Association between time and severe hypoperfusion with risk of hemorrhagic transformation in stroke patients.

ABSTRACT:

Introduction

Perfusion imaging studies show a substantially increased risk of hemorrhagic transformation (HT) in severely hypoperfused tissue. Preclinical evidence indicates that ischemic damage is influenced not only by the degree of hypoperfusion but also by the duration of exposure to that hypoperfused state. We aim to investigate the association of time and severe hypoperfusion with parenchymal hematoma (PH) in ischemic stroke and explore whether there is a combined effect of the two variables on PH.

Methods

Data are from the ESCAPE-NA1 trial, which evaluated the effect of nerinetide in large vessel occlusion patients treated with thrombectomy. This study included patients with some degree of recanalization (expanded Thrombolysis in Cerebral Infarct [eTICI] > 0) and avai
