Garland lecture. Coronary arteriography: pathologic and prognostic implications

H L Abrams

    AJR. American Journal of Roentgenology
    |July 1, 1982

    Summary

    Coronary arteriography, the gold standard for diagnosing coronary artery disease, sometimes inaccurately predicts disease severity. Expert interpretation varies, yet it remains crucial for patient prognosis.

    Area of Science:

    • Cardiology
    • Diagnostic Imaging
    • Medical Diagnostics

    Background:

    • Coronary arteriography is the established in vivo gold standard for evaluating coronary artery disease (CAD).
    • Radiographic findings typically correlate well with the underlying pathology of CAD.
    • Existing noninvasive tests are often gauged against coronary arteriography results.

    Purpose of the Study:

    • To assess the accuracy of coronary arteriography in predicting the degree of coronary artery disease.
    • To investigate the variability in interpreting coronary arteriograms among experts.
    • To determine the prognostic value of coronary arteriography in patients with CAD.

    Main Methods:

    • Correlative studies comparing arteriographic findings with pathological substrates.
    • Analysis of inter- and intraindividual variations in stenosis assessment by expert interpreters.
    • Evaluation of prognostic factors derived from coronary arteriography.

    Main Results:

    • Coronary arteriography may underpredict disease severity in some patients and overpredict in others.
    • Significant inter- and intraobserver variability exists in assessing the degree of stenosis.
    • Despite limitations, arteriography remains a key prognostic indicator.

    Conclusions:

    • Coronary arteriography, while the gold standard, has limitations in accurately quantifying coronary artery disease.
    • Variability in interpretation highlights the need for standardized protocols.
    • Arteriographic findings, especially when combined with indicators like asynergy or heart failure, significantly impact patient prognosis.
