Inferior wall STEMI with lesion in the left circumflex artery with separate ostium

A 60 yo with a  h/o of HTN and smoking came in due to chest pain?

Figure 1

This is sinus rhythm (~62 bpm) with ST elevations in III/aVF/II and V6. There  are ST depressions in aVL/I and V2/V1/V3. All consistent with inferior wall ST elevation myocardial infarction.

Patient was brought immediately to the cath lab. It showed a non-dominant right coronary artery that is patent. The left anterior descending artery (LAD) and left circumflex (LCx) had separate ostia. The LAD had minimal disease. There is 100% occlusion in the LCx and intervention was done. Pt was discharged after a few days.
