Popis: | The diagnosis of heart failure with preserved ejection fraction is characterized by its complexity, especially for physicians without great experience in comprehensive transthoracic Doppler echocardiography. Peak mitral E-wave (E) velocity has been successfully correlated to invasive left ventricular diastolic pressures in patients with structural heart disease. The aim of the study was to address the accuracy of E in the diagnosis of heart failure with preserved ejection fraction in elderly patients with acute dyspnea.This prospective study included 29 consecutive patients ≥70 years of age with heart failure with preserved ejection fraction and acute dyspnea and 29 controls ≥70 years of age. The final diagnosis was supported by the 2016 ASE/EACVI recommendations.Mean age of the overall population was 85±7 years. E was strongly correlated with left atrial volume index (r=0.72, P0.001) and with peak velocity of tricuspid regurgitation (r=0.77, P0.001). E85cm/s was 90% sensitive and 93% specific in the diagnosis of heart failure with preserved ejection fraction (AUC, 0.95). E/e' (0.95) and E/(e'xs') (0.92) did not perform better.E/e' and E/(e'xs') provide essential diagnostic and prognostic information in heart failure with preserved ejection fraction and deserve to be included in every report of comprehensive transthoracic Doppler echocardiography. E velocity is a very simple and user-friendly parameter that can be used for the sole diagnostic purpose in elderly patients with acute dyspnea by operators without great deal of experience, such as cardiologists without formal training, emergency physicians, intensive care anesthetists, internists and geriatricians. |
