A numerical simulation and visualization of blood flow through a stenosed artery with the different severity

Abstract

The cardiovascular system consist of the heart and blood vessels that carrying blood in whole human bodies. The heart is a vital organ in the human body. The heart disease is the most common chronic disease of the coronary arteries is called atherosclerosis. Atherosclerosis occurs when a build-up of plaque or cholesterol deposits on artery walls. Over time, plaque can accumulate, harden and narrow the arteries and impede blood flow to the heart. Coronary artery disease or coronary artery disease (CAD) is the basically can caused heart attacks, strokes, various heart disease including congestive heart failure and most cardiovascular disease in general. A blockage in one or more coronary arteries can cause heart attack suddenly. In addition, diseased arteries also tend to experience sudden muscle contractions. Thus, a piece of a blood crust can form a contraction, release chemicals which then result in narrowing the artery wall, triggering a heart attack. If the working system of the heart is damage, the normal rhythm of the heart can become chaotic and the heart began to tremble with uncertainty or experiencing fibrillation. This abnormal rhythm known as arrhythmia is a deviation from the normal heart rhythm. This will cause the heart’s ability to pump blood effectively to the brain.
