Angioplasty

The heart muscle depends on a regular and optimum supply of oxygen to function properly. In turn, it pumps blood throughout the body. The oxygen supply to the heart is completed with the help of a system of coronary arteries.The blood flowing through the coronary arteries carries oxygen to the heart muscles. Sometimes deposits of substances like cholesterol,excess muscle cells, collagen and sometimes the accumulation of proteins on the inner walls of the arteries cause narrowing and hardening of these blood vessels.This process in medical term is known as "atherosclerosis".
Blockage of an artery in this way starves the heart of oxygen. If the blockage is mild only pain results. If severe, the part of the heart that is starved of oxygen actually dies—this is what we call a heart attack .An angioplasty is a medical procedure used to open a blocked coronary artery and improves blood flow to the heart.
Sometimes after a heart attack, surgeons attempt to open up a clogged artery through a technique called 'Balloon Angioplasty.'In balloon angioplasty, a long tube (catheter) with a balloon at one end is inserted through the groin and is guided to the clogged artery in the heart. At the site the balloon is inflated. The inflated balloon crushes the plaque (deposit) on the artery wall. The balloon is then deflated and withdrawn.
Besides balloon angioplasty there is another technique called laser angioplasty in which a laser beam is used to cut through the plaque.
After the procedure, your doctor may insert a device called a stent to keep the artery open for a longer period of time. In most cases, this procedure is safe and effective. If complications occur, they can include nausea, minor infections, and temporary pain.

What is Angioplasty ?

Balloon angioplasty (also known as just angioplasty) is a procedure that allows your doctor to open blocked coronary arteries, which are the arteries that provide oxygen and nutrients to your heart muscle. In this procedure a balloon catheter (thin tube) is inserted into a blocked artery to remove the blockage. The blockage may be present in an artery in the arm, leg, or in the heart.
The catheter is inserted into a blood vessel either at the elbow or groin. It is pushed through the inside of the blood vessel so that the tip of the catheter is at the point of the blockage in the artery. The narrowed artery is stretched by inflating a balloon at the tip of the catheter allowing blood to flow normally through the artery again. The doctor then removes the catheter and balloon.
Often, an expandable device, called a stent, is inserted into your blocked artery after the procedure. Stents can help the artery remain open for a longer period of time. Your doctor's choice to perform an angioplasty or insert a stent is based on the type and location of your blockage.In addition to being effective, this procedure is safe and well tolerated in most cases.

What are the causes of blocked coronary artery?

Research have revealed that blockage in the coronary artery starts when certain factors damage the inner layers of the coronary arteries. These factors are...

Smoking
High percentage of certain fats and cholesterol in the blood
High blood pressure
High percentage of sugar in the blood due to insulin resistance or diabetes
When damage occurs, your body starts a healing process. Excess fatty tissues release compounds that enhence this process. This healing causes plaque on the inner walls of the arteries cause narrowing and hardening of these blood vessels. The buildup of plaque in the coronary arteries may start from childhood. Over time with age, plaque can narrow or completely block some of your coronary arteries. This results in reduced flow of oxygen-rich blood to your heart muscle. Plaque also can crack, which causes blood cells called platelets (PLATE-lets) to clump together and form blood clots at the site of the cracks. This narrows the arteries more and worsens angina or causes a heart attack.
