Microvascular Obstruction in Patients With Anterior STEMI Treated With Supersaturated Oxygen.

ABSTRACT:

Background

Supersaturated oxygen (SSO₂) delivered into the left anterior descending coronary artery after percutaneous coronary intervention (PCI) for anterior ST-segment elevation myocardial infarction (STEMI) has been shown to reduce infarct size, but its effects on microvascular obstruction (MVO) are unknown. The aim of this study was to compare MVO in patients with anterior STEMI treated with SSO₂ after successful primary PCI from 2 studies (the optimized SSO₂ pilot and IC-HOT) with similar patients from 7 randomized trials who underwent primary PCI without SSO₂ treatment.

Methods

A total of 874 patients with anterior STEMI who underwent MVO assessment using cardiac magnetic resonance imaging within 10 days after primary PCI we
