Prognostic Value of CTI for MACE in STEMI Patients After PCI

618 STEMI patients who underwent PCI were retrospectively enrolled to evaluate the prognostic value of the CTI metric. The dataset, authored by Qiang Zhao and last updated in May 2026, was used to assess the association between CTI and 1-year major adverse cardiovascular events. During follow-up, 139 patients (22.5%) experienced MACE.

Use Cases

• Predicting 1-year major adverse cardiovascular events based on CTI and other clinical features.
• Evaluating the incremental prognostic value of CTI using time-dependent ROC curve analysis.
• Assessing the association between CTI and specific event types like acute heart failure.
• Conducting subgroup analysis to test the consistency of CTI's predictive power in diabetic vs. non-diabetic patients.

Strengths

• Includes data from 618 patient records, providing a substantive cohort for analysis.
• Study design involved multiple validation methods, including Boruta feature selection, Cox regression, and sensitivity analyses.
• Clear primary endpoint defined as 1-year MACE with 139 observed events (22.5%).

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Data is contained in a 19.6 KB DOCX file, suggesting the shared data may be summary tables rather than the full patient-level dataset.
• The retrospective, single-study nature may introduce selection bias not described in the metadata.
