    This study compared cardiac imaging techniques in 110 patients. A coronary index effectively correlated vascular changes with impaired left ventricular function and asynergia.

    Area of Science:

    • Cardiology
    • Diagnostic Imaging
    • Physiology

    Background:

    • Cardiac catheterization and systolic time measurements are crucial for assessing heart function.
    • Coronary artery disease can lead to significant left ventricular dysfunction.

    Purpose of the Study:

    • To compare diagnostic methods including selective coronariography, ventriculography, and left catheterization.
    • To evaluate the relationship between coronary vascular alterations and left ventricular function.

    Main Methods:

    • A series of 110 patients underwent selective coronariography, ventriculography, and left catheterization.
    • Systolic time intervals and a coronary index were measured.
    • Left ventricular function and asynergia were assessed.

    Main Results:

    • The coronary index demonstrated a strong correlation with the incidence of asynergia.
    • Vascular alteration severity, indicated by the coronary index, was directly related to compromised left ventricular function.
    • Index values correlated with decreased DP/DT ratio, elevated telediastolic pressure, prolonged pre-ejection phase, and shortened left ventricular systole.

    Conclusions:

    • The coronary index is a valuable tool for quantifying vascular changes and their impact on left ventricular performance.
    • These findings highlight the physiopathological link between coronary artery disease severity and cardiac dysfunction.
