Electrocardiographic abnormalities in centenarians: impact on survival.

Background: The centenarian population is gradually increasing, so it is becoming more common to see centenarians in clinical practice. Electrocardiogram abnormalities in the elderly have been reported, but several methodological biases have been detected that limit the validity of their results. The aim of this study is to analyse the ECG abnormalities in a prospective study of the centenarian population and to assess their impact on survival.

Influence of traditional risk factors of atherosclerosis in the development of severe ischemic complications in giant cell arteritis.

Because the prognosis of giant cell arteritis (GCA) is related to the development of ischemic complications, we sought to assess the possible influence of traditional risk factors of atherosclerosis in the development of severe ischemic complications of GCA. We conducted a retrospective study of patients with biopsy-proven GCA diagnosed from 1981 to 2001 at the single hospital for a well-defined population of almost 250,000 people. Patients were considered to have severe ischemic manifestations if they suffered visual manifestations, cerebrovascular accidents, jaw claudication, or signs of occlusive changes in large arteries of the extremities.
