Duration of red cell storage before transfusion and in-hospital mortality.
Red cell transfusions are lifesaving in severely anemic or acutely bleeding patients but may be associated with an increased risk of cardiovascular events in critically ill patients. The objective of the study was to examine the association between duration of pretransfusion storage of red cells and in-hospital mortality. ⋯ In hospitalized patients with a major diagnosis of cardiovascular disease, there is a modest independent association between increasing duration of storage of red cells and risk of in-hospital mortality that appears to be continuous and graded.

Comparative StudyCardiac arrest outside and inside hospital in a community: mechanisms behind the differences in outcome and outcome in relation to time of arrest.
The aim was to compare characteristics and outcome after cardiac arrest where cardiopulmonary resuscitation was attempted outside and inside hospital over 12 years. ⋯ Compared with OHCA, the survival of patients with IHCA increased 3-fold for shockable rhythm and 7-fold for nonshockable rhythm in our practice setting. If patients were found in a shockable rhythm, the higher survival after IHCA was only partly explained by a shorter treatment delay. The time and day of CA were associated with survival in IHCA but not OHCA.

Randomized Controlled Trial Multicenter StudyIntracoronary compared with intravenous bolus abciximab application during primary percutaneous coronary intervention: design and rationale of the Abciximab Intracoronary versus intravenously Drug Application in ST-Elevation Myocardial Infarction (AIDA STEMI) trial.
Intravenous abciximab reduces major adverse cardiac events in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Intracoronary abciximab bolus application during PCI results in high local drug concentration, improved perfusion, reduction of infarct size, and less microvascular obstruction. The hypothesis of this trial is that abciximab bolus intracoronary in comparison to standard intravenous application will improve the outcome of patients undergoing primary PCI in STEMI. ⋯ The AIDA STEMI study addresses important questions regarding the efficacy and safety of intracoronary abciximab bolus administration during primary PCI in patients with STEMI, potentially optimizing the route of administration of glycoprotein IIb/IIIa inhibitors in the catheterization laboratory.

Randomized Controlled TrialDesign and methods of the Pro-B Type Natriuretic Peptide Outpatient Tailored Chronic Heart Failure Therapy (PROTECT) Study.
Serial measurements of N-terminal pro-B type natriuretic peptide (NT-proBNP) provide prognostic information in patients with chronic heart failure (HF). Changes in NT-proBNP concentrations parallel prognosis; however, it remains unclear whether HF care with a goal to maximize medical therapy and also lower NT-proBNP concentrations is superior to standard HF care alone. ⋯ The Pro-B Type Natriuretic Peptide Outpatient Tailored Chronic Heart Failure Therapy (PROTECT) Study will test the hypothesis that therapy guided by NT-proBNP concentrations will be superior to standard of care HF management (www.clinicaltrials.gov identifier NCT00351390).
