Recognize a Heart Attack
If you are experiencing any signs of a heart attack dial 911 immediately
A heart attack is a medical emergency. Recognizing the signs is the first critical step in cardiac care.
Your heart is a muscle. Its job is to pump blood around your body. The heart is about the size of your fist and is protected by your ribs and breastbone (sternum). It beats about 100,000 times a day.
Each beat of your heart pumps blood through a network of arteries and veins. Blood delivers essential oxygen and nutrients to every cell. Blood takes away waste products and carbon dioxide. Arteries carry oxygen-rich blood from the heart throughout the body. Veins carry oxygen-poor blood back to your heart and lungs to start the cycle over again. Like any other muscle, the heart needs its own supply of oxygen-rich blood to function. The coronary arteries handle this job.
In a person with coronary artery disease, the coronary arteries become narrowed or blocked so your heart does not get enough oxygen to do its job effectively.
With your heart being so vital, we need to recognize the signs that something is not right and seek medical attention immediately.
The sign of a heart attack can vary and may be different for men and women.
- Chest Discomfort – Pressure, squeezing, fullness or pain, burning or heaviness
- Upper Body Discomfort – neck, jaw, shoulder, arms, back
- Shortness of Breath
The most common sign of a heart attack is chest pain or discomfort; however, women can experience a heart attack without chest pain. Women may experience shortness of breath, pressure or pain in the lower chest or upper abdomen (“severe heart burn”), dizziness, lightheadedness or fainting, upper back pressure or extreme fatigue.
Thousands of Canadians die from heart attacks each year. It is important to recognize the signs and act quickly. You could save a life.
