Inotropes were frequently used in both the < @ mm Hg ( @/@ -LSB- @ % -RSB- ) and the @ mm Hg ( @/@ -LSB- @ % -RSB- ) SBP subgroups and were associated with higher risk for major events in both subgroups ( adjusted hazard ratio -LSB- HR -RSB- @ , @ % confidence interval -LSB- CI -RSB- @-@ @ -LSB- P < @ -RSB- ; and HR @ , @ % CI @-@ @ -LSB- P = @ -RSB- ; respectively ) .
