Did you know that your heart muscle needs oxygen to survive? A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. This happens because coronary arteries that supply the heart muscle with blood flow can slowly become narrow from a buildup of fat, cholesterol and other substances that together are called plaque. This slow process is known as atherosclerosis. When a piece of a plaque in a heart artery breaks, a blood clot forms around the plaque. This clot can block the blood flow through the heart muscle. When the heart muscle is starved of oxygen and nutrients, it is called ischemia. When damage or death of part of the heart muscle occurs as a result of ischemia it is called a heart attack or myocardial infarction (MI). About every 34 seconds, someone the the United States has a myocardial infarction (heart attack).
Did you know that most people recover from a heart attack? The heart muscle begins to heal soon after a heart attack and usually take about 8 weeks. Scar tissue may form in the damaged area, and that scar tissue does not contract or pump as well as healthy heart muscle. That means that the extent of damage of the heart muscle can impact how well the heart pumps blood throughout the body. The degree of loss of function depends on the size and location of the scar tissue. Most heart attack survivors have some degree if coronary artery disease (CAD) and will have to make important lifestyle changes and possibly take medication to prevent a future heart attack and lead a full, productive life.
Did you know that a heart attack may not come with a warning? Atherosclerosis has no symptoms. One reason there may be no warning signs is that sometimes when a coronary artery becomes narrowed, other nearby vessels that also bring blood to the heart sometimes expand to help compensate. the network of expanded vessels is called collateral circulation and helps protect some people from heart attacks by getting the blood to the heart. Collateral circulation can also develop after a heart attack to help the heart muscle recover.
Did you know that all heart attacks cause some damage? When a heart attack occurs, the heart muscle that has lost blood supply begins to suffer injury. The amount of damage to the heart muscle depends on the size of the area supplied by the blocked artery and the time between injury and treatment. Damage to the heart muscle from a heart attack heals by forming scar tissue. It usually take several weeks for your heart muscle to heal. The length of time depends on the extent of your injury and your own rate of healing. The heart is a very tough organ. Even though a part of it may have been severely injured, the rest keeps working. But because your heart has been damages, it may be weaker and can't pump as much blood as usual. However, with proper treatment after a heart attack and lifestyle changes, further damage can be limited or prevented.
Did you know that some heart attacks are sudden and intense where no one doubts what's happening. However, most heart attacks start slowly, with mild pain or discomfort. Often people affected aren't sure what wrong and wait too long before getting help.
Here are signs that can mean are heart attack is happening: Most heart attacks involves discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like an uncomfortable pressure, squeezing, fullness or pain. Symptoms can also include pain or discomfort in one or both arms, the back, new, jaw or stomach. Shortness of breath with or without chest discomfort. Other signs may include breaking out in a cold sweat, nausea or being lightheaded. As with men, women's most common symptom is chest pain or discomfort. But women are somewhat more likely to experience some of the other common symptoms, particularly shortness of breath, nausea/vomiting and back or jaw pain. If you or someone you love experiences any of the above symptoms, please call 911 immediately. Remember- Time is Tissue!!!
