A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart is blocked for a prolonged period, leading to damage or death of the heart muscle tissue.
This blockage is typically caused by a buildup of fatty deposits (plaques) in the coronary arteries, which supply oxygen-rich blood to the heart muscle. When the blood flow is blocked, the affected part of the heart muscle is deprived of oxygen and nutrients, leading to tissue damage or death.
Heart attacks can range from mild to severe and can be life-threatening if not treated; therefore, recognizing the signs of a heart attack is crucial for prompt treatment. Look out for these common symptoms:
Chest pain or discomfort: This is the most common symptom. It may feel like pressure, tightness, squeezing, or pain in the center or left side of the chest. It can last for more than a few minutes or go away and come back.
Shortness of breath: Feeling breathless, even when resting or with minimal exertion, can be a sign of a heart attack.
Discomfort in other areas of the upper body: Pain, discomfort, or numbness may be felt in one or both arms, the back, neck, jaw, or stomach.
Nausea, indigestion, or abdominal pain: Some people may experience these symptoms during a heart attack, especially women.
Lightheadedness or dizziness: Feeling faint or dizzy can occur during a heart attack.
Cold sweat: A sudden, cold sweat with no apparent reason can be a symptom of a heart attack.
Fatigue: Unusual tiredness or weakness, especially if it's sudden or extreme, can be a sign of a heart attack.
If you suspect someone is having a heart attack, follow these steps:
Call emergency services: Immediately dial your local emergency number to get professional medical help on the way.
Help the person rest: Have them sit or lie down in a comfortable position. Loosen any tight clothing to help them breathe more easily.
Aspirin: If the person is not allergic to aspirin and they are conscious, you can give them a regular, low-dose aspirin to chew. Aspirin can help prevent blood clotting and reduce the severity of the heart attack.
Monitor the person: Stay with the person and monitor their condition while waiting for emergency services to arrive. Be prepared to perform CPR if necessary.
Do not give food or drink: Refrain from giving the person anything to eat or drink. It's important to avoid anything that could potentially worsen the situation, such as choking.
Remember, time is of the essence during a heart attack. The quicker professional medical help arrives, the better the chances of a positive outcome.
Important Tips:
Do not give anything by mouth other than aspirin, as it could interfere with emergency treatments.
Do not leave the person alone unless you need to call for help and no one else is available to do so.
Avoid unnecessary movements to reduce strain on the heart.
Prompt and efficient first aid can significantly improve the chances of survival and recovery for someone experiencing a heart attack.
