carotid arteries. So why do an estimated 700‚000 people get carotid artery disease each year‚ And why do more than 130‚000 people die of strokes each year?1 these questions will be answered in order to provide a better understanding of the carotid arteries and their importance. [change slide] Oxygenated blood is carried from the heart to the face and brain by the carotid arteries‚ one on each side of the neck. [change slide] The carotid arteries bifurcate and become the internal carotid artery (ICA)

Coronary artery disease (CAD) is a progressive disease that causes narrowing or occlusion of the coronary arteries‚ causing a decreased blood supply to the myocardial layer of the heart‚ and prevents the arteries from dilating. As a result the tissue is deprived of oxygen necessary to thrive‚ which in turn can lead to myocardial ischemia‚ leading to several types of infarctions. Depending on the area of the ischemia‚ there can be several complications. For example‚ a ST segment elevation myocardial

ABSTRACT Coronary artery disease (CAD)‚ also known as coronary heart disease (CHD) or coronary atherosclerosis‚ involves the progressive narrowing of the arteries that nourish the heart muscle. Often there are no symptoms‚ but if one or more of these arteries become severely narrowed‚ angina may develop during exercise‚ stress‚ or other times when the heart muscle is not getting enough blood. Your coronary arteries are the major blood vessels that supply your heart with blood‚ oxygen and nutrients

Pd. 6 Coronary Artery Disease Coronary heart disease (CHD)‚ also called coronary artery disease‚ is a condition in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. This plaque is made up of fat‚ cholesterol‚ calcium‚ and other substances found in the blood. When plaque builds up in the arteries‚ the condition is called atherosclerosis‚ the buildup of plaque occurs over many years. Over time‚ the plaque hardens which causes your coronary

Peripheral Artery Disease and Risks The common cause of peripheral artery disease (PAD) is atherosclerosis. Less common causes of peripheral artery disease may be blood vessel inflammation‚ injury to your limbs‚ unusual anatomy of your ligaments or muscles‚ or radiation exposure (Mayo Clinic‚ 2016). The risk factors for PAD are the same as those for atherosclerotic disease; they are smoking‚ hypertension‚ diabetes‚ increased levels of low-density lipoprotein (LDL)‚ decreased levels of high-density

There are several good reasons to consider having your varicose veins removed. The most popular reason is appearance. Unless your legs and ankles are covered with clothing all of the time‚ your varicose veins will show. If they are severe‚ you may feel self-conscious and conceal your legs. This is the number one reason people want to remove their varicose veins. Varicose veins develop because the veins become weak and do not function properly to push the blood up the legs‚ against gravity back to

Background to product Artery aid is a new innovative product that is designed specifically to treat sufferers of peripheral arterial disease. Artery Aid was inspired by personnel experience within the group. Kate‚ one off the members of Artery Aid‚ has witnessed the effects of peripheral artery disease first as her own mother suffered from the disease. This is what first inspired our product. The two main methods of treating peripheral artery disease are exercise and heat. Exercise works by working

Pulmonary Artery Catheterization Pulmonary artery catheterization is a procedure that is done to test blood movement through the heart and to monitor the heart’s function. In this procedure‚ a thin‚ flexible tube (catheter) is passed into the right side of the heart and into the main artery that carries blood from your heart to your lungs (pulmonary artery). The procedure may be done to evaluate or help diagnose various problems‚ such as: • Heart failure. • Shock. • Leaky heart valves (valvular

Investigating Projectiles Background: A projectile is an entity which only has the force of gravity acting upon it. A projectile can be cast‚ fired‚ flung‚ heaved‚ hurled‚ pitched‚ tossed and thrown. A projectile can be anything as long as it has initial horizontal velocity that is not equal to zero which has the acceleration due to gravity. Projectile motion happens when an object projected with a force stops putting influence on the object after its launched‚ hence the only force being gravity

the start of symptoms and before reaching the hospital”. A heart attack happens to a person when the blood flow and oxygen supply to heart muscle is blocked‚ and it is mostly caused by the Coronary Artery Disease (CAD). CAD occurs when the arteries that supply blood to the heart muscle (coronary arteries) become hardened and narrowed. It often causes irregular heart beat or rhythm by blocking blood stream. The National Heart‚ Lung‚ and Blood Institute suggest that “everyone should know the warning
