Long-term survival after successful inhospital cardiac arrest resuscitation.
Little is known about long-term outcomes of patients who survive inhospital cardiac arrest. ⋯ Subjects with inhospital cardiac arrest have poor long-term prognoses. A strategy that improved inhospital survival did not alter long-term mortality rate. Thus, survival to discharge may not be a sufficient end point for future resuscitation trials.

Multicenter Study Comparative StudyExercise oscillatory breathing and increased ventilation to carbon dioxide production slope in heart failure: an unfavorable combination with high prognostic value.
Increased slope of exercise ventilation to carbon dioxide production (VE/VCO2) is an established prognosticator in patients with heart failure. Recently, the occurrence of exercise oscillatory breathing (EOB) has emerged as an additional strong indicator of survival. ⋯ These findings identify EOB as a strong survival predictor even more powerful than VE/VCO2 slope. Exercise oscillatory breathing presence does not necessarily imply an elevated VE/VCO2 slope, but combination of either both yields to a burden of risk remarkably high.

Randomized Controlled Trial Comparative StudyEarly invasive versus conservative treatment in patients with failed fibrinolysis--no late survival benefit: the final analysis of the Middlesbrough Early Revascularisation to Limit Infarction (MERLIN) randomized trial.
Early (30 days) and midterm (6 months) clinical outcomes in trials comparing rescue angioplasty (rescue percutaneous coronary intervention [rPCI]) with conservative treatment of failed fibrinolysis complicating ST-segment elevation myocardial infarction have shown variable results. Whether early rPCI confers late (up to 3 years) clinical benefits is not known. ⋯ Rescue angioplasty did not confer a late survival advantage at 3 years. The composite end point occurred less often in the rPCI arm mainly because of fewer unplanned revascularization procedures in the early phase of follow-up. The highest risk of clinical events in patients with failed reperfusion is in the first year, beyond which the rate of clinical events is low.

Comparative StudyOutcome after out-of-hospital cardiac arrest in a physician-staffed emergency medical system according to the Utstein style.
Despite a large amount of data assessing outcomes of out-of-hospital cardiac arrests (OHCAs), little information is available about physician-staffed emergency medical service (EMS) systems. The aim of our study was to investigate the impact of a physician on the outcome of patients after OHCA. ⋯ A physician on board of the advanced life support unit was not identified as an independent factor of improved survival.

Comparative StudyDetection of pulmonary vein stenosis by transesophageal echocardiography: comparison with multidetector computed tomography.
The objective of this study is to compare the use of transesophageal echocardiography (TEE) vs multidetector computed tomography (MDCT) for detecting pulmonary vein stenosis. ⋯ Transesophageal echocardiography was able to detect most pulmonary veins with good sensitivity and specificity in comparison to MDCT. Pulmonary veins may be visualized more frequently by MDCT; however, TEE provides additional data about the functional significance of a pulmonary vein stenosis.
