Heart Attack (Myocardial Infarction)
|
| Definition |
A heart attack (myocardial
infarction) is the death of part of the heart muscle. The pain
associated with a heart attack is typically felt in the chest but
may also be felt in the arms, neck or jaw. The pain may be mild or
severe and may not be relieved by nitroglycerin. In some cases a
heart attack is also associated with shortness of breath and
sweating. If any doubt exists, the person should immediately go to
the hospital or call their doctor.
|
| Causes |
Interruption of blood supply to an
area of heart muscle causes death of heart muscle and results in a
weakened heart.
|
| Treatment |
Both blood tests and
electrocardiography (ECG) are used to diagnose heart attacks.
Treatment usually includes rest and support with heart and pain
medicine. It is important that heart medicines that break down clots
(thrombolytics) be considered as quickly as possible. Some patients
may be considered for a cardiac catheterization and angioplasty or
stent procedure to open the blocked blood vessel responsible for
causing the heart attack.
|
| Comments |
Patients with symptoms of a heart
attack should seek medical attention immediately. If a person is not
seen immediately by a doctor, complications such as an abnormal
heart rhythm, heart failure, or death may result.
