What can occur when there is an injury to the heart muscle it is also known as a myocardial infarction and it is caused when blood clots block the flow of blood through the coronary artery?
A heart attack happens when one or more of your coronary arteries suddenly becomes blocked, stopping the flow of blood to the heart muscle and damaging it – causing a heart attack.
What happens when heart muscle is damaged?
In some cases of heart failure, your heart muscle may become damaged and weakened, and the ventricles stretch (dilate) to the point that the heart can’t pump blood efficiently throughout your body. Over time, the heart can no longer keep up with the normal demands placed on it to pump blood to the rest of your body.
What happens to the heart during a heart attack?
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. Heart muscle damaged by a heart attack heals by forming scar tissue.
What causes myocardial injury?
Causes of myocardial ischemia Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).
What are the warning signs of a myocardial infarction?
Symptoms
- 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.
- Cold sweat.
- Fatigue.
- Lightheadedness or sudden dizziness.
What is the best treatment for myocardial infarction?
How is acute myocardial infarction treated?
- Blood thinners, such as aspirin, are often used to break up blood clots and improve blood flow through narrowed arteries.
- Thrombolytics are often used to dissolve clots.
How long can you live with 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.
What is the main cause of a myocardial infarction?
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 tests confirm a diagnosis of myocardial infarction?
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period.
