Atherosclerosis: The Wall Of The Barrier

Improved Essays
Atherosclerosis: Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries, reducing blood flow to your organs (such as your heart) and other parts of your body. This can lead to serious problems, including heart attack, stroke, or even death

Atherosclerosis is an inflammatory disease of the wall of large- and medium-sized arteries that is precipitated by elevated levels of low density lipoprotein (LDL) cholesterol in the blood. Although dendritic cells (DCs) and lymphocytes are found

    Figure 1 outlines the coronary arteries on the heart which supply the cardiac muscles with nutrients such as oxygen and glucose needed to survive [1]. Like any organ in the human body, the heart needs a constant supply of blood. Over time, fatty deposits can build up and form an atheroma on the artery lining. An atheroma is a hardened plaque caused by accumulated fatty deposits and scar tissue [2].…

    John’s doctor is rightfully concerned for him. Having high total cholesterol, LDL, and triglycerides can indicate a higher likelihood of developing cardiovascular disease. From class, I’ve learned that elevated or too much cholesterol, in particular, can lead to atherosclerosis a condition that entails formerly healthy arterial walls becoming thickened with excess deposits of cholesterol and other substances which is collectively referred to as arterial plaque. This plaque within the walls acts to restrict blood flow within the artery, which can eventually lead to blood clots that result in…

    Explain how atherosclerotic plaque is formed. Atherosclerosis is a disease of the large and intermediate sized arteries, where fatty lesions called atheromatous plaques develop on the inside surfaces of arterial walls. It is characterised by endothelial dysfunction, vascular inflammation and an accumulation of lipids, calcium, cholesterol, and cellular debris within the intima wall - making it a multifactorial disease that usually develops many years before manifestation of clinical symptoms. Stages of plaque formation 1.Fatty streak development…

(10 points) Coronary artery atherosclerosis is most commonly comprised of atherosclerotic fibrous fatty obstructions of the large epicardial vessels, which provide for blood flow and transport nutrients, oxygen, and elimination of metabolic waste products such as CO2, lactic acid, and hydrogen ions. Coronary artery atherosclerosis is a progressive disease related to and accumulating atheroma (fibrous fatty plaque), which damage the supporting vessels of the heart and eventually progress to cardiac complications such as angina pectoris, MI, heart failure, and extracardiac complications.…

    Over the time excessive cholesterol build up in the blood vessels and results in the blockage of blood flow. This blockage reduce required amount of oxygen body need for proper functioning and could leads to heart attack, stroke and deep vein thrombosis.

A high level of LDL cholesterol accumulate within the blood vessel and hardens and narrow the passage. HDL is good lipoprotein which clear the excess the cholesterol in the blood vessels.…

    Though heart failure can occur suddenly, weakening of the heart is more likely to slowly develop over a period of time, often over many years as the heart becomes weaker and is unable to work as efficiently, which is why is it more prominent in the elderly population. Typically conditions and diseases that damage or overwork the heart lead to congestive heart failure. The major conditions and factors that cause congestive heart failure include: • Coronary artery disease • Heart valve disease • High blood pressure • Hypertension • Valve conditions • Cardiomyopathy • Diabetes • Alcohol abuse • Smoking Coronary artery disease, also known as ischaemic heart disease, results from the gradual blocking of the coronary artery by fatty deposits called plaque. The coronary artery is the artery that supplies blood to the heart, damaging it…

    Hypertension also referred to as blood pressure, it 's the force pushing against the walls of arteries as it flows through them, (Medical Dictionary, 2016). When the heart beats to push out blood from the arteries blood pressure is at its highest. Hypertension sometimes called “Silent killer” because patients can live with the condition for years without any signs and symptoms. Systolic is the first blood pressure reading, it is when the heart is contracting while diastolic is the second blood pressure reading when the heart is relaxed. There are various stages of hypertension : Prehypertension ( with a systolic reading between 120-139 and a diastolic reading between 80-89) High blood pressure stage1 (with a systolic reading between 140-159 and a diastolic reading between 90-99).…

    Discovered in 1913 by a man named Nikolai Anichkov, atherosclerosis is a disease where things like calcium and fat build up in the arteries and block blood flow. Arteries harden as a result of it, and it’ll cause problems transferring blood around the body. The plaque will form a barrier, and can cause serious problems in the body, like other diseases and disorders. The results are possibly deadly. There is a layer on the inside of every vein that keeps it smooth called endothelium.…
