Angioplasty is a non-surgical procedure, which opens blocked coronary arteries and restores blood flow to the heart.
The heart is a muscular organ at the centre of the circulatory system that contracts and relaxes rhythmically to pump blood into different blood vessels, which carries it to the different parts of the body.
The coronary arteries supply oxygen-rich blood to the heart.If any of the coronary arteries become narrow or blocked, due to cholesterol buildup and fatty deposits (plaque), the blood flow to that part of the heart becomes slow or gets blocked as a result. The plaque accumulates over time and the arteries harden. The hardened arteries are unable to expand to their fullest capacity, thereby reducing the flow of oxygen and blood supply to parts of the heart.
When a particular part of the heart does not receive enough oxygen or blood, tissue damage or death may occur in that part, unless the blockage is quickly removed. This can result in a condition called Coronary Atherosclerosis or in simpler terms, clogged arteries, which can lead to chest pain (also known as angina), or even a stroke, or a heart attack.
