Patient discussion about attack

Q. what should I do to prevent heart attack?

A. The American Heart Association recommends that heart attack prevention begin by age 20. This means assessing your risk factors and working to keep them low. For those over 40, or those with multiple risk factors, it’s important to calculate the risk of developing cardiovascular disease in the next 10 years. Many first-ever heart attacks or strokes are fatal or disabling, so prevention is critical. The sooner you begin comprehensive risk reduction, the longer and stronger your heart will beat.
