What is heart attack ?

Like all other muscles in your body, the heart muscle requires blood to survive. Coronary arteries carry blood to the heart and a heart attack occurs when an area of your heart muscle does not receive its blood supply. The blood supply to the heart is usually blocked when a build-up of fatty tissue, or plaque, on the artery wall cracks. Blood cells and other parts of the blood stick over the damaged area and form a clot that suddenly and completely blocks the blood ow to your heart muscle. As a result, the part of your heart muscle that is not getting enough blood starts to die.

What are the warning signs of heart attack?

The warning signs of heart attack vary from person to person. Heart attacks are not always sudden or severe. Many start slowly with only mild pain or discomfort. Symptoms can come on suddenly or develop over minutes and get progressively worse. Symptoms usually last for at least 10 minutes. You may have just one symptom or a combination of symptoms

Symptoms include tightness, pressure, heaviness or pain in your chest, neck, jaw, shoulder/s, back or arm/s. This pain or discomfort may start in your chest and spread to these other areas of your upper body. You may not get chest pain at all, but just feel pain or discomfort in one or more of these other areas.

You may have a choking feeling in your throat. Your arms may feel heavy or useless. You may also feel short of breath, nauseous, have a cold sweat and/or feel dizzy or light-headed. People who have a heart attack usually have some warning signs. Unfortunately, many people who experience warning signs wait too long before getting help. With a heart attack, every minute counts. Too many people lose their lives because they take too long to call Triple Zero (000) for an ambulance. Getting to hospital quickly can reduce the damage to your heart muscle and increase your chance of survival. In hospital, staff will give you treatments that help reduce this damage.
