چکیده
BACKGROUND Incompleted ST segment resolution (STR) after primary percutaneous coronary intervention (PCI) is associated with worse clinical outcomes. AIM To investigate the association between plasma N-terminal pro B-type natriuretic peptide (NT-proBNP) levels on admission and STR after reperfusion, in a patient with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. METHODS After exclusion, 81 consecutive patients with STEMI (mean age: 61.3 ± 13.4 years) undergoing primary PCI were prospectively enrolled in this study. Patients were divided into two groups according to ST-segment resolution: ΣSTR < 50%, the no-reflow phenomenon positive (+) group (n = 20), and ΣSTR ≥ 50%, the no-reflow phenomenon negative (-) group (n = 61). Patients were followed up for six months. RESULTS The no-reflow phenomenon (+) group had similar baseline cardiovascular risk factors (e.g. age, sex, hypertension, diabetes mellitus) but higher mid-term mortality (25% vs. 6.5%, p = 0.02) than the no-reflow phenomenon (-) group. The frequency of anterior MI in the no-reflow phenomenon (+) group was higher (75%, p = 0.02). NT-proBNP levels on admission were higher in the no-reflow phenomenon (+) group (p = 0.001). A NT-proBNP level ≥ 563.4 pg/mL measured on admission had a 72.7% sensitivity and 72.9% specificity in predicting no-reflow phenomenon at ROC curve analysis. At multivariate analysis, anterior MI, high NT-proBNP levels, prolonged chest pain-to-reperfusion time (> 6 h) and post-TIMI-3 flow were independent predictors of no-reflow phenomenon after primary PCI. CONCLUSIONS Plasma NT-proBNP level on admission is a strong and independent predictor of no-reflow phenomenon following primary PCI and mid-term cardiovascular mortality in patients with STEMI.

Improved early risk stratification of patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention using a combination of serum soluble ST2 and NT-proBNP
BACKGROUND Although soluble suppression of tumorigenicity 2 (sST2) in serum is known to be associated with ischemic heart disease and heart failure, data regarding its prognostic impact in ST-segment elevation myocardial infarction (STEMI) is limited. We evaluated the prognostic impacts of serum sST2 and other serum biomarkers in STEMI patients undergoing primary percutaneous coronary intervent...

BACKGROUND Patients undergoing acute left main (LM) coronary artery revascularization have a high mortality and natriuretic peptides such as N-terminal pro-B-type (NT-proBNP) have been shown to have prognostic value in patients with acute coronary syndromes. The present study looked at the prognostic value of NT-proBNP in these patients. METHODS AND RESULTS We studied all consecutive patients...

BACKGROUND Cardiovascular diseases continue to be the main cause of death in the general population. Despite the fact that primary percutaneous coronary intervention (PCI) improves prognosis in patients with acute myocardial infarction (AMI), heart failure can still develop in some of these subjects. Measurement of natriuretic peptide levels has been shown to be useful in the detection of left ...
متن کاملNT-proBNP during and after primary PCI for improved scheduling of early hospital discharge
BACKGROUND The Zwolle Risk Score (ZRS) identifies primary percutaneous coronary intervention (PPCI) patients at low mortality risk, eligible for early discharge. Recently, this score was improved by adding baseline NT-proBNP. However, the optimal timepoint for NT-proBNP measurement is unknown. METHODS PPCI patients in the On-Time 2 study were candidates. The ZRS and NT-proBNP levels on admiss...
