Created with Fabric.js 1.4.5 Heart Attacks Aka: Myocardial Infarction Not: Cardiac Arrests! The circulatory system is a system that consists of your heart, veins, arteries, capillaries, and blood. Its normal job is to deliver oxygen and other nutrients to its targeted cells in the body, and get rid of any waste that the cells need to get rid of, such as carbon dioxide. ---------------------------- Affects: The Circulatory System --------------------------------- ---------------------------------- Clinical Description -------------------------------------- Most heart attacks start slowly, and are accompanied by discomfort in the upper body, cold sweats, nausea, or lightheadedness. Many people feel as though their heart is skipping a beat or beating too fast. You can tell if you're having aheart attack by watching for these symptoms: chest discomfort, shortness of breath, discomfort in the upper back, arms, neck, or stomach, cold sweats, nausea, or lightheadedness. A heart attack occurs when the blood flowing to the heart and bringing it oxygen is cut off. This happens when plaque builds up in the coronary arteries, causing the path the blood flows through to become much narrower. The heart is then in severe need for oxygen and nutrients, which become hard or impossible for it to access. The circulatory system begins when blood is pumped out of the heart through the aorta, full of oxygen. It then travels through veins to the part of the body it needs to reach. Oxygen and nutrients diffuse into the cells while carbon dioxide and any wastes diffuse into the blood cells, which are taken back to the heart through arteries. Next, the blood is pumped through the pulmonary arteries to the lungs where the blood cells will release carbon dioxide and receive oxygen. The blood then flows back to the heart, and the circle starts again. Detection ------------------- The best you can do to prevent a heart attack before it happens is taking medication, maintaining a healthy lifestyle, not smoking, managing stress, and exercising. Treatment ---------------------------------------------------- A heart attack will occur once and maybe happen multiple times in a persons life, but it isnt an ongoing disease. There is no cure for this disorder, just maintain a healthy lifestyle and it will be less likely to happen to you. Also, while a heart attack is occurring, the most important thing to do is relieve any blood clotting to clear a passageway for the blood to reach the heart. By Eli Melmon ----------------------------------- Prognosis and Outlook After a heart attack, the victim can be more vulnerable to other heart diseases, such as cardiac arrest, and should take many steps to prevent anything life-threatening to happen. After a heart attack, or to prevent a heart attack, one should exercise daily, quit smoking, reduce stress, limit alcohol, aim for a healthy weight, and eat well. ------------------ Treatment After a heart attack, a victim might take medication, change their everyday lifestyle, get surgery, or a attend rehab.
