    Increased interventricular septum thickness is linked to reduced heart function. This study confirms that greater septum hypertrophy quantitatively impairs its systolic thickening, impacting overall cardiac health.

    Area of Science:

    • Cardiology
    • Echocardiography
    • Cardiac Physiology

    Background:

    • The interventricular septum's diastolic thickness is a key cardiac parameter.
    • Septal function, measured by systolic thickening, is crucial for efficient heart contraction.
    • Hypertrophy of the interventricular septum can potentially impair cardiac function.

    Purpose of the Study:

    • To investigate the relationship between interventricular septum diastolic thickness and its systolic function.
    • To determine if increased septum thickness correlates with decreased septal function.
    • To confirm the hypothesis of quantitatively dependent deterioration of septum function with hypertrophy.

    Main Methods:

    • Utilized single-beam echocardiography for cardiac assessment.
    • Examined 55 individuals, including healthy subjects and patients with cardiac diseases.

  • Excluded participants with reversed septum motion or local dyskinesis.

    • Main Results:

    • Identified an exponential correlation between septum thickness and function (systolic thickening percentage).
    • The correlation was statistically significant (p < 0.001, r = -0.805).
    • Demonstrated a clear inverse relationship: thicker septa exhibited poorer function.

    Conclusions:

    • Confirmed the hypothesis that interventricular septum function deteriorates quantitatively with increasing hypertrophy.
    • Septal thickness is a significant predictor of impaired septal systolic thickening.
    • Echocardiography is effective in assessing this relationship in various cardiac conditions.
