Abstract

Objective We evaluated the prognostic value of subclinical congestion assessed by lung ultrasound (LUS) in patients admitted for ST segment elevation myocardial infarction (STEMI).

Methods This was a multicentre study that prospectively enrolled 312 patients admitted for STEMI without signs of heart failure (HF) at admission. LUS was performed during the first 24 hours after revascularisation and classified patients as having either wet lung (three or more B-lines in at least one lung field) or dry lung. The primary endpoint was a composite of acute HF, cardiogenic shock or death during hospitalisation. The secondary endpoint was a composite of readmission for HF or new acute coronary syndrome or death during 30-day follow-up. Zwolle score was calculated in all patients to assess predictive improvement by adding the result of the LUS to this score.

Results 14 patients (31.1%) in the wet lung group presented the primary endpoint vs 7 (2.6%) in the dry lung group (adjusted RR 6.0, 95% CI 2.3 to 16.2, p=0.007). The secondary endpoint occurred in five patients (11.6%) in the wet lung group and in three (1.2%) in the dry lung group (adjusted HR 5.4, 95% CI 1.0 to 28.7, p=0.049). Addition of LUS improved the ability of the Zwolle score to predict the follow-up composite endpoint (net reclassification improvement 0.99). LUS showed a very high negative predictive value in predicting in-hospital and follow-up endpoints (97.4% and 98.9%, respectively).

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.
