IBD Patient Cardiovascular Risk with CAC Progression from Chest CT Scans

A multicenter retrospective cohort of 467 inflammatory bowel disease patients without known atherosclerotic cardiovascular disease. The dataset includes results from at least two routine non-contrast chest CT scans per patient, with a mean interval of 21.2 months, tracking coronary artery calcium progression and major adverse cardiovascular events over a median follow-up of 37 months. It was authored by Qi Zhang and shared on figshare under a CC-BY-4.0 license.

Use Cases

• Predicting major adverse cardiovascular events (MACE) based on coronary artery calcium (CAC) progression patterns.
• Assessing the incremental prognostic value of CAC progression over baseline CAC and conventional risk factors.
• Investigating the association between CAC progression and incident atrial fibrillation in a specific patient population.
• Validating opportunistic use of routine chest CT scans for cardiovascular risk stratification.

Strengths

• Includes data from 467 patients across multiple medical centers, suggesting a multi-institutional perspective.
• Tracks longitudinal data with a median follow-up of 37 months and a mean scan interval of 21.2 months.
• Reports specific hazard ratios (e.g., HR 7.41 for MACE) and model performance metrics (e.g., C-index improvement from 0.67 to 0.73).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect temporal or source bias inherent to the retrospective, multicenter study design.
