Patients diagnosed with coronary artery disease (ICD-10: I25)
Conditions
Interventions
Group 1: Observational group: Cardiac patients – SEISMAX group
Description:?Patients with coronary artery disease undergoing routine cardiopulmonary exercise testing (CPET) are additionally examined u
total time per session is approximately 10–15 minutes.
CPET is performed as per clinical routine with continuous ECG and blood pressure monitoring under medical supervision.
Participation is voluntary

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Agreement between VO2max values estimated by seismocardiography and those directly measured by cardiopulmonary exercise testing (CPET) in cardiac patients. | — |
Secondary
| Measure | Time frame |
|---|---|
| * Assessment of the influence of demographic and clinical characteristics (e.g., age, sex, body weight) on the accuracy of VO2max estimation by seismocardiography (SCG). * Analysis of the correlation between SCG-derived VO2max and ventilatory thresholds (e.g., anaerobic threshold). * Evaluation of the practicability and acceptance of SCG measurement in routine clinical settings. | — |
