What happens to the body during a myocardial infarction?
A myocardial infarction (MI), commonly known as a heart attack, occurs when a portion of the heart is deprived of oxygen due to blockage of a coronary artery.
Coronary arteries supply the heart muscle (myocardium) with oxygenated blood.
Without oxygen, muscle cells served by the blocked artery begin to die (infarct)..
Can myocardial infarction be cured?
Even if you’ve been treated for a prior heart attack or if you’ve had other treatments for coronary artery disease, a heart attack CAN happen again. Treatments such as medications, open heart surgery and interventional procedures DO NOT cure coronary artery disease, so it is still important to lead a healthy lifestyle.
What is a Type 2 heart attack?
Type 2: A heart attack occurring when the heart needs more oxygen than it can get. This type of heart attack is an oxygen demand problem, resulting from higher need for blood flow.
What happens when a heart attack kills you?
The ventricles may flutter or quiver (ventricular fibrillation), and blood is not delivered to the body. In the first few minutes, the greatest concern is that blood flow to the brain will be reduced so drastically that a person will lose consciousness. Death follows unless emergency treatment is begun immediately.
How do I know myocardial infarction on ECG?
The ECG findings of an acute anterior myocardial infarction wall include:ST segment elevation in the anterior leads (V3 and V4) at the J point and sometimes in the septal or lateral leads, depending on the extent of the MI. … Reciprocal ST segment depression in the inferior leads (II, III and aVF).
How long can you live with myocardial infarction?
About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
Can you survive a myocardial infarction?
It is a serious and life-threatening condition. Around one quarter of patients die from the acute event, half of these before the hospital is reached. Survivors have a higher risk of recurrent heart attacks or cardiac death, and a further 10% die within two years. Only 50% of initial survivors are alive at 10 years.
Can you live a long life after heart attack?
After a first heart attack, most people go on to live a long, productive life. However, around 20 percent of patients age 45 and older will have another heart attack within five years of their first.
What is the main cause of a 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.
Can you have a myocardial infarction and not know it?
You can have a heart attack and not even know it. A silent heart attack, known as a silent myocardial infarction (SMI), account for 45% of heart attacks and strike men more than women.
What are the 5 types of myocardial infarction?
The five types of acute MI compose five separate situations that produce myocardial ischemia and myocardial-cell death:A primary coronary event, such as plaque rupture or dissection.A problem of oxygen supply and demand, such as coronary spasm, coronary embolism, arrhythmia, anemia, or hypotension.More items…•
How does a heart attack kill instantly?
A heart attack stems from a circulation, or “plumbing,” problem of the heart, according to the Sudden Cardiac Arrest Association. It happens when a sudden blockage in a coronary artery severely reduces or cuts off blood flow to the heart, damaging heart muscle.
What is the difference between a heart attack and a massive heart attack?
It’s just like a regular heart attack, but it affects more of the organ. Physicians might use the phrase “massive heart attack” to describe a myocardial infarction that destroys a large amount of tissue—say, more than 25 percent of the total heart muscle. Ken Lay may not have died from a “massive heart attack” at all.
What are the signs of old myocardial infarction?

What does a mini heart attack feel like?
Mini heart attack symptoms include: Chest pain, or a feeling of pressure or squeezing in the center of the chest. This discomfort may last several minutes: It may also come and go. Pain may be experienced in the throat. Symptoms may be confused with indigestion or gastroesophageal reflux disease (GERD).
What is considered a mild heart attack?
A mild heart attack affects a relatively small portion of the heart muscle, or does not cause much permanent heart damage. This is because the blockage in a coronary artery occurs in a small artery that supplies a small portion of the heart muscle; does not completely block blood flow to the heart; or lasts briefly.
Are there symptoms before a massive heart attack?
Common heart attack signs and symptoms include: Pressure, tightness, pain, or a squeezing or aching sensation in your chest or arms that may spread to your neck, jaw or back. Nausea, indigestion, heartburn or abdominal pain. Shortness of breath.
