Discussion

Implication

Rising patient age and comorbidities raise postoperative morbidity after CABG; leaves open whether modern care sustains mortality stability in higher-risk groups.

Key Points

To analyze changes in patient demographics and their impact on morbidity and mortality in myocardial revascularization.
Analyzed pre-, per-, and postoperative data of 3834 patients from January 1987 to December 1995.
Divided the patient group into three cohorts: 1987-1989, 1990-1992, and 1993-1995.
Measured changes in age and comorbidities over time across different groups.
Mean age increased from 60.4 years in group A to 62.9 years in group C (P < 0.0005).
Increases in patients with insulin-dependent diabetes (P = 0.005) and other comorbidities were significant.
Postoperative morbidity increased with stable hospital mortality rates around +/- 2.5%.

How have patient characteristics and postoperative outcomes changed over time in patients undergoing primary isolated coronary bypass surgery?

Population

3,834 patients undergoing primary isolated coronary bypass operations between January 1987 and December 1995, divided into three time cohorts: 1987-1989 (n=1,292), 1990-1992 (n=1,130), and 1993-1995 (n=1,412).

Intervention

Primary isolated coronary bypass surgery in later time cohorts (1990-1995)

Comparator

Primary isolated coronary bypass surgery in the earliest time cohort (1987-1989)

Outcome

Postoperative hospital mortality and morbidityhard clinical

The patient population undergoing coronary bypass surgery has become older and more comorbid over time, leading to increased postoperative morbidity despite stable hospital mortality rates.
