What is a heart attack? Myocardial Infarction (MI) commonly known as heart attack occur when blood supply is interrupted, causing damage or death of the heart cells. A heart attack can be caused from many reasons. You are able to tell when someone is having a heart attack because of the many symptoms.
A heart attack occurs when a artery that supplies blood to the heart collapses and stops the blood flow to the heart. A heart attack is very deadly and can instantly kill you if more than one artery collapse at one or you have had many in the past. “About 600,000 people die from a heart attack each year, 1-in-4 people. Every year about 720,000 have a heart attack (Heart Disease, 2014).” The cause of a heart attack is the blockage of an artery, for a artery to become blocked it will have a build up of substances like cholesterol.
“Some common symptoms of a heart attack are: Pressure, tightness, pain or a squeezing or aching sensation in your chest or arms that may spread to your neck, jaw or back, Nausea, indigestion, heartburn or abdominal pain, shortness of breath, cold ...
The term acute myocardial infarction is used when talking about myocardial necrosis in a setting consistent with myocardial ischemia (Steg, et al., 2012). Acute myocardial infarctions are the major cause of disability and death worldwide. Myocardial infarctions can be one of the first signs of acute coronary syndrome and they can also occur repeatedly in patients that have an ongoing coronary artery disease (Thygesen, et al., 2012).
In a conclusion, although cardiovascular disease remains the major concern to many citizens, the survival rate is still high for those who admitted to hospital as the improvement in medical care and emergency treatment plan. However, one should instantly seek for medical aid when developing symptoms of myocardial infarction such as chest pain, shortness of breath and nausea. Precautions are always better than cure, one should maintain a healthy diet, exercise regularly and quit smoking in order to avoid the occurring of cardiovascular disease.
A heart attack (myocardial infarction) is the death of heart muscle due to the loss of blood supply. Usually, the loss of blood supply is caused by a complete blockage of a coronary artery by a blood clot. A coronary artery is an artery that supplies blood to the heart muscle. Death of the heart muscle causes chest pain and electrical instability of the heart muscle tissue. Electrical instability of the heart causes ventricular fibrillation (chaotic electrical disturbance). Orderly transmission of electrical signals in the heart is important for the regular beating (pumping) of the heart. A heart undergoing ventricular fibrillation quivers, and can not pump or deliver oxygenated blood to the brain. Permanent brain damage and death can occur unless oxygenated blood flow is restored within five minutes.
Heart disease describes a range of conditions that affect your heart. Diseases under the heart disease umbrella include blood vessel diseases, heart rhythm problems, and heart defects. The major cause of this is a build-up of fatty plaques in the arteries. Plaque build-up thickens and stiffens the vessel walls, which can inhibit blood flow through the arteries to organs and tissues.
Myocardial infarctions are caused by vascular endothelial disruption most often associated with plaque build-up or atherosclerosis that develops over several years and causes thrombus formation which in turn
Ischemic Heart Disease, also known as Coronary Artery Disease, is a condition that affects the supply of blood to the heart. Coronary artery disease may show no signs of symptoms, or chest pain before you know heart attack. The blood vessels are narrowed or blocked due to the deposition of cholesterol on their walls. This reduces the supply of oxygen and nutrients to the heart muscles, which is essential for proper functioning of the heart. This may eventually result in a portion of the heart being suddenly deprived of its blood supply leading to the death of that area of heart tissue, resulting in a heart attack. The cardiovascular issue has been a big problem for people who
Signs and symptoms come along with any disease, some symptoms may be noticeable but sometimes there's just no symptoms at all. The common symptom for Coronary Heart Disease is chest pain and/or discomfort. This happens when the heart is not getting oxygen and blood. How strong the chest pains are varies from patient to patient. The chest pains my feel like the heart is being squeezed. The pain may be felt below the sternum but also in the neck, arms, stomach, and upper back. The chest pain usually occurs when the patient is doing activities or is in motion but it goes away with rest or a medicine called Nitroglycerin. Other symptoms are sho...
lives. A simple definition of a heart attack is a sudden failure of the heart
Heart attacks are often causes of heart failure. A heart attack occurs when, “a coronary artery becomes blocked suddenly, stopping the flow of blood to the heart muscle.” A heart attack injures the heart muscle, scarring a part of the heart and resulting in a region of the heart unable to function like it typically would. Coronary artery disease is also a cause of heart disease. CAD is a “disease of the arteries that supply blood and oxygen to the heart.” When multiple disease are occurring at once, that can also be a facyor leading to heart
Succinctly speaking, a myocardial infarction is not a disease but rather an event occurring due to the progression of coronary heart disease. 1(p.125) With coronary heart disease, the flow of blood which supplies the heart with oxygen is blocked, reducing the amount of oxygen received by the cardiac muscles and resulting in damage or death of cardiac muscle....
Heart disease, also known as cardiovascular disease, is a disorder that affects the heart. Heart disease is the leading cause of death of most ethnicities in the United States, including African Americans, Hispanics, and Whites. For American Indians or Alaska Natives and Asian or Pacific Islanders, heart disease is the second leading death. Although heart disease is often thought of as a problem for men, more women than men die of heart disease each year.
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.
Heart disease kills over 600,000 men and women in the United States every year. That translates to one out of every five deaths are caused by heart disease. Heart disease has several factors, but they all contribute to difficulty in blood flow from the heart. It is most often caused by an unhealthy lifestyle such as a poor diet, little exercise, being overweight and smoking. People die from heart disease several ways including heart attack or stroke.
There are many symptoms related to heart attacks, the most important one is chest pain. Chest pain can be derived from many other reasons and not necessarily is related to the heart, but the only way to confirm whether or not is relate to the heart is doing the necessary studies. Angina pectoris is a disease that can cause mild to moderate pain, and the pain may spread to the arms and the jaw, like the symptoms of a heart attack. The pain is inconsistent and come and goes, as Dr. Maestri said, “your body is telling you: take care because you may have a heart attack.”
...heart attack. Heart Disease can refer to an assortment of diseases affecting the heart. A heart attack happens when heart muscle is destroyed or hurt due to not getting enough oxygenated blood to maintain life. Different examples of Heart Disease include Cardiomyopathy, Cardiovascular Disease, Hypertension, and Ischemic Hear Disease.
