cardiac tissue and seem to be more reliable to indicate possible Myocardial Infarction. ANGIOPLASTY: A process in which a balloon is threaded through the aorta, into a blocked coronary artery. The balloon is inflated which flattens the deposits against the vessel wall. Sometimes a STENT , a wire mesh tube, is also inserted to hold the vessel open, allowing for increased blood flow. CORONARY BYPASS Surgical procedure done when coronary arteries are blocked. Healthy segments of blood vessels are taken from other parts of patient’s body and are used to re-route the blood, around the obstruction. A HEART-LUNG MACHINE is used during the procedure. The heart can be stopped so the surgeons can work, but the patient’s blood goes through the machine, where it is oxygenated and CO2 removed. ENZYMES When clots are causing an Myocardial Infarction, STREPTOKINASE. T-PA or UROKINASE can be used to break up the clot. They activate the inactive plasminogen into PLASMIN, which breaks down the clot. They need to be given ASAP. HEART TRANSPLANT Surgical procedure in which a diseased heart is removed and replaced by one from a immunocompatible donor. Patient’s must take drugs that suppress their immune systems for the rest of their lives in order to avoid rejection. ARTIFICIAL HEART: Mechanical pump that replaces the heart. Only being used as a “stop-gap”, until a donor heart can be found. CARDIAC ASSISTED DEVICE Implanted mechanism that assists heart in its functioning. Originally designed to be temporary until donor heart is found. Readings - Read and study on your own.
