email article Transitioning high-sensitivity troponin testing protocols in the emergency department for suspected acute coronary syndrome can have some unintended consequences, studies showed. In a prospective multicenter trial from Australia, patients randomized to a 0/1-hour high-sensitivity cardiac troponin-T (hs-cTnT) protocol unmasked to the care team had similar all-cause mortality and MI at 12 months as those whose early levels were masked and were treated based on the standard protocol of 0/3-hour testing (5.0% vs 3.8%, HR 1.32, 95% CI 0.95-1.83). However, for those with an intermediate elevation in troponin of less than 29 ng/L -- the only group for whom results differed between the two trial arms, with reporting to
