Complications

The chest pain that occurs with angina can make doing some normal activities, such as walking, uncomfortable. However, the most dangerous complication is a heart attack.

Common signs and symptoms of a heart attack include:

• Pressure, fullness or a squeezing pain in the center of your chest that lasts for more than a few minutes
• Pain extending beyond your chest to your shoulder, arm, back, or even to your teeth and jaw
• Increasing episodes of chest pain
• Nausea and vomiting
• Prolonged pain in the upper abdomen
• Shortness of breath
• Sweating
• Fainting
• Impending sense of doom

If you have any of these symptoms, seek emergency medical attention immediately.
