Routine CT coronary angiography after MI rule-out did not prevent MI or cardiac death
TARGET-CTCA randomised 3170 ED patients with MI excluded but troponin above 5 ng/L to outpatient CT coronary angiography or standard care, with no difference at three years. Also: protocolised early mobilisation in ventilated patients, online ECG teaching for occlusion MI patterns, and a Baxter vasopressin recall.
The edition in brief
TARGET-CTCA enrolled 3170 patients at 14 UK emergency departments in whom myocardial infarction had been ruled out but high-sensitivity troponin exceeded 5 ng/L, marking intermediate risk. Outpatient CT coronary angiography-guided care did not reduce myocardial infarction or cardiac death over a median three years (7.1% vs 7.3%, adjusted HR 0.95, 0.73 to 1.23). Routine CT after a negative rule-out is not supported; risk-factor treatment and clinical follow-up remain the priority. The EVER trial in five Korean ICUs found a structured six-step early mobilisation programme for ventilated patients with sepsis or respiratory failure did not improve function at ICU discharge or at 12 months, despite earlier and more mobilisation. A German trial of 103 paramedics and emergency clinicians found a 30-minute curated online video and podcast module improved recognition of high-risk ACS ECG patterns more than print materials (55% to 65.5% vs 57% to 60%). FDA lists a Class II recall of Baxter's premixed vasopressin 40 units in 100 mL for manufacturing-practice deviations.
Protocolised early mobilisation did not improve function after ventilation
Keep mobilising ventilated patients, but do not expect a mobilisation protocol alone to improve function at discharge or 12 months.
Curated online teaching improved recognition of occlusion MI patterns
Use short curated online modules to teach high-risk ACS ECG patterns to paramedics and ED staff.
FDA Class II recall: Baxter premixed vasopressin
ICUs stocking Baxter premixed vasopressin should check lots against the FDA recall and have a compounded alternative ready.
Occlusion MI patterns that do not meet STEMI criteria
Know the occlusion MI patterns that lack ST elevation, and call cardiology early when you see one.
TARGET-CTCA: no benefit from routine CT after MI rule-out
After MI is ruled out in the ED, do not order routine CT coronary angiography; treat risk factors and test only for ongoing symptoms.
