Heart Disease 101: Everything You Need to Know
This article is for people who have heart disease or anyone who wants to learn more about heart disease. The goal of this patient education activity is to understand what causes heart disease and how it can be prevented and treated.
You will learn about:
What causes heart disease?
Who is at risk for a heart attack?
What are the symptoms of a heart attack?
How is heart disease treated?
Questions to ask your doctor

Before you start, please answer this question. At the end of the program, you'll have a chance to answer the question again and then see the correct answer.
What Causes Heart Disease?
A common form of heart disease is when there are blockages from cholesterol and fat build up (called plaque) in the heart arteries. Having blockages limits the amount of blood and oxygen that the heart is getting. Over time, the heart muscle becomes damaged, which can lead to a heart attack.
Also, people with heart disease are at a high risk of getting a blood clot (made of plaque, platelets, and red blood cells) in the heart, which causes a heart attack.
Who Is at Risk for a Heart Attack?
Your chances of having a heart attack are greater if you have these risk factors:
Age 65 years or older
Current smoker
Diabetes
High blood pressure (even with treatment)
High cholesterol (even with treatment)
You get little or no physical activity
Heart failure
Kidney disease
Peripheral artery disease (when plaque builds up in blood vessels in your legs)
Already had a heart attack or stroke
Already had heart surgery
Heart disease runs in your family
What Are the Symptoms of a Heart Attack?
Get medical attention immediately if you have any of these symptoms:
Chest pain or pressure that comes back after rest or moves from your chest to your arms, neck, jaw, or back
Shortness of breath
Stomach pain or nausea
Cold sweat
Feeling very tired
Other symptoms that can happen include: pressure or pain in the lower chest or upper abdomen (stomach), pressure in the upper back, dizziness/fainting, and feeling lightheaded.
How Can I Lower My Risk for a Heart Attack?
For people with heart disease or who have already had a heart attack, it is very important to follow a heart-healthy lifestyle along with taking medicines. There are lifesaving procedures available, as well.
Together, these methods can help treat blockages and heart disease, which helps lower the risk for a heart attack.
What Is a Heart-Healthy Lifestyle?
A heart-healthy lifestyle includes:
Having a heart-healthy diet: Eat more fruits, vegetables, and grains
Maintaining a healthy weight: Lose weight if you are overweight. Have smaller portions to control calorie intake, eat healthy snacks if you get hungry in between meals
Being more physically active: Get at least 20 minutes of exercise, 3 to 4 times a week
Which Medicines Might I Need to Take?
You may need to take several different medicines: for heart-related conditions and possibly 1 or more blood thinners.
Medicines to manage other health conditions: Keep taking medicines as directed for high blood pressure, high cholesterol (eg, a statin), and diabetes, if you have any of those conditions. This can help reduce stress on your heart
Medicines (blood thinners) to lower the risk of a blood clot: A blood thinner can help prevent blood clots from forming and blocking blood flow to the heart. This helps lower the chances for having a heart attack. There are 2 major types of blood thinners: antiplatelet medicines and anticoagulants
Blood Thinners for Heart Disease: Antiplatelet Medicines
Antiplatelet medicines have been used for a long time to treat people with heart disease. These medicines stop blood clots from forming, helping to prevent a heart attack.
After having a first heart attack, your doctor will recommend aspirin. Some people may be taking aspirin with another antiplatelet medicine that is stronger, like clopidogrel, prasugrel, or ticagrelor, after a heart attack or getting a procedure done.
Blood Thinners for Heart Disease: Anticoagulant Medicines
Anticoagulants are a bit newer and work differently than antiplatelet medicines. Anticoagulants slow down the body's process of making blood clots and stop clots from forming in arteries.
These medicines have been used to treat blood clots in the lungs and legs. An anticoagulant, rivaroxaban taken with aspirin, may help prevent a heart attack for people with heart disease.
If the risk of bleeding is low, people with heart disease and those who are at risk for another heart attack may be prescribed an anticoagulant, in addition to other medicines to treat heart disease.
Side Effects of Blood Thinners
Minor bleeding can happen if you are taking a blood thinner.
Serious side effects can also happen, but they are not very common. You should call your doctor if you have:
Serious bruising
Bleeding for a long time from cuts, the gums, or skin when shaving
Nosebleeds that are uncommon or don't stop
Coughing up blood
Blood in vomit or urine
Unusual pain/swelling/discomfort
Severe headache, dizziness/fainting, feeling tired
Trouble swallowing
Procedures for Heart Disease
Surgical or nonsurgical procedures can help improve blood flow to the heart. Procedures that are typically done to prevent or treat a heart attack include:
Balloon angioplasty: A small balloon is inflated inside the blocked heart artery to open it up
Stent placement: A thin mesh tube or "stent" can be placed to permanently keep the heart artery open. This is done at the same time as angioplasty
Bypass surgery: This major surgery connects blood vessels taken from another part of the body to blood vessels around the blocked artery in your heart
Stent Placement in Artery
Questions to Ask Your Doctor
Ask your doctor these questions to find out how you can lower your risk for a heart attack and if a blood thinner may be right for you:
What are my risk factors for a heart attack?
Should I be taking a blood thinner?
What should I do to keep my heart healthy?
When should I get emergency help?
