A Brief Note On Atherosclerosis And Its Effects On The...

1. MYOCARDIAL INFARCTIONS Atherosclerosis impairs proper perfusion through ischemia and has acute and long-term serious consequences on the body’s vasculature including unstable and stable angina, myocardial infarctions, sudden cardiac death, transient ischemic attacks, cerebrovascular disease and more. The most common cause of myocardial infarctions (MI) is ischemic heart disease, and in turn, MIs are one of the leading causes of heart failure because they directly alter the structure and function of the heart. Heart failure can be described as the inability of the heart to adequately fill or contract in order to meet the body’s metabolic demands. MIs affect the ability of the heart to properly fill and eject blood depending on the location and extent of infarct. The adrenergic response and renin-angiotensin aldosterone system (RAAS) both play a vital role in the regulation of heart rate and stroke volume. In the short-term, the death of myocardial cells due to occlusion and lack of oxygen and nutrients leads to overall decreased muscle cells, decreased stroke volume, and thus decreased cardiac output. Following an MI, cell death, inflammation, and neurohormonal mechanisms contribute to cardiac remodeling which has long-term detrimental consequences. Initially, persistent ischemia directly leads to cardiomyocyte loss from necrosis and apoptosis. Furthermore, inflammatory cells and their mediators such as the pro-fibrotic cytokines TGF-B1 and CTGF begin to clear necroticShow MoreRelatedA Brief Note On Atherosclerosis And Its Effects On The Heart Essay1138 Words   |  5 Pagesof the disease Atherosclerosis is a disease dealing with the heart. This disease causes hardening and narrowing (or even blockage) of the arteries, which makes the arteries thicken. Accumulations of fat, calcium and plaque build up are all components of having this disease known as atherosclerosis. The accumulations of calcium, fat, and plaque build up quietly and slowly block the arteries, putting blood flow at an extremely high risk. Atherosclerosis is typically the source of heart attacks, strokesRead MoreErectile Dysfunction ( Ed )1017 Words   |  5 Pagescom/erectile-dysfunction/rm-quiz-erectile-dysfunction ED is a very common sexual dysfunction, is occurs in men. The chances of ED increase with age, however, it is not an unavoidable part of aging. ED can be inability, inconsistent ability or able to maintain brief period of erection that is firm enough for sexual intercourse (Arcangelo, 2013). ED can increase stress, decrease self-confidence and leads to relationship problems. It could be the initial signs and symptoms of other health issues (Mayo Clinic, 2016)Read MoreThe Cardiovascular System Of Atherosclerosis3729 Words   |  15 Pagesconstantly being pumped to and from the heart through arteries and veins, respectively. Oxygen, nutrients, water, wastes are just some of the substances moving throughout the body via the blood vessels. Because this system is very complex, many issues can occur which inhibit the cardiovascular system from doing its job. Cardiovascular disease (CVD) is a category of diseases that relate to the heart and blood vessels. The most common form of CVD is coronary heart disease and involves the buildup plaqueRead MoreMyocardil Effusion4228 Words   |  17 PagesNMC (2008) code of conduct, the name of the patient will be changed to Peter and the placement area will remain as an acute care setting. According to McFerran (2008) the term â€Å"acute† is described as a disease of rapid onset, severe symptoms, and brief duration. Acute Care refers to riding at a crossroads of coming sharply to a crisis; severe, not chronic (Allen, 2000). Acute problems may appear precipitously, striking a totally unsuspecting victim.

Ischaemia is a term which is used to describe the deficiency in blood supply to any part of the body. In ischaemic heart disease there is a deficiency in the blood supply to the heart muscle which can be caused by an obstruction to, or even a narrowing of the coronary arteries. This in turn reduces the supply of nutrients and oxygen to the heart muscle. Without an optimum oxygen supply the heart muscle is unable to functionRead MoreCase Study Essay33967 Words   |  136 PagesPART ONE Medical-Surgical Cases 1 1 Cardiovascular Cardiovascular Disorders Case Study 1 Heart Failure Difficulty: Beginning Setting: Emergency department, hospital Index Words: heart failure (HF), cardiomyopathy, volume overload, quality of life X Scenario M.G., a â€Å"frequent flier,† is admitted to the emergency department (ED) with a diagnosis of heart failure (HF).
