Amipaque in coronary angiography.

I Enge, S Nitter-Hauge, K Levorstad

    Diagnostic Imaging
    |January 1, 1979
    PubMed
    Summary

    Amipaque demonstrated fewer hemodynamic changes, such as decreased diastolic blood pressure and heart rate, compared to Isopaque Coronar during coronary angiography. Angiogram quality was comparable between the two contrast agents.

    Area of Science:

    • Cardiology
    • Radiology
    • Medical Imaging

    Background:

    • Selective coronary angiography is a key diagnostic tool.
    • Iodinated contrast media are essential for visualizing coronary arteries.
    • Comparing different contrast agents is crucial for optimizing patient safety and diagnostic accuracy.

    Purpose of the Study:

    • To compare the hemodynamic and electrocardiographic effects of Isopaque Coronar and Amipaque.
    • To evaluate the contrast transit time and angiogram quality of both agents.
    • To determine if nonionic contrast media offer advantages over ionic media in coronary angiography.

    Main Methods:

    • A comparative study involving over 130 patients undergoing selective coronary angiography.
    • Hemodynamic (blood pressure, heart rate) and electrocardiographic parameters were monitored before, during, and after contrast administration.
    • Coronary angiogram quality and contrast transit time were assessed.

    Main Results:

    • Amipaque resulted in significantly smaller decreases in diastolic blood pressure and heart rate compared to Isopaque Coronar.
    • No significant differences were observed in electrocardiographic parameters between the two contrast media.
    • A longer contrast transit time in the left coronary artery was noted with Amipaque, potentially due to viscosity or ionic/nonionic differences. Angiogram quality was equivalent for both agents.

    Conclusions:

    • Amipaque offers a potentially safer hemodynamic profile than Isopaque Coronar for selective coronary angiography.
    • The observed differences in contrast transit time warrant further investigation into the properties of ionic versus nonionic contrast media.
    • Both contrast agents provide comparable angiographic image quality.
