...Coronary artery disease is usually caused by atherosclerosis. Cholesterol and other fatty substances accumulate on the inner wall of the arteries. This attracts fibrous tissue, blood components, and calcium, which harden into flow-obstructing plaques. If a blood clot suddenly forms on one of these plaques it can convert a partial obstruction to a total occlusion. When the blockage is temporary or partial, angina (chest pain or pressure) may occur. When the blockage completely and suddenly cuts off the flow of blood, the result is myocardial infarction. Congenital defects and spasms of a coronary artery may also block blood flow. There is evidence that infection from organisms such as chlamydia bacteria may be responsible for some cases of coronary artery disease. A number of major contributing factors increase...

...Coronary heart disease (CHD), also called coronary artery disease, is a condition in which plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). The buildup of plaque occurs over many years. Figure A shows a normal artery with normal blood flow. Figure B shows an artery with plaque buildup. Over time, plaque hardens and narrows your coronary arteries. This limits the flow of oxygen-rich blood to your heart muscle. Eventually, an area of plaque can rupture (break open). This causes a blood clot to form on the surface of the plaque. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.

...Coronary artery disease is when the arteries that supply blood to the heart muscle become hard and narrow, causing the heart to be deprived of blood and oxygen. Managing coronary artery disease can be difficult and stressful for some patients. Research about this topic is commonly explored and has positive reviews when management interventions are implemented. There have been patients who have benefited from different behavioral and pharmacological techniques that produce healthy outcomes. However, patients do not have the knowledge or resources to obtain the correct information on their own. Nurses, as advocates, should educate patients on proper care of this illness.

...Coronary Artery disease (CAD) is arguably the world’s most deadly disease. With upwards to 3 million new cases every year, the disease is still without a cure and has a death rate of nearly 25%. This disease is the number 1 cause of death in men and women with 615,000 men and women afflicted with this disease and another 735,000 men and women suffering from a heart attack caused by CAD. Coronary Artery Disease is a disease in which plaque builds up inside the arteries. The buildup of plaque in the arteries causes a narrowing of the arteries. This results in the inability of the blood containing necessary oxygen to be transported to the heart and thus, to the rest of the body. The arteries are supposed to normally supply oxygen to the heart...

...Title OVERVIEW Coronary artery disease (CAD) is a condition that is caused by plaque build-up in the arteries to the heart. The plaque creates a blockage in those arteries, decreasing the amount of blood flow and oxygen that the heart needs to function properly (Julian et al. 1998, as cited by Tully, Baker, Turnbull, & Winefield, p.281). Coronary artery disease is one of the leading causes of death worldwide. Heart catheterizations, stent insertions, valve replacements, and coronary artery bypass grafts (CABG) are types of surgical interventions used to repair heart damage. Today, cardiac surgery is a common event, but for the person undergoing the procedure, depression and anxiety can play a large role in the recovery process. When the patient learns he must have heart surgery, many feelings and emotions come...

Over 6 million Americans gain symptoms due to coronary artery disease and about 1/3 die from it. One must meet with many different types of doctors in order to get an accurate result. One of them is a cardiologist that is meant to diagnose heart diseases and conditions depending on the area of the heart that you are in. Another doctor you can see is a vascular specialist, who is meant to diagnose blood vessel problems. These doctors will do physical examinations where they will use a stethoscope to check the arteries for any seething noises such as a bruit due to plaque buildup. They may also...

...The Deadliest Disease in the World Coronary artery disease (CAD) is the most deadly disease in the world. CAD occurs when plaque builds up in the arteries causing blood clots and restricting the heart of oxygen. CAD is the number one cause of death in the United States and the world. Medications and treatments are available but nothing can take the place of being proactive and preventing the disease. ("What Is Coronary Heart Disease?") Coronary artery disease is caused when cholesterol containing deposits of plaque buildup inside the arteries that supply blood to your heart. As the plaque builds up, it begins to narrow your arteries, decreasing the amount of blood flow to your heart. The plaque often attracts other fibrous tissue such as calcium and blood components which further harden the artery by causing blood clots to form. Over time, the decreased blood flow will cause shortness of breath, chest pain and even heart attack. ("What Is Coronary Heart Disease?") According to the center of disease control, heart disease is the number 1 cause of death in the United States, killing over 780,000 people every year. Specifically, coronary artery disease is responsible for killing over 380,000 people per year.

...Dr.Giselle Salgado-Jimenez June 18, 2015 Coronary Artery Disease Heart disease The topic I will explore is Coronary Artery Disease or Heart Disease in women. My question, what do healthcare providers need to know about heart disease in woman and how it is different from men will be discussed. Coronary Artery disease is the leading cause of death in woman and men in society. Many women’s risk factor goes unrecognized and untreated by their primary doctor (Pregler et al., 2009). According to familyDoctor.org, “American women are 4 to 6 times more likely to die of heart disease that of breast cancer” (2009). In generally men have an earlier onset of heart disease than to woman but have a higher survival rate from heart attach than do woman (Dzugan, 2005). Heart disease can take many forms. Different arteries supply different areas of the heart with oxygenated blood. If one or more of these arteries became narrowed or clogged as a result of coronary artery disease, or atherosclerosis the artery cannot fully supply the part of the heart it is responsible for. The heart is an effective pump only when good blood supply is maintained to all heart muscles. Most women are not aware that heart disease is a greater risk for them than breast or cervical cancer. My research has shown that women in general have a lack of knowledge of heart disease and its deadly risk.There is numerous risk factors that contribute to the risk to heart disease. Risk can be categorized into no modifiable...

The topic of heart disease usually centers on heart attacks but there are many other problems that can compromise heart functions, injure the heart tissues, or cause heart disease. Most of the major problems include coronary artery disease, heart failure, arrhythmias, and cardiomyopathy. The following slides will present these heart problems and their warning signs 2.Heart disease facts Heart disease refers to several conditions that affect the heart and blood vessels. Arrhythmias, heart valve disease, congenital heart defects, and inflammation of the heart or its lining (the pericardium) are all diseases that affect the heart. However, this article will focus on the most common type of heart disease, coronary artery disease (CAD), also known as atherosclerotic heart disease (ASHD). Coronary artery disease is the most common cause of death in the United States. Over a million people each year will have a heart attack and 25% will die before they get to the hospital while or in the Emergency Department. Prevention is the key to treatment of heart disease. Diagnosis of heart disease is often made by careful history taken by a health care practitioner. Some individuals may have atypical symptoms, including almost none at all. The testing strategy to confirm the diagnosis and plan appropriate treatment needs to be individualized for each patient diagnosed with heart disease. Treatment of heart disease depends...

...Coronary Heart Disease Coronary heart disease is the most common of heart diseases. Nearly 500,000 Americans die each year from CHD. This type of heart disease is caused by narrowing or clogging of the coronary arteries. CHD is the number one killer in both men and women in the U.S. these deaths could be prevented because CHD is related to certain aspects of one’s life. The risk factors include high blood pressure, smoking, high cholesterol, obesity, and no physical activities- all of which can be controlled. The heart needs a constant supple of nutrients and oxygen that is supplied by the blood that is carried to the coronary arteries. When the coronary arteries become clogged or narrow and cannot deliver enough blood to the heart, the result is CHD. When there is not enough blood reaching the heart, the heart will respond with pain call angina. This pain is usually felt sometimes in the left arm and shoulder or in the chest. However sometimes there are no symptoms, which is a condition called silent angina. Once the blood supply is cut off completely the results are a heart attack. CHD is the result of a process known as atherosclerosis. Atherosclerosis occurs when a person has fat like substances in the blood. This process is caused by a thickening which narrows the arteries over time by deposits of plaque. Plaque is a buildup of materials such as: * Cholesterol * Fats * Platelets * Cell wastes * Calcium At a young age plaque can start to deposit in...
