Please select the eligibility criteria that correspond to the clinical trial below.
Title: Myocardial Ischemia and Transfusion Pilot
Brief Summary: The purpose of this study is to evaluate two approaches to red blood cell transfusion in anemic patients with acute coronary syndrome.


Options:
A: Inclusion Criteria:

* age 18 or older;
* STEMI (ST segment elevated myocardial infarction)
* NSTEMI (Non ST segment elevation myocardial infarction)
* unstable angina
* stable coronary artery disease (undergoing cardiac catheterization during the index hospitalization);
* written informed consent has been obtained
* hemoglobin concentration less than 10 g/dL at the time of random allocation.

Exclusion Criteria:

* bleeding cannot be controlled at the cardiac catheterization puncture site and/or require surgery to repair vessel
* retroperitoneal bleeding requiring surgery
* clinically important hemodynamic instability based on the judgment of the treating physician
* terminal malignancy or life expectancy less than 6 months
* scheduled for cardiac surgery within the next 30 days
* symptomatic at the time of randomization
* declines blood transfusion
* history of a clinically significant transfusion reaction
* inability to provide informed consent;
* enrolled in a competing study
* previous participation in the MINT trial
* any patient who in the judgment of the research team should not be enrolled in the trial. This would include, but not be limited to, factors such alcohol or drug dependence, or psychiatric illness.
B: Inclusion Criteria:

* Patient requiring surgery for an isolated hip fracture of less than 48 hours

Exclusion Criteria:

* Contraindication to tranexamic acid
* Contraindication to fondaparinux
* Contraindication to general anesthesia associated with a femoral nerve block
* pregnancy
C: Inclusion Criteria:

* All patients with acute upper GI hemorrhage who do not have any criterion of exclusion.

Exclusion Criteria:

* \< 18 years old.
* Pregnancy.
* Negative of the patient to receive transfusions.
* Negative of the patient to participate in the study.
* Patients with therapeutic restrictions (as terminally ill patients).
* Previous recent surgery requiring transfusion.
* Recent (less than 90 days) or unstable acute myocardic ischemia. Peripheral vasculopathy with secondary.
* To have been included in this same study in the 30 previous days.
D: Inclusion Criteria:

* Has undergone surgical repair for a hip fracture
* Has a postoperative Hgb level below 10 g/dL within three days of surgery
* Diagnosis of cardiovascular disease (e.g., coronary artery disease, congestive heart failure, stroke or transient ischemic attack, or peripheral vascular disease) or cardiovascular risk factors (e.g., diabetes mellitus, hypertension, hypercholesterolemia, tobacco use, or creatinine levels greater than 2.0 mg/dL)

Exclusion Criteria:

* Unable to walk prior to hip fracture
* Declines blood transfusions
* Suffered multiple traumas
* Pathologic fracture of the hip due to malignancy
* Clinically recognized acute myocardial infarction within the 30 days prior to study entry
* Previously participated in the trial and fractured the other hip
* Symptoms associated with anemia (e.g., ischemic chest pain) or actively bleeding at the time of randomization

Answer: A
