Hi, I am a man 45yo, had hart infarct last year + angioplasty (3 stents), left ventricol got some damage as I arrived very late to the hospital.After one year the echo shows a FE of 47%, they say won`t get far than that probably, due to the delay of the surgery, got no symptoms, sporting aerobics 40min. a day ,feeling good, only during the sleep I wake up sometime feeling high heartrate, say round 80<>100, during daytime is always 70/75, my drug therapy is: cardioaspirin 100mg, metropol 50mg, perindopril 8mg, crestor 20mg.Do I have to expect bad arrhythmias and could my FE increase furhter? also I would like to ask if supplements such as coenzyme q10 and L carnitine are of help in such cases.Many thanks in advance.
