Dad had heart cath on Tues. 100% block on one side, 20% on other. No stents, meds to treat. Since, has chest pain with movement and headache.

Cath. Need to talk with pts. doctor for specifics re this pt. In general from what you sent, the expectation would be pt. managed with meds unless they don't give adequate symptom relief. The headache likely from nitrates or calcium blockers. Pts. meds need to be titrated to symptom satisfaction if possible.
