Myocardial Infarction

Myocardial Infarction also known as “heart attack”, is when a damaged muscle or artery is blocked preventing the blood to flow through. Because of fast food places such as McDonalds, Burger King, Wendy’s and etc… Most Americans prefer eating outside than having a healthy home cooked meal. Many people do not realize the amount of fatty and oily substances that are in the meals that are being cooked. Heart attack is a leading killer in most men and women in the United States .

The heart is made up of four chambers, two atriums and two ventricles. The right side of the heart pumps blood into the lungs and left side pumps blood into the organs and tissues of the body. The right ventricles carry deoxygenated blood to the lungs and the oxygenated blood is carried by the pulmonary veins to the whole body. Blood flows through the coronary arteries also but if one of the arteries gets clogged, blood will not be able to pass through smoothly causing it to build up and damaging the heart muscle. This leads to a very serious heart condition known as Myocardial Infarction or in other words “heart attack”. …show more content…
According to the National Heart Lung and Blood Institute, “Heart attacks occur most often as a result of a condition called coronary artery disease” (CAD). During a heart attack, if the coronary artery isn’t treated right away, the heart muscle begins to die and then gets replaced by scar tissue. Due to this, the heart damage may not be obvious and will cause severe or long-lasting

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    The blood flows through our heart in a series of different steps and factors. Oxygen flows into the heart through the right atrium where at this time the tricuspid valve is closed, allowing the blood to fill the right atrium. Next, the muscle walls of the right atrium contract and push the blood through the tricuspid valve into the right ventricle. Once this occurs the right ventricle contracts and pushes the blood through the pulmonic valve into the pulmonary artery. The oxygen rich blood is then returned from the lungs to the left sides of the heart and into the left atrium. The contract of the muscle of the left atrium pushes the blood out into the left ventricle. Finally once the left ventricle fills with blood the muscle walls contract pushing blood into the aorta and throughout the body (Thibodeau, 2008).…

    Blood enters the heart through the Superior Vena Cava which is the large vein at the top of the heart, and the Inferior Vena Cava, which is the large vein at the bottom of the heart. Blood flows into the right atrium, passes through the tricuspid valve, and makes its way into the right ventricle. It then moves through the pulmonic valve, into the pulmonary artery to the lungs.” After picking up oxygen in the lungs, the blood moves out of the lungs into the pulmonary vein, into the left atrium, through the mitral valve, and into the left ventricle that pushes blood to the body through the aortic valve. Once blood leaves the heart it is in the aorta where it flows to various parts of the body” (Whitlock, J. 2017).…

    Coronary Atherosclerosis

    CAD is thought to begin with damage or injury to the intimal layer of coronary artery, sometimes as early as childhood. The damage may be caused by various factors, including: smoking, hypertension, hypercholestromia, diabetes or insulin resistance, radiation therapy to the chest, as used for certain types of cancer, and sedentary lifestyle. Once the intimal layer of coronary artery is damaged, fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of these plaques breaks or ruptures, platelets will clump at the site to try to repair the artery. This clump can block the artery, leading to a heart attack. Recent research has…

    Coronary Heart Disease Research Paper

    Coronary heart disease or CHD is a narrowing of the small blood vassals that supply the heart with blood and oxygen. The disease develops when a combination of fatty material, calcium, and scar tissue or plaque, builds up in the arteries that supply the heart with blood. This slows the blood flow and causes chest pain. Men in their 40s have a higher risk of CHD than women. But, as women get older, their risk increases so that it is almost equal to a man's risk.…

    Coronary heart disease happen when the plaques, a waxy substances, build up inside the coronary arteries causing it to get narrower. Coronary arteries are the arteries that supply the patient's heart muscle with the oxygen-rich blood. The condition of the plaques building up is called Atherosclerosis and it occurs over many years. The plaques can harden and break open narrowing the coronary arteries over time. When the plaques harden the flow of the oxygen-rich blood is to going to be reduced. Sometimes, the plaques rupture causing a blood clot to form on its surface. Large blood clots can easily and completely block the flow of blood causing the heart to stop. (2)…

    The Public Needs to Know

    Americans continue to become more and more overweight. They continue to fill themselves with empty carbohydrates and fatty foods that are full of sodium and cholesterol. The fast food industry is part of the blame, along with the public’s unhealthy food choices. The fast food industry grew out of the need for a quick fix for hunger. It has become quite cheap and is easily accessible. However, it is almost always not a healthy choice. Americans die of heart disease every day and “about 600,000 people die of heart disease in the United States every year” (cdc.gov). This amounts to about “1 in every 4 deaths” (cdc.gov). Heart disease continues to be the leading cause of death for both men and women. The affects of heart disease continue to affect the community, as “every year about 715,000 Americans have a heart attack” (cdc.gov).…

    The Risk Factors of Heart Attack

    Heart attack is the death of a segment of heart muscle caused by the loss of blood supply. The blood supply is usually lost because a coronary artery, one that supplies blood to the heart muscle, has a blood clot, a blockage also known as coronary thrombosis or coronary disease. ("What Is A Heart Attack? What Causes A Heart Attack?" 2013) Heart disease is the number one killer of both men and women in America with approximately 460,000 related deaths due to a sudden and unforeseen heart attack. Of those who die, almost half suffer an attack so suddenly that they do not have time to call an ambulance or get to a hospital in time. (Fleet, 2013, p. 1) Its symptoms will actually vary from person to person; in fact some people will go from having no symptoms to just a few ones that they will be surprised to learn that they have already gotten a heart attack. The heart attacks without any symptoms are called silent heart attacks. ("What Are The Symptoms Of A Heart Attack?" 2013) Most heart attacks usually involve some kind of discomfort in the chest; it usually last a few minutes, goes away and then comes back. Sometimes it feels like heartburn or indigestion. Other people will feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach. Shortness of breath while resting or doing a little bit of physical activity can also be encountered. Breaking out in a cold sweat, women feeling unusually tired for no apparent reasons, feeling sick to the stomach and vomiting, feeling lightheaded and dizzy are also other common symptoms associated with heart attack.

    Heart Attcks

    Each Year 1.1 Million people in the United States have heart attacks and almost half of them die. Even though heart attacks isn't the end of a person's life, people can still live an active, productive life after a heart attack, because people can live healthier lives and people can go about doing things like before. This disease will take you by surprise all of a sudden. It may be surprising that while many women believe breast cancer is most threatening to them, it is a fact that they are eight times more likely to die of a heart attack. There are many reasons people have heart attacks like smoking, eating an unbalanced diet, and living a sedentary lifestyle. Heart attacks can also be inherited genetically. Heart attacks happen as a result of coronary heart disease, also called coronary artery disease. Coronary heart disease is a condition in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen rich blood to your heart. When this plaque builds up in the arteries, atherosclerosis then happens. Coronary Artery Disease which often leads to a heart attack is by far the leading cause of death of both men and women. Other Names for a heart attack include the name Myocardial Infarction, Coronary Thrombosis and Coronary Occlusion. A Heart attack occurs when blood supply to part of the heart muscle itself is severely reduced or stopped. Plaque build up is one way of causing a heart attack, deposits of fat like substance this is when plaque blocks in artery and eventually bursting, tearing, and even rupturing where in which a blood clot forms and blocks the artery. This is and when a heart attack takes place. But as well there is also soft and vulnerable plaque in which doctors used to believe that the reason for heart attacks and strokes were the buildup of fatty plaque within an artery leading to the heart or the brain. Researchers are now founding out that people who have heart attacks do not have arteries severely…
