What is a Heart Attack?
A heart attack (medically called a myocardial infarction) occurs when the blood flow that brings oxygen to the heart muscle is severely cut off or completely blocked. This is typically caused by a buildup of fat, cholesterol, and other substances, which form a plaque in the arteries supplying the heart (coronary arteries).
Immediate "Rescue" or First Aid Steps
If someone is having a heart attack, the true "rescue" requires professional emergency medical treatment to clear the blockage. However, while waiting for the ambulance, these immediate actions can help save a life:
- Call Emergency Services First: This is the most critical step. Every minute matters.
- Chew an Aspirin (if safe): If the person is fully conscious and not allergic to aspirin, having them chew a standard adult aspirin (325 mg) or 2-4 low-dose baby aspirins (81 mg each) can help. Chewing it helps it enter the bloodstream faster to thin the blood and keep a blood clot from growing.
- Rest and Stay Calm: Have the person sit down, rest, and try to stay calm. Physical exertion puts more strain on an already struggling heart.
- Perform CPR if Unconscious: If the person stops breathing or loses consciousness, immediately begin Cardiopulmonary Resuscitation (CPR). Push hard and fast in the center of the chest at a rate of 100 to 120 compressions per minute until medical help arrives.
What Medical Professionals Use to Rescue the Heart
Once emergency responders or doctors take over, they use specific medical interventions to restore blood flow:
- Thrombolytics ("Clot Busters"): Intravenous drugs given in the hospital to dissolve the blood clot that is blocking the artery.
- Coronary Angioplasty and Stenting: A procedure where doctors thread a thin tube (catheter) through a blood vessel to the blocked artery. A tiny balloon is inflated to open the artery, and a small mesh tube (stent) is left in place to keep it open.
- Nitroglycerin: A medication that widens the blood vessels, making it easier for blood to flow and reducing chest pain.
