The current evaluation of acute heart failure (HF) does not allow an adequate prediction of its evolution. The electrical bioimpedance (BI) allows knowing the state of blood volume, until now only with fixed equipment. We have developed and validated a portable and wireless device to measure BI at the ankle (IVOL). The objective of the study is to know the long-term prognostic value of the point measurement of BI with IVOL in patients with acute HF. ⋯ BI values measured with IVOL may be an independent predictor of long-term mortality in patients hospitalized for acute HF. This prognostic value is maintained in patients without preserved LVEF function and with RV dysfunction.

Transbronchial needle aspiration guided by endobronchial ultrasonography (EBUSTBNA) has the disadvantage of sometimes offering samples of an unsuitable size for an accurate histo-molecular diagnosis. Transbronchial mediastinal cryobiopsy (CRYOEBUS) is a very novel and additional technique to EBUS-TBNA that allows us to obtain larger and quality samples, improving diagnostic performance. ⋯ The CRYO-EBUS technique is cost-effective and safe, and is superior to EBUS-TBNA. Future studies may confirm our findings.
