Artery heart blockage mild,what are the risks of having a heart attack? thanks

About 20% over 10y: If you have ever had a heart attack before, and you are not having major heart symptoms now, then your risk for a heart attack or stroke over the next 10 yrs is about 20%. Taking 40-80 mg of atorvastatin daily would decrease risk to about 10%. Visit my website, http://CardioGauge.com for info about calculating risk for heart attack and stroke. Good luck!
