WEDNESDAY, April 26, 2006 (HealthDay News) -- A heart attack occurs when blood flow to the heart is restricted, typically by a blockage in an artery. Most people know that if they have unexplained chest pain, they should seek immediate medical help. But there are other signs that could signal a heart attack.
According to the University of Maryland Medical Center, any feeling of pain or pressure in the center of the chest -- including squeezing, a feeling of fullness or discomfort -- that lasts for more than a few minutes could be a sign of a heart attack.
Shortness of breath, nausea, sweating, dizziness, fatigue and paleness are all additional signs of a possible heart attack. Some people may experience all of these symptoms, while others only one or a combination of a few.
If you or someone you know has one or more of these symptoms, seek medical attention immediately.
