Mid lad shows chronic total occlusion with faint filling of distal lad seen through collaterals, (lmca,lcx, oms, rca are normal) pls suggest stent/med?

Cannot stent: You prob can't stent your mid-LAD as it is already 100% occluded. Good that you have collaterals to feed that downstream muscle. You should be on a statin med (pravastatin, etc) to prevent further atherosclerosis. Add a blood pressure med like Lisinopril if you have high BP. And use meds for angina, but only if you trigger it w/ activity. A daily aspirin is recommended. Any heart attacks?
