Randomized Controlled Trial Multicenter Study Comparative Study
Air Versus Oxygen in ST-Segment-Elevation Myocardial Infarction.
Oxygen is commonly administered to patients with ST-elevation-myocardial infarction despite previous studies suggesting a possible increase in myocardial injury as a result of coronary vasoconstriction and heightened oxidative stress. ⋯ URL: http://www.clinicaltrials.gov.

Randomized Controlled Trial Comparative Study
Propensity-matched comparisons of clinical outcomes after transapical or transfemoral transcatheter aortic valve replacement: a placement of aortic transcatheter valves (PARTNER)-I trial substudy.
The higher risk of adverse outcomes after transapical (TA) versus transfemoral (TF) transcatheter aortic valve replacement (TAVR) could be attributable to TA-TAVR being an open surgical procedure or to clinical differences between TA- and TF-TAVR patients. We compared outcomes after neutralizing patient differences using propensity score matching. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT00530894.
