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.

[Principles of optimal preparation of material from bronchoalveolar lavage (BAL)for cytoimmunologic examinations in interstitial lung diseases ].

In this paper we considered the value of correctly performed bronchoalveolar lavage (BAL) in diagnosis of interstitial lung diseases and in assessment of the activity of pathological process. We indicated the conditions of exact interpretation of the results of BAL cytoimmunological examination, i.e.

[Cytoimmunologic changes in material obtained from bronchoalveolar lavage (BAL) in asymptomatic individuals chronically exposed to silica dust].

The aim of this study was to determine and to evaluate silica induced lung cell reactivity--if any--in bronchoalveolar space, before clinical changes develop. Bronchoalveolar lavage (BAL) was carried out in 15 nonsmoking individuals with chronic professional silica exposure, free of lung signs and symptoms. Controls were healthy nonsmokers.
