BACKGROUND First generation drug-eluting stents (DESs) were based on 316L stainless steel and coated with a permanent polymer. The vessel wall of these DESs was inflammatory and late in-stent thrombosis was reported. Hence, cobalt chromium based DES coated with a bioabsorbable polymer was an alternate choice. METHODS Cobalt chromium based DES with(More)
BACKGROUND Renal sympathetic nerves are involved in the reflective activation of the sympathetic nervous system in circulatory control. Catheter-based renal denervation (RDN) ameliorated treatment-resistant hypertension safely, but 10%-20% of treated patients are nonresponders to radiofrequency denervation. The purpose of this study was to investigate the(More)
BACKGROUND Despite great reduction of in-stent restenosis, first-generation drug-eluting stents (DESs) have increased the risk of late stent thrombosis due to delayed endothelialization. Arsenic trioxide, a natural substance that could inhibit cell proliferation and induce cell apoptosis, seems to be a promising surrogate of sirolimus to improve DES(More)
OBJECTIVE To investigate late stent malapposition or vessel remodeling post chitosan/heparin layer-by-layer self assembly coating stent (LBL) implantation in porcine. METHODS A total of 32 stents [bare metal stent (BMS, n = 9), sirolimus-eluting stent (SES, n = 11) and LBL (n = 12)] were implanted into coronary arteries of 16 porcine. Intravascular(More)
To the Editor: A 35‐year‐old man who smoked for 15 years suffered from chest pain 12 days ago before admission. He was diagnosed as myocardial infarction. Thrombolytic therapy was given consequently. The electrocardiogram showed sub‐acute inferior wall myocardial infarction. Echocardiogram showed attenuated constriction of the inferior wall with an ejection(More)
