Why the study?

Does coronary artery bypass grafting affect heart rate variability in patients undergoing the procedure?

Population

35 patients undergoing coronary artery bypass grafting (CABG)

Comparison

Coronary artery bypass grafting (CABG) vs Preoperative baseline (before CABG)

Design

Cohort

Follow-up

6 weeks

Implication

CABG-associated HRV attenuation should not yet change practice; leaves open its independent prognostic value.

Structured PICO

Does coronary artery bypass grafting affect heart rate variability in patients undergoing the procedure?

P
Population
35 patients undergoing coronary artery bypass grafting (CABG)
I
Intervention
Coronary artery bypass grafting (CABG)
C
Comparator
Preoperative baseline (before CABG)
O
Outcome
Power spectrum components of heart rate variability (HRV) at 1 week and 6 weeks post-CABGsurrogate

CABG causes a marked and sustained attenuation of heart rate variability up to 6 weeks postoperatively, though the prognostic significance of this change remains unknown.
