Morici N, De Rosa R, Crimi G, et al. - Researchers compared patients aged ≥ 75 years admitted for an acute coronary syndrome (ACS) with or without prior history of coronary artery bypass (CABG) in terms of their prognosis. From three multicentre studies (the Italian Elderly ACS study, the LADIES ACS study and the Elderly ACS 2 randomised trial), enrollment of 2,253 ACS patients [aged 81 (78-85) years] was done; of these, 178 (7.9%) had prior CABG and 2,075 (92.1%) were without. Although there was a higher burden of cardiovascular risk factors, lower ejection fraction and higher creatinine values on admission among patients with prior CABG, prior CABG did not show any statistically significant association with 1-year outcome even after adjustment for the most relevant covariates (gender, age, prior MI, type of ACS, left ventricular ejection fraction and serum creatinine on admission).
