Coronary Microvascular Dysfunction and In-Hospital Outcomes in 1,027 STEMI Patients

A clinical study dataset of 1,027 ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). The data compares in-hospital major adverse cardiovascular events (MACE) and post-procedural coronary angiography–derived index of microcirculatory resistance (caIMR) between patients with and without standard modifiable cardiovascular risk factors. The dataset was authored by Guoli Yao and last updated on 2026-04-17.

Use Cases

• Assessing the mediating role of coronary microvascular dysfunction (CMVD) based on post-procedural caIMR values.
• Comparing in-hospital MACE incidence between patient groups with and without standard modifiable risk factors.
• Performing mediation analysis to understand pathways linking risk factor status to adverse outcomes.
• Investigating the predictive value of quantitative coronary angiography-derived indices for clinical events.

Strengths

• Includes data from 1,027 STEMI patients, providing a substantial clinical cohort.
• Reports specific incidence rates for in-hospital MACE (15.3% vs. 7.0%).
• Contains a quantitative surrogate measure for coronary microvascular dysfunction (caIMR).

Limitations

• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 45.5 KB file size suggests a limited scope, likely containing summary results rather than raw patient-level data.
