hello, back in 9/13/2013, had a heart attack, as a result my left ventricular @ 12% ejection fraction. After a difibulater and one of my blood thinner uses of effient...my question I stopped taking effient for 2 weeks now, my present cardiologist told me it would be up to me to decide that, seeing my last stent was in 1/1/2016...Im feeling maybe i should start again taking effient again, til I get a second opinion , rather than making this choice alone, what is your opinion ?
