors for heart disease: weight, blood pressure, and blood cholesterol. It's important to understand the relationship that these all have to prevent heart disease. Talk with your healthcare provider if you have questions.
14. No tests can diagnose coronary heart disease.
You didn't answer this question.
You answered
The correct answer is
A treadmill test (or exercise stress test) can help diagnose atherosclerosis, or the narrowing of the heart's arteries. Other tests include a radionucleotide myocardial perfusion stress test and CT scan. These can also help diagnose a narrowing of the arteries in your heart. But the gold standard test is a cardiac catheterization (coronary angiogram). This test lets your healthcare provider see any blockages in your heart's arteries.

A coronary calcium scan is a test that looks at the arteries that supply blood to the heart muscle. These are called the coronary arteries. The scan checks for plaque buildup along the walls of these arteries.
A contrast echocardiogram helps your health care provider see how your heart is working. It uses ultrasound and a contrast fluid to help highlight the structures in the heart.
