Why the study?

Does CABG surgery alter perioperative RR-interval dynamics and complexity, and do these changes predict clinical course?

Population

40 elective coronary artery bypass graft (CABG) surgery patients

Comparison

Coronary artery bypass graft (CABG) surgery vs Preoperative baseline values

Design

Cohort

Follow-up

up to 72 h postoperatively

Implication

Reduced alpha1 after CABG was associated with prolonged ICU stay; leaves open the role of nonlinear HRV in perioperative outcome prediction.

Structured PICO

Does CABG surgery alter perioperative RR-interval dynamics and complexity, and do these changes predict clinical course?

P
Population
40 elective coronary artery bypass graft (CABG) surgery patients
I
Intervention
Coronary artery bypass graft (CABG) surgery
C
Comparator
Preoperative baseline values (12-40 h before surgery in half the patients)
O
Outcome
Changes in RR-interval dynamics (traditional and dynamic measures of HRV) up to 72 h postoperativelysurrogate

Altered nonlinear heart rate dynamics (reduced fractal-like scaling exponent alpha1) after CABG surgery independently predict prolonged intensive care unit stay.
