Summary

Introduction:
Cardiovascular rehabilitation is currently part of standard therapy in patients after acute coronary syndrome. The interventional cardiovascular rehabilitation training program is a part of the second rehabilitation phase, which is a key point in all secondary‑ preventive processes in patients with coronary artery disease. Patients are hemodynamically adapted to normal physical exercise, their aerobic capacity is gradually increased, and they learn about the principles of regular aerobic‑resistance training.

Design:
This study is focused on assessing the impact of modified aerobic‑resistance training on cardiorespiratory parameters in patients after an acute coronary event.

Methods:
The study included 106 patients (85% men), mean age 60.4 ± 10.9 years, with a left ventricular ejection fraction 57.4 ± 7.2%. The time form acute coronary event to the start of the training program was 35 ± 8 days; in patients after coronary artery bypass graft this was 50 ± 16 days. All patients completed a 2-month aerobic‑resistance training program with 3 sessions a week. A training session lasted 100 min (including 60 min of aerobic training).

Results:
The completion of the intervention training program led to a significant increase in work tolerance (1.8 ± 0.3 vs. 2.0 ± 0.4 W/ kg; p < 0.001) and peak oxygen consumption (22.8 ± 4.5 vs. 25.9 ± 5.5 pVO₂; p < 0.001). Other results observed were a non‑significant decrease in resting heart rate, systolic and diastolic blood pressure values.

Conclusion:
A modified intervention training program leads to improvements in aerobic capacity, which is one of the major prognostic factors in patients after acute coronary syndrome.
