A vascular rehabilitation program was designed to increase exercise tolerance and reduce the risk of cardiovascular disease in patients with lower extremity arterial occlusive disease. Sixty-eight patients (32 men, 36 women); ages 55 to 85 years (mean, 68 years) with claudication 30 (44%), or recovering from lower extremity revascularization 36 (53%), or endovascular procedures 2 (3%) entered the vascular rehabilitation program. Each underwent a physical examination, risk factor assessment, noninvasive arterial studies, and cardiac evaluation. A history was taken from each patient also. Six patients (9%) were excluded on recognition of silent myocardial ischemia. Sixty-two patients (91%) were accepted for exercise training in a program designed to offer 24 (1-hour) monitored exercise sessions, 12 (1-hour) personalized education lectures, and development of a home maintenance exercise program. No deaths or major morbidity occurred. Seventeen patients (27%) did not finish the program, eight (13%) because of development of significant cardiac, extremity, or cerebrovascular disease and nine for nonmedical reasons. Of the 45 patients (73%) who completed the program, 38 (88%) had documented increases in walking distances of greater than 100% (122% to 450%). All 45 patients designed home exercise programs, and 88% of the smokers quit. Long-term follow-up was available on 100% of the patients. Thirty-eight patients (84%) have been followed for 2 years or more. Thirty-eight (84%) maintained or improved walking distances recorded on exit from the program. Thirty of the 36 patients (83%) who stopped smoking remained nonsmokers. Significant reductions in cholesterol were seen at 1 year, and significant reductions in triglycerides were seen at 12 weeks and 1 year. The vascular rehabilitation program resulted in an immediate improvement in exercise tolerance, reduction of known cardiovascular risk factors, and behavior modification resulting in long-term compliance. In addition, prescreening and exercise supervision identified a significant number of patients at increased cardiovascular risk in whom independent exercise may have proved dangerous.
