The application of exercise testing to the elderly amputee.

T Kavanagh, R J Shephard

    Canadian Medical Association Journal
    |February 3, 1973
    PubMed
    Summary

    Elderly amputees with peripheral vascular disease often experience myocardial ischemia, limiting their exercise capacity. This significantly impacts their potential for useful ambulation and rehabilitation.

    Area of Science:

    • Gerontology
    • Cardiology
    • Vascular Surgery

    Background:

    • Peripheral vascular disease is common in elderly amputees.
    • Pre-existing cardiac conditions and digoxin use are prevalent in this population.
    • Assessing exercise capacity is crucial for rehabilitation planning.

    Purpose of the Study:

    • To evaluate the exercise capacity of elderly amputees with peripheral vascular disease.
    • To identify factors limiting exercise tolerance in this group.
    • To inform exercise prescription and assess ambulation potential.

    Main Methods:

    • Review of case histories for 62 elderly amputees.
    • Analysis of previous medical history including infarction, heart failure, and digoxin therapy.
    • Arm ergometer testing to assess myocardial ischemia and oxygen intake.

    Main Results:

    • Two-thirds of patients exhibited myocardial ischemia during arm ergometry.
    • Many patients could not achieve their theoretical maximum oxygen intake due to ischemia.
    • Prevalence of prior cardiac events and digoxin use was high.

    Conclusions:

    • Myocardial ischemia is a significant limitation to exercise capacity in elderly amputees with peripheral vascular disease.
    • Current exercise capacity may not support the demands of useful ambulation for many.
    • Rehabilitation strategies must consider cardiac limitations in this patient group.
