Coronary artery disease (CAD) is a condition where the coronary artery is narrowed by fatty plaque that restricts the flow of blood to the cardiac tissues. When too little blood reaches the cardiac cells, the cells are deprived of oxygen and nutrients. Eventually, the cardiac cells die and leave permanent tissue damage. On the other hand, if blood flow is totally blocked and the cardiac tissues are deprived of oxygen and nutrients, a heart attack ensues.
Patients with coronary artery disease experience chest pain on exertion and during emotional stress but gets better with rest.
Coronary artery disease also contributes to hypertension, which may lead to heart failure.
Coronary artery disease affects the circulatory system. Chemically, this disease develops when blood vessels that are necessary for living become badly damaged. Cholesterol plaques become inflamed in the arteries. The most common signs and symptoms are chest pains which tighten the chest as if someone were standing on it. Shortening of breath also affects those with this disease because the heart is unable to supply enough blood. A major sign of this disease is having a heart attack. This indicates an artery that is completely blocked. This disease is caused by damaging the coronary arteries by smoking, diabetes, high blood pressure or high cholesterol. To diagnose this disease, medical physicians will perform physical exams and examine blood
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 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 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
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
The different types of depression are postpartum depression is when a mother that has giving birth get. Not all mothers, but some of them do. It’s also one called Seasonal affective disorder is a depression that sets in during winter and sometimes fall and that comes from the lack of sunlight. Psychotic depression is the depression that is paired with psychosis, like delusions and hallucinations. Most people that have depression may have bipolar disorder, which is called manic depression illness when having moods that are extremely high and lows. In the United States depression is one of the common mental health disorders. The National Institution of Health said that 15.7 million people in 2014 had at least one major depression stage. In the
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
Have you ever imagine a body functioning without a heart? The heart, the center of the cardiovascular system, is the essential manager for just about everything that gives the body life. Correspondingly, most of the heart diseases are fatal and cannot be ignored. In fact, "heart disease is the leading cause of death for women as well as men"(1). According to the Centers for Disease Control and Prevention, every 25 seconds someone has a coronary event(1). One of these diseases is coronary heart disease (CHD). "CHD is a condition in which certain substances builds up inside the coronary arteries"(2). When these substances block the flow of oxygen-rich blood, heart attacks most often occur. Heart attack, also known as myocardial infarction, is a serious event and a leading killer that has numerous symptoms and certain risk factors.
Cardiovascular disease has reportedly been the number one disease killer for men and women in the United States of America. Every one out of four deaths is caused by heart disease in the United States alone (Centers for Diseases Control and Prevention). Heart disease refers to the different types of conditions and symptoms that can affect the one’s heart and its functions to the body (Mayo Clinic). Cardiovascular/Heart disease has many causes and conditions, prevention methods and symptoms, and treatment options.
Coronary heart disease (CHD), also known as ischemic heart disease is the most prevalent form of cardiovascular disease in Australia. While over 20,000 of deaths in 2011 were attributed to CHD, there were estimated 590,000 Australians 18 years old and above diagnosed with CHD in 2011-2012 (AIHWAustralian Institute of Health and Welfare, 2014; Craft, 2014, p. 596).
According to the WHO, cardiovascular diseases have been the leading cause of death globally claiming 17 million lives a year, more deaths than all cancer combined (Chiu and Radisic, 2013). Cardiovascular disease is responsible for a preponderance of health problems and its impact is expected to grow further as the population ages. In the UK, NHS spends about £7.74 billion as the expenditure to deal with cardiovascular diseases (Barton et al., 2011). Cardiovascular disease in the form of myocardial infarction has become the principle cause of death in developed countries, accounting for nearly 40% of all deaths (http://www.bhf.org.uk/). Congenital heart defects, which occur in nearly 14 of every 1000 new-born children, is another tragic fact that baffles medical industry (http://www.heart.org/). About 61 million Americans (almost one-fourth of the population) live with cardiovascular diseases, such as coronary heart disease, congenital cardiovascular defects, and congestive heart failure.
CAD is an artery disease where the blood vessels that supply blood to the heart becomes hardened or narrowed due to the build-up of cholesterol and plaque in the inner wall; this causes a reduced blood flow to the heart muscles. Hence, if the arteries become severely narrowed or blocked, the heart becomes deficient for nutrients and oxygen.
As with most controversial issues, it is clear that the media play a strong role in people’s perception and fear of crime. Psychologists have proven that cognitive biases can skew our perceptions (Fogg, 2013). Crime is very prominent is all media and Robert Reiner (1997) claims:
The gods often turned their backs on warriors, completely dependent on their defeats. A god would cling to their favored hero; cherish them, guard them, some even going to the extent of recusing them from death itself. In order to survive, warriors were required to honor the gods, enabling them leniency toward even the crudest of rages. Judging by the gear sported by both, one can see the potency flowing, the sign of a great warrior. Thus, Achilles and Penthesilea must have had a moderately decent relationship with the gods. This relationship would rescue the two from eminent death as well as gift both with a life unafraid of the god’s fury; a life unquestionably worth
Coronary heart disease is caused by the narrowing of the coronary arteries which is because of the deposition of fats and cholesterol on the inside lining of the arteries. These deposits which also cause hardening of the walls of the arteries also block the flow of oxygen to the heart. This deprives the heart of the needed oxygen that is required for its proper functioning.
