kidney problem as such. On admission in AIIMS his serum
Creatinine value was 2 but doctor in AIIMS, New Delhi gave the reason as heart failure but the values remained as it is till today. Today it is 1.9. Please tell what to do. His water intake is 1 litre daily and daily he has been implanted with CRT-D device on account of heart failure.
