Warning Signs of Heart Attack

Chest Discomfort

Most heart attacks involve discomfort in the centre of the chest that lasts more than a few minutes, or the pain and discomfort go away and come back. It can feel like uncomfortable pressure, squeezing, fullness, or pain. Some heart attacks show up suddenly, and they are unpredictable. But many people have warning signs and symptoms for hours, days, or even weeks in advance.
