Data Sheet 1_Low admission pulse pressure and increased in-hospital mortality in patients

A retrospective analysis of 21,768 patients with heart failure admitted to the First Affiliated Hospital of Xinjiang Medical University between March 2012 and September 2023. The dataset, shared by Liying Zhong, was used to investigate the association between low admission pulse pressure and increased risk of in-hospital mortality.

Use Cases

• Predicting in-hospital mortality risk based on admission pulse pressure and other clinical covariates.
• Analyzing dose-response relationships between pulse pressure and cardiac death using restricted cubic spline models.
• Stratifying mortality risk analysis across different left-ventricular ejection fraction (LVEF) phenotypes.
• Training logistic regression models to quantify odds ratios for all-cause and cardiac mortality.

Strengths

• Includes data from 21,768 patients, providing a substantial sample size.
• Covers a long time range from March 2012 to September 2023.
• Analysis adjusted for 16 covariates, suggesting a detailed multivariable approach.
• Specific mortality outcomes are quantified with odds ratios and confidence intervals (e.g., OR 1.31 for all-cause mortality).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data is unknown, which may limit suitability assessment.
• Data originates from a single hospital, which may limit generalizability.
