Prognostic impact of coronary microvascular dysfunction in patients with myocardial infarction evaluated by new angiography-derived index of microvascular resistance.

Background: Several methods for measuring IMR derived from angiography have been developed. AngioIMR is a novel method for the assessment of angiography-derived IMR with no requirement for a wire and hyperemia. The prognostic value of AngioIMR is unknown in STEMI patients.

Coronary Angiography Upgraded by Imaging Post-Processing: Present and Future Directions.

Advances in computer technology and image processing now allow us to obtain from angiographic images a large variety of information on coronary physiology without the use of a guide-wire as a diagnostic information equivalent to FFR and iFR but also information allowing for the performance of a real virtual percutaneous coronary intervention (PCI) and finally the ability to obtain information to optimize the results of PCI. With specific software, it is now possible to have a real upgrading of invasive coronary angiography. In this review, we present the different advances in this field and discuss the future perspectives offered by this technology.

[Impact of out-of-hospital presentation remote areas of patients with myocardial infarction with ST segment elevation : From the Nord-Alpin Emergency Network [RENAU]].

Background: European guidelines order management of patients with ST-segment elevation myocardial infarction (STEMI) less than 12 hours. They encourage healthcare networks to rapid coronary reperfusion strategy depending on the distance of the patient from the PCI center.

Objective: To determine impact of out-of-hospital presentation of patients with STEMI in remote areas within the framework of a care network, and to define the degree of compliance with local recommendations, and its prognostic impact.
