Effect of aorta-coronary bypass operation on factors precipitating angina
Insights
Aorta-coronary bypass surgery significantly relieved angina pectoris symptoms in most male and female patients one year post-operation. Non-operated patients with mild coronary obstruction also showed symptom improvement.
Area of Science:
- Cardiology
- Cardiac Surgery
- Vascular Surgery
Background:
- Angina pectoris is a common symptom of coronary artery disease.
- Aorta-coronary bypass surgery is a common intervention for severe cases.
- Understanding long-term symptom relief is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the long-term efficacy of aorta-coronary bypass surgery in relieving angina pectoris.
- To compare symptom relief rates between operated and non-operated patients.
Main Methods:
- Prospective study involving patients with angina pectoris.
- A cohort underwent aorta-coronary bypass surgery.
- A control group with mild coronary obstruction did not undergo surgery.
- Symptom assessment conducted one year post-intervention/examination.
Main Results:
- 65% of male and 50% of female patients experienced total angina relief one year after bypass surgery.
- Relief was particularly notable for angina related to walking and postprandial states.
- Among non-operated patients with mild obstruction, 38% of men and 27% of women were symptom-free after one year.
Conclusions:
- Aorta-coronary bypass surgery offers significant and sustained symptom relief for angina pectoris.
- The procedure is particularly effective for activity-induced and postprandial angina.
- Non-surgical management can also lead to symptom improvement in select patients with less severe disease.
Abstract:
About two thirds (65 percent) of 271 male patients and one half of the 44 female patients who had angina pectoris prior to the aorta-coronary bypass operation experienced total relief of symptoms 1 year after the operation. This was especially apparent for angina associated with walking activity and the postprandial angina. In the nonoperated patients who had angina pectoris and only mild or no coronary artery obstruction, 38 percent of the 127 men and 27 percent of the 73 women were free of symptoms 1 year after the original examination.
