Cardiovascular Disease, The Major Problem Of New Zealand For Years Essay

Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis. Atherosclerosis is the narrowing and thickening of arteries and develops for years without causing symptoms. It can happen in any part of the body. Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease. The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack. (World Heart Federation).

The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.

The cardiovascular system, however, would not be able to effectively complete these functions without help from what is sometimes referred to as the body’s hardest-working organ- the heart. Approximately the size of a fist, the heart is contains four chambers (the uppermost are called the atria and the lowermost are called the ventricles) and four valves. Additionally, the heart is surrounded by the pericardium, a structure that serves to protect the heart, keep the heart stabilized in the chest, and

Cardiovascular disease (CVD) is a major cause of death and disability in the United States among adults. More than one-half of all deaths were caused by heart disease, cancer or

Nevertheless, there is an understandable and noticeable link between circulatory related diseases and lifestyle diseases, such as Coronary Heart Disease. Coronary heart disease can occur when fatty acids, such as cholesterol in an inadequate diet, build up in the walls of the coronary artery. These fatty deposits collect minerals and harden to become a plaque. Eventually, this plaque grows and can swells up, forming an aneurism. In some cases, this aneurism may burst leading to instant death. As it continues to grow and swell up, it finally blocks the artery completely and forms blood clots. This is known as coronary thrombosis. A myocardial infarction, or in other words as heart attack, occurs when no oxygen is able to reach the coronary artery and thus it is unable to fulfil its role in providing the heart muscle with a sufficient supply of blood. Heart attacks are very common in the society nowadays, especially occurring in smokers or obesity related diseases (Millar, June 2014)

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

Coronary illness is the development of plaque (fat store on the inward dividers of the veins) in the coronary conduits that supply O2 rich blood to the heart muscle, the development of plaque is called atherosclerosis. After some time passes plaques may solidify therefore limiting blood stream or totally obstructing the corridor. The development of plaque is straightforwardly identified with a people way of life, normal danger elements incorporate stoutness, high blood cholesterol and diabetes. At the point when the endothelium is harmed by blood stream, the cholesterol and fats in the blood get stuck shaping plaques. This outcomes in hypertension due the heart endeavoring to supply obliged levels of blood to the body. In the event that the blood stream to the heart muscles is limited or blocked it may

According to Centers for Disease Control and Prevention, Cardiovascular disease (CVD) is the leading cause of death in the world, responsible for 30% of all deaths globally (WHO) 1 -3 deaths in the U .S. (CDC).

The heart is a complex yet delicate organ that operates the body on a regular basis. Without the heart the circulation system within the body would cease to exist; therefore, we would cease to exist. As with everything that is complex and works around the clock there are certain issues that can arise for example, atrial fibrillation. Atrial fibrillation is the result of an irregular or fast heartbeat this will often cause an inadequate circulation throughout the rest of the body. The atrium of the heart will not sync up to the ventricles causing an irregular or fast heartbeat.

The heart is one of the main organs of the human body which is responsible for pumping blood throughout the body including the brain and other organs through the circulatory system.

Narrowing and hardening of the artery walls causing buildup of fatty tissues (plaque), cholesterol and other substances, which may restrict blood flow is referred to as atherosclerosis. Having restriction of blood flow develops damage to a patients’ organs and also increases the risk of heart attacks, blood clots, and strokes overtime (WebMD, 2015). It is said to be the most common form of arteriosclerosis that forms small patches and arterial spasms. The plaque also known as atheroma, builds up and may cause the blood clots to burst. Atherosclerosis is considered to be a heart condition, but may also affect arteries in any part of the body and could be prevented and treated (Mayo Clinic, 2015).

CVDs are the number 1 cause of death globally: more people die annually from CVDs than from any other cause. (WHO, 2016). Australians living outside the metropolitan are at greater risk (26%) of suffering Australia’s leading cause of death, CVD. With

As the population ages heart failure is expected to increase exceptionally. About twenty-two percent of men and forty-four percent of women will develop heart failure within six years of having a heart attack. “Thirty years ago patients would have died from their heart attacks!” (Couzens)

The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.

The reason why I choose this topic is very special to me. I was deeply involved with my uncle who suffered from severe heart disease. As no other family member was available to look after him. So, I looked after him and I passed through all that pain with him. Since then, I was very eager to study heart diseases and related topic.
