1.Causes
Over time, cholesterol and a fatty material called plaque can build up on the walls inside blood vessels that take blood to your heart, called arteries. This makes it harder for blood to flow freely. Most heart attacks happen when a piece of this plaque breaks off. A blood clot forms around the broken-off plaque, and it blocks the artery.
2.Symptoms
You may feel pain, pressure, or discomfort in your chest. You could be short of breath, sweat, faint, or feel sick to your stomach. Your neck, jaw, or shoulders might hurt. Men and women can have different symptoms. Men are more likely to break out in a cold sweat and to feel pain move down their left arm.
