BACKGROUND The impact of body mass index (BMI) on outcomes after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) remains unclear. METHODS AND RESULTS A total of 3,076 patients undergoing PCI for AMI within 48 h after symptom onset were studied. Patients were divided into 4 groups according to baseline BMI: lean (<20(More)
OBJECTIVE To examine the modality and morbidity of asymptomatic ST segment elevation in leads V1 to V3 with right bundle branch block (Brugada-type ST shift). METHODS 8612 Japanese subjects (5987 men and 2625 women, mean age 49.2 years) who underwent a health check up in 1997 were investigated. Those with Brugada-type ST shift underwent the following(More)
BACKGROUND Measurement of circulating biomarkers has enabled early diagnosis and risk assessment of acute coronary syndrome. This study sought diagnostic values of the first single-point data of biomarkers obtained soon after patient arrival by comparing with scintigraphically quantified myocardial injury in patients presenting with acute chest pain at an(More)
OBJECTIVE Although risk factors of atrial fibrillation (AF) in the general population have been characterised, their impacts on patients with specific diseases are unclear. Our aim was to determine whether risk factors of AF are different in patients with and those without coronary artery disease (CAD). METHODS We enrolled 1871 consecutive patients who(More)
OBJECTIVES This study tested whether cardiac sympathetic innervation assessed by metaiodobenzylguanidine (MIBG) activity has long-term prognostic value in combination with left ventricular hypertrophy (LVH) and left atrial size in heart failure (HF) patients without reduced left ventricular ejection fraction (LVEF). DESIGN A single-centre prospective(More)
To the Editor: We read with interest a recent article in Circulation by Wichter et al 1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (123 I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but(More)
OBJECTIVE To investigate whether coronary stenting limits myocardial injury and preserves left ventricular function. DESIGN AND SETTING Prospective multicentre case-control study of primary percutaneous transluminal coronary angioplasty (PTCA) with and without stenting, performed in seven cardiovascular centres. SUBJECTS AND METHODS 45 consecutive(More)
