Levels and comparisons of ACE, ACE2, ACE/ACE2, Ang II and Ang-(1–7) in the HD patients with CVD and without CVD.

	HD with CVD (n = 119)	HD without CVD (n = 241)
ACE (RFU/μL/h)	145 ± 38	127 ± 40***
ACE2 (RFU/μL/h)	7.0 ± 1.5	9.9 ± 2.5***
ACE/ACE2	21.5 ± 6.3	13.2 ± 4.0***
Ang II (ng/mL)	121 ± 33	98 ± 27***
Ang–(1–7) (ng/mL)	13.8 ± 4.3	15.6 ± 4.7***

Data were expressed as mean ± SD.

^***indicates p < .001 compared with the HD with CVD group.

ACE: angiotensin converting enzyme; ACE2: angiotensin converting enzyme; Ang II: angiotensin II; Ang-(1–7): angiotensin 1–7; CVD: cardiovascular diseases; HD: hemodialysis.
