Nitrous oxide/oxygen plus acetaminophen versus morphine in ST elevation myocardial infarction: open-label, cluster-randomized, non-inferiority study.

Background: Studies have shown disparate results on the consequences of morphine use in ST-segment elevation myocardial infarction (STEMI). No study has evaluated alternative treatments that could be at least non-inferior to morphine without its potentially damaging consequences for myocardial function and platelet reactivity. The aim of this study was to evaluate whether nitrous oxide/oxygen plus intravenous acetaminophen (NOO-A) is non-inferior to morphine to control chest pain in STEMI patients.

Benefit of immediate coronary angiography after out-of-hospital cardiac arrest in France: A nationwide propensity score analysis from the RéAC Registry.

Background: The survival rate of out-of-hospital cardiac arrest (OHCA) remains extremely low, generally under 10%. Post-resuscitation care, and particularly early coronary reperfusion, may improve this outcome. The main objective of the present study was to determine whether patients with immediate coronary angiography at hospital admission (CAA) had a better outcome than patients without immediate CAA.

Short and long-term outcomes of alcohol septal ablation with the trans-radial versus the trans-femoral approach: A single center-experience.

Background: Although the trans-radial approach (TR) has been applied to various subsets of patients in percutaneous coronary intervention, the feasibility, efficacy, acute procedural and long-term outcomes of TR versus trans-femoral approach (TF) for alcohol septal ablation (ASA) have not yet been determined.

Objectives: The aim of this study was to compare the short and long-term outcomes of ASA with the TR approach compared to the TF approach.

Methods: We retrospectively analyzed 240 patients who underwent an ASA procedure at our institution from November 1999 to November 2015.
