Linder R, et al. – The national guidelines for treatment of chronic coronary heart disease (CHD) recommend surgical coronary aortic bypass grafting (CABG) rather than percutaneous coronary intervention (PCI) for patients with a coronary three–vessel disease. Researchers used claims data containing records of almost 10 million patients of the largest German statutory health insurance fund (Techniker Krankenkasse) to measure adherence to the guidelines for treatment of groups of patients with one–, two–, and three–vessel CHD, respectively. Findings revealed that these patients were not always treated in accordance with the recommendations of the national guidelines. This study suggested that the best revascularisation strategy for each patient with two– and three–vessel disease should be decided upon by an interdisciplinary discussion between both cardiologists and cardiac surgeons.
