Why the study?

Does coronary artery bypass graft surgery alter long-term heart rate dynamics in elective CABG patients?

Population

25 elective CABG surgery patients

Comparison

Coronary artery bypass graft (CABG) surgery vs Preoperative baseline (1 week before operation)

Design

Cohort

Follow-up

up to 12 months

Authors

Discussion

Member takes

Implication

Persistent HRV reduction after CABG may reflect lasting autonomic shifts; leaves open prognostic relevance in observational data.

Structured PICO

Does coronary artery bypass graft surgery alter long-term heart rate dynamics in elective CABG patients?

Population

25 elective CABG surgery patients

Intervention

Coronary artery bypass graft (CABG) surgery

Comparator

Preoperative baseline (1 week before operation)

Outcome

Time and frequency domain measures of heart rate variability, short-term fractal scaling exponent (α1), approximate entropy, and power-law relationship of relative risk interval variability (β-slope)surrogate

Frequency domain measures of heart rate variability and approximate entropy remain significantly decreased up to 1 year after CABG surgery, indicating more predictable heart rate dynamics.
