AIMS: There is little evidence-based therapy existing for acute heart failure (AHF), hospitalizations are lengthy and expensive, and optimal monitoring of AHF patients during in-hospital treatment is poorly defined. We evaluated a rapid cardiothoracic ultrasound (CaTUS) protocol, combining focused echocardiographic evaluation of cardiac filling pressures, that is, medial E/e' and inferior vena cava index, with lung ultrasound (LUS) for guiding treatment in hospitalized AHF patients.
METHODS AND RESULTS: We enrolled 20 consecutive patients hospitalized for AHF, whose in-hospital treatment was guided using the CaTUS protocol according to a pre-specified treatment protocol targeting resolution of pulmonary congestion on LUS and lowering cardiac filling pressures. Treatment results of these 20 patients were compared with those of a standard care sample of 100 patients, enrolled previously for follow-up purposes. The standard care sample had CaTUS performed daily for follow-up and received standard in-hospital treatment without ultrasound guidance. All CaTUS exams were performed by a single experienced sonographer. The CaTUS-guided therapy resulted in significantly larger decongestion as defined by reduction in symptoms, cardiac filling pressures, natriuretic peptides, cumulative fluid loss, and resolution of pulmonary congestion (P < 0.05 for all) despite a shorter mean length of hospitalization. Congestion parameters were significantly lower also at discharge (P < 0.05 for all), without any significant difference in these parameters on admission. The treatment arm displayed better survival regarding the combined endpoint of 6 month all-cause death or AHF re-hospitalization (log rank P = 0.017). No significant difference in adverse events occurred between the groups.
CONCLUSIONS: The CaTUS-guided therapy for AHF resulted in greater decongestion during shorter hospitalization without increased adverse events in this small pilot study and might be associated with a better post-discharge prognosis.
