[Atypical and ischemic chest pain more than a year after aortocoronary bypass]
Insights
Aortocoronary bypass surgery significantly relieved angina for most patients. However, atypical chest pain persisted or worsened in some, impacting surgical outcomes for up to 30% of those with pre-existing atypical chest pain.
Area of Science:
- Cardiology
- Thoracic Surgery
Context:
- Aortocoronary bypass (CABG) is a common surgical intervention for coronary artery disease.
- Postoperative pain assessment is crucial for evaluating surgical success and patient quality of life.
Purpose:
- To assess the long-term recurrence and severity of ischemic (anginal) and atypical chest pain after aortocoronary bypass.
- To identify factors influencing postoperative pain and surgical outcomes.
Summary:
- This study followed 215 patients for over a year after CABG.
- While 76% were free of angina and 93% improved by at least one NYHA class, severe atypical chest pain remained similar pre- and postoperatively (11% vs 13%).
- Exercise-limiting atypical chest pain was significantly more frequent in patients with pre-operative atypical chest pain (30% vs 11%), impacting up to 30% of this subgroup.
Impact:
- Atypical chest pain can significantly affect patient outcomes after CABG, even when angina is resolved.
- Understanding the prevalence and impact of atypical chest pain is vital for comprehensive patient management and surgical result evaluation.
Abstract:
215 consecutive patients were followed up for more than a year (22 +/- 9 months) after aortocoronary bypass. Recurrence of ischaemic (anginal) and atypical chest pain was assessed: 54% of all patients were completely without pain postoperatively, 76% free of angina and 93% improved by at least one NYHA class. The frequency of severe atypical chest pain was similar pre- and postoperatively (11% and 13%, respectively), but nearly double that of postoperatively severe angina (13% vs 7%, P less than 0.05). Limiting atypical chest pains in patients with pre-operative atypical chest pain was much more frequent postoperatively than in patients who pre-operatively had only angina (30% vs 11%, P less than 0.005). These two patient groups did not differ with respect to age, sex, degree of vessels disease, exercise-induced ischaemia or number and patency of bypasses. Thus, exercise-limiting atypical chest pain can influence the surgical results in up to 30% of patients with pre-operative atypical chest pain (with or without typical angina).
