A vizsgálatról

Mit akar kideríteni a vizsgálat

Peripheral Arterial Disease (PAD) is a highly debilitating disease that affects 202 million people around the world and about 7 million people in France. Morbi-mortality from cardiovascular events is increased in this population. Intermittent claudication is defined as a discomfort and/or pain in the legs during walking. It is the most common clinical feature of PAD.

A teljes eredeti leírásKevesebb

In claudication, primary therapeutic approach is medical treatment and advice to walk. Revascularization is only proposed when medical treatment and advice to walk for at least 3 to 6 months have failed to improve symptoms and walking ability.

Optimal medical treatment includes Antiplatelet, Lipid Lowering Drugs, AT2 antagonists / ACE Inhibitors and advice to walk.

To date, no other drug has provided consistent evidence for functional improvement in claudication, except for Cilostazol, a type-3 phospho-diesterase inhibitor (PDEi). This compound has been scarcely used in France due to cost and frequent side effect (Headache, Flush, Diarrhea, etc.) and was withdrawn as a therapy in 2010.

Sildenafil, a type 5 PDEi, is well tolerated, largely used in impotence and has interesting clinical delay and duration of action in the concept of a potential use in claudication. Preliminary data from the literature and unpublished case reports, suggest that this drug could efficiently improve symptoms and walking capacity in patients with stage 2 claudication.
