Myocardial Revascularization in Heart Failure With Reduced Ejection Fraction.
Review in Deutsches Arzteblatt international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHeart failure (HF) patients with reduced ejection fraction (HFrEF) now more commonly die of non-cardiovascular causes than they did in the past. In patients with both HFrEF and ischemic cardiomyopathy (as the cause of HFrEF or as an accompanying condition), the effect of myocardial revascularization-i.e. percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)-on long-term outcome is unclear.
methodsThis review is based on publications that were retrieved by a selective search of the literature for pertinent clinical studies and current guidelines.
resultsDrug treatment for HFrEF has markedly prolonged these patients' survival. In a comparative study, HF pharmacotherapy was found to add an average of 8.3 years to the lifespan of a 55-yearold patient with HFrEF. Three of the four randomized controlled trials on revascularization procedures were conducted prior to the major pharmacotherapy improvements leading to better outcomes in HF patients over the past decade. These trial data indicate a long-term benefit from CABG compared to medical treatment alone in patients with HFrEF and severe coronary heart disease. For example, in the STICH trial, the hazard ratio for death from any cause after a follow-up time of nearly 10 years was 0.84 (95% confidence interval, [0.73; 0.97]). The role of pre-procedural myocardial viability and ischemia testing remains to be fully determined. The choice of method for myocardial revascularization should be discussed within an interdisciplinary cardiac team in consideration of the patient's symptoms and ischemic burden, the complexity of the coronary findings, as well as the patient's perioperative risk and current medical HF therapy. No RCTs comparing CABG to PCI are yet available.
conclusionOptimal guideline-directed medical therapy is a key determinant of long-term survival in patients with HFrEF.
