[Survey on adherence to hygiene and dietary rules in patients with arterial occlusive disease].
OBJECTIVE
Chronic arterial occlusive disease of the lower limbs, a common (800,000 patients in France) invalidating condition, can involve one or more arterial territories. In 90% of the cases, it is related to a more general disease, atherosclerosis. The risk factors are the same as for atherosclerosis and can be classed into three distinct groups: pathological conditions, constitutional characteristics, and lifestyle. Besides age and gender, smoking habits are by far the most predominant vascular risk factor for chronic arterial occlusive disease. Other factors include diabetes, known to play a particular role in diabetic arteriopathy, generally with more distal and quite severe lesions, high blood pressure, a less evident but certain risk factor, and hyperlipidemia, whole role in the pathogenesis of chronic arterial occlusive disease is well recognized though not predominant. These different data led us to analyze a cohort of patients with chronic arterial occlusive disease of the lower limbs to ascertain the cause of success or failure of hygiene and diet counseling.


METHODS
The study protocol included three steps. We first established the profile of a typical arteriopathy patient based on demographic data, history of the arterial disease, personal and familial medical history and lifestyle: smoking habits, physical exercise, diet. The second step was to estimate the proportion of patients following hygiene and dietary rules. Finally, we looked for the reasons why the patients succeeded or failed in following these rules. This cross-sectional study involved 1,500 practitioners. Each physician selected 3 patients, men or women aged 40 to 80 years whose arteriopathy had reached the stage of intermittent claudication. Evaluation criteria were based on the demographic data and conditions of adherence to advice as well as conditions leading to success or failure: personal motivation, familial support, the patient's knowledge of the disease, its pathophysiological mechanisms, and the way the risk factors contribute to its genesis and aggravation.


RESULTS
The sex ratio of the 3,294 recruited patients was 4.3 (2,672 men and 622 women). Disease duration and walking distance were 8.6 +/- 6 years and 418 +/- 297 meters respectively. Thirty-eight percent of the patients had undergone surgery of the lower limbs. One thousand four hundred ninety-four patients (45%) had undergone surgery for their arterial disease (lower limbs, coronary or cerebral arteries). Forty-nine percent were aware of the risk of amputation. Overall adherence to drug therapy was good for 82% of the patients. Patients were treated basically with vasoactive and platelet antiaggregates (95 and 82% of the patients respectively). Seventy-nine percent of the patients were former smokers (38% continued to smoke). Fifty-six percent had a specific regular physical activity compared with 42% prior to their disease. Seventeen percent of the patients had already tried a Mediterranean type diet (with a success rate of 69%). Among the 3, 294 patients, 950 (28.8%) followed hygiene and dietary rules well. The main reasons and/or conditions differentiating those who were successful and those who were not were, for each item: personal motivation, family support, and perception of the influence of lifestyle on disease course. These differences were highly significant (p <0.001).


CONCLUSIONS
Considering the importance of following good hygiene and dietary rules for secondary prevention of chronic arterial occlusive disease of the lower limbs, it was interesting to assess with precision the percentage of diseased patients who follow such rules. Only about 30% of the patients were successful in correcting all behaviors.
