Medical Research: What are the main findings of the study?
Dr. Estep: There were two major findings:
1-Non-invasive Doppler echocardiographic and invasive measures of mean right atrial pressure (RAP) (r = 0.863; p < 0.0001), systolic pulmonary artery pressure (sPAP) (r=0.880; p<0.0001), right ventricular outflow tract stroke volume (r=0.660; p < 0.0001), and pulmonary vascular resistance (r = 0.643; p= 0.001) correlated significantly.
2-An algorithm integrating mitral inflow velocities, RAP, sPAP, and left atrial volume index was 90% accurate in distinguishing normal from elevated left ventricular filling pressures.
