Myocardial infarction in which
the anterior wall of the heart is involved
. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction. [ MESH:D056988 ]
What is anterolateral infarct?
Anterolateral infarcts
result from the occlusion of the left main coronary artery
, and changes appear in leads V5, V6, I, aVL, and sometimes V4. A true anterior infarct doesn’t involve the septum or the lateral wall and causes abnormal Q waves or ST-segment elevation in leads V2 through V4.
What does anterior myocardial infarction mean?
An anterior wall myocardial infarction occurs
when anterior myocardial tissue usually supplied by the left anterior descending coronary artery suffers injury
due to lack of blood supply.
How is an anterior myocardial infarction treated?
Cardiac catheterization and immediate coronary artery bypass grafting in
the first hours of anterior myocardial infarction can be done safely and may reduce in-hospital and long-term mortality.
What causes anterior myocardial infarction?
An anterior myocardial infarction results from
occlusion of the left anterior descending coronary artery
. This can cause an ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.
What is the best treatment for myocardial infarction?
All patients with a suspected myocardial infarction should be given
aspirin
. It is a powerful antiplatelet drug, with a rapid effect, which reduces mortality by 20%. Aspirin, 150-300 mg, should be swallowed as early as possible.
What are the types of myocardial infarction?
A heart attack is also known as a myocardial infarction. The three types of heart attacks are:
ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI)
Is a sinus rhythm good?
Normal sinus rhythm is defined as
the rhythm of a healthy heart
. It means the electrical impulse from your sinus node is being properly transmitted. In adults, normal sinus rhythm usually accompanies a heart rate of 60 to 100 beats per minute.
Can stress cause a myocardial infarction?
Stress can cause heart problems in several different ways. First,
an excess of stress hormones can cause
a “myocardial infarction,” otherwise known as a heart attack. A myocardial infarction occurs when a blockage forms in one of the arteries that supplies oxygenated blood to the heart muscle.
What happens in 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 should I monitor after myocardial infarction?
Once hospitalized, the patient with acute MI should be continuously monitored by
electrocardiography
and the diagnosis of acute MI confirmed by serial ECGs and measurements of serum cardiac markers of myocyte necrosis, such as creatine kinase isoenzymes or cardiac specific troponin T or I.
What are the complications of myocardial infarction?
- Disturbance of rate, rhythm and conduction. …
- Cardiac rupture. …
- Heart failure. …
- Pericarditis. …
- Ventricular septal defect. …
- Ventricular aneurysm. …
- Ruptured papillary muscles. …
- Dressler’s syndrome.
How can you prevent myocardial infarction?
- Stop smoking. If you smoke, quit. …
- Choose good nutrition. A healthy diet is one of the best weapons you have to fight cardiovascular disease. …
- High blood cholesterol. …
- Lower high blood pressure. …
- Be physically active every day. …
- Aim for a healthy weight. …
- Manage diabetes. …
- Reduce stress.
What tests confirm a diagnosis of myocardial infarction?
- Electrocardiogram (ECG). This first test done to diagnose a heart attack records electrical signals as they travel through your heart. …
- Blood tests. Certain heart proteins slowly leak into your blood after heart damage from a heart attack.
How do you identify a myocardial infarction on an ECG?
One of the most significant findings of myocardial infarction is
the presence of ST segment elevation
. The ST segment is the part of the ECG tracing that starts at the end of the S wave and ends at the beginning of the T wave. The point where the end of the Q wave and the ST segment meet is called the J point.
What is myocardial damage?
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.
