BACKGROUND Sirolimus inhibits endothelial cell proliferation in vitro, but although the sirolimus-eluting stent (SES) is widely used because of the very low rates of in-stent restenosis, the influence of SES on coronary endothelial vasomotor function in humans is not well known. METHODS AND RESULTS The present study included 21 patients treated with SES,(More)
AIMS To compare the initial effect and toxicity, response duration and survival time of intra-arterial infusion therapy using a combination of cisplatin (CDDP) and docetaxel (DXT) with those using CDDP alone for treatment of recurrent head and neck cancers. MATERIALS AND METHODS Twenty-nine patients with recurrent head and neck cancers were treated using(More)
A 80-year-old woman was admitted to our hospital because of chest pain. Electrocardiography revealed ST segment elevation in the I, aVL, and V1-V5 leads. Echocardiography revealed left ventricular apical aneurysmal change with ejection fraction of 31%. Coronary angiography showed no abnormalities. Creatine kinase was not elevated in her clinical course. The(More)
OBJECTIVES This study sought to investigate the 3-year follow-up results of OLIVE registry patients. BACKGROUND Although favorable 12-month clinical outcomes after endovascular therapy (EVT) in OLIVE registry patients with critical limb ischemia (CLI) from infrainguinal disease have been reported, long-term results after EVT remain unknown. METHODS This(More)
BACKGROUND The effects of intraaortic balloon pumping (IABP) are considered to be a reduction in myocardial oxygen demand because of systolic left ventricular unloading and an increase in coronary blood flow. Although the former effect has been consistently recognized, the latter effect remains controversial. The purpose of this study was to examine the(More)
BACKGROUND The presence of coronary artery calcification (CAC) and its severity predict future cardiovascular events and is used for risk stratification. However, the association of CAC with heart failure (HF) in patients without a history of coronary artery disease (CAD) remains unclear. This study aimed to determine the correlations of CAC with N-terminal(More)
BACKGROUND Cystatin C is an endogenous marker of kidney function that overcomes the limitations of serum creatinine. High serum cystatin C levels have been associated with increased cardiovascular mortality and morbidity. In this cross-sectional study, we aimed to determine the associations between serum cystatin C levels and structural and functional(More)
BACKGROUND Ambulatory measurement of intrathoracic impedance (ITI) with an implanted device has potential to assess fluid accumulation in patients with heart failure (HF), but it has failed to reduce HF-related hospitalization because of a high false-positive rate. OBJECTIVE We aimed to examine whether a modified algorithm (OptiVol 2.0) could reduce(More)
