Coronary Heart Disease Research Paper

Coronary artery disease (CAD), also known as coronary heart disease, is the leading cause of mortality in both men and women in the United States today. It has been reported by the Centers for Disease Control and Prevention that CAD accounted for nearly 616,000 deaths in 2011 and was responsible for 1 in 4 deaths in the U.S. in the same year. 1 Coronary artery disease is a progressive disease where the major arterial vessels supplying the heart become occluded and sclerotic due to the buildup of plaque in the inner walls of the artery through a process called atherosclerosis. 2 CAD eventually leads to heart failure and a myocardial infarction (MI).

CHD is the most common type of cardiovascular disease [2] and was the leading cause of death globally between 2000 and 2012 [3] – accounting for 14.6% of all deaths in Australia in 2011 (21,513 persons) and 7.8% of all disability-adjusted life years (DALYs) in Australasia in 2010 (471,550 DALYs) [4]. In 2011-12, CHD was estimated to affect 585,900 Australians, with the condition being more common in men (3.3%) than women (2.0%) and among those aged 70 and over (15% compared with 2.2% for those aged 25-69) [4]. In 2008-09 more than $2 billion was spent on CHD treatment and expenses – more than any other disease in Australia [5].

Throughout the United States there are many illnesses and diseases, though there is only one disease that kills about six hundred ten thousand people yearly, heart disease. Six hundred ten thousand people yearly is the reason why heart disease is the leading cause of death in the United States, that is one in every four deaths. Seems like a serious and scary situation correct; if you knew about this information would you have done something sooner or begin doing something? An individual can do many changes in their lifestyle to prevent heart disease from developing in their body and the best way to make those changes is to act now.

You lounge on your couch and watch your favorite sitcom on the television. An ice cream commercial comes up, and all of a sudden you feel like having some ice cream too. You reach for a spoonful of ice cream in your freezer, but find yourself finishing half the tub in the next moment. Coronary heart disease has become a worldwide epidemic; with its major causative factors including diet and lifestyle. A statistic provided by the Centers for Disease Control and Prevention (CDC) stated that in the United States, about 610,000 people die of heart disease annually– that’s 1 in every 4 deaths. More than half that amount of death is caused by coronary heart disease.

The leading number one killer of the United States population is coronary heart disease. Coronary heart disease happens when not enough blood flow reaches the heart, which possibly will cause a heart attack. The main people who are at risk from this disease are the smokers, people who are diabetic, have high blood pressure, high cholesterol and genetic risk factors. The chances of getting heart disease also increase the older one gets.

Heart disease can be genetic. If a person has family history of cardiac disease then the probability or risk of suffering from heart problem is increased in that person. Along with this, heart disease can occur if a person has unhealthy life style practices. Unhealthy practices that puts a person to increased risk for heart disease involve smoking, high fat and high sugar diet, alcohol consumption and sedentary life style. Many heart related conditions and illnesses can be easily prevented by following healthy life style. By having a healthier lifestyle, a person can control risk factors (conditions that can increase the risk of having heart disease) that includes obesity, high blood pressure, high cholesterol, diabetes and much more. Healthy

Coronary Artery Disease (CAD) is a type of heart disease where plaque accumulates in the coronary arteries, which provide blood to the heart. The plaque is made of cholesterol deposits, and when it builds up in the arteries, it causes the arteries to slowly narrow (atherosclerosis). A very common symptom of CAD is angina, which is caused by the buildup of plaque. Angina is chest pain that is caused by reduced flow of oxygen rich blood to the heart. This makes the heart muscle weak, and can lead to another symptom of CAD, arrhythmia. Arrhythmia is an irregular heartbeat. However, sometimes these symptoms don’t show up at all. The first indication of CAD in some people is a heart attack. A heart attack is when a plaque buildup blocks an artery completely and thus, stops blood flow to the heart.

Cholesterol is a waxy, fat-like substance that is found in the cells of our body. Cholesterol is necessary to make hormones, vitamin D and certain substances that helps to digest food. In our body, cholesterol travels through bloodstream in packages known as ‘lipoproteins’. Lipoproteins are composed of fat (lipid) on the inside and proteins on the outside. However, high blood cholesterol is harmful for us. High blood cholesterol is responsible for coronary heart disease (coronary artery disease) which affects the heart. Low-density lipoproteins (LDL) are responsible for heart disease while the high-density lipoproteins (HDL) does not cause heart disease. Coronary heart disease is a condition when plaque builds up in the arteries that supplies oxygen to the heart. Plaque is composed of cholesterol, fat, calcium and few other

Heart disease is a massive worldwide killer. In Australia alone coronary heart disease affects more than 3.2% of the nation (Craft, Gordon, & Tiziani, 2011, p. 621). Statistics show that 7.5% of Australians aged between 55 and 64 will be affected by acute coronary syndrome at some stage in their lives and an astounding 25% of those aged over 75 also suffer. Coronary heart disease is accountable for on average 20% of deaths in Australia and New Zealand (Craft, Gordon, & Tiziani, 2011, p. 621). Acute coronary syndrome leads to approximately ninety thousands hospitalisations yearly (AstraZeneca Australia, 2014).

As shown in Figure 2 (Page 2), the Australian Institute of Health and Welfare (AIHW) observed a 73% decrease in mortality caused by CHD, between 1968 and 2011 [2]. More specifically, the decline in the mortality rate occurred in the late 1960s, where these changes were most evidence in males and females aged 55-64 and 65-74 years respectively [21]. As shown in Figure 3 and 4 (Page 2), the mortality rate in men aged 35-44 and 45-54 years declined at a decreasing rate, in contrast to older men where the mortality rate had increased [21]. In women however, the rate of overall decline had only been hindered in the 45-54 age category, as opposed to increasing in older age groups [21]. Thus, over the past century, mortality rates have generally declined [2]. Although, this rate of decline is gradually improving in older populations and deteriorating in younger

Coronary Heart disease is a disease in which a waxy substance called plaque builds up inside the coronary arteries.The arteries supply oxygen rich blood to your heart muscle.What cause (CAD) is smoking,Fats and cholesterol in the blood,High blood pressure,insulin resistance or diabetes,Blood vessel inflammation.How does the disease get treated, it get treated by taking medications,sugical procedures,regular check ups.

Coronary artery disease is the most ordinary type of heart disease which is leading to death in worldwide 405,309 people died from this disease in 2008. Coronary artery disease happens when the fatty substance deposit inside arterial wall, it blocks the blood flow inside coronary artery, reducing oxygen and cause damage to heart muscle.

In my way of thinking, Cardiovascular Disease is one of the easiest or better yet one of the only diseases that you can prevent. You can prevent it by basically having a healthier lifestyle. By that I mean eating healthier, exercising, and not smoking. But I am mainly gonna focus on eating healthier since that it is most important. Eating healthier is huge because if you eat a lot you’ll gain weight which will cause your respiratory system to work harder. Also if you eat healthy you’ll get sufficient vitamins and protein needed to be healthy. Also this ties into exercising because if you have a healthy diet, you might as well exercise to get even more healthy. Also I read that if you eat fruits and vegetables it will make you eat less high-

Coronary heart disease occurs due to the built up of plaque within coronary arteries. Coronary arteries play an important role in supply the oxygenated blood to cardiac muscles in the heart. The oxygenated blood supplies the cardiac muscles with oxygen and nutrients, so that the muscles are able to continue contract and relax and prevent them from tetanizing. Plaque is a waxy substance that blocks the coronary arteries, thus reducing rate of blood flow to heart muscle. This condition may lead to ineffective functioning of heart due to lack of nutrients and oxygen. To make the matter worse, accumulated plaque becomes atherosclerosis where this substance grows and eventually cause damaging effects which is

Cardiovascular disease (CVD) is a class of disorders that involves the heart and blood vessels. A major contributor to CVD is atherosclerosis. The complications of atherosclerosis are the most common cause of death in Western countries. Rupture of atherosclerotic plaques lead to dangerous clinical complications such as myocardial infarction and stroke. Epidemiological studies identified many lifestyle factors that increase the risk of developing atherosclerosis. Mostly older or middle-aged adults are affected by the disease, although the process already starts in early life. The onset of atherosclerosis mostly starts with endothelial dysfunction. Different cellular elements of the arterial wall are involved, such as monocytes, macrophages,
