BACKGROUND Sodium bicarbonate has been postulated to prevent contrast-induced acute kidney injury (CI-AKI) by various mechanisms, although the reports are conflicting. METHODS AND RESULTS We searched MEDLINE, EMBASE, and the Cochrane databases for randomized controlled trials that compared a sodium chloride with a sodium bicarbonate hydration regimen with(More)
BACKGROUND Because stress-induced cardiomyopathy (SIC) is increasingly being observed during routine daily practice, we sought to explore the clinical features and factors that determine the outcome of SIC in a tertiary referral hospital. METHODS Patients with typical left ventricular (LV) takotsubo (apical ballooning) or inverted takotsubo on(More)
OBJECTIVES The aim of this study was to systematically review and perform a meta-analysis of randomized trials and observational studies of intravascular ultrasound (IVUS)-guided versus angiography-guided implantation of drug-eluting stents (DES). BACKGROUND Although studies in the bare-metal stents era suggested that there were clinical benefits to IVUS(More)
BACKGROUND Despite several case reports of sirolimus-eluting stent (SES) fracture and concern regarding restenosis after successful SES implantation, the clinical characteristics of this problem are not well known. METHODS Clinical records and angiographic films of patients who received follow-up coronary angiography between February 2005 and October 2006(More)
OBJECTIVES To evaluate the impact of cilostazol on the angiographic and clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) with stents and treated with aspirin and thienopyridine. METHODS A total of 11 randomized controlled trials including 8,525 patients comparing triple antiplatelet therapy (aspirin, thienopyridine and(More)
BACKGROUND Both new dual antiplatelet therapy (DAT; aspirin and prasugrel) and triple antiplatelet therapy (TAT; aspirin, clopidogrel and cilostazol) are more potent than classic DAT (aspirin and clopidogrel). We compared the antiplatelet efficacy between new DAT and TAT in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary(More)
BACKGROUND Recent studies have shown that post-clopidogrel high platelet reactivity (HPR), assessed by a point-of-care assay, is associated with a higher risk of adverse events after percutaneous coronary intervention (PCI). We assessed the clinical impact of HPR by the VerifyNow P2Y12 point-of-care assay in 181 patients with ST-segment elevation myocardial(More)
Loss-of-function (LOF) variants of cytochrome P450 2C19 (CYP2C19) have been hypothesized to be associated with lesser degrees of platelet inhibition and increased risk for recurrent ischemic events in patients with coronary artery disease on clopidogrel therapy; however, studies from Western countries have yielded mixed results. We aimed to assess the(More)
We sought to test whether the peak systolic velocity of mitral annular longitudinal movement (S') measured by pulsed tissue Doppler imaging technique is useful to assess global left ventricular (LV) contractility under various LV inotropic conditions, including regional wall motion abnormality. In addition, the accuracy of S' relative to LV ejection(More)
Clinical outcomes for unprotected left main coronary artery (ULMCA) disease between coronary artery bypass grafting (CABG) and drug-eluting stents (DESs) remain controversial. We aimed to compare the safety and efficacy of percutaneous coronary intervention (PCI) using DESs with CABG in patients with ULMCA disease. Databases were searched for clinical(More)
