Myocardial Infarction is the medical term for heart attack, a heart attack happens when the flow of oxygen-rich blood to a section of the heart muscle suddenly becomes blocked and the heart can no longer receive any oxygen. If the blood flow isn’t restored rapidly, the section of the heart muscle will begin to die. There is some good news for people who have heart attacks, there are excellent treatments that are available, theses treatments can help save lives and prevent further damage to the patient. The sooner the treatment is given the faster the response time.
What is a Myocardial Infarction? Myocardial Infarction, also known as a heart attack, occurs when there is a blockage in one of the coronary arteries. The heart is a muscle that needs oxygenated blood and nutrients to survive. When a blockage occurs in the arteries, oxygen and nutrients are cut off from the heart for an extensive time. The blocked portion of tissue in heart dies. Blockages can occur due to several factors. Coronary artery disease is the most prevalent cause. Coronary artery disease or atherosclerosis is due to plaque buildup and narrowing in the artery walls. These plaques are made from cholesterol and waste products. This buildup on artery walls can restrict blood flow; a process that can take
Coronary Artery Disease Heart Disease Heart disease can take many forms. The form of heart disease I am focusing on is coronary disease. Different arteries supply different areas of the heart with oxygenated blood. If one or more of these arteries become narrowed or clogged as a result of coronary artery disease, or atherscelorosis the artery cannot fully supply the part of the heart it is responsible for. The heart is an effective pump only when good blood supply is maintained to all heart muscles.
Atherosclerosis develops when plaque builds up in the walls of the arteries, which makes it harder for the blood to flow through. If a clot blood forms, it can cause the person to have a heart attack or stroke because the heart is blocked by this blood clot. If the blood clot cuts off the flow of blood to the heart, the part of the heart muscle supplied by the artery begins to die. Most people overcome the first heart attack and return to normal for many years of being active in their daily lives (Mayo). But, their daily routine may change because the doctor may decide to put them on medicine along with a diet and workout plan depending on how much the attack damage the person. “In a healthy person with a normal, healthy heart, it 's unlikely for a fatal arrhythmia to develop without some outside trigger, such as an electrical shock or the use of illegal drugs. That 's primarily because a healthy person 's heart is free from any abnormal conditions that cause an arrhythmia, such as an a...
Our heart is a muscle. Which means, our heart needs oxygen. A heart attack takes place when the blood flow that brings oxygen to the heart is stopped. This goes on because coronary arteries that helps supply
Every 34 seconds someone has a heart attack in the United States. Heart Attacks, which are also referred to as myocardial infarctions, have become a leading health issue in America. According to the American Heart Association, about 920,000 Americans have a heart attack each year, and about 452,000 of those result in death. The problem strikes when blood flow to a part of the heart is blocked for a long period of time and causes the heart to stop pumping. If the heart is not pumping, it can cause a heart muscle to become severely damaged or die. Heart attacks can happen for a number of reasons, but the two main concerns are plaque and smoking.
Heart attacks are known in the medical community as myocardial infractions. Some of the most common symptoms or warning from a heart attack may include chest discomfort due to an uncomfortable pressure, fullness, squeezing or pain in the center of the chest (angina). Another symptom is the discomfort in other areas of the upper body because of pain or discomfort in one or both arms, the back, neck, jaw or stomach. The next one is shortness of breath with or without chest discomfort. Lastly, there are other signs such as nausea, dizziness, lightheadedness or cold sweat. There are some cases when these symptoms are not present or the person is considered to be healthy and a heart attack can strike without any warning sings. (Causes,
In cases of a myocardial infarction, a coronary artery or even one of its smaller branches becomes blocked. This causes the part of the heart that is supplied by that artery to lose its blood supply. In retrospect, the affected part loses it oxygen supply and undergoes necrosis. Therefore, when a part if the heart is said to be infarcted, it means that that part of the heart muscle is damaged. The area affected depends on the size of the coronary artery that has been blocked. If a larger coronary artery is blocked, then a larger portion of the heart muscle is affected. On the contrary, if a smaller sized artery is affected then a smaller portion of the
In cardiomyopathy, the heart muscle can become enlarge, thick, or rigid, and in some rare incidents the muscle tissue can become replaced with scar tissue. As the condition worsens, the heart becomes weaker and less able to pump blood throughout the body. The heart will also become unable to maintain a normal electrical rhythm. Results from cardiomyopathy can lead to heart failure or irregular heartbeats called arrthymias (American Heart Association, 2016).
