Hello Aspirant,
Hope you are doing great. Your interest should be the only factor. If you prefer the field of cardiology, choose cardiac care over the operating room if those are your only two choices. If money is your deciding factor and interest is not a major consideration, you should choose the operating room because it may pay you more than cardiac care.
One of the options is to work as an operation room technician. People who choose to work as operation theatre assistants are always in demand because every hospital that has an operating room needs them.
ALL THE BEST
