Hemodynamics in diabetic renal failure.

J Berglund, R Jonasson, S K Pehrsson

    Acta Medica Scandinavica
    |January 1, 1985
    PubMed
    Summary

    Diabetics with moderate kidney disease show impaired cardiac function, specifically left ventricular dysfunction during exercise. Early kidney transplant consideration is advised for these patients.

    Area of Science:

    • Cardiology
    • Nephrology
    • Endocrinology

    Background:

    • Diabetic patients with chronic kidney disease often develop cardiovascular complications.
    • Uremia and diabetes independently affect cardiac performance.
    • The specific cardiac impact of moderate uremia in insulin-dependent diabetics requires further elucidation.

    Purpose of the Study:

    • To assess cardiac performance in insulin-dependent diabetic patients with non-dialysis-requiring uremia.
    • To identify potential contributors to cardiac dysfunction in this patient cohort.
    • To inform recommendations for managing renal complications in diabetic patients.

    Main Methods:

    • Left ventricular catheterization was performed on ten insulin-dependent diabetic patients with moderate uremia.
    • Cardiac output and stroke work were measured at rest and during exercise.
    • Left ventricular end-diastolic pressure was monitored.

    Main Results:

    • Resting cardiac output was normal in all patients.
    • Nine out of ten patients demonstrated impaired stroke work increase during exercise.
    • Elevated left ventricular end-diastolic pressure accompanied the exercise impairment.
    • Cardiac dysfunction was not solely explained by anemia, uremia severity, or fluid overload, though hypertension may contribute.

    Conclusions:

    • Diabetic patients with moderate uremia exhibit left ventricular dysfunction.
    • This dysfunction manifests as impaired cardiac performance during exercise.
    • Earlier consideration of renal transplantation may be beneficial for diabetic uremic patients compared to non-diabetics.
