OBJECTIVES Few studies have compared the long-term outcomes of endoscopic resection and surgery. The aim of this study was to compare the long-term outcomes of endoscopic resection with those of surgery for early gastric cancer (EGC). METHODS We reviewed prospectively collected data of patients who had undergone endoscopic resection (1,290 patients) or(More)
BACKGROUND Dedicated intensive care unit (ICU) physician staffing is associated with a reduction in ICU mortality rates in general medical and surgical ICUs. However, limited data are available on the role of a cardiac intensivist in the cardiac intensive care unit (CICU). OBJECTIVES This study investigated the association of cardiac intensivist-directed(More)
BACKGROUND The use of dual-antiplatelet therapy (DAPT) exceeding 12 months may increase a bleeding risk despite a lower risk of ischemic events. There is no study to compare clinical outcomes in patients treated with a single-antiplatelet drug after DAPT in the era of drug-eluting stents (DES). We sought to investigate the efficacy and safety of clopidogrel(More)
BACKGROUND High-dose aspirin has been reported to exacerbate coronary artery spasm in patients with vasospastic angina. We investigated clinical implications of low-dose aspirin on vasospastic angina patients without significant coronary artery stenosis. METHODS We included patients without significant coronary artery stenosis on coronary angiography(More)
AIMS We sought to determine a reasonable level of revascularisation using the modified residual SYNergy between percutaneous coronary intervention (PCI) with TAXus and cardiac surgery (SYNTAX) score in patients undergoing PCI. METHODS AND RESULTS In 3,460 patients with multivessel disease receiving drug-eluting stents, residual SYNTAX score (rSS) was(More)
BACKGROUND Exercise stress echocardiography (ESE) can be used to identify left ventricular (LV) dysfunction in asymptomatic chronic MR. NT-proBNP is the best marker for monitoring LV dysfunction. OBJECTIVE The aim of this study was to estimate the complementary prognostic value of ESE and NT-proBNP in asymptomatic degenerative MR with preserved LV(More)
As cardiac magnetic resonance imaging (CMR) has become widely used for evaluation of myocardial viability after acute myocardial infarction, the additional value of CMR parameters for prediction of left ventricle (LV) remodeling has been receiving interest. The aim of the study was to investigate the additional predictive value of CMR parameters for LV(More)
BACKGROUND This study aimed to evaluate the association between high-intensity staffing by a dedicated cardiac intensivist and clinical outcomes in CS. METHODS We enrolled 2923 consecutive patients admitted to a cardiac care unit (CCU) from January 1, 2012 to December 31, 2015. In January 2013, the CCU changed from a low-intensity to high-intensity(More)
BACKGROUND Data on the association between glycemic control after percutaneous coronary intervention and clinical outcomes are limited and controversial in diabetic patients. METHODS AND RESULTS We studied 980 patients with type 2 diabetes mellitus undergoing percutaneous coronary intervention using drug-eluting stents. Based on 2-year glycosylated(More)
