[Late cardiac events of coronary bypass surgery]
Insights
This study analyzed cardiac events in 598 coronary bypass surgery patients. Key findings include a 3.8% late death rate, with acute myocardial infarction being a significant cause, impacting long-term survival.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Outcomes
- Postoperative Cardiac Events
Context:
- Analysis of 598 patients undergoing coronary bypass surgery.
- Evaluation of hospital and late mortality rates.
- Detailed examination of cardiac versus non-cardiac causes of late death.
Purpose:
- To analyze cardiac events following coronary bypass surgery.
- To determine the incidence and causes of perioperative and late cardiac events.
- To assess long-term survival and event-free survival rates.
Summary:
- Hospital and late death rates were 4.9% and 3.8%.
- Cardiac deaths (7 patients) were primarily due to acute myocardial infarction (AMI) (5 patients) and congestive heart failure (2 patients).
- Five-year survival, event-free, and non-cardiac event-free ratios were 88%, 70%, and 91%, respectively. Graft occlusion was a leading cause of postoperative AMI.
Impact:
- Provides critical data on the long-term outcomes of coronary bypass surgery.
- Highlights the significance of managing graft occlusion and coronary lesion progression post-surgery.
- Informs clinical practice regarding risk stratification and follow-up strategies for cardiac surgery patients.
Abstract:
The cardiac events of 598 patients undergoing coronary bypass surgery were analyzed. The hospital and late death was 4.9% and 3.8%, respectively. The late death were caused by cardiac events in 7 patients and non-cardiac events in 16 patients. Of 7 cardiac death, 5 patients were died of acute myocardial infarction (AMI), and 2 patients were died of congestive heart failure. 5-year survival rate, 5-year event free ratio, and 5-year non-cardiac event free ratio were 88%, 70% and 91%, respectively. Of 18 patients who suffered from AMI after operation, 5 patients died. The causes of AMI were grafts occlusion in 9 patients, progression of coronary lesions in 5 patients and unknown in 4 patients. PTCR, PTCA and rebypass surgery were performed in 4, 9 and 8 patients, respectively.
