Summary
Exercise treadmill testing (ETT) provides prognostic information for cardiovascular events. While many ETT variables are equally important for men and women, exercise capacity is more critical for men, and chronotropic incompetence is more critical for women.
Area of Science:
- Cardiology
- Exercise Physiology
- Preventive Medicine
Background:
- Exercise treadmill testing (ETT) is utilized for diagnosing coronary artery disease.
- Limited data exists on gender-specific prognostic value of ETT variables.
Purpose of the Study:
- To investigate gender differences in the prognostic importance of ETT variables.
- To assess the association between ETT parameters and adverse cardiovascular outcomes.
Main Methods:
- A cohort of 9,569 patients undergoing ETT was analyzed.
- ETT variables including exercise capacity, symptoms, ST-segment deviations, heart rate recovery, and chronotropic response were evaluated.
- Outcomes of all-cause death and myocardial infarction (MI) were assessed, with models stratified by gender.
Main Results:
- Exercise capacity and heart rate recovery predicted all-cause death in the overall population.
- Exercise capacity, chest pain, and ST-segment deviations predicted MI.
- Abnormal exercise capacity was a stronger predictor of death in men, while chronotropic incompetence was a stronger predictor of MI in women.
Conclusions:
- Many ETT variables have similar prognostic value in men and women.
- Exercise capacity holds greater prognostic importance for men regarding mortality.
- Chronotropic incompetence is a more significant predictor of MI in women.
