Change in -LSB- ( @ ) H -RSB- - DHPG to -LSB- ( @ ) H -RSB- - NE ratio correlated with improvements in diastolic blood pressure ( r = -@ , P = @ ) , the ratio of early ( E ) to late ( A ) peak transmitral diastolic inflow velocity ( r = @ , P = @ ) , E wave deceleration time ( r = -@ , P = @ ) , and insulin area under the curve@-@ during the oral glucose tolerance test ( r = -@ , P = @ ) .
