we measured total blood volume ( 125i-albumin ) , cardiac dimensions and function ( echocardiography with doppler ) , systemic hemodynamics ( blood pressure and pulse ) , and plasma renin activity and norepinephrine levels in cirrhotic patients with and without ascites to assess the likelihood that either diminished central or arterial filling is the stimulus to sodium retention .
