Myocardial infarction

Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Often it is in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, or feeling tired. About 30% of people have atypical symptoms. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock, or cardiac arrest.

The video was very informational regarding what goes on during an MI. Although the video was explainatory, it lacked proper treatment from the EMS providers. The patient could have had improvements with his condition if he was approved of taking baby asprin, perscribed nitroglycerin, and positive pressure ventilation (when resporations were inadequate). Nice video with an inside visual of pathology relating to an MI.
