| drugs that increase risk of statin related myopathy |
gemfibrozil, niacin, verapamil, amiodarone, CSA, anti-fungals, HIV drugs, grapefruit juice -- decrease dose of statin 50% |
| incidence of rupture with lytics |
no increase if lytics given early, but it can occur early if lytics given late (>14 h) |
| absolute contraindications to lytics |
any ICH, known AVM, known IC neoplasm, ischemic CVA within 3 months, active bleeding, CHI or facial trauma within 3 months, suspected dissection |

no |
