Essay about Heart

Another word used to describe a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. A heart attack is the death of a part of the heart caused by the loss of blood supply. The blood supply is usually gone due to a coronary artery being blocked by a blood clot. When a part of a heart artery breaks a blood clot forms around the piece. This blood clot can block the blood flow through the heart muscle. When the heart muscle needs oxygen it is called ischemia. When damage of a part of the heart muscle happens it’s called a heart attack. During a heart attack damage occurs depending on the size of the area blocked by the blood clot as well as the time between the actual heart attack and the treatment. Even though the heart may be hurt, the rest of the organs work with no problems. However, it will not pump as much blood as it used to in order to supply the same amount of blood to all of the parts of the body.

A heart attack occurs when an artery that supplies blood to the heart becomes blocked. The loss of oxygen and nutrients damage the heart's muscle tissue, causing the remaining healthy tissue to pump even harder to keep up.

Cardiovascular disease is a disease that affects the heart and blood vessels which may cause various problems relating to the blood flow to the heart. Many complications arise from cardiovascular disease, which may lead up to other life threatening illnesses such as heart attack or stroke. According to the American Heart Association a heart attack occurs when the blood flow of blood to part of the heart is blocked by a blood clot; if the clot cuts the flow of blood part of the heart muscle begins to die. A stroke occurs when blood vessel that supplies the brain gets blocked from a blood clot and when this occurs sometimes the blood supply to part of the brain shuts off and brain cells die. Several things can overall lead to cardiovascular

Heart Disease mainly consists of coronary artery disease, congestive failure and disease, cardiac arrest, high blood pressure, arrhythmia, and strokes (Centers for Diseases Control and Prevention) The most occurring condition is

Decreased blood flow to the heart muscle can cause an ischemic episode that often presents with chest pain and damages the heart.1

Coronary Heart Disease Coronary heart disease occurs when the coronary arteries become partially blocked from, cholesterol and fat, circulating in the blood. This causes a build up inside the walls of the arteries. This only occurs if the levels of fat and cholesterol are extremely high in the blood that there is a greater chance that it will be deposited onto the artery walls. If the arteries become completely blocked, the patient will have a myocardial infarction, commonly known as a heart attack. A heart attack can cause permanent damage to the heart muscle, and can sometimes be fatal if immediate treatment is not given.

Perhaps the most deadly of all the heart’s complications is a heart attack. A heart attack is the leading killer in men and women in the United States, with an estimate 1 million heart attacks alone in the United States (NHLBI). A heart attack occurs when the heart is unable to obtain oxygen, due to a section of heart muscle becoming blocked and preventing oxygen-rich blood to flow properly. The leading cause of heart attacks is coronary heart disease, also known as coronary artery disease. Coronary heart disease is a result of plague, a waxy like substance, building up inside the coronary arteries, the arteries that are responsible for providing blood to the heart (NHLBI). Overtime, the built up plaque can rupture inside of an artery causing a blood clot to form, which prevents blood from reaching heart muscles. Portions of heart muscle once fed by this now blocked artery begin to die if blockage is not treated in time.

This blood clot can obstruct the blood flow via the heart muscular tissue. When the heart muscle is starved for oxygen and nutrients, it is called ischemia. When harm or fatality of part of the heart muscle takes place as a result of ischemia, it is called a cardiac arrest or coronary infarction (MI). Concerning every 34 secs, somebody in the United States has a heart attack (cardiovascular disease).

This is also called ischemia. It may be chronic, caused by narrowing of the coronary artery and limitation of the blood supply to part of the muscle. Or it can be acute, resulting from a sudden plaque that ruptures (American Heart Association)”.

Coronary artery disease affects all of the arteries that supply blood to your heart. Arteries are narrowed by coronary artery disease and don't allow blood to flow freely through your arteries. When blood can't flow freely to your heart, you can experience chest pain, a heart attack or irregular heart rhythms called arrhythmias.

Heart disease is a chronic, progressive medical condition that affects cardiovascular, respiratory, and nervous systems. The heart is not able to pump adequate amount of blood to fuel the body properly. The heart is not able to keep up with its workload. There are several different kinds of heart failure. Among them, one is left-sided heart failure, in which the left side of the heart works harder to pump blood. The pumping action moves oxygen-rich blood from the lungs to the left atrium, left ventricle, and eventually to the other parts of the body. The left ventricle supplies as the source of pumping power, so it is larger and essential for normal function to be maintained. Two types of left-sided heart failure are systolic failure and

Disorder, which underlines CHD, is called atherosclerosis, process that involves inflammation of the lining of blood vessels leading to progressive accumulation of macrophages, lipid, T lymphocytes, platelets and smooth muscle cells in the walls of the coronary arteries. As a result, coronary arteries narrow so that blood supply to the working heart muscle can decrease. Later, plaque, which is made of fatty cells (cholesterol), forms on vessels that lead to the development of clumps of cells and other material called thrombi. Atherosclerosis generally starting early in life and progressing till people get older. Studies found that atherosclerosis can start developing between 10 and 14 years old (Hong, 2010). However, more people are affected by atherosclerosis in their 20s and 30s (Swiech, 2013). Usually the disease occurs at the stage when the coronary arteries become blocked, partly or completely. Therefore myocardium muscle becomes ischaemic as it is not supplied with blood anymore. At this point person can experience pain in the chest, which is called angina, heart attack or death. Unfortunately, about 47% of cardiac deaths are sudden and happen within 2

Meet Tank 17, a 93-year-old male whose cause of death was an acute myocardial infarction and congestive heart failure. But what exactly is a myocardial infarction and congestive heart failure? To the non-medical community, an acute myocardial infarction is better known as a heart attack, which is caused by blocked vessels in the heart. According to Dr. Gilberto Cabrera, MD and Jennifer Kornusky, RN, MS, an acute myocardial infarction is due to cardiac ischemia (decreased oxygen and blood flow) which occurs when the arteries are narrowed or weakened.1 Congestive heart failure occurs when the heart’s pumping power is weaker than normal. During heart failure, the heart cannot pump enough blood throughout the whole body, causing the body to become “congested” via fluid build up in the “arms, legs, ankles, feet, lungs, or other organs.”3 Congestive heart failure can occur in either the left or right atria. In order to distinguish between diseases with similar symptoms, healthcare professionals have developed differential diagnoses. A differential diagnosis is the process differentiating between many different possibilities and winnowing them down to one probable illness or disease based on clinical findings. A patient may present with multiple symptoms for an illness that is not yet known, or multiple causes for a symptom that is not yet known. The defining differential diagnosis for acute myocardial infarction is acute chest pain. While assessing the patient, a focused

Another type of cardiovascular disease is a myocardial infarction, or a heart attack. This is when the heart does not get enough blood flow and the heart is not getting enough oxygen and the part of the heart that is not getting any blood and oxygen starts to die and the heart attack occurs. The heart may not be getting enough oxygen because the coronary arteries that deliver blood to the heart could be narrowing due to plaque buildup in the artery, or there could be a blood clot not allowing that blood to get to the heart.

From the very first time the heart starts pounding until the time of death, it may beat more than 3.5 billion times. The center of the circulatory system is the heart. The average heart beats 100,000 times each day, pushing around 2,000 gallons of blood throughout your body. With a life span of 70-90, the heart will beat two to three billion times and circulate 50-65 million gallons of blood.
