Serial troponin testing and 'binary diagnostics' are part of a now outdated paradigm. They have important limitations. In this talk I discuss how we can move to a new paradigm, a new world. This is a world that embraces probability and uncertainty. It's a world where uncertainty can be shared with patients to facilitate individualized shared decision making. It's a world where the patient's individual characteristics can guide the treatment we prescribe. It's a world where care is provided wherever the patient is, not wherever the hospital happens to be. It's a world where the diagnostic tests can improve themselves over time using machine learning. That world is here. The Troponin-only Manchester Acute Coronary Syndromes (T-MACS) rule opens up a whole new world of possibilities for ACS diagnosis. In this talk I illustrate exactly how exciting that future looks.
