Comparative StudyMethodological design for economic evaluation in Public Access Defibrillation (PAD) trial.
Our objective is to describe the rationale and methods for the economic analysis of the PAD trial. The objective of this analysis is to assess whether automated external defibrillators (AEDs) use by lay responders is good value for money. ⋯ The study will demonstrate whether defibrillation by lay responders improves outcomes at reasonable cost. If so, then the thousands of lives will be improved annually. If not, then limited resources can be invested in other interventions. Our methods also provide a framework for economic evaluations of other interventions for acute cardiovascular events.

Randomized Controlled Trial Multicenter Study Comparative StudyEffect of angiotensin-converting enzyme or vasopeptidase inhibition on ventricular size and function in patients with heart failure: the Omapatrilat Versus Enalapril Randomized Trial of Utility in Reducing Events (OVERTURE) echocardiographic study.
Angiotensin-converting enzyme (ACE) inhibition attenuates ventricular remodeling and improves ventricular function in heart failure patients. Vasopeptidase inhibition has shown similar effects in experimental models. ⋯ Ventricular size and function improved similarly after 1 year with ACE or vasopeptidase inhibition in patients with heart failure. Reverse remodeling was associated with improved outcome.

Randomized Controlled Trial Comparative StudyLeft Atrial Appendage Occlusion Study (LAAOS): results of a randomized controlled pilot study of left atrial appendage occlusion during coronary bypass surgery in patients at risk for stroke.
This pilot study assessed the safety and efficacy of left atrial appendage (LAA) occlusion, performed at the time of coronary artery bypass grafting (CABG). ⋯ LAA occlusion at the time of CABG is safe. The rate of complete occlusion improves, to acceptable levels, with increased experience and the use of a stapling device. A large trial is needed to determine if LAA occlusion prevents stroke.
