简要总结
Left ventricular ejection fraction (LVEF) is a parameter that should be evaluated rapidly to the patients, admitted to the emergency department with shortness of breath. The investigators aimed to investigate correlation between LVEF and 4 different mitral valve movements which alternate to the classical LVEF assessing methods and evaluate these methods can be used or not in the emergency department.
详细描述
A prospective observational study was conducted in an acutely dyspneic patients with receiving echocardiagraphy by the chief physicians. Measurements were performed before echocardiography lab by the physician who conducted the survey in the emergency department. In parasternal long axis view mitral valve E-Point Septal Separation (EPSS) M-Mod measurements and mitral valve anterior leaflet and septal distance (P-ALSS) B-Mod measurements and in apical four chamber view mitral valve anterior leaflet and septal distance (A-ALSS) B-Mod measurements and distance between mitral valve anterior and posterior leaflets (MVLS) B-Mod measurements were acquired as the minimum distance in diastole. LVEF of patients were measured by cardiologist. Correlation of the all values between LVEF and sensitivity, specificity, and likelihood probabilities were calculated.

结局指标
主要结局
Dyspneic patients were evaluated for their left ventricular ejection fraction by new methods with using transthoracic echocardiography.
时间窗: up to 2 hours after admitting to the emergency department
New methods are described: First measurement is distance between mitral valve anterior leaflet and septum in early diastole in the parasternal long axis view m-mode in millimeter.second measurement is distance between mitral valve anterior leaflet and septum in early diastole in the parasternal long axis view b-mode in millimeter. third is the distance between mitral valve anterior leaflet and septum in the apical four chamber view b-mode in millimeter. forth is the distance between mitral valve anterior and posterior leaflet in apical four chamber b-mode in millimeter.
