title: [Early diagnosis of arteriopathy of the legs using measures adapted to general practitioners: the systolic index and pulse perception].
abstract: Atherosclerotic lower-limb arteriopathy is a serious disease. Its prevalence often underestimated when relying only on questioning the patient. A simple early detection method is the systolic index, i.e. the ratio of systolic ankle over brachial pressure. This ratio should normally be greater than 0.9. Lower values indicate detectable arterial obstruction as revealed by reduced peripheral perfusion. Under 0.75 patients are considered as suffering from peripheral vascular disease and require further investigations and specialist opinion. With an index between 0.75 and 0.90 patients are classified as stage I or II of the disease. In a survey by 180 General Practitioners, which were trained by angiologists to measure ankle pressure, more than 1,400 patients, between 40 and 75-years old, with at least one vascular risk factor (hypertension, diabetes, lipids, tobacco) were selected. Tobacco was the most prevalent vascular risk factor, then diabetes (particularly in men). 23.8% of patients recorded values between 0.90 and 0.75 and thus suffering from peripheral vascular disease (certainly age dependent). Clinically absent pulses at the posterior tibial and the dorsalis pedis artery were found is 19 and 27% of patients respectively. Most of the patients received a pharmacological substance allowing to check this index sensitivity. Thus systolic index is a simple low cost method for early detection and care and more general utilisation is proposed.
