Benefits of sacubitril/valsartan use in patients with chronic heart failure after cardiac valve surgery: a single-center retrospective study

Table 4 Comparison data of inter-group differences prior and post treatment on the two patient groups

Valuables	Group A(n = 172)	Group B(n = 87)	P value
∆ SBP(mmHg)	-13.13 ± 23.98	-1.81 ± 10.89	<0.001
∆ DBP(mmHg)	-8.28 ± 17.79	-2.37 ± 11.41	0.005
∆ LVEF(%)	11.14 ± 10.16	7.15 ± 11.18	0.004
∆ LVEDD(mm)	-3.58 ± 9.21	-0.27 ± 14.44	0.026
∆ LVESD(mm)	-4.21 ± 8.15	-1.14 ± 12.12	0.016
∆ NT-ProBNP(pg/ml)	-902.0(-2226.0, -269.5)	-535.0(-1738, -7.0)	0.029

Continuous variables were present as mean ± SD or median and inter-quartile range, and the counts were expressed as a percentage.Chi-square test for categorical variables and t test or wilcoxon rank sum test for continuous variables. The following tables show the same expression
∆ : Comparison data of Valuables in final value minus initial value on the two patient groups. A decrease is expressed as a negative number while an increase is expressed as a positive number
