Stroke Severity and Futile Reperfusion Data from Seven Chinese Centers, 2017-2022

891 acute ischemic stroke patients from seven comprehensive stroke centers in China between 2017 and 2022 form the basis of this clinical study. The analysis focuses on the hypoperfusion intensity ratio (HIR) and its association with futile reperfusion, mediated by stroke severity measured via the NIHSS score. 35.9% of the included patients experienced futile reperfusion, defined as a poor functional outcome despite successful recanalization.

Use Cases

• Conduct causal mediation analysis based on the relationship between HIR, NIHSS score, and futile reperfusion.
• Train prognostic models for futile reperfusion risk based on perfusion imaging metrics like HIR.
• Validate the established threshold of HIR >0.4 as an indicator of poor tissue-level collaterals in a new cohort.
• Study the epidemiology of stroke treatment outcomes in a Chinese patient population from 2017 to 2022.

Strengths

• Data originates from a multi-center study across seven comprehensive stroke centers, suggesting a multi-site cohort.
• Includes 891 patient records with defined clinical outcomes (futile reperfusion observed in 320 patients).
• Analysis uses established clinical thresholds (HIR >0.4) and standardized scales (NIHSS, mRS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the underlying data files, which may limit suitability assessment.
• The 172.1 KB file size suggests the dataset is likely a summary or supplementary material, not the full raw patient-level data.
