Impact of percutaneous coronary intervention on biomarker levels in patients in the subacute phase following myocardial infarction: the Occluded Artery Trial (OAT) biomarker ancillary study.

Background: The purpose of the Occluded Artery Trial (OAT) Biomarker substudy was to evaluate the impact of infarct related artery (IRA) revascularization on serial levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and dynamics of other biomarkers related to left ventricular remodeling, fibrosis and angiogenesis.

Methods: Patients were eligible for OAT-Biomarker based on the main OAT criteria. Of 70 patients (age 60.

The degree of restored myocardial perfusion in acute myocardial infarction influences immediate and long-term results of primary coronary angioplasty.

Background: Tissue perfusion during acute myocardial infarction (AMI) may be assessed by means of the angiographic method -- TIMI myocardial perfusion (TMP). We hypothesised that TMP grade (TMPG) after primary coronary angioplasty (PCI) implicates immediate and long-term clinical outcomes.

Methods: We studied 588 consecutive patients (mean age 58.
