    Insights

    This study introduces a quantitative coronarogram analysis method to assess coronary artery disease. The developed angiographic coronary index aids in evaluating lesion severity and coronary blood flow insufficiency.

    Area of Science:

    • Cardiovascular imaging
    • Quantitative coronary angiography
    • Myocardial perfusion assessment

    Background:

    • Coronary artery disease diagnosis relies on imaging techniques.
    • Assessing diffuse and segmentary lesions requires precise quantitative methods.
    • Evaluating the relationship between coronary vasculature and myocardial mass is crucial for understanding blood flow.

    Purpose of the Study:

    • To present a novel quantitative analysis method for coronarograms.
    • To introduce the angiographic coronary index (ACI) for cardiovascular assessment.
    • To enable precise evaluation of coronary artery lesions and blood flow.

    Main Methods:

    • Quantitative analysis of coronarograms.
    • Determination of average total caliber of coronary arteries.
    • Calculation of the angiographic coronary index.

    Main Results:

    • The method allows for quantitative analysis of coronary arteries.
    • Average total caliber and ACI can be determined from coronarograms.
    • The ACI reflects the coordination of the coronary bed to myocardial mass.

    Conclusions:

    • The reported method enables quantitative assessment of coronary artery disease.
    • The angiographic coronary index is a valuable parameter for evaluating lesion degree and localization.
    • ACI can be used to assess relative insufficiency of coronary blood flow.
