Advice on Whey Protein

I'm 56.Had angioplasty more than 2 years back.I do appx.100 push-ups every day and(used to do200 to 400 before a heart attack).
I'm still continuing my exercises with a cardiologist's permission.Before I see him again,I would like to take an advice from a doctor,Can I take Whey Protein ?
Thank you !

Yesterday,after posting my question and switching off computer,I thought of Mr.Kenkeith,whose answers/advices I have read and found very useful.

I request him to give his opinion regarding my use of Whey Protein.After I stopped taking proteins(after attack and angioplasty),my muscles had started aching.When i started Egg-White,it reduced.
Shall I take W.Protein ?(doing exercise is my obsession)

Thank you !
