Treatment of a Heart Attack

Treatment for a heart attack Understandably, treatment for those diagnosed with heart attack can be complex. But this section on heart attack treatments will help you talk with your doctors and healthcare providers. As you learn about your treatment plan, don’t be afraid to ask questions. Be sure to voice any concerns you may have. Common heart attack types and treatments The type of heart attack (also called myocardial infarction, or MI) you experienced determines the treatments that your medical team will recommend. A heart attack occurs when a blockage in one or more coronary arteries reduces or stops blood flow to the heart, which starves part of the heart muscle of oxygen. The blockage might be complete or partial: • A complete blockage of a coronary artery means you suffered a “STEMI” heart attack or ST-elevation myocardial infarction. • A partial blockage is an “NSTEMI” heart attack or a non-ST-elevation myocardial infarction Treatments differ for a STEMI versus NSTEMI heart attack, although there can be some overlap. Hospitals commonly use techniques to restore blood flow to part of the heart muscle damaged during a heart attack: • You might receive clot-dissolving drugs (thrombolysis), balloon angioplasty (PCI), surgery or a combination of treatments. • About 36 percent of hospitals in the U.S. are equipped to use a procedure called percutaneous coronary intervention (PCI), a mechanical means of treating heart attack. At a hospital equipped to administer PCI, you ...

Acute Myocardial Infarction (MI)

Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and/or diaphoresis. Diagnosis is by electrocardiography (ECG) and the presence or absence of serologic markers. Treatment is antiplatelet drugs, anticoagulants, nitrates, beta-blockers, statins, and reperfusion therapy. For ST-segment-elevation myocardial infarction, emergency reperfusion is via fibrinolytic drugs, percutaneous intervention, or, occasionally, coronary artery bypass graft surgery. For non-ST-segment-elevation myocardial infarction, reperfusion is via percutaneous intervention or coronary artery bypass graft surgery. In the US, about 1.0 million myocardial infarctions occur annually. Myocardial infarction (MI) results in death for 300,000 to 400,000 people (see also Cardiac Arrest Cardiac arrest is the cessation of cardiac mechanical activity resulting in the absence of circulating blood flow.

Pulmonary Infarction: Causes, Treatment, and Recovery

Depending on its size and location, the symptoms of a pulmonary infarction can vary from person to person, from being quite mild to extremely severe. However, whatever its symptoms, when a pulmonary infarction occurs it always means there is a serious underlying medical problem, and aggressive evaluation and treatment is needed. Whatever the cause, very large pulmonary infarctions are relatively uncommon, because lung tissue has three potential sources for oxygen: the pulmonary artery, the bronchial artery (arteries that supply the bronchial tree), and the alveoli themselves (the air sacs within the lungs). This means that life-threatening pulmonary infarctions are most commonly seen in people who have significant underlying medical problems, such as In a person who is diagnosed (or suspected of having) a pulmonary embolus, a doctor will also be suspicious of a pulmonary infarction if the patient is experiencing hemoptysis or chest pain, or if the physical exam shows evidence of a very large embolus (in particular, if tachycardia, rapid breathing, or excessive sweating are present). In addition, a pulmonary infarction that affects the pleural lining of the lungs may produce a distinctive “pleural rubbing” sound that is audible with a stethoscope, a sound that resembles rubbing two pieces of leather together. Supportive care includes maintaining adequate blood oxygenation by administering oxygen and controlling pain to make breathing more comfortable. If adequate blood oxyg...

Infarction

A small stroke deep within the brain (as in the internal capsule, basal ganglia, thalamus, or pons) caused by damage to or a blockage of a tiny penetrating artery. Lacunar infarctions are associated with a kind of vascular damage caused by chronic high blood pressure called lipohyalinosis. They may be asymptomatic, showing up only on brain imaging, or may produce pure motor, pure sensory, ataxic, or mixed motor and sensory symptoms. Synonym: malignant cerebral artery infarction The loss of living heart muscle as a result of coronary artery occlusion. MI or its related syndromes (acute coronary syndrome or unstable angina) usually occurs when an atheromatous plaque in a coronary artery ruptures, and the resulting clot obstructs the injured blood vessel. Perfusion of the muscular tissue that lies downstream from the blocked artery is lost. If blood flow is not restored within a few hours, the heart muscle dies. Synonym: cardiac infarction Acute MI affects 1.1 million people each year, and approx. 350,000 of them die. The probability of dying from MI is related to the patient's underlying health, whether arrhythmias such as ventricular fibrillation or ventricular tachycardia occur, and how rapidly the patient seeks medical attention and receives appropriate therapies (such as thrombolytic drugs, angioplasty, antiplatelet drugs, beta blockers, and intensive electrocardiographic monitoring). See: illustration; Etiology Proven risk factors for MI are tobacco use, diabetes mellit...

Infarct

Medical Dictionary for the Health Professions and Nursing © Farlex 2012 infarct A volume of dead tissue lying within living tissue, the death being caused by local loss of blood supply. Infarcted tissue swells and becomes firm, and blood vessels around an infarct widen. Plasma and blood may pass into the infarct, increasing the swelling. Later the infarct becomes pale and shrinks and soon it is replaced by fibrous tissue and is converted into a scar which is usually at least as strong as the original tissue. Function is, of course, lost. Another reason for a lack of association between stroke patterns and AF in both the Find-AF and the CRYSTAL-AF study could be the inclusion of patients with small strokes and low National Institutes of Health Stroke Scale (NIHSS) (median NIHSS in the CRYSTAL-AF was <2 and in our study 3), as there is a known association between large infarct volumes and high NIHSS in patients with cardioembolic strokes caused by AF [17].

STEMI Heart Attacks and Why They Are So Dangerous

• A fatty substance called • This stress triggers a tear in the artery, which • This causes a complete blockage in the artery. • When blocked, the part of the heart muscle serviced by that artery will quickly suffer from a lack of oxygen, also called ischemia. • Some of the heart muscle will begin to die resulting in a Anterior STEMI An anterior STEMI refers to an attack resulting from an infarction in the left anterior descending (LAD) artery. The LAD supplies more oxygen to the heart than other arteries, pumping blood into the anterior (front) side of your heart. Thus, this type of blockage is associated with the greatest risk of heart failure and fatality. Inferior STEMI attacks are less severe than anterior ones because the RCA and LCX are smaller than the LAD. Thus, infarctions in these arteries don't disrupt the blood flow as much. While 40% to 50% of myocardial infarctions are related to inferior infarctions, people with these conditions tend to have low rates of hospitalization and risk of death compared to anterior STEMI patients. • Pascual I, Hernandez-Vaquero D, Almendarez M, et al.

Heart Attack: Symptoms and Treatment

A heart attack (medically known as a myocardial infarction) is a deadly medical emergency where your heart muscle begins to die because it isn’t getting enough blood flow. A blockage in the arteries that supply blood to your heart usually causes this. If a healthcare provider doesn’t restore blood flow quickly, a heart attack can cause permanent heart damage and death. Overview A blocked coronary artery prevents blood from reaching your heart muscle and causes a heart attack. What is a heart attack? A myocardial infarction (commonly called a heart attack) is an extremely dangerous condition that happens because of a lack of blood flow to your heart muscle. The lack of blood flow can occur because of many different factors but is usually related to a blockage in one or more of your heart’s arteries. Without blood flow, the affected heart muscle will begin to die. If blood flow isn’t restored quickly, a heart attack can cause permanent heart damage and death. A heart attack is a life-threatening emergency. If you suspect you or someone you’re with is having a heart attack, call 911 (or your local emergency services phone number). Time is critical in treating a heart attack, and a delay of even a few minutes can result in permanent heart damage or death. What does a heart attack feel like? When a heart attack happens, blood flow to a part of your heart stops or is far below normal, which causes injury or death to that part of your heart muscle. When a part of your heart can’t...
