摘要

The records of 2,265 patients who had ankle-brachial index (ABI) values computed when they underwent noninvasive lower extremity vascular testing (Visit 1) at the San Diego Veterans Administration Medical Center or at the University of California San Diego Medical Center during the 10 years prior to 1990-1994 were used to recruit 508 volunteers. The volunteers were asked to participate in a second round of vascular testing (Visit 2). At Visit 2, the volunteers completed a health history questionnaire and the San Diego Claudication Questionnaire and underwent vascular testing. ABI values were calculated for each leg as the ratio of the ankle pressure for that leg relative to the higher of the left and right brachial pressures. The lower ABI was used for Visit 1 and Visit 2; the two ABI values were not necessarily from the same leg. Change in ABI between Visit 1 and Visit 2 was computed for each patient. Patients were followed for 6 years from the time of the second vascular testing.
