Peripheral arterial disease is common, but the diagnosis frequently is overlooked
because of subtle physical findings and lack of classic symptoms. Screening based on the

ankle brachial index using Doppler ultrasonography may be more useful than physical
examination alone. Noninvasive modalities to locate lesions include magnetic resonance
angiography, duplex scanning, and hemodynamic localization. Major risk factors for
peripheral arterial disease are cigarette smoking, diabetes mellitus, older age (older than
40 years), hypertension, hyperlipidemia, and hyperhomocystinemia. Nonsurgical therapy
for intermittent claudication involves risk-factor modification, exercise, and pharmaco-
logic therapy. Based on available evidence, a supervised exercise program is the most
effective treatment. All patients with peripheral arterial disease should undergo aggres-
sive control of blood pressure, sugar intake, and lipid levels. All available strategies to
help patients quit smoking, such as counseling and nicotine replacement, should be
used. Effective drug therapies for peripheral arterial disease include aspirin (with or
without dipyridamole), clopidogrel, cilostazol, and pentoxifylline. (Am Fam Physician

This finding implies that many 83 percent of the patients in one large study2 knew they had PAD, only 49 percent of their physicians were aware of this history.
