Heart Attack or Cardiac Arrest?
5 Differences Between a Heart Attack and a Cardiac Arrest
A heart attack is not the same as a cardiac arrest.
A heart attack is when one of the coronary arteries becomes blocked. The heart muscle is robbed of its vital blood supply and, if left untreated, will begin to die because it is not getting enough oxygen.
A cardiac arrest is when a person’s heart stops pumping blood around their body, and they stop breathing normally.
Many cardiac arrests in adults happen because of a heart attack. This is because a person who is having a heart attack may develop a dangerous heart rhythm, which can cause cardiac arrest.
A heart attack and a cardiac arrest are both emergencies. Call 999 straight away.
Heart Attack Awareness
A heart attack is heart damage caused by reduced or blocked blood flow to the heart muscle. Another name for the condition is myocardial infarction. A heart attack is a medical emergency. First aid for a heart attack includes cardiopulmonary resuscitation (CPR). It can help save a person’s life.
When to Seek Emergency Help
Call 911 or emergency medical help if you think you or someone else might be having a heart attack.
Symptoms
Symptoms of a heart attack may include:
- Chest pain that may feel like pressure, tightness, pain, squeezing or aching.
- Pain or discomfort that spreads to the shoulder, arm, back, neck, jaw, teeth or sometimes the upper belly.
- Cold sweats.
- Fatigue.
- Heartburn or indigestion.
- Light-headedness or sudden dizziness.
- Nausea.
- Shortness of breath.
A heart attack usually causes chest pain that lasts more than 15 minutes. The chest pain may be mild or severe. Some people don’t have any chest pain or pressure.
Symptoms may be less obvious in some people, especially for women. For example, heart attack symptoms may include nausea, or a brief or sharp pain felt in the neck, arm, or back.
Some heart attacks happen suddenly. But many people have warning signs hours or days in advance.
Treatment
- Call 911 or your local emergency number. Don’t ignore the symptoms of a heart attack. If you can’t get an ambulance or emergency vehicle to come to you, have someone drive you to the nearest hospital. Drive yourself only if you have no other option.
- Take aspirin, if recommended. Aspirin helps prevent blood clotting. Taking aspirin during a heart attack may reduce heart damage. Don’t take an aspirin unless a healthcare professional says to do so. Don’t delay calling 911 to take an aspirin. Call for emergency help first.
- Take nitroglycerine, if prescribed. If you think you’re having a heart attack and you have a prescription for this medicine, take it as directed while waiting for emergency medical help.
- Start CPR if the person doesn’t have a pulse or isn’t breathing. If you’re untrained in CPR, do hands-only CPR. That means push hard and fast on the person’s chest. Do this about 100 to 120 times a minute. If you’re trained in CPR and confident in your ability, start with 30 chest compressions before giving two rescue breaths.
- Use an automated external defibrillator (AED) if one is available and the person is unconscious. The device delivers shocks to reset the heart rhythm. AEDs come with step-by-step voice instructions for their use. They’re programmed to allow a shock only when appropriate.
Prevention
Lifestyle changes can keep the heart healthy and may help prevent a heart attack:
- Don’t smoke or use tobacco.
- Get regular exercise.
- Keep a healthy weight.
- Eat nutritious foods and use less salt and saturated fats.
- Limit alcohol.
- Manage stress.
- Control blood pressure, blood sugar, and cholesterol.
- Get 7 to 8 hours of sleep daily.
Also, it’s a good idea to learn CPR and how to use an AED so you can help someone who’s having a heart attack. Ask your healthcare team if any accredited first-aid training courses are available in your area.
