BACKGROUND: B-lines have been associated with adverse clinical outcomes in patients with heart failure (HF) when found at hospital discharge or during outpatient visits. Whether lung ultrasound (LUS) assessed B-lines may predict in-hospital mortality in patients with acute HF is still undetermined. AIM: To evaluate the association between B-lines on admission and in-hospital mortality among patients admitted with acute HF. METHODS: Hand-held LUS was used to examine patients with acute HF. LUS was performed in eight chest zones with a pocket ultrasound device and analyzed offline. The association between B-lines and in-hospital mortality was assessed using Cox regression models. RESULTS: We included 62 patients with median age 56 years, 69.4% men, and median left ventricle ejection fraction 25%. The sum of B-lines ranged from 0 to 53 (median 6.5). An optimal receiver operating characteristic-determined cut-off of ≥19 B-lines demonstrated a sensitivity of 57% and a specificity of 86% (area under the curve 0.788) for in-hospital mortality. The incremental prognostic value of LUS when compared with lung crackles or peripheral edema by integrated discrimination improvement was 12.96% (95% CI: 7.0-18.8, P = 0.02). Patients with ≥19 B-lines had a 4-fold higher risk of in-hospital mortality (HR 4.38; 95% CI: 1.37-13.95, P < 0.01). CONCLUSION: In patients admitted with acute HF, point-of-care LUS measurements of pulmonary congestion (B-lines) are associated with in-hospital mortality.

Resumen: El infarto de miocardio es causa importante de muerte y discapacidad en todo el mundo. Es secundario al desequilibrio entre la relación aporte/consumo de oxígeno miocárdico y tiene características clínicas propias. En este artículo se comunica el caso clínico de un paciente con múltiples factores que generaron un desequilibrio en la relación aporte/consumo de oxígeno del miocardio, además de elevación significativa del segmento ST en el electrocardiograma y marcada elevación de la troponina I. Todos estos cambios revirtieron con el inicio del manejo médico de los factores que contribuyeron a este desequilibrio.
Abstract: Myocardial infarction (MI) is a major cause of death and disability worldwide. Type 2 MI is secondary to an imbalance in myocardial oxygen delivery/consumption relationship and has its own clinical characteristics. We report the case of a patient with multiple factors that created an imbalance in the myocardial oxygen delivery/consumption relationship and also had significantly ST segment elevation on the electrocardiogram and marked elevation of troponin I. All these changes reversed with the onset of medical management of the factors that contributed to this imbalance.
