L’artériopathie des membres inférieurs en médecine générale. Quelle prise en charge ?

Abstract

Objective The purpose of this study was to analyze the results of the ATTEST study in order to evaluate general medicine management practices for peripheral arterial disease (PAD). Our analysis was based on the guidelines for good practice which recommend measurement of the systolic pressure index (SPI), search for other localizations of atherothrombosis, treatment of risk factors including smoking, walking exercises, and long-term prescription of anti-platelets. Methods ATTEST is a cross-sectional multicentric observational epidemiologic study conducted in metropolitan France. The study has recruited 8.475 analyzable patients with symptomatic PAD alone (3811 patients) or associated with other atherothrombotic localizations (2416 patients) or other cardiovascular diseases (2248 patients). These patients were followed by 3020 physicians. The current analysis thus included 6227 patients (81.2% men, 18.8% women, mean age 67.2 years), including 78.8% who had reached the stage of intermittent claudication. Risk factors included current or past smoking (61%), hypercholesterolemia (66.3%), hypertension (63.1%) and diabetes mellitus (26%). Results Arterial duplex Doppler exams of the lower limbs were performed in 91.20f the patients but measurement of the SPI for diagnostic purposes had been performed in only 17%. The majority (85.8%) of the patients with proven coronary artery disease or cervico-encephalic involvement had had an ECG and 69.3% had had a duplex Doppler of the supra-aortic trunks. Smoking continued in 39% of the patients and an aid to cease smoking had been prescribed for only 7% of the patients who were non-smokers for less than one year. Nearly two-thirds of the patients analyzed had received advice concerning physical activities. Finally, anti-platelets had been prescribed for 92.2% of the patients. Conclusions The general practitioner plays a crucial role in the diagnosis and treatment of PAD. Although measurement of the SPI is recommended as an early diagnostic tool and for evaluation of severity, it had been performed in less than one-third of the patients. Search for another localization of atherothrombosis had been performed in more than half of the patients. The physicians generally delivered advice on physical exercise and prescribed anti-platelets. The fight against smoking was however largely insufficient. The results of this study warrant further optimization of the collaboration between general practitioners and vascular disease specialists.
