Adenosine administration is currently required for evaluation of stenosis severity with fractional flow reserve (FFR). The instantaneous wave-free ratio (iFR) was recently introduced as an adenosine-free alternative in patients with stable CAD. The aim of the present study was to replicate the findings of previous iFR studies using an independent calculation algorithm and to evaluate the iFR for the assessment of non-culprit vessels in patients with acute coronary syndrome (ACS). ⋯ The iFR is a promising method for the assessment of non-culprit lesion severity in patients with acute coronary syndrome.

Randomized Controlled Trial Multicenter Study
Remote ischemic preconditioning reduces contrast-induced acute kidney injury in patients with ST-elevation myocardial infarction: a randomized controlled trial.
Contrast medium-induced acute kidney injury (CI-AKI) is a cardiovascular complication after myocardial infarction treated with emergency percutaneous coronary intervention. The aim of this randomized, sham-controlled trial was to evaluate the impact of remote ischemic preconditioning (RIPC) on CI-AKI in patients with ST-elevation myocardial infarction who received emergency primary percutaneous coronary intervention. ⋯ In patients with ST-elevation myocardial infarction, RIPC before percutaneous coronary intervention reduced the incidence of CI-AKI.
