Coronary Artery Disease (CAD) results in narrowing or blockage of coronary arteries and while decreasing blood supply to the heart. The aim of treatment in CAD is to increase the blood supply to the heart and to decrease its demand.
This concept of supply and demand needs some explanation. The heart is greedy for blood because it has to do so much work. We may give it more blood by medicines or opening blocked vessels by means of angioplasty or by connecting other vessels in the Bypass operation. On the other hand, we can decrease its demand with medicines like beta-blockers. This will keep the heart healthy and enable it to work, with lesser amount of blood.
PTCA is short for Percutaneous Transluminal Coronary Angioplasty. In coronary artery blockages, stretching or dilating the vessel can open the blockage. This procedure is a non-operative alternative to Bypass Surgery and can be done by a small puncture on the thigh or the arm. Patients are awake when they undergo this procedure. Only one or two days of hospital stay is required.
