Description
Summary:Conventional echocardiography is the technique of choice for assessing left ventricular function and the presence of structural heart disease in patients with heart failure. The aim of this study was to assess the diagnostic performance of handheld ultrasonography performed by a medical internist on patients with a clinical diagnosis of heart failure. Cross-sectional observational study of 212 patients diagnosed with heart failure in a hospital center. A medical internist with basic training in echocardiography performed an examination using handheld ultrasonography and semiquantitatively assessed several variables. The patients’ left ventricular systolic function was assessed, along with the cavity dimensions, significant valvular heart disease, pericardial effusion and the diameter of the inferior vena cava. The examination using handheld ultrasonography was conducted in less than 6min. The agreement between the diagnoses of the medical internist and the expert echocardiographist was very good (k>0.81) for the diameter, hypertrophy and left ventricular systolic function, valvular regurgitation, pericardial effusion and diameter of the inferior vena cava. Handheld echocardiography performed by a medical internist, as an extension of the physical examination of patients with heart failure, is a valid and safe test that helps increase the diagnostic performance. La ecocardiografía convencional es la técnica de elección para valorar la función del ventrículo izquierdo y la presencia de cardiopatía estructural en pacientes con insuficiencia cardiaca. El objetivo del estudio ha sido valorar el rendimiento diagnóstico de la ecografía de bolsillo realizada por un médico internista en pacientes con diagnóstico clínico de insuficiencia cardiaca. Estudio observacional transversal de 212 pacientes con diagnóstico de insuficiencia cardiaca en un centro hospitalario. Un médico internista con formación básica en ecocardiografía realizó una exploración mediante ecografía de bolsillo y valoró, de forma semicuantitativa, diferentes variables. Se valoraron la función sistólica del ventrículo izquierdo, dimensión de cavidades, valvulopatías significativas, derrame pericárdico y el diámetro de la vena cava inferior. La exploración mediante ecografía de bolsillo se realizó en menos de 6min. La concordancia entre los diagnósticos del médico internista y el ecocardiografista experto fue muy buena (k>0,81) para el diámetro, hipertrofia y función sistólica del ventrículo izquierd
