Coronary artery disease

healthy heart. Conditions that overstrain the heart muscle can lead to heart failure (5). The main causation of chronic heart failure is a heart attack which results in damage to the muscle of the left ventricle (8). In addition cardiomyopathy (chronic disease of the heart muscle) may cause heart failure; this may perhaps be initiated by a viral infection (1).Conditions such as hypertension (high blood pressure) and arrhythmia (irregular rate or rhythm of heartbeat) could also contribute to the…

Observation: The cardiovascular system is responsible for getting the constant supply of oxygen the body needs to the tissues that need it. It also helps removes carbon dioxide, a waste product, from tissues and transports it to the lungs where it's removed when breathes out. Since the cardiovascular system’s roles are vital, people need to take good care of their hearts in order to maintain a healthy lifestyle. The purpose of this investigation is to determine whether teenagers can improve…

Cardiovascular Disease “Eisenmenger Syndrome” Eisenmenger Syndrome is a rare cardiovascular disease that was named after the person who first described it in 1897, Victor Eisenmenger (Davis, 2017, p. 765). According to the article “Eisenmenger Syndrome in Children” by Ayden and Brass (2017), it is considered an “advanced form of Pulmonary Hypertension.” Pulmonary Hypertension is where the “arteries that carry blood from the heart to the lungs become narrow.” When these arteries become narrow,…

carefully in the home; the care team provided instructions to Jill on how to store the oxygen correctly. See appendix 2 for side effects and more information about oxygen. Fortunately, Jill was a non-smoker and her four litres of oxygen seemed to be working for her. Unfortunately, Jill was overweight at 115 kg which had to be addressed and probably assisted in the maturation of her CHF. Furthermore, it did not help with her shortness of breath as moving around with her physique was not easy and…

Malignant mesothelioma is considered as an aggressive form of cancer and giving out accurate prognosis is not that easy. Prognosis for patients diagnosed with malignant mesothelioma is somehow discouraging since it has a long latency period. In most cases, it is only identified when it is in a radical stage already. What is malignant mesothelioma? It is a rare tumor of mesothelial cells and it mostly affects the pleura (the lining that shields the lungs). Most people diagnosed with…

often take a nitroglycerin tablet to relieve their symptoms. How does this relieve their symptoms? In your answer discuss (briefly) oxygen delivery to the heart. (3 points) Chronic angina can occur when there is a blockage or restriction in the arteries of the heart causing pain because of the lack of oxygenated blood flowing to the heart. The pain associated with chronic angina can become worse during exercise, when the heart is working harder, and better during rest, when the body requires…

Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it. An ischemic stroke and a transient ischemic attack are both caused by a blockage in the artery that supplies oxygen rich blood to the brain, these are the most common types of stroke. With a…

Pericarditis A. Etiology – The most common causes of pericarditis are either that it is idiopathic (unknown origin), or due to a viral infection. Other causes include: trauma, a myocardial, infarction, other types of infection, or other inflammatory conditions. B. Pathophysiology – This pathology is the inflammation of the pericardium of the heart. This inflammation causes narrowing of the pericardial space, which may also cause scarring. If left untreated this may lead to pericardial effusion,…

pressure that is 140 over 90 or higher is considered too high and unhealthy. This level will damage vessel walls over time, leading to very serious health issues. Risk Factors Secondary Hypertension is high blood pressure, which is caused by a disease, however most people who suffer from high blood pressure, suffer from essential or primary hypertension. The exact cause of this is unknown although the theories involve several mechanisms. Risk factors include: * High blood pressure in…

Life or Death? A fourteen year old boy was undergoing surgery when his heart suddenly stopped. Otherwise known as cardiac arrest. Cardiac arrest is when the heart stops all electrical activity, eventually stopping the heart muscle from contracting. When the heart stops beating, the whole body including the brain does not receive oxygen. If the brain lacks oxygen for, ten to fifteen minutes, there could be permanent brain damage. It is crucial that the heart starts beating or someone starts…
