Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

MIRON-CCS is a multicenter retrospective diagnostic study designed to evaluate the role of high-sensitivity cardiac troponin I (hs-cTnI) in the diagnosis and clinical stage classification of acute myocardial infarction (AMI) as defined by the Canadian Cardiovascular Society (CCS) AMI staging system.

The study retrospectively analyzes biomarker data from patients diagnosed with AMI across multiple institutions, focusing on whether hs-cTnI levels-measured at specific time points-can reliably identify and stratify patients into CCS-defined AMI clinical stages (Stage 1 to Stage 4). It aims to correlate hs-cTnI kinetics and peak levels with clinical stage, presentation patterns, and outcomes.

This trial seeks to offer a biomarker-based alternative to imaging-heavy staging, potentially streamlining early diagnosis and therapeutic triage for AMI patients in varied clinical settings.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Index STEMI with Primary PCI with Stenting

The study population consists of individuals aged 18 to 80 who have been diagnosed with acute ST-elevation myocardial infarction (STEMI) and are scheduled for emergency percutaneous coronary intervention (PCI).

No interventions assigned to this group
