This article introduces CardioVascBench, a new benchmark for evaluating AI models in generating prioritized cardiovascular diagnoses from real-world clinical records. The study demonstrates that high accuracy in identifying primary diagnoses does not guarantee better overall list precision, highlighting the need for specialized evaluation metrics beyond standard classification scores. Additionally, it presents CardioKG-Agent, a knowledge-enhanced baseline that significantly outperforms supervised fine-tuning alone by integrating entity normalization and guideline evidence.
CardioVascBench:Prioritized Diagnosis Generation from Real-World Chinese Cardiovascular Records
arXiv:2611.04687v1 Announce Type: new Abstract: Identifying the primary diagnosis alone does not fully characterize a model's diagnosis-generation performance. We introduce CardioVascBench, a retrospective benchmark for prioritized diagnosis generation from real-world Chinese cardiovascular inpatient records. It contains 3,262 de-identified cases, with 2,174 for training and 1,088 for evaluation, linking clinical narratives and textual ECG reports to expert-verified, ordered discharge diagnoses standardized to ICD-10. An English translation of the evaluation set supports aligned cross-lingual comparison. Our evaluation protocol combines terminology normalization and rank-aware scoring to separately assess primary-diagnosis identification, reference-diagnosis coverage, and list precision. Evaluation across 36 systems shows that higher primary-diagnosis accuracy does not necessarily imply higher list precision against discharge references. We also provide CardioKG-Agent, a knowledge-enhanced baseline combining entity normalization, constrained graph retrieval, and guideline evidence. In a staged comparison of three baseline models, supervised fine-tuning plus the agent achieves a 73.5% higher mean composite score than fine-tuning alone, representing a system-level gain. These results measure retrospective agreement with recorded diagnoses; agreement between metric rankings and physician judgments remains to be validated. CardioVascBench supports research on diagnosis prioritization and knowledge-enhanced generation.
