What does acute MI mean in medical terms?
What does acute MI mean in medical terms?
Overview. A heart attack or acute myocardial infarction (MI) occurs when one of the arteries that supplies the heart muscle becomes blocked. Blockage may be caused by spasm of the artery or by atherosclerosis with acute clot formation.
What does myocardial mean in medical terms?
Medical Definition of myocardial : of, relating to, or involving the myocardium.
What does acute MI mean on ECG?
Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and diaphoresis. Diagnosis is by ECG and the presence or absence of serologic markers.
How do you confirm mi?
Tests available include: Cardiac Troponin I or Troponin T – which are both very sensitive and specific and are the recommended laboratory tests for the diagnosis of MI. Serial testing is recommended in order to confirm or exclude a rise or fall in troponin concentration.
What is the most common cause of acute myocardial infarction?
The most common cause of a myocardial infarction is the rupture of an atherosclerotic plaque on an artery supplying heart muscle. Plaques can become unstable, rupture, and additionally promote the formation of a blood clot that blocks the artery; this can occur in minutes.
What is myocardial damage?
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw.

The word myocardial refers to the heart muscle or ‘myocardium’. Infarction refers to a blockage in blood supply.
What does MI mean in hospital?
A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infarction” means death of tissue due to lack of blood supply.
What is the full meaning of MI?
MI: Commonly used abbreviation for myocardial infarction, otherwise known as a heart attack.
What causes MI?
The causes of myocardial infarction, or a heart attack, all involve some kind of blockage of one or more of the coronary arteries. The coronary arteries provide the heart with oxygenated blood, and if they become blocked, the heart will become oxygen starved, killing heart tissue and causing a heart attack.
What does acute myocardial infarction mean in medical terms?
What is acute myocardial infarction? Acute myocardial infarction is the medical name for a heart attack. A heart attack is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.
What are the signs and symptoms of acute myocarditis?
Symptoms are flulike; in acute myocarditis there is usually pain in the epigastric region or under the sternum (either ischemic, atypical, or pericardial), as well as dyspnea and cardiac arrhythmias. If the condition persists and becomes chronic, there is pain in the right upper quadrant of the abdomen, owing to hepatic congestion.
Are there any silent symptoms of acute myocardial infarction?
However, discomfort may be mild; about 20% of acute MIs are silent (ie, asymptomatic or causing vague symptoms not recognized as illness by the patient), more commonly in patients with diabetes.
How often does an acute coronary syndrome ( mi ) occur?
(See also Overview of Acute Coronary Syndromes .) In the US, about 1.0 million myocardial infarctions occur annually ( 1 ). MI results in death for 300,000 to 400,000 people (see also Cardiac Arrest ). Acute myocardial infarction (MI), along with unstable angina, is considered an acute coronary syndrome.
What are the signs of mi?
Signs and symptoms of MI include: Chest pain lasting longer than a few minutes. Anxiety. Cough. Fainting. Lightheadedness/ Dizziness. Nausea/ Vomiting. Heart palpitations.
What are the types of myocardial infarction?
Myocardial infarction has been classified into types 1 to 5 of which type 4 has subtypes a and b. Type 1 is spontaneous myocardial infarction due to a primary coronary event like plaque rupture. Type 2 is secondary to a supply demand mismatch as in coronary vasospasm, anemia or hypotension .
What is mi treatment?
Medications Given To Treat A Heart Attack or Myocardial Infarction (MI) Include: Aspirin is given by emergency medical personnel immediately after the patient arrives at the hospital. Thrombolytics, also known as clot busters, help in dissolving the blood clot which is blocking the blood flow to the heart.
What are some treatments for myocardial infarction?
The following medications/drugs/procedures are some of the latest treatments for Myocardial infarction: Oxygen. Aspirin. Enoxaparin. Clopidogrel. Glycoprotein IIb/IIIa. Abciximab. Eptifibatide.
