INTRODUCTION AND OBJECTIVES It is uncertain whether side branch predilatation before main vessel stenting is necessary. We evaluated the effect of side branch predilatation on outcomes in percutaneous coronary intervention for true nonleft main bifurcation determined by the Medina classification using the provisional approach. METHODS Target vessel failures (composite of cardiac death, myocar...

BACKGROUND Several studies have shown that fractional flow reserve (FFR) measurement can aid in the assessment of left main coronary stenosis. However, the impact of downstream epicardial stenosis on left main FFR assessment with the pressure wire in the nonstenosed downstream vessel remains unknown. METHODS AND RESULTS Variable stenoses were created in the left main coronary arteries and dow...

Multilayered [FeNi (100 nm)/Cu (3 nm)]5/Cu (500 nm)/[Cu nm)/[FeNi nm)]5 structures were used as sensitive elements of the magnetoimpedance (MI) sensor prototype for model experiments detection magnetic particles in blood vessel. Non-ferromagnetic cylindrical polymer rod with a small inclusion was sample mimicking thrombus The made epoxy resin an composite containing 30% weight fraction commerci...

BACKGROUND Previous studies have reported a discrepancy in baseline characteristics and outcomes after percutaneous coronary intervention between men and women. However, this finding has never been verified in the Chinese population. The present study analyzed two-year clinical outcomes after placement of coronary drug-eluting stents in Chinese men and women. METHODS From January 2005 to Dece...

BACKGROUND In the last decade, direct stenting has been proposed as an alternative strategy to conventional stenting with balloon predilation. The aim of this study was to perform a meta-analysis of randomised trials comparing a direct stenting strategy versus a conventional one. METHODS A literature search was performed using Medline, EMBASE, the Cochrane Central Register of Controlled Trial...

Thermal stress analysis of a thick-walled cylinder reinforced with functionally graded (FG) single-walled carbon nanotubes (SWCNTs) is considered in radial direction. Thick-walled cylinder is subjected to a thermal field. Two layouts of variations in the volume fraction of SWCNTs were considered in the composite cylinder along the radius from inner to outer surface, where their names are increm...

AIMS To evaluate the prognostic impact of ST depression resolution among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI in the Assessment of Pexelizumab in Acute Myocardial Infarction (APEX-AMI) trial. METHODS AND RESULTS In this study, 4729 of 5745 patients had analysable ECGs demonstrating concomitant ST-segment depression. Resolution of summation op...

OBJECTIVES The aim of this study was to assess the safety and efficacy of the implantation of Resolute zotarolimus-eluting stents (ZES) (Medtronic Inc., Santa Rosa, California) and Xience V everolimus-eluting stents (EES) (Abbott Vascular, Santa Clara, California) following strict discontinuation of dual antiplatelet therapy (DAPT) after 12 months. BACKGROUND Only limited long-term follow-up ...
