TNNI3 and myocardial infarction: Effects of environmental conditions on point-of-care cardiac biomarker test performance during a simulated rescue: implications for emergency and disaster responseIn a simulated rescue of Marshal Islands patients with chest pain flown to Hawaii for intervention, short-term temperature elevation produced falsely lower cTnI results. Some stressed cTnI measurements falsely reported normal levels when control results indicated alert values potentially leading false-negative diagnosis of an acute myocardial infarction.
