The heart is probably the hardest working muscle in the body. Pumping life through your veins day in and day out; though sometimes even the heart needs a little help to function at it's best. Take, for example, a condition like coronary artery disease. This heart condition indicates the presence of any of the heart condition which causes an insufficiency in the blood flow to the heart. Heart attack and angina are some of the known result of restrictions to blood flow. This restriction in blood flow is caused by the layer of fatty deposits on the artery walls, also called as atheroma. This may lead to discomfort and pain in the chest, called angina. If the plaque (fatty deposits) of the atheroma crack, a blood clot is formed to repair the artery wall, thus blocking the artery further. This causes a heart attack. During a heart attack, due to restricted blood flow, the affected heart muscles are damaged and stop functioning partially or fully. Different Kinds of Heart Surgery There are multiple ways to treat these conditions, coronary angioplasty and coronary artery bypass surgery being the two important surgeries to treat it. Coronary angioplasty is a procedure that squashes the fatty deposits on the walls of the coronary artery to make way for the blood to flow. Angioplasty is a fairly familiar procedure; however, it has been, now, optimised to getting the patient back on their feet following the procedure. Effectively, reducing the recovery time and helping you get back to daily life faster than if you'd undergone the procedure couple of years back. A Coronary angioplasty may involve placement of devices called 'stents,' depending on the type and extent of blockages in the coronary arteries. Stents are wire mesh tubes which are accurately placed in the part of the artery that was blocked, to reopen it and re-establish the blood flow.
