After adjustment for these variables , left ventricular structure ( diastolic dimension [ 1.5 % , P = 0.008 ] and left ventricular mass [ 1.6 % , P = 0.008 ] ) , resting stroke volume ( 2.0 % , P = 0.002 ) , left ventricular diastolic dysfunction ( deceleration time [ 0.9 % , P = 0.03 ] and E/e ' [ 1.4 % , P = 0.009 ] ) , and arterial function ( arterial elastance [ 2.1 % , P = 0.002 ] and systemic arterial compliance [ 1.5 % , P = 0.007 ] ) , each explained only a small additional portion of the variance in peak oxygen consumption .
