OBJECTIVE Statin- and exercise-therapy are both clinically beneficial by preventing cardiovascular events in patients with coronary artery disease (CAD). However, there is no information on the vascular effects of the combination of statins and exercise on arterial wall stiffness in CAD patients. METHODS The present study is a sub-analysis of PRESET study(More)
BACKGROUND The aim of this study was to elucidate the correlation between angiographic coronary vasomotor responses to intracoronary acetylcholine (ACh) injection, clinical features, and long-term prognosis in patients with vasospastic angina (VSA). METHODS AND RESULTS This is a retrospective, observational, single-center study of 1877 consecutive(More)
BACKGROUND The prevalence, clinical features, and long-term outcome of patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) associated with coronary spasm are not fully investigated. METHODS AND RESULTS This observational multicenter study enrolled 1601 consecutive patients with suspected NSTE-ACS who underwent cardiac catheterization(More)
BACKGROUND Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. METHODS AND(More)
BACKGROUND Drug-eluting stents are replacing bare-metal stents, but in-stent restenosis (ISR) remains a problem. Reactive hyperemia index (RHI) assessed by peripheral arterial tonometry evaluates endothelial function noninvasively. We prospectively assessed the prognostic value of RHI in predicting ISR after percutaneous coronary intervention. METHODS AND(More)
