Pathophysiology of Coronary Artery Disease Atherosclerosis is a type of arteriosclerosis caused by a build-up of plaque in the inner lining of an artery. (Arteriosclerosis is a general term for thickening or hardening of the arteries.) (Porth 2005) Plaque is made up of deposits of fatty substances‚ cholesterol‚ cellular waste products‚ calcium‚ and fibrin‚ and can develop in medium or large arteries. The artery wall becomes thickened and looses its elasticity. (Fraser 2000) The wall of an artery

Answer: one piece of interesting information I found in the introduction was that‚ low-density lipoprotein cholesterol (LDL) has been shown to be the most predictive of atherogenic susceptibility6 and has been demonstrated to exhibit oxidative susceptibility‚ which then relates to pathogenic oxidative processes implicated in coronary atherosclerotic plaque progression

CARDIOVASCULAR FITNESS Cardiovascular fitness is frequently considered the most important aspect of physical fitness because those who possess it are likely to have a lessened risk of coronary heart disease – the number one killer in our society. Cardiovascular fitness is also referred to as cardiovascular endurance‚ cardio-respiratory capacity and circulatory fitness. Regardless of the word used to describe it‚ cardiovascular fitness is complex because it requires fitness of several body systems

cardiovascular system consists of : heart (심장)‚ and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins leading from

High blood cholesterol is a condition that greatly increases your chances of developing coronary heart disease. Extra cholesterol in the blood settles on the inner walls of the arteries‚ narrowing them and allowing less blood to pass through them to the heart. Aim for total cholesterol below 200 mg/dL; LDL cholesterol below 130 mg/dL and HDL
