Cornary artery disease

Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for

Coronary Artery Disease (CAD) is a type of heart disease where plaque accumulates in the coronary arteries, which provide blood to the heart. The plaque is made of cholesterol deposits, and when it builds up in the arteries, it causes the arteries to slowly narrow (atherosclerosis). A very common symptom of CAD is angina, which is caused by the buildup of plaque. Angina is chest pain that is caused by reduced flow of oxygen rich blood to the heart. This makes the heart muscle weak, and can lead to another symptom of CAD, arrhythmia. Arrhythmia is an irregular heartbeat. However, sometimes these symptoms don’t show up at all. The first indication of CAD in some people is a heart attack. A heart attack is when a plaque buildup blocks an artery completely and thus, stops blood flow to the heart.

Coronary artery disease (CAD) is when the arteries that supplies blood for the heart muscle gradually hardens and thickens (artherosclorosis) because of the buildup from salt, fat, cholesterol and other substances (plaque) on their inner walls. This process leaves the heart with a lack of oxygen and blood, forcing it to work harder (high blood

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.

According to the National Heart, Lung and Blood Institute (NHLBI), Coronary heart disease is a cardiovascular disease caused by a cholesterol substance termed plaque, accumulating within the coronary arteries, which is where oxygen-rich blood is delivered to the heart. Progressively, the flow of oxygen to the heart will suffer if hardened plaque begins to narrow the coronary arteries. Furthermore, blood clots could occur upon the surface of plaque if it ruptures. Large blood clots will incapacitate blood flow through the coronary arteries. As a result, angina or a heart attack may follow plaque-blocked oxygen-rich blood flow. The NHLBI refers to CHD as a progressive disease where a destabilised heart can lead to conditions such as heart failure

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)

Taking action to the risk factors of arteriosclerosis can prevent or delay the disease. The risk of arteriosclerosis increase with the number of risk factors you have. A big step of arteriosclerosis prevention is to live a healthy lifestyle which includes:

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

Coronary Heart Disease (CHD) it is also know as Coronary Artery Disease. It happens when the blood vessels delivering to the heart develop blockage or are narrowed by plaque, which reduces the flow of the blood, oxygen and nutrients supplied to the heart. If this happens the person starts to feel chest pain (also known as angina pectoris) and then it lead to the person to have a heart attack. It is known to be the main factor to cause cardiac arrest and it can be fatal unless the heart is restarted in minutes.

Coronary artery disease is one of the common forms of heart disease. It’s caused by the narrowing occurs in the coronary arteries so that reduces the flow of blood to the heart tissues. Through the artery is gradually narrowing because of a substance called plaque builds up inside the wall of coronary arteries, the heart may not get enough blood to work. (coronary artery disease)If the plaque ruptures, a blood clot can form around on its surface. Over the time, the blood clot can completely block the pathway, which can’t let any blood to go through.

Coronary artery disease (CAD), also known as coronary heart disease, is the leading cause of mortality in both men and women in the United States today. It has been reported by the Centers for Disease Control and Prevention that CAD accounted for nearly 616,000 deaths in 2011 and was responsible for 1 in 4 deaths in the U.S. in the same year. 1 Coronary artery disease is a progressive disease where the major arterial vessels supplying the heart become occluded and sclerotic due to the buildup of plaque in the inner walls of the artery through a process called atherosclerosis. 2 CAD eventually leads to heart failure and a myocardial infarction (MI).

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.

Cardiac arrest is a grave medical emergency where the heart stops pumping blood throughout the body and can lead to death in minutes. There are currently 30,000 out of hospital cardiac arrest in UK (Perkins, 2016). In coronary artery disease there is a obstruction in the arteries that supply blood and oxygen to the heart. The initial step in coronary artery disease (CAD) is the formation of atherosclerosis. The build up of plaque is called atherosclerosis. CAD is a progressive disease that most commonly presents as angina. The beginning of CAD is thought

Heart disease causes almost thirty percent of elderly death each year and caused twenty-five percent of all deaths in 2008 (cardiosmart), yet despite its high death rates, we often are not taught the preventative measures before it is too late. While some risk factors of cardiovascular disease are uncontrollable (such as genetics, race, and age) many can be reduced through lifestyle changes. It is important to understand the risk factors, prevention methods, and types of cardiovascular disease.

Men older than age 45 can get coronary artery disease and women over the age 55 can get the disease as well because they can have a history of early heart disease. Some risk factors can also be High blood cholesterol levels (low-density lipoprotein cholesterol),High blood pressure, Cigarette smoking, Diabetes mellitus, Obestiy, Lack of physcial activity, Metabolic syndrome, and Mental stress and depression. There are also some non traditional risk factors like C-reactive protein which can cause inflammation and can also casue a heart attack, Lipoprotein, Homocysteine, Small dense LDL-C proteins and Fibrinogen. The coronary aretery disease starts with growth within the walls of the coronary arteries until the blood flow of the heart muscle is limited which is also
