Analysis: What Happens During A Heart Attack

Coronary artery disease (CAD) develops when plaque builds up in the narrow arteries of the heart. The arteries that are affected supply blood to your heart, oxygen, and numerous amounts of nutrients to the heart. The plaque that builds in the arteries is from the amount of cholesterol that is accumulated in the arteries. The plaque that builds within the arteries of the heart decrease the blood flow to the heart often resulting in chest pain (angina), shortness of breath, or other symptoms. This disease is often not diagnosed until the patient has a heart attack. The reason that coronary artery disease goes unnoticed is because this disease develops over decades. “Heart disease is the leading cause of

Cholesterol and fatty deposits build up in the heart's arteries, causing less blood to reach the heart muscle. The muscle becomes damaged and the remaining heart tissue has to work harder.

Coronary Artery Disease, also known as CAD, is the most common form of heart disease. (Heart and Stroke Foundation, 2009) Coronary Artery Disease obstructs the blood flow in vessels that provides blood to the heart which is caused by the buildup of plaque on the artery walls. (Rogers, 2011, p.87) (Heart and Stroke Foundation, 2009) Plaque is a yellow substance that consists of fat substances, like cholesterol, and narrows or clogs the arteries which prevents blood flow. (Heart and Stroke Foundation, 2009) Plaque can build up in any artery but usually favors large and medium sized arteries. (Heart and Stroke Foundation, 2009)

Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These

The most common heart disease that most people have is coronary artery disease. Coronary artery disease tends to cause heart attacks. When a substance of plaque builds up in your arteries, heart disease may occur. When plaque builds up, a person’s arteries can narrow over time, limiting blood flow to the heart. This could also block the blood flow. This process is called

Heart disease is formed when plaque buildup thickens and stiffens artery walls. Causing it to

Blockages cause arteries to narrow and weaken resulting in inadequate blood flow to bodily tissue, which can harm major organs that receive depleted oxygen and nutrient supplies. Plaque is surrounded by a fibrous capsule that may break with increased blood flow or narrowing arteries. Immune cells trying to repair the arterial wall may result in a blot clot that seals the area. Such repairs can cause major blockages in the coronary artery supplying the heart resulting in cardiac arrest. Blockages can occur in any region of the body including the major extremities, the heart and the brain. Restricted blood flow to the heart is known as coronary artery disease and affects the blood supply to the heart muscle, resulting in Cardiac Ischemia; characterized by decreased blood flow and oxygen to the heart muscle. These conditions similarly affect the brain in carotid artery disease and the limbs and lower body in peripheral artery disease. While cholesterol reduces the flexibility of the vessels high blood pressure can cause thinning of arterial walls due to friction and abrasions, creating weak areas. With aging it takes more effort for the circulatory system to transport blood causing arteries to become weak, encouraging plaque build up in combination with high fat

Similar to other diseases coronary heart disease affects thousands of people. The disease affects the heart in that it causes a waxy substance called plaque where it builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. When a person has coronary heart disease the hardened arteries restrict blood flow, which means that the heart cannot receive enough oxygenated blood, especially when it beats quickly during physical exertion or stress. This can cause chest pain and shortness of breath. However, if the artery is completely blocked, a heart attack can occur. Lack of oxygen during a heart attack causes damage as the heart muscle dies and is replaced with scar tissue. If damage is severe, the heart

After time of accumulation and build up the plaque it becomes hardened plaque, and the hardened plaque makes the coronary arteries narrower, which lead to reduce the blood flow to the heart muscles.

Coronary artery disease Coronary arteries are blood vessels that carry blood to the heart muscle. The coronary artery disease (also called CAD, for its acronym in English) or coronary heart disease is caused by a thickening of the inner walls of the coronary arteries. This thickening is called atherosclerosis. A fatty substance called plaque builds up inside the thickened walls of the arteries and obstructs or delays the flow of blood. If the heart muscle does not receive enough blood to function properly, you may have angina or a heart attack.

The coronary arteries supply oxygenated blood to the heart muscle. Plaque is a substance that can clog these arteries and cause a condition called atherosclerosis. The buildup of plaque can occur over many years which can ultimately lead to coronary heart disease (CHD). Plaque can harden and cause the arteries to become narrowed. This reduces the flow of oxygenated blood. Plaque may also burst and a blood clot may form causing a blockage of blood flow to the heart. In result to the blockage angina or a myocardium infarction can occur.

Coronary Artery Disease is when the major vessels supplying the heart with blood, oxygen, and nutrients become blocked, damaged, or diseased. These major vessels (arteries) can become damaged in several ways including but not limited to high blood pressure, inflammation, high cholesterol, high sugar levels, and smoking. Following the initial damage of these vessels can cause even more

Coronary heart disease occurs when plaque builds up on the walls of the coronary arteries. Blood, rich in oxygen, flows through these arteries to the heart, so when the plaque builds up on the walls, it narrows and blocks blood flow. If a blood clot forms from a ruptured plaque buildup,

The arteries get narrowed stopping the red blood cells to reach the heart. This process is is called atherosclerosis and the fatty material is called atheroma. The fatty material that builds up in the arteries is mostly low density lipoprotein (LDL) or bad cholesterol. Lipoprotein is a molecule that carries cholesterol throughout the bloodstream. Cholesterol is a fat that is produce by the liver from the saturated

Atherosclerosis is when the arteries slowly harden due to a buildup of cholesterol, fatty substances, and cellular waste, also known as plaque. Medium or large arteries can
