Smoking is one of the six main reasons why heart attacks are caused. It has been investigated that individuals under the age of 40 who smoke tobacco products have a five times higher chance of having a heart attack than non-smokers.

What smoking does to cause heart attacks:
  • Every cigarette does harm to your body and gets you closer to having a heart attack. The toxic substances found in the tobacco such as carbon monoxide and nicotine, can cause the arteries to harden and become narrower which stops bloodflow to vital organs.
  • When you smoke a cigarette, it is harder to receive oxygen because of carbon monoxide in the tobacco.
  • Eventually the lungs and repiratory system become swollen and damaged.
  • After many years, arteries tend to narrow and blood clots will form along the arterial wall.
  • If a blood clot is formed in the body, it can block flow of blood.
All of the above can cause a heart attack, risking your life.

The symptoms of a heart attack include chest pain and pain that travels down the shoulder and arm. Or you may experience the unusal symptoms such as shortness of breath, fatigue or weakness.
