Hi Sir, I underwent angioplasty last december due to AWMI and the block percentage was 100% according to doctors it was due to SVD. Now my ef value is 30 and currently I am on Clopilet A 150 mg OD, Aztor 40mg OD, Nitocontin 2.6mg BD, Acitrom 2mg OD, Revolol XL 50mg OD, Ramistar H 2.5mg OD. And I have been regularly walking for close to 45 mins, how to increase EF value?
