Right ventricular dysfunction and associated factors in patients after coronary artery bypass grafting.
Article in ARYA atherosclerosis, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundCoronary artery bypass grafting (CABG) surgery is widely accepted as a revascularization method for coronary artery disease (CAD). Despite survival benefit and improvement in quality of life, CABG may impose major morbidities and significant complications. Right ventricle (RV) dysfunction is an important complication that may affect patient's longevity and functional capacity. The aim of this study was to evaluate the relationship between RV dysfunction and some invisible parameters like inferior vena cava (IVC) size with physical capacity.
methodsIn this prospective study, 61 eligible CABG candidates were enrolled and RV function was assessed by echocardiographic parameters before CABG and one week and six months after the procedure, using tricuspid annular plane systolic excursion (TAPSE), Tei Index (TI), peak systolic movement (Sm) (cm/s), and IVC size. Functional capacity was assessed by six-minute walk test (6-MWT) 6 months after CABG.
results58 patients who did not have any perioperative RV dysfunction were remained until the end of study; mean age was 58.2 ± 7.9 years with 68.9% being men, and 3 patients died after CABG. Preoperatively, septal motion, RV indices, and IVC size were normal in all patients. The frequency of RV dysfunction according to abnormal TAPSE index, TI, and peak Sm one week after surgery was 81.0%, 79.0%, and 62.0%, respectively, and 6 months after surgery was 49.0%, 49.0%, and 37.0%, respectively. Mean walked distance in 6-MWT was significantly less in patients with RV dysfunction, older age, and higher number of involved vessels (P < 0.001).
conclusionThe significant reduction in RV function and impairment of exercise capacity after CABG in this study suggests cardiologists to pay more attention to RV assessment in follow-up visits of patients undergoing GABG.
