Model supports angioplasty for 1-2 vessel disease; leaves open validation by contemporary randomized trials.
Does percutaneous transluminal coronary angioplasty improve quality-adjusted life expectancy and costs compared to coronary artery bypass grafting or conservative therapy in patients with chronic stable angina?
This decision analytic model suggests that angioplasty is a reasonable alternative to CABG for single and two-vessel disease in chronic stable angina, with similar lifetime costs despite more repeat procedures.
