Chest pain doesn't always signal a heart attack. But that's what emergency room doctors will test for first because it's potentially the most immediate threat to your life. They may also check for life-threatening lung conditions — such as a collapsed lung or a clot in your lung.
Some of the first tests your doctor may order include:
- Electrocardiogram (ECG). This test records the electrical activity of your heart through electrodes attached to your skin. Because injured heart muscle doesn't conduct electrical impulses normally, the ECG may show that you have had or are having a heart attack.
- Blood tests. Your doctor may order blood tests to check for increased levels of certain proteins or enzymes normally found in heart muscle. Damage to heart cells from a heart attack may allow these proteins or enzymes to leak, over a period of hours, into your blood.
- Chest X-ray. An X-ray of your chest allows doctors to check the condition of your lungs and the size and shape of your heart and major blood vessels. A chest X-ray can also reveal lung problems such as pneumonia or a collapsed lung.
- Computerized tomography (CT scan). CT scans can spot a blood clot in your lung (pulmonary embolism) or make sure you're not having aortic dissection.
Depending upon the results from these initial tests, you may need follow-up testing, which may include:
- Echocardiogram. An echocardiogram uses sound waves to produce a video image of your heart in motion. A small device may be passed down your throat to obtain better views of different parts of your heart.
- Computerized tomography (CT scan). Different types of CT scans can be used to check your heart arteries for blockages. A CT coronary angiogram can also be done with dye to check your heart and lung arteries for blockages and other problems.
- Stress tests. These measure how your heart and blood vessels respond to exertion, which may indicate if your chest pain is heart-related. There are many kinds of stress tests. You may be asked to walk on a treadmill or pedal a stationary bike while hooked up to an ECG. Or you may be given a drug intravenously to stimulate your heart in a way similar to exercise.
- Coronary catheterization (angiogram). This test helps doctors identify individual arteries to your heart that may be narrowed or blocked. A liquid dye is injected into the arteries of your heart through a long, thin tube (catheter) that's fed through an artery, either through your wrist or your groin, to arteries in your heart. As the dye fills your arteries, they become visible on X-rays and video.
Treatment varies depending on what's causing your chest pain.
Drugs used to treat some of the most common causes of chest pain include:
- Artery relaxers. Nitroglycerin — usually taken as a tablet under the tongue — relaxes heart arteries, so blood can flow more easily through the narrowed spaces. Some blood pressure medicines also relax and widen blood vessels.
- Aspirin. If doctors suspect that your chest pain is related to your heart, you'll likely be given aspirin.
- Thrombolytic drugs. If you are having a heart attack, you may receive these clot-busting drugs. These work to dissolve the clot that is blocking blood from reaching your heart muscle.
- Blood thinners. If you have a clot in an artery feeding your heart or lungs, you'll be given drugs that inhibit blood clotting to prevent the formation of more clots.
- Acid-suppressing medications. If your chest pain is caused by stomach acid splashing into your esophagus, the doctor may suggest medications that reduce the amount of acid in your stomach.
- Antidepressants. If you're experiencing panic attacks, your doctor may prescribe antidepressants to help control your symptoms. Psychological therapy, such as cognitive behavioral therapy, also might be recommended.
Surgical and other procedures
Procedures to treat some of the most dangerous causes of chest pain include:
- Angioplasty and stent placement. If your chest pain is caused by a blockage in an artery feeding your heart, your doctor will insert a catheter with a balloon on the end into a large blood vessel in your groin, and thread it up to the blockage. Your doctor will inflate the balloon tip to widen the artery, then deflate and remove the catheter. In most cases, a small wire mesh tube (stent) is placed on the outside of the balloon tip of the catheter. When expanded, the stent locks into place to keep the artery open.
- Bypass surgery. During this procedure, surgeons take a blood vessel from another part of your body and use it to create an alternative route for blood to go around the blocked artery.
- Dissection repair. You may need emergency surgery to repair an aortic dissection — a life-threatening condition in which the artery that carries blood from your heart to the rest of your body ruptures.
- Lung reinflation. If you have a collapsed lung, doctors may insert a tube in your chest to reinflate the lung.
Preparing for your appointment
Call for an ambulance or have someone drive you to an emergency room if you experience new or unexplained chest pain or pressure that lasts more than a few moments. Don't waste any time for fear of embarrassment if it's not a heart attack. Even if there's another cause for your chest pain, you need to be seen right away.
What you can do
On the way to the hospital, share the following information with the emergency caregivers:
- Symptoms. Describe your signs and symptoms in detail, noting when they started and anything that makes the pain better or worse.
- Medical history. Have you ever had chest pain before? What caused it? Do you or any close family members have a history of heart disease or diabetes?
- Medications. Having a list of all the medications and supplements you regularly take will be helpful to the emergency workers. You might want to prepare such a list in advance to carry in your wallet or purse.
Once you're at the hospital, it's likely that your medical evaluation will move quickly. Based on results from an electrocardiogram (ECG) and blood tests, your doctor may be able to quickly determine if you are having a heart attack — or give you another explanation for your symptoms. You'll probably have a number of questions at this point. If you haven't received the following information, you may want to ask:
- What's the most likely cause of my chest pain?
- Are there other possible causes for my symptoms or condition?
- What kinds of tests do I need?
- Do I need to be hospitalized?
- What treatments do I need right now?
- Are there any risks associated with these treatments?
- What are the next steps in my diagnosis and treatment?
- I have other medical conditions. How might that affect my treatment?
- Do I need to follow any restrictions after returning home?
- Should I see a specialist?
Don't hesitate to ask additional questions that occur to you during your medical evaluation.
What to expect from the doctor
A doctor who sees you for chest pain may ask:
- When did your symptoms start? Have they gotten worse over time?
- Does your pain radiate to any other parts of your body?
- What words would you use to describe your pain?
- Do you have signs and symptoms other than chest pain, such as trouble breathing, dizziness, lightheadedness or vomiting?
- Do you have high blood pressure? If so, do you take medicine for it?
- Do you or did you smoke? How much?
- Do you use alcohol or caffeine? How much?
- Do you use illegal drugs, such as cocaine?
