OBJECTIVES To determine the clinical features of a novel heart syndrome with transient left ventricular (LV) apical ballooning, but without coronary artery stenosis, that mimics acute myocardial infarction, we performed a multicenter retrospective enrollment study. BACKGROUND Only several case presentations have been reported with regard to this syndrome.(More)
In epidemiological studies, moderate alcohol consumption has been consistently associated with a reduced risk of myocardial infarction (MI). About half of Japanese show an extremely high sensitivity to alcohol (ethanol), which is due to a missense mutation from glutamic acid (Glu) to lysine (Lys) at codon 487 in an isoenzyme of aldehyde dehydrogenase(More)
The appearance of serum troponin T (tn-T) on day 1 after acute myocardial infarction (AMI) strongly depends on coronary reperfusion. In contrast, the kinetics of tn-T release after day 1 after AMI are unaffected by the reperfusion status, and reflect the degradation of myofilaments in irreversibly damaged cells. However, it is not known whether serum tn-T(More)
OBJECTIVES To investigate the pathophysiological role of adrenomedullin in myocardial infarction. PATIENTS AND DESIGN Plasma concentrations of adrenomedullin, atrial natriuretic factor, and brain natriuretic peptide were measured by radioimmunoassay in 31 patients with acute myocardial infarction over four weeks, and in 44 normal subjects. RESULTS In(More)
BACKGROUND Population-based cohort studies demonstrate that metabolic syndrome (MeS) is associated with increased risk for cardiovascular diseases and related mortalities. The present study was designed to investigate the prognostic impact of MeS in patients with acute myocardial infarction (AMI). METHODS AND RESULTS The study group was 461 AMI patients(More)
This study was conducted to assess the determinants of the procedural success and long-term clinical benefits of percutaneous transluminal balloon angioplasty (PTCA) of chronic total occlusion (CTO) in recent years. Two hundred and twenty-six consecutive patients who underwent PTCA of CTO were divided into two groups according to the procedural success (n =(More)
AIMS The clinical outcome of severe acute myocarditis patients with cardiogenic shock who require circulatory support devices is not well known. We studied the survival and clinical courses of patients with fulminant myocarditis supported by percutaneous extracorporeal membrane oxygenation (ECMO) and compared them with those of patients with acute(More)
OBJECTIVE To analyse the prodrome of acute myocardial infarction in relation to the plaque morphology underlying the infarct. DESIGN A retrospective investigation of the relation between rupture and erosion of coronary atheromatous plaques and the clinical characteristics of acute myocardial infarction. The coronary arteries of 100 patients who died from(More)
AIMS We sought to find out what factors are important for long-term prognosis, the small vessel itself or abnormal glucose tolerance, in patients treated with coronary angioplasty. BACKGROUND Patients with coronary artery disease with diabetes mellitus often show diffuse and small coronary artery narrowing. Impaired glucose tolerance has also been(More)
Women appear to be protected, until the menopause, from the development of coronary artery disease. The incidence of acute myocardial infarction in young women is very low, so there is little information on the etiology, clinical features, and prognosis for such patients. We studied 24 young female patients with acute myocardial infarction (< 50 years)(More)
