* Hemoglobin concentration less than 10 g/dL at the time of random allocation
* Patient physician believes that both of the transfusion strategies are consistent with good medical care for the patient

Exclusion Criteria:

* Uncontrolled acute bleeding at the time of randomization defined as the need for uncrossed or non-type specific blood
* Decline blood transfusion
* Scheduled for cardiac surgery during the current admission

B: Inclusion Criteria:

1. ≥18 and ≤65 years of age
2. Planned cardiac surgery using cardiopulmonary bypass

Exclusion Criteria:

* - Myocardial infarction and/or unstable angina in the 4 weeks prior to surgery
* Refusal to participate in the study
* Minor patient (age \< 18 years)
