Hypotensive Transfusion Reactions Can Occur With Blood Products That Are Leukoreduced Before Storage
Hypotensive reactions can occur with blood products that are LR before storage and non-LR ANH. An inherent defect in the metabolism of kinins may be a risk factor for the development of hypotensive transfusion reactions.
Advantages of Off-Pump Coronary Artery Bypass Grafting in Long-Term Hemodialysis Patients: Multicenter Analysis
OPCAB significantly decreased blood loss, blood transfusion, ICU stay, and major perioperative morbidity compared with the values for CCAB. OPCAB may have advantages over CCAB in long-term hemodialysis patients.

Can Extra Protamine Eliminate Heparin Rebound Following Cardiopulmonary Bypass Surgery
Postoperative protamine infusion was able to almost totally abolish heparin rebound. In the context of this study, protamine infusion resulted in reduced postoperative bleeding but the magnitude was insufficient to alter transfusion requirements.
Optimizing Intraoperative Cerebral Oxygen Delivery Using Noninvasive Cerebral Oximetry Decreases the Incidence of Stroke for Cardiac Surgical Patients
The treatment group, which underwent all cardiac surgeries with optimized cerebral oxygen delivery using cerebral oximetry monitoring, demonstrated a signifi- cantly lower incidence of permanent stroke. Because our study is retrospective, a prospective randomized trial is warranted.
Effect of Older Donor Age on Risk for Mortality After Heart Transplantation
Donor age as a continuous variable, however, was determined to be a notable predictor of survival and use of the donor age cut-point of 40 years (categorical variable) allowed risk stratification with similar accuracy. The use of a donor age cut-point of 40 years may be a useful clinical criterion for graft-related risk assessment.
Platelet Function Predicts Myocardial Damage in Patients With Acute Myocardial Infarction
Patients with STEMI have significantly enhanced platelet function when measured under high shear rates. CADP-CT is an independent predictor of the severity of MI, as measured by markers of cardiac necrosis. Measurement of platelet function with the PFA-100 may help in the risk stratification of patients presenting with MI.
Effects of Low Temperature on Shear-Induced Platelet Aggregation and Activation
We found that platelets are hyper-reactive to fluid shear stress at temperatures of 24, 32, and 35 degrees C as compared with at 37 degrees C. The hyperreactivity results in heightened aggregation through a platelet-activation independent mechanism.
Surgery for Aneurysms of the Aortic Root: A 30-Year Experience
Aortic root replacement for aortic root aneurysms can be done with low morbidity and mortality. Composite valve conduit reconstruction resulted in a durable result. There were few serious complications related to the need for long-term anticoagulation or a prosthetic valve.
Out-Patients Treated With Nesiritide Show Reduced Cardio Remodeling, Significant Improvements in Heart Function
Left ventricular remodeling and mitral and tricuspid regurgitation frequently follow myocardial injury, and are associated with worsening symptoms following heart failure.
