Left ventricular wall movement in heart failure.

P Carson, L Kanter

    British Medical Journal
    |October 9, 1971
    PubMed
    Summary
    This summary is machine-generated.

    Echocardiograms reveal improved left ventricular wall motion after heart failure treatment. Diastolic motion rates, however, remain lower than in healthy individuals, suggesting reduced ventricular compliance.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Physiology

    Background:

    • Left ventricular failure is a critical condition affecting heart function.
    • Echocardiography is a key diagnostic tool for assessing cardiac performance.
    • Understanding changes in ventricular wall motion is crucial for treatment evaluation.

    Purpose of the Study:

    • To assess changes in left ventricular wall motion following treatment for heart failure.
    • To compare diastolic motion rates in heart failure patients with healthy controls.
    • To evaluate echocardiography as a method for assessing ventricular function.

    Main Methods:

    • Echocardiograms were performed on 24 patients with left ventricular failure upon admission and after clinical improvement.
    • Ventricular wall motion, including anterior and posterior movement, was analyzed.

  • Diastolic motion rates were compared between the patient group and a control group of healthy men.

    • Main Results:

    • Significant increases in both anterior and posterior motion of the posterior left ventricular wall were observed post-treatment.
    • Diastolic motion rates in heart failure patients were consistently lower than in healthy controls, both before and after treatment.
    • Echocardiographic assessment of ventricular function was found to be quick and reliable.

    Conclusions:

    • Treatment for left ventricular failure leads to improved left ventricular wall motion.
    • Reduced diastolic motion rates post-treatment may indicate persistent alterations in left ventricular compliance.
    • Echocardiography provides a valuable, rapid assessment of ventricular function and response to therapy.
