"She has made good progress and all her vital parameters are fine," Seth said.
Ms Dikshit wanted to resume work from Friday, but doctors advised her to take rest till Sunday and resume work from Monday.
"I have advised her that she should take rest at least till the weekend," he said, adding that the Chief Minister will be called to the hospital for regular check-ups.
The angioplasty procedure was carried out on 74-year-old Dikshit on Tuesday.
