Ecocardiograma como ferramenta da emergência.
In 79 patients, the noninvasive measurements of stroke volume (r=0.83, P<0.001), pulmonary artery systolic (r=0.83, P<0.001) and diastolic pressure (r=0.51, P=0.009), and mean right atrial pressure (r=0.85, P<0.001) all had significant correlations with invasively acquired measurements. Several Doppler indices had good accuracy in identifying patients with pulmonary capillary wedge pressure >15 mm Hg (area under the curve, 0.86 to 0.92). The recent American Society of Echocardiography/European Association of Echocardiography guidelines were highly accurate (sensitivity, 98%; specificity, 91%) in identifying patients with increased wedge pressure. In 12 repeat studies, Doppler echocardiography readily detected the changes in mean wedge pressure (r=0.75, P=0.005) as well as changes in pulmonary artery systolic pressure and mean right atrial pressure.
Conclusions-: Doppler echocardiography provides reliable assessment of right and left ventricular hemodynamics in patients with decompensated heart failure
Sim, toda sala de emergência merece um ecocardiografista de urgência.
