A matter known as plaque makes up on the inner walls of the arteries. This can occur in any artery, also in the coronary arteries. The coronary arteries take rich blood containing oxygen to the heart. When atherosclerosis has an effect on the coronary arteries, then this condition is known as coronary artery disease or CAD.

Tightly folded balloons are passed inside the narrowed artery vessels to pump up them to a normal size and they contain about 75 to 500 times pressure to that of blood.

Coronary angioplasty is a therapeutic procedure in which a balloon is inserted inside the heart to open an obstacle in a coronary (heart) artery which is narrowed because of atherosclerosis. This procedure is beneficial for the heart as it increases the blood flow in it and in whole body.

Some of the benefits of angioplasty are here:

• Recover and improve the symptoms of coronary artery diseases like angina and lacking in breathing.
• Decrease harm to the muscle of heart from a heart attack. A heart attack takes place when the flow of blood through a coronary artery is blocked completely. Angioplasty is used during a heart attack to open the blockage and restore blood flow through the artery.
• Decrease the risk of death in some patients. Hence saving humanity from a worse disease.

There are more than 5 million peoples go through angioplasty in world from a research. However serious complications do not happen to most of the people but still there are chances for these complications and doctors are getting more specialized and specific knowledge to overcome this circumstance.

Research on the knowledge of angioplasty is going further to formulate it safer, helpful and more successful, to avoid healed arteries from closing again, and to make the practice a choice for more people.
