Considering that you are targeting an MFin course, your courses (Economics & accounting) as well as your experience as an equity analyst come in handy.
Your GPA and work-experience are pretty impressive, and being an international student does give you some leverage.
Schools are keen on having a level of diversity in their class profiles, hence your bio-medical background acts as a differentiator for you.
However ,MSc in Finance courses are extremely competitive programs and hence your lack of a financial/quantitative background may turn out to be a challenge.

-Why do you want to switch to finance?
-What are your short term goals?
-How will the MSc.Finance take you closer to your short term goals?
With a 720+ GMAT score, you should have a good shot at some of the Top 20 B-Schools.
As far as MIT’s MSc in Finance program is concerned, you should know that it is one of the most sought-out B-Schools and has a paper thin acceptance rate.
