[Diabetes, heart surgery and the peripheral arteries].
Peripheral arterial disease (PAD) is an under-recognized and underestimated complication of diabetes. Prevalence of PAD in diabetic patients is 25-30%. The main reason for underreporting is the largely asymptomatic nature of PAD in diabetes. It is important to diagnose PAD as soon as possible because PAD is an important marker for systemic atherosclerosis. Patients with claudication have approximately a 30% five-year mortality rate. PAD patients die 10 years earlier than patients without this atherothrombotic disease. About 70% of the PAD patients die from coronary heart disease, 5-11% die from stroke. PAD and diabetes are comorbid conditions and are associated with the risk of death from coronary artery bypass graft surgery. The prevalence of diabetes in patients who undergo cardiac surgery is 30% and the prevalence of PAD is 18%. The presence of PAD in diabetic patients had a similar 2-fold increase in the annual incidence of death compared with diabetic patients without PAD. The theory that diabetes and PAD together is associated with small vessel disease may play a role in the cause of the higher long-term mortality seen in at least two studies (Circulation 2004; suppl II: II/41-II/44).
