ACE Intron 16 I/D polymorphism and blood loss after open heart surgery. Relationship between ACE Intron 16 I/D polymorphism and accumulated postoperative blood loss after cardiac surgery with cardiopulmonary bypass. Data presented as the mean ± standard error of the mean. ACE, Angiotensin Converting Enzyme; I, insertion; D, deletion; mL, milliliters; h, hours. # P < 0.05 between 4 h blood loss associated with ACE Intron 16 of genotypes I/I and D/D; ‡ P < 0.05 between 4 h blood loss associated with ACE Intron 16 of genotypes I/I and I/D
