Jun 13, 2012 at 21:06 comment added Kevin Buzzard It is well-known that there exists an elliptic curve of analytic rank 0 and algebraic rank 0. Parity conjectures are now theorems in many cases. But if one could rule out the existence of an elliptic curve with analytic rank 2 and algebraic rank 0 this would be a major breakthrough. So your more general question seems to me to be hopelessly out of reach.
Jun 13, 2012 at 18:20 comment added Alex B. Nothing like that it know. Basically, the only things we know are the Gross-Zagier-Kolyvagin results for analytic rank $\leq 1$ and parity results. There is an MO thread concerning the latter: mathoverflow.net/questions/71609/the-parity-conjecture
