Subclinical congestion assessed by lung ultrasound in ST segment elevation myocardial infarction
Main findingResult — go to the resultAdjusted relative risk 6.0 95% CI 2.3–16.2Authors' conclusion
Early subclinical pulmonary congestion identified by LUS in patients with Killip I STEMI at hospital admission is associated with adverse outcomes during hospitalisation and 30-day follow-up.
Study context
- Population
- Patients admitted for segment elevation myocardial infarction (STEMI) without signs of heart failure (HF) at admission; Lung ultrasound (LUS) within 24 hours after revascularisation
- Participants
- 312 patients
- Exposure
- Wet lung vs dry lung on LUS
- Outcome
- Composite of:
- Acute HF
- Cardiogenic shock
- Death
- Follow-up
- During hospitalisation
