I had been diagnosed for Heart Blockage with E.F. at rest at 58 and after Exercise also at 58 around. I had been advised for immediate Angiography and further angioplastry/open heart surgery by one of the Doctor in renowned Hospital of North Delhi. I contaced Dr. Mohan Nair, and he done the Echo himself and found the E.F. at 75 after exercise and was given a clean chit for not going any kind of invasive treatment. This E.F. at 75 was confirmed by another lab as well. I have been saved for going into wrong hands and spoiling my life by this great great Dr. Mohan Nair. Strongly advice heart patients to have a second opinion by Dr. Mohan Nair.
