Resource Limits Demand Smart Triage
Patients with non-ST elevation acute coronary syndrome face high risks when left main or three-vessel disease exists. These cases need fast revascularization to cut poor outcomes. Healthcare systems face growing limits on resources though. Doctors must triage patients wisely to avoid treatment delays. A study published in the Journal of American College of Cardiology builds a simple score from first-exam findings.
Registries Give Real-World Data
Researchers pulled retrospective data from National Cardiovascular Data Registries across three hospital cohorts. They studied 1706 patients presenting with NSTE-ACS carefully. Logistic regression in the first cohort picked predictors of left main or three-vessel disease. The model then tested in the other two cohorts for validation.
Seven Simple Predictors Build Score
Among all 1706 patients, 24% had left main or three-vessel disease confirmed. Seven easy-to-check factors created the MADISON score. These included age ≥65 years, male sex, diabetes history, ECG changes, heart rate >90 bpm, past stroke or TIA, and heart failure signs. The model achieved AUC-ROC of 0.67 across all cohorts consistently.
High Score Means High Specificity
At the planned cutoff of score ≥4, MADISON showed high specificity from 83.5% to 95% for detecting left main or three-vessel disease. Sensitivity ranged lower from 3.5% to 34.4% across cohorts. This means few false positives but some high-risk cases get missed.
Triage Tool Fits Tight Systems
A high MADISON score reliably spots patients needing priority catheterization. Resource-poor settings gain most from this bedside tool.
