    Exercise tests reveal significant correlations between patient performance and coronary artery disease severity, including angina, heart function, and overall prognosis. This helps in understanding the impact of exercise on cardiac health.

    Area of Science:

    • Cardiology
    • Exercise Physiology
    • Diagnostic Imaging

    Background:

    • Coronary artery disease (CAD) diagnosis relies on various clinical and anatomical factors.
    • Assessing exercise performance alongside coronary anatomy provides a comprehensive view of cardiac health.
    • Left ventricular function is a critical determinant of prognosis in CAD patients.

    Purpose of the Study:

    • To investigate the correlation between exercise test results and coronary artery disease characteristics.
    • To evaluate the relationship between exercise performance and left ventricular function.
    • To determine the prognostic value of exercise testing in patients with diagnosed coronary artery disease.

    Main Methods:

    • Exercise tests were conducted on 551 patients admitted for coronary angiography.

  • A computer-generated index (CI) from 0-100% was utilized to quantify coronary anatomy.
  • Data on left ventricular contraction abnormalities were systematically recorded.

    • Main Results:

    • Significant correlations were observed between exercise performance and angina grade.
    • Exercise performance showed significant correlations with coronary pathology.
    • A significant relationship was found between exercise performance and left ventricular function.
    • Exercise performance was significantly correlated with patient prognosis.

    Conclusions:

    • Exercise testing provides valuable insights into the severity and extent of coronary artery disease.
    • Exercise performance is a significant predictor of left ventricular function and long-term prognosis in CAD.
    • Integrating exercise test data with coronary anatomy assessment enhances diagnostic and prognostic capabilities.
