Echocardiographic Aortic Valve Sclerosis Severity and Mortality Risk in 42,959 Patients

A clinical study dataset of 42,959 participants from an institutional echocardiographic database. It examines the graded severity of aortic valve sclerosis and its associations with systemic comorbidities, diastolic dysfunction, and mortality risk. The dataset was published by figshare admin karger and last updated in May 2026.

Use Cases

• Predicting all-cause mortality risk based on echocardiographic AVS severity and diastolic parameters.
• Analyzing associations between AVS severity and systemic comorbidities like hypertension and diabetes.
• Studying the link between aortic valve disease and heart failure with preserved ejection fraction (HFpEF).
• Investigating the relationship between AVS severity and concentric left ventricular geometry.

Strengths

• Dataset includes 42,959 participants from a large institutional database.
• AVS severity is classified into four distinct grades (Normal, Thickened, Calcified, Severely Calcified).
• Analysis includes multivariable adjustment for diastolic parameters and demonstrates a dose-dependent mortality risk.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small (45.0 KB), suggesting it contains summary or supplementary material rather than raw patient records.
• Data may reflect bias inherent to a single institutional source.

Provenance

Source

Large institutional echocardiographic database.

Collection Method

Echocardiographic study of participants; AVS severity was classified from imaging.
