Immediate vs Delayed Intervention for NSTEACS

An early invasive strategy is recommended for high risk non-ST elevation acute coronary syndrome (ST/T wave changes, ongoing symptoms, or troponin rise) but how early is early? The French ABOARD study randomised 352 patients to an early (median time of randomisation to sheath insertion 70 mins) or delayed (21 hours) strategy. No difference in the primary outome measure of troponin elevation was observed. Good news for busy cardiologists who won’t have to get up at night for this type of patient.
