New guidelines on pulmonary embolus are out, they provide a framework for escalating therapy based on risk, derived from clinical, imaging, and lab assessment. The at-a-glance document provides a great quick summary. @accintouch.bsky.social www.jacc.org/doi/epdf/10.... www.jacc.org/doi/10.1016/...

I appreciate that in this scientific statement on epicardial coronary physiological measurements, the authors expressly state that using angiographic assessment alone is only slightly better than a coin flip. www.ahajournals.org/doi/10.1161/... #cardiosky @sripalbangalore.bsky.social
