Each year, thousands of Canadians die from myocardial infarction, also called heart attack, due to failure to promptly initiate medical treatment. Therefore, it is crucial to recognize the signs and symptoms of the condition in order to react quickly to limit the consequences.
Myocardial infarction occurs when a blood clot blocks an artery of the heart, thus decreasing the supply of oxygen to the heart’s cells. The main symptom of myocardial infarction is the sudden onset of intense pain (burning, tightness, pressure, and heaviness) in the chest, which cannot be relieved by resting. Pain can spread to the neck, lower jaw, throat, shoulders, back, or arms (especially the left one).
