A Proposed Clinical Validation Pathway for the Artificial Intelligence-Driven Integrated Risk Assessment of Cardiovascular Disease (AIRA-CVD): A Translational Framework Integrating Inflammatory Biomarkers, Histopathology, and Machine Learning.

Cardiovascular disease (CVD) remains a leading cause of morbidity, mortality, and healthcare expenditure despite advances in prevention and treatment. The Artificial Intelligence-Driven Integrated Risk Assessment of Cardiovascular Disease (AIRA-CVD) framework was proposed as a multimodal architecture integrating clinical data, inflammatory biomarkers, imaging findings, and histopathological evidence of vascular remodeling to support precision cardiovascular risk assessment. This technical report presents a structured clinical validation pathway designed to facilitate future implementation and evaluation of the framework. The proposed pathway consists of four sequential phases: retrospective electronic health record analysis, inflammatory biomarker integration, histopathological validation, and prospective clinical implementation. The framework further incorporates a hybrid machine learning architecture, explainable artificial intelligence methodologies, human-in-the-loop clinical oversight, and algorithmic fairness considerations to support transparency, interpretability, and responsible deployment. Potential applications include enhanced cardiovascular risk stratification, earlier identification of high-risk individuals, support for preventive interventions, and integration within clinical decision-support and population health management systems. By providing a translational roadmap for validation and implementation, this report seeks to bridge the gap between computational innovation and patient-centered cardiovascular care while advancing the development of biologically informed artificial intelligence systems in cardiovascular medicine.
