SN instructed patient on spontaneous coronary artery dissection ( SCAD ) and stent placement. A stent is a small rod made out of metal or fabric. It is inserted into a coronary artery when there is a blockage or when the artery is narrow. A coronary artery is a blood vessel that carries oxygen to the heart muscle. You received a stent due to coronary artery disease ( also called SCAD). That is caused by a thickening of the inside walls of the coronary arteries. This thickening is called atherosclerosis. A fatty substance called plaque builds up inside the thickened walls of the arteries, blocking or slowing the flow of blood. If your heart muscle doesn't get enough blood to work properly, you may have angina ( chest pain ) or a heart attack. The stent will help hold the artery open so blood can flow and help keep the artery from narrowing again. You will need to take medicine that keeps the stent open and blood flowing. It is very important to take the medicine exactly how your doctor tells you to take it. In addition to taking medicine, the best way to keep your heart healthy is to maintain a healthy lifestyle. Quit smoking. Make sure you keep your blood pressure and cholesterol at healthy levels. Exercise as recommended by your doctor. Eat a heart - healthy diet. Patient verbalized understanding well.
