Stent fracture was likely to be affected by mechanical stress provoked by rigid structures and hinge points. Stent fracture might be associated with the high incidence of target lesion revascularization.
Background and Purpose-Prevalence of carotid artery stenosis in patients with coronary artery disease (CAD) is unknown in Japanese population. Methods-The study populations consisted of 632 consecutive patients who underwent coronary angiography because of suspicion of CAD. All patients underwent carotid ultrasonography to screen carotid artery stenosis before coronary angiography. We defined echographic carotid stenosis as area stenosis of Ͼ50% or peak systolic velocity of Ͼ200 cm/s.
Neointimal growth following SES implantation is more pronounced in patients with renal insufficiency, especially those undergoing dialysis, compared with patients with normal renal function. Regardless of the beneficial effect of SES, the increased risk of MACE mainly due to high incidence of target vessel revascularization in the subgroup of patients with renal insufficiency should be taken into account.
respiratory syndrome coronavirus 2, but it can also cause thromboembolic complications through coagulopathy. 3,4 In particular, several studies reported a high prevalence of venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT) in hospi-T he coronavirus disease 2019 (COVID-19) was first reported in Wuhan, China, in December 2019, and has become a huge threat worldwide as a pandemic. 1,2 The main pathophysiology of COVID-19 is a respiratory infectious disease caused by the severe acute
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
