Respected Sir, My father (Sh R P Vasudeva) had undergone through an angiography and angioplasty at IGMC Shimla, on 21st February, 2017. Two stents were implanted due to the blockage in two arteries (80% and 68%). However, after the stent placement, my father has been experiencing pain inside his chest after walking or exertion. The pain disappears after having rest. He has been facing this problem since the placement of stents. He had also visited the concerned doctor twice to discuss this problem, after a week and after a month of stent placement, but you said that I could be due to some other reasons. I would be most grateful if you could offer some advice regarding this matter.
