A heart attack is often referred to as the "silent killer" because you may not experience symptoms, or they may seem so minor that you don't recognize them in time. But if you remain aware of possible symptoms, you can increase your chances of survival.
Here are the most common symptoms:
Pressure, squeezing, fullness in the chest
Pain that lasts for more than a few minutes
Chest discomfort that comes and goes
May feel like bad indigestion or a tight band around your chest, or a heavy load is on your chest
