Periprocedural myocardial injury according to optical characteristics of neointima and treatment modality of in-stent restenosis.

ABSTRACT:

Aims

Aim of the present study was to investigate the impact of increasing neointimal inhomogeneity and neoatherosclerosis as well as of treatment modality of in-stent restenosis (ISR) on the occurrence of periprocedural myocardial injury (PMI).

Methods and results

Patients with normal or stable/falling increased baseline high-sensitivity troponin T (hs-cTnT) undergoing intravascular optical coherence tomography (OCT) and subsequent percutaneous coronary intervention (PCI) of ISR by means of drug-coated balloon (DCB) or drug-eluting stent (DES) were included. Overall, 128 patients were subdivided into low (n = 64) and high (n = 64) inhomogeneity groups, based on the median of distribution of non-homogeneous quadrants. No significant between-group differences were detected in
