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

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

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

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

Carotid Artery Disease and Stroke Oxygenated blood is carried from the heart to the face and brain by the carotid arteries one on each side of the neck. The carotid arteries (common) bifurcate and become the internal carotid artery (ICA) and the external carotid artery (ECA). Blood supply to the brain is mainly through the internal carotid artery and the vertebral arteries (1). Blood flow to the brain is affected by carotid artery disease. Carotid artery disease is the narrowing (stenosis) or

states that “more than a million persons in the U.S. have a heart attack and about half (515‚000) of them die in each year. About one-half of those who die do so within 1 hour of 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

Rizal was not the leader of the revolution Rizal condemned about the idea of revolution. Thou he was not the leader

Coronary arteries supply the heart with a constant supply of blood. These arteries are essential‚ providing oxygen and nutrients that keep the heart constantly pumping. Arteries have three layers including the external layer‚ tunica external‚ middle layer‚ tunica media and the inner layer‚ called the tunica intima. The outer layer is made up of connective tissue with elastic and collagenous fibers. Tunica media is the thickest layer composed of smooth muscle and can change the diameter of the arteries

A varicose vein is a superficial vein with a faulty valve. The calf muscles squeezes the deep veins in the leg and pressure is reduced in the superficial veins. These superficial veins are fitted with special one-way valves to prevent the blood running backwards. The weight of blood in the vein is conciderable especially while standing still and the blood flow is against gravity. and blood is allowed to pool stretching the walls of the veins which damage the valves resulting in the lumen being unable
