HEART ATTACK. Signs & Symptoms. Statistics
Signs & Symptoms
Coronary heart disease is the No. 1 cause of death in the United States. Stroke is the No. 3 cause of death in the United States and a leading cause of serious disability. That's why it's so important to reduce your risk factors, know the warning signs, and know how to respond quickly and properly if warning signs occur.
How It Works
Death of or damage to part of the heart muscle due to an insufficient blood supply. Heart attacks occur when one of the coronary arteries that supply blood to the heart muscle is blocked. Blockage is usually caused from a buildup of plaque (deposits of fat-like substances) due to atherosclerosis. If a plaque deposit tears or ruptures, a blood clot may form and block the artery, causing a heart attack.
Heart Attack Warning Signs
Minutes matter! Fast action can save lives — maybe your own.
What Are the Effects of Stroke?
The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should.
Stroke is a medical emergency. Know these warning signs of stroke and teach them to others. Every second counts:
Call 9-1-1 immediately if you experience symptoms!Time lost is brain lost!
Cardiac arrest strikes immediately and without warning.
ABCs of Preventing
Heart Attack,Stroke and Heart Disease
If you've ever watched a hospital show on TV, you've probably seen cardiopulmonary resuscitation
(say: kar-dee-o-pul-muh-ner-ee rih-suh-sih-tay-shun).
That's when a doctor or another rescuer breathes into someone's mouth and presses on the person's chest. It's called CPR for short and it saves lives.
Let's find out how it works.
What Is CPR?
Cardio means "of the heart" and pulmonary means "of the lungs." Resuscitation is a medical word that means "to revive" — or bring back to life. Sometimes CPR can help a person who has stopped breathing, and whose heart may have stopped beating, to stay alive.
Here's what takes place during CPR: A person giving CPR — called a rescuer — will give some breaths to someone who is not breathing on his or her own. This is called artificial respiration (say: ar-tuh-fih-shul res-puh-ray-shun), mouth-to-mouth rescue breathing, or mouth-to-mouth resuscitation.
How does CPR Work
If an emergency happens do your best to stay calm. First, try to get the person to respond by gently shaking his or her shoulder and asking, "Are you OK?" If there is no response and you are certified in CPR, you can begin CPR. (If you're alone, shout for help or call 911 yourself)
A rescuer puts his or her mouth over the other person's open mouth and blows, forcing air into the lungs. Rescue breathing helps to move oxygen, down into the lungs of the person who isn't breathing. After giving two breaths, the rescuer will use both hands, one placed over the other, to press on the person's chest to move blood out of a heart that has stopped beating. These are called chest compressions and they help move oxygen-carrying blood to the body's vital organs — especially the all-important brain. The cycle continues until help arrives.
The rescuer can keep the person alive by continuing to supply blood and oxygen to the brain and the rest of the body, until emergency help — like the paramedics — arrives to take the person to a hospital.
When Should Someone Use CPR?
Who Should Know CPR?
Many people — maybe you — may want to learn how to do CPR just in case they need to use it someday. You can never tell when a medical emergency will happen and it feels good to know that you could help.
