Surgical treatment of impending myocardial infarction: report of two cases

Area of Science:

• Cardiology
• Cardiovascular Surgery

Background:

• Obstructive coronary atherosclerosis, particularly left main coronary artery stenosis, poses a significant risk of myocardial infarction.
• Early detection and intervention are crucial for managing high-risk cardiovascular conditions.

Purpose of the Study:

• To present a case series on the surgical management of two patients with impending myocardial infarction due to severe coronary atherosclerosis.
• To evaluate the clinical, electrocardiographic, and angiographic effectiveness of surgical revascularization in these high-risk patients.

Main Methods:

• Selective coronary angiography to diagnose coronary artery disease.
• Emergency surgical revascularization procedures: double aorto-coronary venous bypass and single venous bypass with Vineberg operation.
• Post-operative clinical assessment, electrocardiography, and angiography.

Main Results:

• Both patients presented with clinical and electrocardiographic signs of impending myocardial infarction.
• Coronary angiography revealed severe obstructive coronary atherosclerosis, including left main coronary artery stenosis.
• Neither patient experienced myocardial infarction following surgery.
• Both patients demonstrated excellent clinical recovery and well-being at over six months post-operation.

Conclusions:

• Emergency surgical revascularization, including aortocoronary bypass and Vineberg procedures, can be highly effective in preventing myocardial infarction in patients with critical coronary artery disease.
• Clinical, electrocardiographic, and angiographic findings support the long-term efficacy of these surgical interventions.
