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.
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.
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.
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.
In Vitro Effects of Poly-N-Acetyl Glucosamine on the Activation of Platelets in Platelet-Rich Plasma With and Without Red Blood Cells
Poly-N-acetyl glucosamine slurry activates platelets.
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.

Effect of Aprotinin on Clinical Outcomes in Coronary Artery Bypass Graft Surgery
OBJECTIVE: Despite proven blood transfusion benefits, aprotinin may be underused in coronary artery bypass grafting. Reluctance to use aprotinin may stem from […]
Aortic Valve Replacement With the Jostra MECC System Versus Standard Cardiopulmonary Bypass: A Randomized Prospective Trial
BACKGROUND: We prospectively evaluated a newly introduced minimal extracorporeal circulation system (Jostra MECC System; Jostra AG, Hirrlingen, Germany) for aortic valve surgery. […]
