Lung ultrasonography and acute cardiogenic dyspnea. Lung ultrasonography for identification of acute cardiogenic dyspnea in hospitalized patients

      Аннотация: Acute dyspnea (AD) is a common complaint in a hospital unit and, frequently, differential diagnosis is challenging, despite the acquirement of diverse methodologies. Lung ultrasonography (LUS) has shown its usefulness at identifying DA of cardiogenic origin. It is a prospective and longitudinal cohort of patients at the emergency unit and inmates at the hospital unit, complaining of AD. They were evaluated by Framingham Risk Score (FRS) for cardiac insufficiency (CI), and were submitted to the following complementary tests including LUS. 118 patients were classified according to presence or absence of CI by physical examination. Out of 109 cases, 55% had CI. These patients were older, men, hypertensive , diabetic , with chronic renal insufficiency and with higher adapted Killip classification and functional class. They presented more pulmonary interstitial edema on LUS. Independent predictors on interstitial pulmonary edema detection by LUS in these patients were male gender, diabetics and with reduced ejection fraction . It was concluded that LUS is an useful tool and with reproducibility to identify AD of cardiogenic origin.
