Insights
Emergency coronary artery bypass grafting (CABG) had a 10.7% mortality rate, significantly higher than elective CABG. Arterial grafts showed 100% patency in urgent cases, suggesting their benefit for long-term results.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
Context:
- Emergency coronary artery bypass grafting (CABG) presents higher risks compared to elective procedures.
- This study analyzed outcomes for 29 emergency CABG patients between 1996 and 1998.
Purpose:
- To evaluate the hospital mortality and graft patency rates in emergency CABG.
- To identify factors influencing outcomes in urgent cardiac surgery.
Summary:
- Emergency CABG resulted in a 10.7% hospital mortality rate, significantly exceeding the 1.4% rate for elective CABG.
- Intra-aortic balloon pump (IABP) support was required in 72% of emergency cases.
- Arterial grafts, used in 86.2% of emergency cases, demonstrated 100% patency.
Impact:
- Highlights the increased risk associated with emergency CABG.
- Emphasizes the importance of patient stabilization and collaboration with cardiologists to reduce operative mortality.
- Recommends the use of arterial grafts in urgent CABG for improved long-term outcomes.
Abstract:
Between January, 1996 and December, 1998, 29 patients were undergone emergency coronary artery bypass grafting (CABG) in our institute. Age ranged 34 to 85 years (mean 65 +/- 11 years, male:female = 25:4). Of 29 emergency cases, 3 were hospital death. Hospital mortality rate was 10.7%, which was significantly higher than the hospital mortality of elective CABG (1.4%) during the same period. The necessity of IABP before CABG was 72% in emergency cases (elective surgery: 0%). Thus the use rate of arterial grafts were 86.2% in emergency cases (elective surgery: 100%), the patency of the arterial grafts were 100%. It is important to make stable condition of the patients before the operation, and therefore it is important to make contact closely with the cardiologists for making stable condition and for lowering the operative mortality. And, we should use arterial grafts for the long term result as much as possible if it is an urgent operation.
