Management of patients with peripheral arterial disease in primary care: a cross-sectional study in Germany.
BACKGROUND
Studies in the primary care setting are of high interest for assessing the management situation of patients with manifestations of atherothrombosis.


OBJECTIVE
Therefore, we documented diagnostic procedures, characteristics, and management of patients with symptomatic and asymptomatic peripheral arterial disease (PAD).


METHODS
Prospective cross-sectional study in primary care practices throughout Germany.


RESULTS
A total of 671 patients with newly diagnosed PAD were included (mean age 69.1 years; 62.1% men). Cardiovascular risk factors were highly prevalent in the total PAD group: arterial hypertension in 84.2%, hyperlipidaemia in 75.5%, present smoking in 45.0% and diabetes mellitus in 47.3%. Atherothrombotic comorbidities were also frequent: coronary artery disease in 44.9% and cerebrovascular disease in 28.1%. For confirmation of diagnosis, patients were referred to specialists in 66.9% of cases. Overall, ankle brachial index was measured in 89.0%, and a clinical PAD score assessed in 66.6% (agreement of both measures with Cohen's kappa only, kappa = 0.039; p = 0.209). Drug treatment of risk factors (as secondary prophylaxis) in line with current guidelines was reported in a high percentage of patients: 88.6% with any antiplatelet drug, 69.3% with statins, 62.4% with angiotensin converting enzyme inhibitors, 23.5% with AT(1) receptor blockers and 43.9% with beta-blockers. Between asymptomatic and symptomatic PAD, differences in the risk factor/comorbidity profiles were small; however, the latter group received intensified treatment.


CONCLUSIONS
Our findings confirm that patients with PAD pose a substantial challenge to physicians because of their high number of comorbidities. Compared with previous studies, management of such patients appears to have improved.
