????Leon and Daniel Heart AttacksDefinition:     A heart attack is when there is a blockage of blood flow in the coronary arteries to the heart. The blockage is usually built up of calcium, cholesterol, fat, and other substances, which become plaques. When the plaques are hard, the outside of it cracks, and blood clots then form. Then, blood cannot flow to the heart, the heart cannot get oxygen, and the muscle cells in the heart start to die, leading to a heart attack.Signs/Symptoms:     There are many signs and symptoms of heart attacks. These include cold sweating, chest pain, being lightheaded, short breathing, arm tightness, fatigue, pain that may spread to other parts of your body such as your back or neck, and more.Causes:     There are numerous causes of heart attacks. First is smoking, which lowers the oxygen level present in the blood. Next is obesity, which attributes to higher blood pressure as well as higher cholesterol levels. Finally, coronary artery disease can lead to heart attacks. This is when the arteries leading to your heart are narrower than usual, thus making the process of blood flowing to your heart less successful.Treatment:     There is a thorough process of treatment of heart attacks. After seeking medical attention and going through tests to diagnose the heart attack, such as blood tests and an echocardiography, which is an imaging to look at the heart, treatment can begin. This includes taking drugs that prevent or destroy blood clots, and possibly surgery if needed.Prevention:     There are multiple things you can do to aid in preventing heart attacks for the future. These include monitoring your cholesterol and blood pressure, having check ups with a doctor, and eating foods that are healthy for your heart, such as fruits, veggies, fish, and grains. Other factors that help are exercising, keeping a good weight, and reducing stress.Bibliography: As of January 16th, 2018.Mayo ClinicWebMDMedicinenetCDCMedicalNewsTodayHeart Foundation
