is that true?
In myocardial infarction the first symptom is often the most pressing constrictor chest pain, which often extends to the left arm, neck, jaw or the area between the vanes.
Nausea and vomiting are some of the symptoms although not the most common ones.
The textbook symptoms are crushing chest pain which may radiate to the left arm and jaw, dizziness, lightheadedness, profuse sweating, difficulty breathing, sense of doom.
Of course not everyone presents the same.
