Official Title

Noninvasive Artificial Venous Stasis and Coronary Reperfusion in ST-Segment Elevation Myocardial Infarction:The RE-START STEMI Randomized Trial

Brief Summary

This prospective, randomized study was designed to evaluate whether the noninvasive artificial venous stasis / RE-START procedure, administered prior to primary percutaneous coronary intervention, increases the frequency of spontaneous coronary reperfusion in the infarct-related artery.

Detailed Description

The primary hypothesis of the study is that the application of short-term, controlled venous return restriction via a blood pressure cuff on the non-dominant arm may support thrombus lysis by stimulating endothelial-derived fibrinolytic activity and may increase the rate of spontaneous reperfusion, defined as TIMI 2 or TIMI 3 flow, in the infarct-related artery prior to primary percutaneous coronary intervention.

This study seeks to answer the following key question: In patients with acute STEMI, does the RE-START procedure-administered without delaying standard care or the preparation process for primary percutaneous coronary intervention-increase the incidence of spontaneous coronary reperfusion prior to primary percutaneous coronary intervention compared to a sham/control procedure?
