A selection of resources
Myocardial Infarct; diagnosis
NICE obviousily have lots of guidelines around this, I particularly like their "do not" guides which advises against excessive oxygen and for using GTN response as a diagnosis marker. The main NICE guide from 2019 also suggests you can use a single rule out troponin
I find the NICE guidelines a little sparse. The european society of cardiology has much more detailed guidelines.

An open access meta-analysis comparing recognised MI's to those diagnosis later
I may be massively misinterpreting this study, but they seem to conclude mortaility outcomes are the same whether you diagnosis an MI or not?
This useful paper suggesting that can get away without troponin for the very low risk group.
