Prevention

Why?

• CABG reduces mortality in patients with heart failure and angina by 30% to 50%, and improves functional outcome, assessed as either improvement in ejection fraction or decrease in NYHA class. ^b
• However 5% of patients aged < 60 with mild heart failure die from surgery, and 30% of patients aged > 70 with severe heart failure and a co-morbid condition die from surgery. ^b
• There is not enough evidence to indicate whether functional status or survival improves in the absence of angina. ^b
