💥Increased #COVID19 mortality with CVD
💥Association between elevated troponin and mortality
💥#COVID19 + elevated troponin -> older patients, more co-morbidities, higher acuity
3/6
💥ACC: Measure troponin & BNP if considering ACS / HF clinically
💥Based on studies, ?consider using troponin as prognostic marker
💥ACS: GDMT, consider cath lab staff exposure, ?fibrinolytics in low risk ACS
