Periprocedural Assessment of Coronary Microcirculatory Function to Predict Clinical Outcomes After Elective Percutaneous Coronary Intervention.

ABSTRACT:

Background

Percutaneous coronary intervention (PCI) could restore epicardial blood flow through the stent-based angioplasty. However, coronary microcirculatory function also affects clinical outcomes and can be quantified by the angiography-derived index of microcirculatory resistance (angio-IMR). The prognostic significance of periprocedural angio-IMR in patients undergoing elective PCI remains unclear. This study aimed to assess angio-IMR before and after PCI, as well as their association with long-term prognosis.

Methods

Data from 1768 patients with stable coronary artery disease undergoing elective PCI were analyzed. The primary end point was major adverse cardiac events (MACE) comprising death and nonfatal myocardial infarction.

Results

The median angio-IMR was 1
