Abstract

OBJECTIVES:

To analyze the prognostic value of myeloperoxidase (MPO) in relation to in-hospital mortality and to identify the optimum time point for sampling in patients with the first anterior ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (pPCI).

DESIGN AND METHODS:

A total of 100 consecutive patients with the first anterior STEMI undergoing pPCI were included. Blood samples were collected at baseline, 4, 8, 12, 18, 24, 48 and 168 hours (h) after pPCI.

RESULTS:

MPO concentrations have showed a biphasic pattern over time; the highest MPO levels were at4h and 24h after pPCI. In-hospital mortality was 6%. MPO at 24h significantly correlated with troponin I as well as heart failure. After multivariate adjustment, MPO at 24h was an independent predictor of the in-hospital mortality (OR 3.34, 95% CI 1.13-9.86, P=0.029).

CONCLUSIONS:

In patients with the first anterior STEMI treated by pPCI, MPO at 24h after procedure was an independent predictor of the in-hospital mortality.
