Many trials have shown that calcium channel blockers (CCBs) can reduce the cardiovascular (CV) events in patients with coronary artery disease (CAD). The mechanisms of this effect could be associated with plaque regression due to the anti-atherosclerotic properties of CCBs. The goal of this study is to determine the effects of CCB on volumetric quantitative(More)
Coronary artery calcification (CAC) was assessed by cinefluoroscopy and its extent was scored (CAC score) in 2,163 consecutive patients undergoing coronary angiography, based on the angiographic and clinical data, the patients were categorized into 8 types of coronary artery disease (CAD). The CAC score was lowest in angiographically normal subjects(More)
A 57-year-old man with acute myocarditis was transferred to our hospital from a local clinic. The patient experienced unexpected sudden cardiac arrest 16 h after admission. Mechanical cardiopulmonary support was started using percutaneous cardiopulmonary support, intra-aortic balloon pumping (IABP), continuous hemodialysis filtration, and temporary cardiac(More)
BACKGROUND Risk scores and cardiac biomarker tests allow clinicians to accurately diagnose acute coronary syndrome (ACS) and perform early risk stratification. However, few investigations have evaluated the use of these risk scores and biomarkers for predicting risk of cardiovascular events in drug-eluting stent (DES) era. METHODS This prospective cohort(More)
A 54-year-old woman was referred to our hospital for symptomatic sinus bradyarrhythmia with a sinus pause of 8 seconds. She was diagnosed with dextrocardia during childhood and discovered to have heterotaxy syndrome when she had an appendectomy during her teenager years. Chest and abdominal examinations by computed tomography showed multiple spleens located(More)
A healthy teenage Japanese girl was admitted to our hospital after experiencing out-of-hospital cardiac arrest. She had attempted to commit suicide by taking 4,950 mg of disopyramide and 12 mg of flunitrazepam. Mechanical cardiopulmonary support was started with percutaneous cannulation of the femoral vessels. Several days later, a blood culture tested(More)
BACKGROUND A rapid rule-out or rule-in protocol based on the 0-hour/1-hour algorithm using high-sensitivity cardiac troponin T is recommended by the European Society of Cardiology. However, Asian data are not available. METHODS This prospective cohort study included 413 patients with suspected non-ST elevation myocardial infarction in 3 hospitals in Japan(More)
Objective: Psychological triggers, such as emotional stress, increase the incidence of acute cardiovascular events. The association between soccer championships and risk of cardiovascular events remains controversial. A World Cup Soccer (WCS) match involving a national team might be a strong enough trigger to induce cardiovascular events. However, there are(More)
