What are the complications of a heart attack?

Although chest pain or pressure is 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)
• No symptoms (Approximately one quarter of all heart attacks are silent, without chest pain or new symptoms. Silent heart attacks are especially common among patients with diabetes mellitus.)
