Coronary artery bypass in patients with impaired left ventricular function

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Severe left ventricular dysfunction in coronary artery disease (CAD) patients poses treatment challenges.
• Myocardial revascularisation is a potential therapeutic option for improving outcomes in this high-risk group.

Purpose of the Study:

• To evaluate the efficacy and safety of myocardial revascularisation in patients with CAD and severe left ventricular dysfunction.
• To assess the impact on survival rates and symptom improvement.

Main Methods:

• Retrospective analysis of 22 consecutive patients with CAD and severe left ventricular dysfunction (LVEF 10-35%) undergoing aorta-coronary bypass.
• Follow-up data collected for survival and symptom assessment over a mean of 24 months.

Main Results:

• Hospital mortality was 9% (2/22), with 3 late deaths.
• 12 out of 17 assessed survivors reported symptom improvement; 3 became asymptomatic.
• Significant improvement in survival expectation and symptoms compared to medical management.

Conclusions:

• Myocardial revascularisation is a viable and safe option for selected CAD patients with severe left ventricular dysfunction.
• The procedure offers improved survival and symptomatic relief, surpassing medical therapy.
• Further research is warranted to confirm these preliminary findings in a larger cohort.
