Abstract
Objectives The predictive value of preoperative hemoglobin (HB) level on the outcome of patients undergoing valve surgery is not well established. This study evaluated the predictive value of preoperative HB level on survival after aortic valve replacement (AVR). Design This was a retrospective analysis of prospectively collected data. Setting A single-center study performed in an educational hospital. Participants All consecutive patients (n = 1,808) who underwent AVR between January 1998 and December 2010. Interventions AVR. Measurements and Main Results Patients were classified into 4 groups according to the preoperative HB level: very low (HB of 30 days) was 26.1% in the very-low-HB group, 23.7% in the low-HB group, 17.1% in the normal-HB group, and 12.6% in the high-normal-HB group (p Conclusions In patients undergoing AVR, preoperative low-HB level is an independent risk factor for late mortality, but not for early mortality.
