As per authorities in the AIIMS, the VP had to undergo an angiography test following which a stent was placed to treat his condition.
The test was necessary as Naidu's blood pressure and sugar levels were found higher than normal.
"He (Naidu) was brought to the hospital in the evening. He is fine and will undergo certain tests. He will be discharged tomorrow (Saturday)," said a senior doctor.
However, the doctors at AIIMS said there was nothing to worry and that he would be discharged by Saturday afternoon.
Mr Naidu was admitted to AIIMS at around 8 am in the Cardio-Neuro Centre.
The procedure on him was carried out under the supervision of Cardiology Professor at the All India Institute of Medical Sciences, Dr Balram Bhargava.
Tests had pointed to some problems related to the heart, following which the procedure was carried out on Friday.
