Cardiac events are a common cause of peri-operative morbidity. Cardiopulmonary exercise testing can objectively assess risk, but it does not quantify myocardial ischaemia. With appropriate dietary preparation to suppress basal myocardial glucose uptake, positron emission tomography with 18 F-fluorodeoxyglucose can identify post-ischaemic myocardium, providing an attractive complement to exercise testing. ⋯ Twenty-one participants proceeded to surgery: myocardial injury or infarction was diagnosed in three participants, two of whom had positive or equivocal positron emission tomography but negative myocardial perfusion imaging. We have shown that pre-operative cardiac positron emission tomography after cardiopulmonary exercise testing is feasible; protocol deviations were minor and did not affect image quality. Our findings warrant further investigation to compare the diagnostic utility of cardiac positron emission tomography imaging with standard pre-operative stress tests.

We examined the prevalence of novel acronyms in the titles of anaesthetic and related studies and the response of anaesthetists to them. We separately analysed trainee-led research projects in the UK supported by the Research and Audit Federation of Trainees (RAFT), and a 10-year cohort of papers identified using the PubMed literature search tool. ⋯ Our results show that while acronyms themselves are sometimes considered memorable, they do not aid recall of topics and are, in general, not considered helpful. There has been an increase in the prevalence of acronymic titles over 10 years, and in the complexity of acronyms used, suggesting that there is currently a selective pressure favouring the use of acronyms even if they are of limited benefit.
