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

backgroundFew studies with large sample sizes are available regarding patients with Wellens' syndrome. Therefore, we sought to assess the current incidence, risk factors, clinical presentation and long-term outcomes of this population.

methodsAmong a total of 3528 patients with ACS who underwent angioplasty from 2017 to 2019 in our centre, 2127 NSTE-ACS patients with culprit LAD vessels were enrolled in this study. According to electrocardiographic criteria, the patients were divided into a Wellens' group (n = 200) and non-Wellens' group (n = 1927). The primary endpoint was cardiac death; the secondary endpoint was MACCE, a composite of all-cause death, cardiac death, recurrent myocardial infarction, target lesion revascularization, heart failure and stroke.

resultsThe incidence of Wellens' syndrome was 5.7% (200 of 3528) of all ACS patients. Wellens' syndrome more often manifested as NSTEMI (69% vs. 17.5%, P < 0.001). The percentages of preexisting coronary heart disease (39.6% vs. 23%) and previous PCI (19.5% vs. 9%) were significantly higher in the non-Wellens' group than in the Wellens' group (all P < 0.001). More importantly, the proportion of early PCI was higher in the Wellens' group (68% vs. 59.3%, P = 0.017). At a median follow-up of 24 months, Wellens' syndrome was not associated with an increased risk of MACCE (P = 0.05) or cardiac death (P = 0.188).

conclusionsThe presence of Wellens' syndrome is not definitively associated with adverse prognosis in patients with NSTE-ACS. Age ≥ 65 years, diabetes, NSTEMI, eGFR < 60 ml/min and left main disease are associated with the incidence of cardiac death. Early recognition and aggressive intervention are critical, as they may help to attenuate adverse outcomes.
