The effectiveness of heart bypass grafts and angioplasty procedures on five-year survival varies significantly by gender, diabetes and other factors, researchers reported at the American Heart Association’s Quality of Care and Outcomes Research Scientific Sessions 2012.
There is little agreement on how and to what degree clinical characteristics of patients influence the effectiveness of coronary artery bypass grafts (CABG) or percutaneous coronary intervention (PCI). Researchers studied five-year survival and baseline clinical variables in 105,612 Medicare beneficiaries aged 66 and older who received either multivessel CABG or multivessel PCI between 1992 and 2008. Patient age averaged 75; 42 percent were women, 92 percent were white and 33 percent were diabetic.
Five-year survival was 74.7 percent after CABG and 71.8 percent after PCI, but survival rates were significantly higher for CABG versus PCI in patients with diabetes, heart failure or peripheral vascular disease, as well as in smokers.
