[Surgery of evolving myocardial infarction].

Area of Science:

• Cardiology
• Cardiac Surgery

Context:

• Myocardial infarction (MI) management aims to limit infarct size for improved patient prognosis.
• Emergency coronary bypass surgery is a potential intervention for selected MI patients.
• Early intervention is crucial, with operations performed within 6 hours or later for post-infarction complications.

Purpose:

• To evaluate the efficacy and outcomes of emergency coronary bypass surgery in patients with recent myocardial infarction.
• To assess the long-term prognosis of patients undergoing bypass surgery for MI.

Summary:

• Forty-four patients with recent myocardial infarction underwent emergency coronary bypass surgery within 15 days of onset.
• Eleven patients were operated on within 6 hours, while 33 had later surgery due to post-infarction angina or incomplete MI.
• One perioperative death occurred. Follow-up of 39 patients at 33 months showed 2 with angina, 1 with dyspnea, and the rest asymptomatic.

Impact:

• Coronary bypass surgery appears to be an effective treatment strategy for selected patients with recent myocardial infarction.
• The procedure demonstrates potential for long-term symptom relief and improved quality of life post-MI.
• This study supports the consideration of bypass surgery in managing specific cases of acute myocardial infarction.
