Had to find a more recent copy of Lilly's to review. I am glad to see they have substantially updated it since I was a student. If you read the 6th edition, you should be well prepared at the student level.
If you can invest in a copy AND find time to read it, the Manual of Cardiovascular Medicine by Brian Griffin will give you more on clinical trials, management, and procedures. Usually meant as a text more for residents and junior cardiology fellows, though.
There have been multiple recent updates to AHA/ACC guidelines on various cardiovascular diseases (and JNC 8 for BP [+associated recommendation controversy raised by the SPRINT trial results] and ATP IV for cholesterol). Those are freely available online. Please consider supplementing what you've learned with those as needed.
