Change in [ ( 3 ) H ] - DHPG to [ ( 3 ) H ] - NE ratio correlated with improvements in diastolic blood pressure ( r = -0.67 , P = .002 ) , the ratio of early ( E ) to late ( A ) peak transmitral diastolic inflow velocity ( r = 0.62 , P = .008 ) , E wave deceleration time ( r = -0.48 , P = .05 ) , and insulin area under the curve0-120 during the oral glucose tolerance test ( r = -0.42 , P = .08 ) .
