(Myocardial Infarction - MI)

If you think you are having a heart attack,
please do not waste time reading this!
Call 911 Immediately


A heart attack is called a myocardial infarction, or MI. It results from an abrupt reduction of coronary blood flow. You can see the coronary arteries on the illustration. If any of these become blocked a heart attack will follow.

A heart attack is primarily a LV disease(left ventricular--left side lower chamber of heart). Two-thirds of patients feel symptoms days to weeks before the event.


Symptoms & Signs

The early signs--days to weeks before--include angina (chest pain), shortness of breath or fatigue; although, some folks do not have symptoms. Please see our CALL 911, IF...page for symptoms for men and women--they can differ!

When brought to the emergency room, the patient is usually restless, apprehensive, pale, diaphoretic and in severe pain. Arrhythmias are common.

In a typical MI the diagnosis is evident from the history, confirmed by an initial ECG and emzyme changes (as noted from blood work).

In treatment, physicians want to relieve distress, limit the size of the infarct, reduce cardiac work, and treat any complications.

MI is an acute medical emergency, demanding rapid diagnosis and treatment.
