Objective:

To assess whether pre-procedural left ventricular ejection fraction (LVEF) is associated with outcomes after percutaneous coronary intervention (PCI) in heart transplant recipients.

Approach:

• Design and population: Retrospective single-center analysis of adult heart transplant recipients who underwent PCI from January 2011 through June 2023; each patient was included once, at their first PCI.
• Groups and follow-up: Patients were grouped by pre-PCI LVEF as preserved (>50%) or reduced (≤50%). Outcomes were assessed during hospitalization and through a maximum of three years.
• Outcomes and analysis: The primary endpoint was all-cause mortality. Secondary endpoints included mortality and MACCE, defined as death, myocardial infarction, stroke, or target-vessel/target-lesion revascularization. Multivariable analyses adjusted for age, eGFR, hemoglobin, BMI, r…

Key Findings:

• The cohort included 159 recipients: 107 (67.3%) had LVEF >50% and 52 (32.7%) had LVEF ≤50%.
• Recipients with LVEF ≤50% were younger on average than those with LVEF >50% (54.13 ± 15.65 vs 59.34 ± 14.98 years).
• The provided article context ends before reporting clinical outcome results; associations between LVEF and mortality or MACCE are therefore not available.

Interpretation:

The supplied context describes the study design and initial baseline findings but does not provide results sufficient to determine how LVEF related to post-PCI outcomes.

Limitations:

• The supplied context is incomplete and does not include the full results or discussion.
• The study was a retrospective analysis from a single center.
