<p>The population data.</p>

A dataset of 604 patients with 733 coronary lesions, created by Abdulrahman AlQazzaz, investigating the association between red blood cell parameters and angiography-derived index of microcirculatory resistance (angio-IMR). The data was last updated on March 25, 2026, and is available in XLSX format under a CC-BY-4.0 license.

Use Cases

• Training predictive models for microcirculatory resistance based on red blood cell (RBC) parameters like Hct and Hgb.
• Conducting subgroup analyses on cardiovascular outcomes based on diabetes status and affected coronary vessel (LAD, LCx, RCA).
• Validating clinical biomarkers for coronary microvascular dysfunction using multivariable linear regression models.

Strengths

• Dataset includes 604 patients and 733 coronary lesions, providing a specific clinical cohort.
• Analysis includes subgroup stratification by diabetes status and coronary vessel, allowing for detailed effect modification studies.
• Results were validated through sensitivity analyses excluding hematocrit outliers.

Limitations

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