<h3>What is heart attack ?</h3>
Myocardial infarction, or heart attack, is the death of cells in a region of the heart muscle due to the formation of a clot that stops blood flow in a sudden and intense way.
<h3>Symptoms</h3>
The main symptom of a heart attack is pain or discomfort in the chest region, which can radiate to the back, face, left arm and, rarely, the right arm. This discomfort is usually intense and prolonged, accompanied by a feeling of heaviness or tightness on the chest. These signs can be accompanied by excessive sweating, pallor, and a change in heart rate.
With this information, we can conclude that a series of diagnoses and monitoring of symptoms can be performed, but the patient must follow the recommendations.
