Overview<\/p>\n\t
A heart attack occurs when the blood flow to the heart is blocked. The blockage is most commonly caused by a buildup of cholesterol, fat, and other substances. These form a plaque in the arteries that feed the heart (coronary arteries).<\/p>\n
The plaque breaks away eventually and forms a clot. The interrupted blood flow can destroy or damage part of the heart muscle.<\/p>\n
A heart attack (also called myocardial infarction), can be fatal, but treatment has dramatically improved over the years. It is crucial to call emergency medical services or 911 for help if you think you are having a heart attack.\u00a0If a heart attack is caught early enough it is treatable through procedures and medications such as blood thinners.<\/p>\n\t
Symptoms<\/p>\n\t
Common signs and symptoms of heart attacks include:<\/p>\n
Some heart attacks strike very suddenly, but most people have warning signs and symptoms hours, days, or even weeks in advance. The earliest warning might be recurrent chest pressure or pain that’s triggered by exertion and relieved by rest. Angina is caused by a temporary decrease in blood flow to the heart.<\/p>\n\t
Causes<\/p>\n\t
A heart attack happens when one or more of your coronary arteries get blocked. Over time, a coronary artery can become narrow from the buildup of various substances including cholesterol. This condition, called coronary artery disease, causes a majority of heart attacks.<\/p>\n
While a heart attack is happening, one of these plaques may rupture and spill cholesterol or other substances into the bloodstream. A blood clot forms where the rupture happened. If it’s large enough, the clot can block the blood’s flow through the coronary artery. This starves the heart muscle of nutrients and oxygen.<\/p>\n
You may have a complete or partial blockage. A complete blockage means that you have had an ST elevation myocardial infarction (STEMI). A partial blockage means you have experienced a non-ST elevation myocardial infarction (NSTEMI). Diagnostic steps and treatment can be different depending which you’ve experienced.<\/p>\n
Another cause of heart attacks is a spasm of a coronary artery that shuts down blood flow to part of the heart muscle. If you use tobacco and illicit drugs like cocaine, it can cause a life-threatening spasm.<\/p>\n\t
Diagnosis<\/p>\n\t
Ideally, your doctor will screen you during regular physical exams for risk factors that can lead to heart attacks.<\/p>\n
If you’re in an emergency setting for heart attack symptoms, you’ll be asked about your symptoms and have your blood pressure, temperature, and pulse checked. You’ll be hooked up to a heart monitor and have tests to see if you’re having a heart attack.<\/p>\n
These tests include:<\/p>\n
Treatment<\/p>\n\tHeart attack treatment at a hospital<\/strong> Medications<\/strong><\/p>\n\t\t\t\t\n\t Coumadin is one of the most common blood thinners.<\/strong><\/p>\n\t Medications (including blood thinners) that are given to treat a heart attack include:<\/p>\n In addition to drugs, you could also have one of these procedures to treat your heart attack.<\/p>\n Many hospitals offer programs that might start while you’re in the hospital and continue for a couple of weeks to months after you return home. Cardiac rehabilitation programs usually focus on 4 main areas: lifestyle changes, gradual return to your normal activities, medications, and emotional issues.<\/p>\n It’s very important to fully participate in this program. People who attend cardiac rehab after experiencing a heart attack in general live longer and are less likely to have complications from the heart attack or another heart attack. If cardiac rehab is not recommended during your stay at the hospital, ask your doctor about it.<\/p>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t<\/a>\nHeart Attacks Blog Posts\n\t Overview A heart attack occurs when the blood flow to the heart is blocked.

\nThis catheter has a special balloon that is put into position and then briefly inflated to open a blocked coronary artery. Then a metal mesh stent may be inserted to keep the artery open for the long term, restoring blood flow to the heart. Depending on your condition your stent may be coated with a slow-releasing medication to help keep the artery open.<\/li>\nCardiac rehabilitation<\/strong><\/h4>\n
