Management of peripheral arterial disease in the elderly

Peripheral arterial disease (PAD) in the elderly can be 1) asymptomati 2) associated with intermittent claudication, or 3) cause critical limb ischemia. Persons with PA are at increased risk for all-cause mortality, cardiovascular mortality, and mortality from coronary artery disease (CAD). Hypertension, diabetes mellitus, dyslipidemie, and hypothyroidism should be treated, and smoking should be stopped. Statins reduce the incidence of intermittent claudication and increase exercise duration until the onset of intermitte claudication in persons with PAD and hypercholesterotemia. Aniplatelet drugs (eg, aspirin, clopidogrel, angiotensin-converting enzyme [ACE] inhibitors, statins) should be given to all persons with PAD. Beta blockers should be given if CAD is present Exercise rehabilitation programs and cilostazol lengthen exercise time until leg pain develops. Chelation therapy has no scientific basis and should be avoided. Revascularization or amputation may be indicated in some cases.
