Impact of hyperglycemia at admission in patients with acute ST-segment elevation myocardial infarction as assessed by contrast-enhanced MRI.

Background: Blood glucose level at admission in ST-segment elevation myocardial infarction (STEMI) is a predictor of heart failure and mortality. This study was performed to investigate the impact of hyperglycemia at admission in non-diabetic patients on infarct size, microvascular obstruction, and long-term outcome using contrast-enhanced magnetic resonance imaging (CMR) in patients with acute STEMI.

Methods: One hundred and seven consecutive patients (84 males; mean age 59.

Relation of B-type natriuretic peptide (BNP) and infarct size as assessed by contrast-enhanced MRI.

Background: Plasma B-type natriuretic peptide (BNP) measured in acute coronary syndromes independently predicts mortality, myocardial infarction and congestive heart failure.

Objectives: To investigate the relationship between the extent of delayed enhancement (DE) and microvascular obstruction (MO) in contrast-enhanced MRI and the plasma level of BNP in patients with acute myocardial infarction.

Methods: The study group consisted of 41 consecutive patients (26 males, mean age 57±11 years) with a first STEMI and complete reperfusion by primary PCI.
