Each year, more than 1 million Americans die from heart attacks and other forms of heart disease. Taking low doses of aspirin is one way to help people who are at high risk of or have already had a heart attack or stroke. The most important ways to prevent heart and blood vessel disease is to live a heart-healthy lifestyle. This includes healthy eating, regular exercise, and not smoking. Learn more about how aspirin can help by taking this quiz.
1. One way that aspirin helps people with heart disease is by preventing blood platelets from forming clots.

The correct answer is
Platelets are a type of blood cell. Their sticky surface allows them to begin the process that forms blood clots. Blood clots are important to stop bleeding. But they can also block blood flow to the heart and trigger a heart attack. Or they can block arteries to the brain. This may cause an ischemic stroke, the most common type of stroke. Aspirin makes the platelets less sticky. This lowers the risk for blood clots. If you stop taking aspirin, its effect continues for about 1 week. That's why providers often advise that a person scheduled for surgery or certain procedures stop taking aspirin 1 week before. This lowers the risk of bleeding after surgery or invasive procedures.
2. If you think you're at risk for heart disease, you should take aspirin even if you have not talked with your healthcare provider about it.

The correct answer is
It's important to talk with your healthcare provider about the possible benefits and drawbacks of taking aspirin before you start to take it. Don't take it on your own without first talking with your provider. For most adults who have never had a past heart attack or stroke, it is no longer advised to take aspirin to prevent a first heart attack or stroke. Aspirin may be considered for certain adults ages 40 to 59 who are at a higher risk for heart attack or stroke, but who are not at increased risk for bleeding. Aspirin may be taken if you have had a past heart attack or stroke. Or if you have had coronary artery bypass surgery. It is also used after a procedure called a stent placement. This is when a tiny wire mesh tube, or stent, is placed in an artery to keep it open. Aspirin helps prevent blood clots from forming on the stent. In some people, taking aspirin does pose health risks. These include peptic ulcers, digestive bleeding, and allergic reactions. It can increase the risk for a hemorrhagic stroke. Aspirin also may trigger asthma in some people, especially those who have chronic sinusitis and those with nasal polyps. If you take blood-thinner (anticoagulant) medicine such as warfarin or clopidogrel, aspirin may further raise the risk of bleeding. So it's important that your provider knows if you are taking either or both medicines. Don't start aspirin without your provider's input.
3. As long as you're not allergic to aspirin, aspirin will help protect you against a heart attack.

The correct answer is
Some people may be resistant to aspirin. In these people, aspirin may not give the same protection that it will to those who aren’t resistant. In that case, healthcare providers may prescribe another medicine that helps prevent sticky platelets.
4. If you take a type of blood pressure medicine called an ACE inhibitor, you shouldn't take aspirin.

You answered
The correct answer is
Current research says that aspirin doesn’t affect how ACE inhibitors work. In the past, some health experts thought that aspirin kept ACE inhibitors from working as well as they should. But studies have disproved that. ACE inhibitors lower blood pressure by blocking an enzyme that helps narrow blood vessels. These medicines are often given to people after a heart attack or to people with heart failure.
5. If you have coronary artery bypass surgery, your healthcare provider may start you on aspirin right away.

The correct answer is
Healthcare providers in the past old bypass patients to not take aspirin after surgery. But research suggests that taking aspirin within 48 hours of coronary bypass surgery increases the chance of survival. It also reduces the rate of complications of the heart, brain, kidneys, and digestive tract.
6. Aspirin may help protect blood vessels against inflammation.

The correct answer is
Blood vessels that are affected by atherosclerosis and are narrowed by plaque become inflexible and inflamed. Clinical research has found that aspirin helps prevent blood clots from forming. It also protects the blood vessels against even mild inflammation. Inflammation causes changes in blood vessels similar to those seen in people at high risk for heart disease. Inflammation of the blood vessels also is responsible for angina. Angina is the pain or discomfort in the chest caused when the heart muscle does not get enough blood. Aspirin eases angina by reducing the amount of inflammation-producing chemicals in the body.
7. Aspirin is given to all stroke patients right after arriving at the hospital.

The correct answer is
Most strokes are caused by clots. These are called ischemic strokes. But some strokes are caused by blood vessels that break open (rupture). Taking aspirin could possibly make these bleeding (hemorrhagic) strokes worse. Aspirin may also help to prevent more ischemic strokes, which often happen shortly after the first one. Aspirin given over a long time may also help lower the risk for a second ischemic stroke. But it may raise the risk for a hemorrhagic stroke or bleeding. Aspirin can be combined with other medicines that decrease the stickiness of platelets. An example is ticagrelor. This combo decreases the risk for a second ischemic stroke. The antiplatelet medicines are started within 24 hours of when the stroke symptoms begin.
Antibiotics have been called "wonder drugs," because of their ability to treat bacterial infections that were once deadly. Antibiotics have saved countless lives since they were first introduced 60 years ago. But over use of these drugs has allowed some bacteria to become resistant to them.
Prescription medicines can work wonders when they are taken as they should be. But what happens when you miss a dose? Or when you want to take an over-the-counter medicine along with your prescription? See if you know the answers to these and other questions by taking this quiz.
