Routinely-feasible multiple biomarkers score to predict prognosis after revascularized STEMI

Area of Science:

• Cardiology
• Biomarkers
• Risk Stratification

Background:

• Assessing the long-term prognostic value of a simple multiple cardiac biomarker score after revascularized acute myocardial infarction (MI).
• Evaluating a multimarker approach for risk stratification using routine biomarkers.

Purpose of the Study:

• To determine the prognostic value of a multimarker score in patients post-revascularized acute MI.
• To assess the feasibility of a routine multimarker approach for risk stratification.

Main Methods:

• 138 patients with acute MI treated by primary coronary intervention were analyzed.
• Blood samples tested for creatininemia, BNP, hsCRP, and troponin I from admission to day 7.
• Primary endpoint: hospitalization for cardiac reasons, acute coronary events, or death.

Main Results:

• All assessed markers (creatininemia, hsCRP, troponin I, BNP) and the multimarker score predicted clinical events.
• BNP and the multimarker score showed significant hazard ratios for predicting events.
• The multimarker approach identified a smaller, manageable high-risk population (13%) compared to individual markers.

Conclusions:

• A routine multimarker approach using BNP, hsCRP, creatininemia, and troponin I is feasible in acute MI patients.
• BNP emerged as the most potent single marker.
• The multimarker strategy provides additional prognostic information for identifying high-risk patients.
