The most common symptom of a heart attack, heart attack victims may experience a diversity of symptoms that include: pain, fullness, and/or squeezing sensation of the chest; jaw pain, toothache, headache; shortness of breath; nausea, vomiting, and/or general epigastric (upper middle abdomen) discomfort; sweating; heartburn and/or indigestion; arm pain (more commonly the left arm, but may be either arm); upper back pain; general malaise (vague feeling of illness); and no symptoms (approximately one quarter of all heart attacks are silent, without chest pain or new symptoms and silent heart attacks are especially common among patients with diabetes mellitus).
