You can take steps today to lower your risk of heart disease and heart attack. Heart disease is the leading cause of death for both men and women in the United States.
To help prevent heart disease, you can:
- Eat healthy and get active.
- Watch your weight.
- Quit smoking and stay away from secondhand smoke.
- Control your cholesterol (“koh-LEHS-tuh-rahl”) and blood pressure.
- If you drink alcohol, drink only in moderation.
- Take steps to prevent type 2 diabetes.
- Manage stress.
Am I at risk for heart disease?
You are at higher risk for heart disease if:
- You are a woman over age 55
- You are a man over age 45
- Your father or brother had heart disease before age 55
- Your mother or sister had heart disease before age 65
As you get older, your risk of heart disease and heart attacks increases. But the good news is that heart disease can be prevented.
What is heart disease?
When people talk about heart disease, they are usually talking about coronary heart disease (CHD). It’s also called coronary artery disease (CAD). This is the most common type of heart disease.
When someone has CHD, the coronary arteries (tubes) that take blood to the heart are narrow or blocked. This happens when cholesterol and fatty material, called plaque (“plak”), build up inside the arteries.
Plaque is caused by:
- Fat and cholesterol in the blood
- High blood pressure
- Too much sugar in the blood (usually because of diabetes)
When plaque blocks an artery, it’s hard for blood to flow to the heart. A blocked artery can cause chest pain or a heart attack.
Learn more about CHD.
What is a heart attack?
A heart attack happens when blood flow to the heart is suddenly blocked. Part of the heart may die if the person doesn’t get help quickly.
Common signs of a heart attack include:
- Chest pain (or a feeling like pressure, squeezing, or fullness)
- Pain or discomfort in the upper body, like the arms, back, neck, jaw, or stomach above the belly button
- Trouble breathing (while resting or being active)
- Feeling sick to your stomach or throwing up
- Feeling dizzy, light-headed, or unusually tired
- Breaking out in a cold sweat
Not everyone who has a heart attack will have all the signs. Learn more about the signs of a heart attack.
Don’t ignore changes in how you feel.
Signs of a heart attack often come on suddenly. But sometimes, they develop slowly – hours, days, or even weeks before a heart attack happens.
Talk to your doctor if you feel tired for several days, or if other health problems (like pain or trouble breathing) bother you more than usual.
Call 911 right away if you or someone else might be having a heart attack.
Don’t ignore any signs or feel embarrassed to call for help. Acting fast can save a life. Call 911 even if you are not sure it’s a heart attack.
An ambulance is the best and safest way to get to the hospital. In an ambulance, EMTs (emergency medical technicians) can check how you are doing and start life-saving medicines and other treatments right away.
People who call an ambulance often get treated faster at the hospital. And, if you call 911, the operator can tell you what to do until the ambulance gets there.
