Hello aspirant,

No, you cannot do MD (Doctor of Medicine) after B.Sc or M.Sc Cardiology.

Candidates must appeared in entrance exam like NEET UG and secured MBBS seat and completed it from a recognised College or University are only eligible to appear for NEET PG and then to get MD seat.

So with just B.Sc or M.Sc in Cardiology you are not eligible for MD courses.
