摘要
OBJECTIVES:To assess the prognostic value of lung ultrasound for patients with chronic heart failure.
METHODS:Prospective observational cohort study, in which a lung ultrasound was performed on 54 patients at a heart failure outpatient consultation. Ultrasonography was classified as positive or negative for ultrasound interstitial syndrome depending on the number of B lines observed. Patients were followed up for six months; considering emergency visits, readmissions and deaths due to heart failure as markers of poor prognosis.
RESULTS:53.7% (29) of the patients had ultrasound interstitial syndrome. Among them, 48.3% (14) were readmitted, compared to 16% (4) of those without the syndrome (P=.012). Considering any of the events previously described as end points (readmissions, emergencies and deaths), we found that in the group of patients with ultrasound interstitial syndrome, 55.2% (16) had at least one of these complications, compared to 20% (5) of participants without the syndrome (P=.008).
CONCLUSIONS:Lung ultrasound in the outpatient setting is useful in predicting which patients are at increased risk of heart failure decompensation in the mid-term.
