Atherosclerosis

CAD occurs when plaque accumulates within the coronary arteries, leading to the hardening of the vessels or atherosclerosis (USDHHS, 2016b). The build-up of plaque causes narrowing of the blood vessels, decreasing the amount of oxygen-rich blood that may pass through the arteries. Atherosclerosis eventually may lead to complete or partial blockages in the coronary arteries, causing angina or myocardial infarction (USDHSS, 2016b). Mortality rates due…

Coronary angioplasty is a medical procedure which opens up blocked blood vessels thereby restoring blood flow to the heart muscle.38 Angioplasty procedures take place at the area of thigh or the arm which is shaved to prevent the bacterial infection. The area is then cleaned with the special antibacterial agent and covered with sterile drapes to prevent infection. A numbing medication, local anesthetic drug lidocaine is injected into the skin over the blood vessel of the thigh or an arm, keeping…

What is Cardiovascular Disease? (Heart & Blood Vessels) A heart and blood vessel disease (heart disease) is multiple problems within the heart one major one is called atherosclerosis. Atherosclerosis is a heart condition caused by a substance called plaque that build up on the walls of the heart arteries. This plaque buildup can narrow the hearts arteries making it harder for blood to flow through. When this problem starts to happen it can cause clotting which is able to stop blood flow and…

Atherosclerosis can be caused by smoking, hypertension, and diabetes. Family history is a top risk factor, so can smoking, diabetes; most of the symptoms can be risk factors as well. The symptoms develop gradually, they include: chest pain, numbness in extremities…

It is caused predominantly by atherosclerosis, an accumulation of fatty deposits on the inner linings of arteries. Although coronary artery disease has also some non-atherogenic forms (e.g. arteritis, congenital coronary artery anomalies, embolism of coronary arteries, spasm of arteries or diseases of coagulation system), almost all myocardial infarctions develop from coronary atherosclerosis, generally with superimposed coronary thrombosis. [4]. During the evolution…

Case Study: The Case of the Man with the Weak Arm I. Definitions A. Essential Hypertension i. Essential hypertension is high blood pressure that doesn't have a known secondary cause. It is also referred to as primary hypertension. B. Hypercholesterolemia i. an excess of cholesterol in the bloodstream. C. Afebrile i. not feverish. D. Stroke i. a sudden disabling attack or loss of consciousness caused by an interruption in the flow of blood to the brain E. Thrombosis i. local coagulation or…

because it controls weight, and is beneficial to the mind and body. Without exercise, being inactive can lead to diseases such as coronary heart disease, osteoporosis, and colon cancer, according to Harvard researchers. Coronary heart disease, or Atherosclerosis, is a disease in which plaque, a waxy substance, is built up in the coronary arteries. Plaque can harden or break open after a while. Hardened plaque partially blocks the arteries and reduces the flow of oxygen-rich blood to the heart.…

Cholesterol is made from the liver. It is one type of lipid or fat present in the membrane of cells in the body. It is normally carried in the blood by one type of molecules known as lipoproteins. You will realize that high levels of cholesterol causes atherosclerosis and coronary artery disease (CAD).Cholesterol is a white, crystalline and fat-like substance that is often in animal food products and tissues. Cholesterol is used in repairing cell membranes, producing hormones and vitamin D. It…

Cholesterol is a powerful substance that can be produced to keep our body functioning, and it can also be found in foods. According to Dr. Maja Fiket, a medical and science freelance writer, cholesterol was first discovered in 1769, but research on cholesterol wasn’t conducted until the 20th century. In 1769, François Poulletier de la Salle discovered cholesterol in gallstones and in bile. However, Boudet, a researcher, was the first to find cholesterol in blood in 1833 (Fiket, 1). In 1928,…

Progeria is an exceptionally rare genetic disease that causes premature aging, its estimated to affect one in four million newborns worldwide. The name originated from Greek, which means “prematurely old”. This genetic disease is fatal and it comes in many forms. Children diagnosed with Progeria usually appear normal, and throughout the first two years of life the disease will start to progress. Children with Progeria are expected to live about 13 years, although there are known cases in which…
