Routinely-feasible multiple biomarkers score to predict prognosis after revascularized STEMI.
BACKGROUND
We assessed the long-term prognostic value of an easy-to-do multiple cardiac biomarkers score after a revascularized acute myocardial infarction (MI) in order to evaluate a multimarker approach to risk stratification, based on routine biomarkers.


METHODS
Blood samples from 138 patients hospitalized with acute myocardial infarction and successfully treated by primary coronary intervention (with TIMI 3 flow) were subsequently tested for creatinin level at admittance and then BNP, hsCRP, troponin I from Day 0 to day 7. The primary endpoint was a clinical evaluation comprising: new hospitalization for cardiac reasons, acute coronary events (acute coronary syndrome), and death.


RESULTS
During the median follow-up period of 11.01 months [9.44-12.59], 47 events were recorded. All the following markers were able to predict events: creatinemia on admission (p=0.0057), CRP on day 3 (p, troponin I on day 1 (p<0.001), BNP (p<0.0001) and biological multimarker score (p<0.0001). Clinical events were predicted with a hazard ratio (HR) of respectively 3.30 [2.88-12.30] in BNP Q4 as compared to the three lower quartiles (Q1-3), and 3.15 [2.75-21.00] for the Multimarker approach. The multimarker score was not significantly better than BNP on day 1 alone (p=0.77), troponin on day 1 alone (p=0.43), creatininemia on admission (p=0.19) or CRPhs on day 3 alone (p=0.054). Nevertheless, the Multimarker approach leads to the selection of a smaller, hence more manageable, high-risk population (13% versus 25%).


CONCLUSIONS
Among 138 subjects admitted for acute MI, and all successfully revascularized, a routinely multimarker approach with BNP, hsCRP, creatininemia, troponin I, is feasible. BNP is the most powerful marker, and this multimarker approach renders additional prognostic information helping to identify patients with high-risk to clinical events.
