Key result
Redo-CABG increasingly involves older patients with more kidney disease and longer angina-free periods.
Why the study?
The patient profile undergoing redo-coronary artery bypass surgery has changed over time, but detailed characterization of these changes was lacking.
Population
582 patients undergoing first redo-coronary artery bypass surgery from 1987 to June 2000
Comparison
Redo-CABG patients across three time periods: 1987-1991, 1992-1995, 1996-June 2000
Design
Observational cohort study analyzing preoperative data

RECABG patients are now older with more renal disease and prior PTCA; leaves open whether risk profiles have altered modern outcomes.
Observational (n=582)
The profile of patients undergoing redo-CABG has evolved to include older patients with more comorbidities and longer intervals between surgeries.
Eck et al. (2002) conducted an observational in Redo-coronary artery bypass surgery (n=582). Later time period of surgery (1996-2000) vs. Earlier time periods (1987-1995) was evaluated on Patient profile characteristics and surgical indications. Patients undergoing redo-coronary artery bypass surgery in recent years were older (P<0.001), had more kidney disease (P=0.001), and had longer angina-free periods after initial CABG (P<0.001).
