Compared with patients with lesser regression , patients with greater LVMi regression had a similar rate of all-cause mortality ( 14.1 % vs. 14.3 % , p = 0.99 ) , but a lower rate of rehospitalization ( 9.5 % vs. 18.5 % , hazard ratio [ HR ] : 0.50 , 95 % confidence interval [ CI ] : 0.32 to 0.78 ; p = 0.002 ) and a lower rate of rehospitalization specifically for heart failure ( 7.3 % vs. 13.6 % , p = 0.01 ) .
