OBJECTIVE The object of our study was to identify the most useful predictor of patient prognosis in acute myocardial infarction (AMI), from 7 acute-phase cardiovascular peptides which take part in neurohumoral activation [brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), renin, aldosterone, adrenomedullin, epinephrine and norepinephrine].(More)
BACKGROUND The relationship between plasma levels of serum amyloid A protein (SAA) concentrations and clinical course (including mortality) was investigated in patients with acute myocardial infarction (AMI). METHODS AND RESULTS The study enrolled 280 consecutive AMI patients who were admitted within 10 h of onset and were successfully reperfused by(More)
BACKGROUND Although cardiogenic shock (CS) is the leading cause of death for acute myocardial infarction (AMI) patients, reliable predictive factors in the acute stage, such as cardiovascular peptides, have not yet been identified. METHODS AND RESULTS In 42 consecutive AMI patients with CS on admission, successfully treated by primary percutaneous(More)
AIMS It has been suggested that obstructive sleep apnoea syndrome (OSA) may be a direct cause of left ventricular (LV) systolic dysfunction. This study was designed to examine our hypothesis that OSA inhibits the recovery of LV function in patients with acute myocardial infarction (AMI). METHODS AND RESULTS Our 86 consecutive first-AMI patients underwent(More)
BACKGROUND The predictors of cardiac rupture (CR) in patients with acute myocardial infarction (AMI) treated with successful primary coronary angioplasty have not been identified. METHODS AND RESULTS Of 433 consecutive AMI subjects who underwent reperfusion by primary coronary angioplasty within 24 h of onset, CR occurred in 11 (2.5%), free wall rupture(More)
BACKGROUND Our study was planned to investigate the relationship between plasma levels of serum amyloid A protein (SAA) concentrations and the subsequent left ventricular systolic function in patients with acute myocardial infarction (AMI) treated with primary coronary angioplasty. METHODS AND RESULTS Reperfusion by primary percutaneous coronary(More)
BACKGROUND The aim of the present study was to investigate the relationship between plasma concentrations of endothelin (ET)-1 and clinical outcome (including mortality) and left ventricular (LV) systolic function in acute myocardial infarction (AMI). METHODS AND RESULTS The study group comprised 110 consecutive first-AMI patients who were successfully(More)
The purpose of this study was to investigate the relationship between plasma adrenomedullin concentration levels and left-ventricular systolic function in patients with acute myocardial infarction (AMI), and to assess whether these findings can be used to predict clinical outcomes, including mortality. One hundred twenty-four consecutive first AMI attack(More)
OBJECTIVES Smokers with acute myocardial infarction have lower mortality rates than non-smokers despite increased risk for coronary artery disease. This study assessed the effects of smoking on complications and outcomes after acute myocardial infarction, and investigated the relationship between the clinical factors and the paradoxical effects of smoking(More)
The objective of the present study was to compare left ventricular (LV) function and clinical outcomes in diabetics versus nondiabetics with acute myocardial infarction (AMI) treated by primary coronary angioplasty. A total of 327 consecutive AMI subjects were reperfused by primary coronary angioplasty within 12 hours from onset. Diabetes mellitus (DM) was(More)
