[Long-term clinical results after intervention using aorto-coronary bypass]

Area of Science:

• Cardiology
• Cardiac Surgery

Context:

• Long-term outcomes of coronary artery bypass grafting (CABG) are crucial for patient management.
• Evaluating the durability of symptomatic improvement after CABG is essential.

Purpose:

• To assess the survival and symptom recurrence rates 6-10 years after isolated coronary artery bypass grafting.
• To identify predictors of long-term prognosis and symptom evolution post-CABG.

Summary:

• This study followed 294 patients for 6-10 years after CABG, reporting a 10-year cardiac death expectancy of 10% and non-fatal myocardial infarction of 11.2%.
• Initially, 56% of patients were angina-free one year post-surgery, decreasing to 45% by the 10-year follow-up, indicating temporary symptomatic benefit.
• Early clinical status post-CABG significantly predicted long-term outcomes, with symptom-free patients experiencing fewer severe ischemic events.

Impact:

• Coronary artery bypass grafting demonstrates a substantial clinical impact, though symptomatic improvement may not be permanent.
• Left main stenosis and perioperative myocardial damage were identified as factors influencing long-term prognosis.
• Graft patency and completeness of revascularization impact early clinical results, while perioperative myocardial damage affects symptom recurrence.
