Recently in Heart, Lung and Circulation, Sharma et al. [
[1]
] reported an elegant meta-analysis of coronary artery bypass grafting (CABG) outcomes
in patients with poor myocardial viability. The study included seven articles with
993 patients with a median age of 54.8–67.2 years, and follow-up of between 12–125
months. The absence of an interaction between myocardial viability and gain from CABG
in this study indicates that estimation of myocardial viability alone should not be
the deciding factor in selecting the best therapy for these patients. However, the
studies were not powered to assess outcomes post CABG and had the limitation of significant
heterogeneity in viability assessment—we congratulate the authors on their attempts
to adjust for heterogeneity through use of a random-effects model.Keywords
