Impairment of the extrusion transporter for asymmetric dimethyl-L-arginine: a novel mechanism underlying vasospastic angina.

2012

Abstract A 37-year old male patient presented with frequent angina attacks (up to 40/day) largely resistant to classical vasodilator therapy. The patient showed severe coronary and peripheral endothelial dysfunction, increased platelet aggregation and increased platelet-derived superoxide production. The endothelial nitric oxide synthase (eNOS)-inhibitor N G -nitro- l -arginine methyl ester (L-NAME) reduced superoxide formation in platelets identifying “uncoupled” eNOS as a superoxide source. Oral l -arginine normalized coronary and peripheral endothelial dysfunction and reduced platelet aggregation and eNOS-derived superoxide production. Plasma concentrations of the endogenous NOS inhibito…

[Ischemia with no obstructive coronary artery disease: microvascular angina and vasospastic angina].

2020

About 40% of patients undergoing coronary angiography for chest pain with anginal features have angiographically normal or near-normal coronary arteries. It was necessary to standardize all myocardial ischemia scenarios in stable patients in the absence of coronary artery disease, therefore the term INOCA (ischemia with non-obstructive coronary artery disease) was coined. The aim of this article is to summarize and to clarify the vast and controversial chapter of INOCA, in order to better understand the pathophysiological, nosographic, diagnostic and therapeutic aspects.

Vasospastic angina and scombroid syndrome: a case report

2012

Scombroid syndrome is a fish poisoning characterised by the onset of symptoms compatible with a pseudoallergic reaction; it is rarely also responsible of signs and symptoms of acute coronary syndromes, as demonstrated in this case report.

Executive summary of the joint position paper on renal denervation of the Cardiovascular and Interventional Radiological Society of Europe and the Eu…

2016

Renal denervation (RDN) was reported as a novel exciting treatment for resistant hypertension in 2009. An initial randomized trial supported its efficacy and the technique gained rapid acceptance across the globe. However, a subsequent large blinded, sham arm randomized trial conducted in the USA (to gain Food and Drug Administration approval) failed to achieve its primary efficacy end point in reducing office blood pressure at 6 months. Published in 2014 this trial received both widespread praise and criticism. RDN has effectively stopped out with clinical trials pending further evidence. This joint consensus document representing the European Society of Hypertension and the Cardiovascular…
