Health screening for peripheral and carotid artery disease using noninvasive tools showed limited diagnostic value. Risk factors did not correlate with objective findings, suggesting health fairs are better for education than intervention.

Area of Science:

  • Vascular Medicine
  • Diagnostic Tools
  • Public Health Screening

Background:

  • Health screening for common conditions like hypertension and diabetes is established.
  • Noninvasive diagnostic tools are increasingly used in medical assessments.
  • The efficacy of screening for peripheral vascular disease (PVD) and carotid artery disease (CAD) in the general population requires evaluation.

Purpose of the Study:

  • To determine the efficacy of a health screening program for PVD and CAD.
  • To assess the utility of noninvasive laboratory diagnostic tools in a general population screening setting.
  • To evaluate the correlation between self-reported risk factors and objective vascular findings.

Main Methods:

  • Peripheral vascular disease screening involved 496 participants (mean age 35); ankle-brachial index (ABI) was measured using Doppler ultrasound.

  • Carotid artery disease screening involved 2141 asymptomatic individuals (average age 31-40).
  • Participants completed risk factor questionnaires (smoking, cardiac history, family history, leg pain).

    • Main Results:

    • In PVD screening, only one participant had an abnormal ABI (0.47); risk factors did not correlate with ABI.
    • In CAD screening, two out of 2141 individuals had lesions requiring further evaluation.
    • The incidence of cardiac disease, diabetes mellitus, and abnormal ABIs was very low in the screened populations.

    Conclusions:

    • Noninvasive screening for PVD and CAD in a general, asymptomatic population yielded few positive findings.
    • Self-reported risk factors showed no correlation with objective vascular disease markers in this study.
    • Health fairs may serve a more effective role as educational platforms rather than diagnostic intervention tools for these conditions.
