Cardiogenic Shock Patient Data with Dual-Index Phenotype and 28-Day Mortality

A single-center prospective observational cohort study of 444 cardiogenic shock patients alive in the ICU at 30 hours, conducted from January 2021 to December 2025. The dataset tests associations between a dual-index phenotype (hypoalbuminemia and hyperchloremia) and 28-day in-hospital mortality. Results include adjusted odds ratios and C-statistics for model discrimination.

Use Cases

• Predicting 28-day in-hospital mortality based on the dual-index phenotype (albumin and chloride levels).
• Assessing the incremental prognostic value of adding a dual-index phenotype to a clinical landmark model.
• Analyzing patient trajectories by categorizing changes in dual-index phenotype status between ICU admission and reassessment.

Strengths

• Dataset includes 444 patients in the analytic cohort with a defined 28-day mortality rate of 18.2%.
• Association results are supported by multiple sensitivity analyses including propensity-score weighting and competing-risk modeling.
• The study design uses a prespecified 30-hour landmark to condition the analytic cohort.

Limitations

• Row count for the full dataset is unknown, limiting assessment of scale.
• Column-level documentation is absent; field semantics must be inferred after download.
• The reassessment subset is small (n=96), leading to wide uncertainty in trajectory findings as noted in the description.
