Be prepared and sign up for a first aid course today!"],"attrs_boilerpipe_text":"A heart attack happens when blood supply to part of the heart muscle is blocked. Because the cells in the affected area of the heart muscle are not receiving the oxygen and nutrients they need, they become damaged and can die, causing the heart to not pump normally and if untreated, stop pumping blood. Calling 9-1-1 as soon as you recognize the signs and symptoms of a heart attack can minimize the damage to the heart and may save the person’s life.\nSigns and symptoms of a heart attack vary from person to person and can be different in women than they are in men. Even people who have had a heart attack before may not experience the same signs and symptoms if they have a second heart attack. The signs and symptoms of a heart attack may also be more subtle in people with certain medical conditions, such as diabetes. If you suspect a heart attack, always respond as if it is one. Although men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or\nvomiting\n; extreme fatigue; and dizziness or light-headedness.\nHave them stop activity and rest in a comfortable position.\nIf they are awake, can understand simple commands, and can chew or swallow and are allowed to have aspirin, assist them to take two to four low-dose (81-mg) aspirin tablets (162 to 324 mg) or one regular-strength (325-mg) aspirin tablet.\nIf they have prescribed medication such as nitroglycerin, offer to assist with taking it.\nLoosen tight or uncomfortable clothing.\nContinue checking them as appropriate to determine if additional care is needed.\nKeep person from getting cold or overheated.\nGive care for shock, if necessary.\nStay with them until EMS arrives.\nReassure person you will help and that EMS has been called (if appropriate).\nWatch for changes in condition, including breathing and responsiveness until EMS arrives, and give care as appropriate and trained.\nBe prepared to give CPR or compression-only CPR based on level of training and use an AED when available if they become unresponsive and are not breathing (cardiac arrest).\nWhat are some tips to help save the life of a person with a heart attack?\nCall 9-1-1 immediately if you think someone is having a heart attack.\nGet or instruct someone to get an AED if there is one available.\nNever drive a person to the hospital yourself.\nDon’t delay seeking care by disregarding signs and symptoms.\nDon’t worry about causing a “false alarm” by calling 9-1-1.\nRemember: Most people that succumb to fatal heart attacks die within the first 2 hours of signs and symptoms. Early care saves lives.\nI’ve heard that women may have different symptoms of a heart attack than men. Is this true?\nAlthough men often have “classic” signs and symptoms of a heart attack, such as chest pain radiating down one arm, women may have more subtle signs and symptoms or experience a heart attack differently than men do.\nFor example, the “classic” signs and symptoms in women may be milder or accompanied by more general signs and symptoms such as back pain, shortness of breath, nausea or vomiting, extreme fatigue, and dizziness or light-headedness. Because these signs and symptoms are general and nonspecific, women may experience them for hours, days or even weeks leading up to the heart attack but dismiss them as nothing out of the ordinary.\nDifference Between Heart Attack and Cardiac Arrest\nA heart attack and cardiac arrest are not the same thing. A heart attack is a blockage of the blood vessels that supply oxygen to the heart muscle. The person may be awake, and if left untreated the heart attack may progress to cardiac arrest. Cardiac arrest is when the heart stops beating or beats too ineffectively to circulate blood to the brain and other vital organs.\n“A cardiac arrest, the word \"arrest\" means to stop. And so cardiac arrest means the heart has stopped. There are many reasons why the heart will stop. In the United States, 1,000 people every day suffer from sudden cardiac arrest. One cause of the heart stopping is a heart attack. But not every heart attack leads to the heart stopping.\nIn the United States, about 1,000,000 people per year will have a heart attack. That is where the blood supply to a coronary artery is disrupted and stopped, and heart muscle begins to die. That is a heart attack. Generally, those patients are treated by cardiologists and treated with clot busting medications or taken to cardiac catheterization labs for small implantable devices called coronary stents are placed to open up the artery, alleviate the obstruction the clot to allow normalization of blood flow.\nBut again, having a heart attack or stoppage of blood supply to the heart muscle, while it may cause the heart to stop, is completely different from the heart stopping. Heart stopping can happen for other reasons outside of heart attacks. Drugs or other type of environmental or other exposures can cause the heart to stop.”\n~ Dr. Bryan White, member of the Adult Resuscitation Sub-Council of the Scientific Advisory Council\nLearn more about the\ndifference between heart attack and cardiac arrest\n.\nHeart Attack Symptoms in Women\nAlthough men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or vomiting; extreme fatigue; and dizziness or light-headedness.\n“Signs of a heart attack in women can be different than they are in men. While men can have chest pain that radiates down the left arm, for women it can be other symptoms like shortness of breath, dizziness, Lightheadedness. Sometimes individuals may not have any chest pain at all. And so, it's important to be aware that there are differences for heart attacks between men and women.”\n~ Dr. Jestin Carlson, Red Cross Scientific Advisory Council, First Aid Sub-Council\nHelp Save Lives with an American Red Cross Class\nMore than 4.6M people turn to us, the trusted training provider for First Aid, CPR, BLS and more, every year to gain lifesaving skills.

Because the cells in the affected area of the heart muscle are not receiving the oxygen and nutrients they need, they become damaged and can die, causing the heart to not pump normally and if untreated, stop pumping blood. Calling 9-1-1 as soon as you recognize the signs and symptoms of a heart attack can minimize the damage to the heart and may save the person’s life.\n  \n  Find a Class\n  \n  ## Are the signs and symptoms of a heart attack the same for everyone?\n  Signs and symptoms of a heart attack vary from person to person and can be different in women than they are in men. Even people who have had a heart attack before may not experience the same signs and symptoms if they have a second heart attack. The signs and symptoms of a heart attack may also be more subtle in people with certain medical conditions, such as diabetes. If you suspect a heart attack, always respond as if it is one. Although men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or [vomiting](https:\/\/www.redcross.org\/take-a-class\/resources\/learn-first-aid\/vomiting); extreme fatigue; and dizziness or light-headedness.\n  \n  ## Emergency Steps\n  1\n  \n  Check the scene safety, form an initial impression, obtain consent and put on PPE, as appropriate.\n  ***\n  2\n  \n  Check for signs and symptoms.\n  \n  - Persistent chest pain longer than 3 to 5 minutes or goes away and comes back\\*\n  - Chest pressure, squeezing, tightness, aching or heaviness\\*\n  - Isolated unexplained discomfort or pain spreading to arms, neck, jaw, back or stomach\\*\n  - Trouble breathing\\*\n  - Pale, gray or bluish skin\\*\n  - Feeling of anxiety or impending doom\\*\n  - Unresponsiveness\\*\n  - Dizziness\\*\n  - Nausea, vomiting, extreme fatigue or sweating\n  \n  \\*Note: Signs and symptoms with a \\* require immediate emergency medical treatment.\n  ***\n  3\n  \n  Call 9-1-1 and get equipment, including an AED if available, if the person requires immediate emergency medical treatment.\n  ***\n  4\n  \n  Give Care.\n  ***\n  ## General Care: Heart Attack\n  1. Have them stop activity and rest in a comfortable position.\n  2. If they are awake, can understand simple commands, and can chew or swallow and are allowed to have aspirin, assist them to take two to four low-dose (81-mg) aspirin tablets (162 to 324 mg) or one regular-strength (325-mg) aspirin tablet.\n  3. If they have prescribed medication such as nitroglycerin, offer to assist with taking it.\n  4. Loosen tight or uncomfortable clothing.\n  5. Continue checking them as appropriate to determine if additional care is needed.\n  6. Keep person from getting cold or overheated.\n  7. Give care for shock, if necessary.\n  8. Stay with them until EMS arrives.\n  9. Reassure person you will help and that EMS has been called (if appropriate).\n  10. Watch for changes in condition, including breathing and responsiveness until EMS arrives, and give care as appropriate and trained.\n  11. Be prepared to give CPR or compression-only CPR based on level of training and use an AED when available if they become unresponsive and are not breathing (cardiac arrest).\n  \n  ## Heart Attack FAQs\n  #### What are some tips to help save the life of a person with a heart attack?\n  - Call 9-1-1 immediately if you think someone is having a heart attack.\n  - Get or instruct someone to get an AED if there is one available.\n  - Never drive a person to the hospital yourself.\n  - Don’t delay seeking care by disregarding signs and symptoms.\n  - Don’t worry about causing a “false alarm” by calling 9-1-1.\n  - Remember: Most people that succumb to fatal heart attacks die within the first 2 hours of signs and symptoms. Early care saves lives.\n  \n  #### I’ve heard that women may have different symptoms of a heart attack than men. Is this true?\n  Although men often have “classic” signs and symptoms of a heart attack, such as chest pain radiating down one arm, women may have more subtle signs and symptoms or experience a heart attack differently than men do.\n  \n  For example, the “classic” signs and symptoms in women may be milder or accompanied by more general signs and symptoms such as back pain, shortness of breath, nausea or vomiting, extreme fatigue, and dizziness or light-headedness. Because these signs and symptoms are general and nonspecific, women may experience them for hours, days or even weeks leading up to the heart attack but dismiss them as nothing out of the ordinary.\n  \n  ![Symptoms of heart attack in women: chest pain, fatigue, nausea and shortness of breath.](data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%200%200'%3E%3C\/svg%3E)\n  ## Difference Between Heart Attack and Cardiac Arrest\n  A heart attack and cardiac arrest are not the same thing. A heart attack is a blockage of the blood vessels that supply oxygen to the heart muscle. The person may be awake, and if left untreated the heart attack may progress to cardiac arrest. Cardiac arrest is when the heart stops beating or beats too ineffectively to circulate blood to the brain and other vital organs.\n  \n  “A cardiac arrest, the word \"arrest\" means to stop. And so cardiac arrest means the heart has stopped. There are many reasons why the heart will stop. In the United States, 1,000 people every day suffer from sudden cardiac arrest. One cause of the heart stopping is a heart attack. But not every heart attack leads to the heart stopping.\n  \n  In the United States, about 1,000,000 people per year will have a heart attack. That is where the blood supply to a coronary artery is disrupted and stopped, and heart muscle begins to die. That is a heart attack. Generally, those patients are treated by cardiologists and treated with clot busting medications or taken to cardiac catheterization labs for small implantable devices called coronary stents are placed to open up the artery, alleviate the obstruction the clot to allow normalization of blood flow.\n  \n  But again, having a heart attack or stoppage of blood supply to the heart muscle, while it may cause the heart to stop, is completely different from the heart stopping. Heart stopping can happen for other reasons outside of heart attacks. Drugs or other type of environmental or other exposures can cause the heart to stop.”\n  \n  ~ Dr. Bryan White, member of the Adult Resuscitation Sub-Council of the Scientific Advisory Council\n  \n  Learn more about the [difference between heart attack and cardiac arrest](https:\/\/www.redcross.org\/take-a-class\/resources\/articles\/heart-attack-vs-cardiac-arrest).\n  \n  ## Heart Attack Symptoms in Women\n  Although men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or vomiting; extreme fatigue; and dizziness or light-headedness.\n  \n  “Signs of a heart attack in women can be different than they are in men. While men can have chest pain that radiates down the left arm, for women it can be other symptoms like shortness of breath, dizziness, Lightheadedness. Sometimes individuals may not have any chest pain at all. And so, it's important to be aware that there are differences for heart attacks between men and women.”   \n  ~ Dr. Jestin Carlson, Red Cross Scientific Advisory Council, First Aid Sub-Council\n  \n  ## Help Save Lives with an American Red Cross Class\n  More than 4.6M people turn to us, the trusted training provider for First Aid, CPR, BLS and more, every year to gain lifesaving skills.

# Heart Attack ## What is a Heart Attack? A heart attack happens when blood supply to part of the heart muscle is blocked. Because the cells in the affected area of the heart muscle are not receiving the oxygen and nutrients they need, they become damaged and can die, causing the heart to not pump normally and if untreated, stop pumping blood. Calling 9-1-1 as soon as you recognize the signs and symptoms of a heart attack can minimize the damage to the heart and may save the person’s life. Find a Class ## Are the signs and symptoms of a heart attack the same for everyone? Signs and symptoms of a heart attack vary from person to person and can be different in women than they are in men. Even people who have had a heart attack before may not experience the same signs and symptoms if they have a second heart attack. The signs and symptoms of a heart attack may also be more subtle in people with certain medical conditions, such as diabetes. If you suspect a heart attack, always respond as if it is one. Although men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or [vomiting](https://www.redcross.org/take-a-class/resources/learn-first-aid/vomiting); extreme fatigue; and dizziness or light-headedness. ## Emergency Steps 1 Check the scene safety, form an initial impression, obtain consent and put on PPE, as appropriate. *** 2 Check for signs and symptoms. - Persistent chest pain longer than 3 to 5 minutes or goes away and comes back\* - Chest pressure, squeezing, tightness, aching or heaviness\* - Isolated unexplained discomfort or pain spreading to arms, neck, jaw, back or stomach\* - Trouble breathing\* - Pale, gray or bluish skin\* - Feeling of anxiety or impending doom\* - Unresponsiveness\* - Dizziness\* - Nausea, vomiting, extreme fatigue or sweating \Note: Signs and symptoms with a \ require immediate emergency medical treatment. * 3 Call 9-1-1 and get equipment, including an AED if available, if the person requires immediate emergency medical treatment. * 4 Give Care. * ## General Care: Heart Attack 1. Have them stop activity and rest in a comfortable position. 2. If they are awake, can understand simple commands, and can chew or swallow and are allowed to have aspirin, assist them to take two to four low-dose (81-mg) aspirin tablets (162 to 324 mg) or one regular-strength (325-mg) aspirin tablet. 3. If they have prescribed medication such as nitroglycerin, offer to assist with taking it. 4. Loosen tight or uncomfortable clothing. 5. Continue checking them as appropriate to determine if additional care is needed. 6. Keep person from getting cold or overheated. 7. Give care for shock, if necessary. 8. Stay with them until EMS arrives. 9. Reassure person you will help and that EMS has been called (if appropriate). 10. Watch for changes in condition, including breathing and responsiveness until EMS arrives, and give care as appropriate and trained. 11. Be prepared to give CPR or compression-only CPR based on level of training and use an AED when available if they become unresponsive and are not breathing (cardiac arrest). ## Heart Attack FAQs #### What are some tips to help save the life of a person with a heart attack? - Call 9-1-1 immediately if you think someone is having a heart attack. - Get or instruct someone to get an AED if there is one available. - Never drive a person to the hospital yourself. - Don’t delay seeking care by disregarding signs and symptoms. - Don’t worry about causing a “false alarm” by calling 9-1-1. - Remember: Most people that succumb to fatal heart attacks die within the first 2 hours of signs and symptoms. Early care saves lives. #### I’ve heard that women may have different symptoms of a heart attack than men. Is this true? Although men often have “classic” signs and symptoms of a heart attack, such as chest pain radiating down one arm, women may have more subtle signs and symptoms or experience a heart attack differently than men do. For example, the “classic” signs and symptoms in women may be milder or accompanied by more general signs and symptoms such as back pain, shortness of breath, nausea or vomiting, extreme fatigue, and dizziness or light-headedness. Because these signs and symptoms are general and nonspecific, women may experience them for hours, days or even weeks leading up to the heart attack but dismiss them as nothing out of the ordinary. ![Symptoms of heart attack in women: chest pain, fatigue, nausea and shortness of breath.](data:image/svg+xml,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%20viewBox='0%200%200%200'%3E%3C/svg%3E) ## Difference Between Heart Attack and Cardiac Arrest A heart attack and cardiac arrest are not the same thing. A heart attack is a blockage of the blood vessels that supply oxygen to the heart muscle. The person may be awake, and if left untreated the heart attack may progress to cardiac arrest. Cardiac arrest is when the heart stops beating or beats too ineffectively to circulate blood to the brain and other vital organs. “A cardiac arrest, the word "arrest" means to stop. And so cardiac arrest means the heart has stopped. There are many reasons why the heart will stop. In the United States, 1,000 people every day suffer from sudden cardiac arrest. One cause of the heart stopping is a heart attack. But not every heart attack leads to the heart stopping. In the United States, about 1,000,000 people per year will have a heart attack. That is where the blood supply to a coronary artery is disrupted and stopped, and heart muscle begins to die. That is a heart attack. Generally, those patients are treated by cardiologists and treated with clot busting medications or taken to cardiac catheterization labs for small implantable devices called coronary stents are placed to open up the artery, alleviate the obstruction the clot to allow normalization of blood flow. But again, having a heart attack or stoppage of blood supply to the heart muscle, while it may cause the heart to stop, is completely different from the heart stopping. Heart stopping can happen for other reasons outside of heart attacks. Drugs or other type of environmental or other exposures can cause the heart to stop.” ~ Dr. Bryan White, member of the Adult Resuscitation Sub-Council of the Scientific Advisory Council Learn more about the [difference between heart attack and cardiac arrest](https://www.redcross.org/take-a-class/resources/articles/heart-attack-vs-cardiac-arrest). ## Heart Attack Symptoms in Women Although men often have the “classic” signs and symptoms of a heart attack, such as chest pain that radiates down one arm, women often have more subtle signs and symptoms or experience the signs and symptoms of a heart attack differently than men do. For example, in women, the “classic” signs and symptoms may be milder or accompanied by more general signs and symptoms such as shortness of breath; nausea or vomiting; extreme fatigue; and dizziness or light-headedness. “Signs of a heart attack in women can be different than they are in men. While men can have chest pain that radiates down the left arm, for women it can be other symptoms like shortness of breath, dizziness, Lightheadedness. Sometimes individuals may not have any chest pain at all. And so, it's important to be aware that there are differences for heart attacks between men and women.” ~ Dr. Jestin Carlson, Red Cross Scientific Advisory Council, First Aid Sub-Council ## Help Save Lives with an American Red Cross Class More than 4.6M people turn to us, the trusted training provider for First Aid, CPR, BLS and more, every year to gain lifesaving skills.
