[Secondary prevention of coronary events by coronary artery bypass surgery]

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• Coronary atherosclerosis is a prevalent condition requiring effective treatment strategies.
• Coronary artery bypass surgery (CABG) is a key intervention for advanced coronary artery disease.
• Comparing CABG with medical and interventional therapies is crucial for optimal patient care.

Purpose of the Study:

• To review the epidemiology of coronary atherosclerosis.
• To emphasize the efficacy of surgical treatment compared to other therapies.
• To highlight potential improvements in surgical outcomes.

Main Methods:

• Review of epidemiological data on coronary atherosclerosis.
• Analysis of randomized studies comparing surgical, medical, and interventional treatments.
• Evaluation of outcomes related to ischemic events.

Main Results:

• Coronary artery bypass surgery demonstrates superiority in specific indications: left main lesions, multivessel disease with impaired ventricular function, proximal LAD lesions, and in diabetic patients.
• Surgical treatment is effective in preventing ischemic events compared to medical or interventional therapy.
• Beating heart surgery and multiple arterial conduits may enhance surgical results.

Conclusions:

• Coronary artery bypass surgery remains a highly effective treatment for specific complex coronary artery disease scenarios.
• The choice of therapy should be guided by lesion characteristics, ventricular function, and patient comorbidities like diabetes.
• Advancements in surgical techniques, such as off-pump surgery and arterial grafting, offer potential for improved long-term outcomes.
