Heart attack


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.

The normal heart

The Normal Heart

  • The normal heart is a pump made of muscle tissue. It's about the size of your fist.

  • The heart has four chambers. The two upper ones are the atria, and the lower two are the ventricles. (See diagram.) Four heart valves open and close to keep the blood flowing in one direction as it's pumped through the heart. Each valve has a set of "flaps" (also called leaflets or cusps).

Heart attack

How It Works

  • Dark bluish (oxygen-poor) blood returns to the heart after circulating through the body.

  • Enters the right atrium.

  • Then goes into the right ventricle.

  • The right ventricle pumps blood under low pressure into the pulmonary artery.

  • From there the blood goes to the lungs, where it gets fresh oxygen. Oxygen-rich blood is bright red.

  • Now goes to the left atrium.

  • Then enters the left ventricle

  • Then into the aorta which takes the blood from the heart to the rest of the body.

  • The cycle repeats as the blood flows back to the right atrium.

What is a heart attack also known as myocardial infarction

What is a Heart Attack?Also known as Myocardial Infarction

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

  • Some heart attacks are sudden and intense. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what's wrong and wait too long before getting help. Here are signs that can mean a heart attack is happening:

    • Chest discomfort. Most heart attacks involve discomfort in the center of the chest, it can feel like uncomfortable pressure, squeezing, fullness or pain.   

    • Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.   

    • Shortness of breath with or without chest discomfort.  

    • Other signs may include breaking out in a cold sweat, nausea or lightheadedness       

Minutes matter! Fast action can save lives — maybe your own.

What is a stroke

What is a Stroke?

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.

Learn to recognize a stroke

Learn To Recognize A Stroke

Stroke is a medical emergency. Know these warning signs of stroke and teach them to others. Every second counts:

  • Sudden numbness or weakness of the face, arm or leg, especially on one side of the body

  • Sudden confusion, trouble speaking or understanding

  • Sudden trouble seeing in one or both eyes

  • Sudden trouble walking, dizziness, loss of balance or coordination

  • Sudden, severe headache with no known cause

Call 9-1-1 immediately if you experience symptoms!Time lost is brain lost!

Heart attack

Cardiac arrest strikes immediately and without warning.

  • Cardiac arrest is the sudden, abrupt loss of heart function. Here are the signs:

  • Sudden loss of responsiveness (no response to tapping on shoulders).

  • No normal breathing

  • If these signs of cardiac arrest are present, tell someone to call 9-1-1 and get an AED (Automated External Defibrillator) if one is available and you begin CPR immediately.

Why should you learn CPR?

Heart attack

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.

Heart attack

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.

Heart attack

When Should Someone Use CPR?

  • Someone can stop breathing and/or have cardiac arrest from:

  • heart attacks

  • strokes (when the blood flow to a part of the brain suddenly stops)

  • choking on something that blocks the entire airway

  • near-drowning incidents (when someone is under water for too long and stops breathing)

  • a very bad neck, head, or back injury

  • severe electrical shocks (like from touching a power line)

  • being very sick from a serious infection

  • too much bleeding

  • severe allergic reactions

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.
