Hypertensive donors (n=16)	0.0250 (0.0043)	0.068
Hypertensive donors without CMP (n=8)	0.0264 (0.0074)	0.101
Hypertensive donors with CMP (n=8)	0.0237 (0.0052)	0.173
Chronic alcohol consumption donors (n=23)	0.0206 (0.0042)	0.002
Chronic alcohol consumption donors without CMP (n=11)	0.0132 (0.0012)	0.000
