Brief Summary:
Peripheral arterial disease (PAD) is a clinical setting characterized by an exceptionally high risk for cardiovascular events. Oxidative stress seems to play a role in impairing flow-mediated dilation (FMD) and contributing to atherosclerosis in patients with PAD. Cocoa seems to exert artery dilatation via oxidative stress inhibition.
OBJECTIVES: To investigate whether in PAD patients, dark chocolate elicits artery dilatation via down-regulation of NOX2, the catalytic core of NADPH oxidase.

Detailed Description:
Atherosclerosis represents the major cause of worldwide death; it is a complex phenomenon that encompasses the intricate interplay of classic cardiovascular risk factors, oxidative stress and inflammation.
Peripheral artery disease (PAD) is a clinical setting that well represents the model of widespread atherosclerosis. PAD affects 20% of patients over the age of 75. Furthermore, PAD patients are at an exceptionally high risk for cardiovascular events and the majority will eventually die of a cardiac or cerebrovascular etiology.
Polyphenol could represent a novel therapeutic strategy to counteract atherosclerosis. During the last decades, a growing interest in polyphenols resulted from prospective and epidemiological studies that showed the beneficial effects of these substances on human health. In particular, polyphenols exert their beneficial effect by inhibition of NADPH oxidase (NOX2), an enzyme directly involved in atherosclerosis; thus, the activation of this enzyme leads to an enhanced production of oxidative stress and inflammatory processes.
The objective of this study is to evaluate the effect of polyphenols on oxidative stress and inflammation and on surrogate markers of atherosclerosis in PAD patients. Polyphenols, inhibiting NOX2-mediated oxidative stress and immune-mediated process, could represent a novel therapy to reduce the high risk of cardiovascular events in PAD.
