CALLY Index in PPCI Patients

Details and patient eligibility

About

This study aims to evaluate the relationship between the admission CALLY index and short-term adverse outcomes in STEMI patients undergoing PPCI. Specifically, it seeks to determine whether the CALLY index is associated with in-hospital and 30-day complications, including heart failure, arrhythmias, reinfarction, or death. Additionally, the study will assess the association between the CALLY index and procedural success, defined by post-intervention TIMI flow, as well as the complexity of coronary artery disease using the SYNTAX score.

Full description

• ST-elevation myocardial infarction (STEMI) remains a leading cause of morbidity and mortality worldwide. Early risk stratification in patients undergoing primary percutaneous coronary intervention (PPCI) is crucial to predict adverse outcomes and optimize management.
• The C-reactive protein-albumin-lymphocyte (CALLY) index is an emerging biomarker combining inflammation, nutrition, and immune status. Previous studies have demonstrated associations between the CALLY index and long-term mortality in cardiovascular disease, elderly populations, and STEMI patients . However, most of these studies focus on long-term outcomes or utilize complex predictive models (e.g., machine learning), and there is limited research assessing the direct relationship between admission CALLY index and immediate procedural outcomes, such as PPCI success or short-term adverse events., Unlike previous studies that included retrospective data, large national databases, or machine learning prediction models, this study will focus on a short-term, real-time assessment of the CALLY index at admission and its immediate association with procedural outcomes and in-hospital adverse events
