1 · What the graph read from it

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.

2 · The registry

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

purposeThis study was designed to assess the relationships among myocardial viability, changes in left ventricular (LV) ejection fraction after coronary revascularization and long-term event-free survival in patients with previous myocardial infarction and LV dysfunction.

methodsWe studied 253 patients with previous myocardial infarction and evidence of dysfunctional viable myocardium as assessed by echocardiography and 99mTc-sestamibi imaging. Coronary revascularization was performed in 142 patients, while 111 were medically treated. In revascularized patients, echocardiography was repeated 12 months later to detect LV ejection fraction improvement, defined as an increase of > or =5% compared with baseline. All patients were followed for a mean period of 52+/-29 months. Cardiac death and non-fatal myocardial infarction were considered as events.

resultsEvent-free survival was higher in revascularized than in medically treated patients (P<0.001). Ejection fraction increased by > or =5% in 82 (58%) revascularized patients, and the extent of viable myocardium was the strongest predictor of such improvement (P<0.001). Event-free survival was similar for patients with (n=82) and patients without (n=60) LV ejection fraction improvement after revascularization, and it was better in revascularized than in medically treated patients in the presence of either substantial (> or =5 viable segments) or low-intermediate (1-4 viable segments) viability (both P<0.01).

conclusionIn patients with previous myocardial infarction and evidence of viable myocardium, coronary revascularization procedures improve outcome at long-term follow-up independently of LV ejection fraction improvement.
