Plaque narrows the coronary arteries, reducing the flow of oxygen-rich blood to the heart muscle. Risk Factor & Symptoms : Risk Factor & Symptoms High blood cholesterol, High blood pressure, Diabetes, Smoking may lead to CHD. (When your coronary arteries are narrowed or blocked, oxygen-rich blood can't reach your heart muscle). This can cause angina (chest pain) heart attack. Block Right Coronary Artery : Block Right Coronary Artery Stent Procedure : Stent Procedure For Arteries Narrowed by Plaque This procedure usually takes about an hour The area where the catheter is inserted will be numbed, and you won't feel the doctor threading the catheter, balloon, or stent inside the artery. You may feel some pain when the balloon is expanded to push the stent into place. For Aortic Aneurysms This procedure takes a few hours. Dotor will make a small cut in your groin Need to place fabric stents that come in two parts Slide 7: For the Carotid Arteries Stents are used to help keep the carotid arteries fully open after they're widened with angioplasty. For Other Arteries : For Other Arteries The arteries in the kidneys may become narrowed. (This reduces blood flow to the kidneys pressure). When aneurysms occur, they're usually in the part of the aorta in the abdomen Contras Media Inject to detect location Obstruction : Contras Media Inject to detect location Obstruction What Is a Stent? : What Is a Stent? A stent is a small mesh tube that's used to treat narrowed or weakened arteries in the body. Right coronary plaque : Right coronary plaque Slide 13: -Stents usually are made of metal mesh, but sometimes they're made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. -Some stents are coated with medicines that are slowly and continuously released into the artery. These stents are called drug-eluting stents Catheter Entrance : Catheter Entrance Catheter Entrance Via Femoralis : Catheter Entrance Via Femoralis Balloon and Stent : Balloon and Stent Sandbag Pocedure : Sandbag Pocedure The Risks of Having a Stent : The Risks of Having a Stent Angioplasty, carries a small risk of serious complications, such as: Bleeding from the site where the catheter was inserted into the skin Damage to the blood vessel from the catheter Arrhythmias (irregular heartbeats) An allergic reaction to the dye used during the procedure Infection Treating the tissue around the stent with radiation also can prevent tissue growth. PreventionYou can help to prevent coronary artery disease by controlling your risk factors for atherosclerosis to do: : PreventionYou can help to prevent coronary artery disease by controlling your risk factors for atherosclerosis to do: Quit smoking. Eat a healthy diet. Reduce your high blood LDL cholesterol ("bad cholesterol"). Reduce high blood pressure. Lose weight and exercise to prevent diabetes TreatmentCoronary artery disease caused by atherosclerosis is treated with: : TreatmentCoronary artery disease caused by atherosclerosis is treated with: Lifestyle changes. These include weight loss in obese patients, quitting smoking, diet and medications to lower high cholesterol, regular exercise, and stress reduction techniques (meditation, biofeedback, etc.). Nitrates (including nitroglycerin). These medications widen blood vessels (vasodilators). Nitrates widen the coronary arteries and increase the blood flow to the heart muscle. They also widen the body's veins, which lightens the heart's workload by temporarily decreasing the volume of blood returning to the heart for pumping. Beta-blockers, such as atenolol (Tenormin) and metoprolol (Lopressor). These medications decrease the heart's workload by slowing the heart rate and reducing the force of heart muscle contractions, especially during exercise. People who have had a heart attack should stay on a beta-blocker for life to reduce the risk of a second heart attack. Aspirin. Aspirin helps to prevent blood clots from forming inside narrowed coronary arteries. It can reduce the risk of heart attack in people who already have coronary artery disease. Doctors often advise people older than 50 to take a low dose of aspirin every day to help prevent a heart Thank You : Thank You You do not have the permission to view this presentation.
