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

backgroundFragmented QRS (fQRS) complex is an electrocardiographic pattern that reflects the inhomogeneity of ventricular depolarization. The aims of this study were to determine the prognostic significance of fQRS for predicting in-hospital life-threatening arrhythmic complications in ST-elevation myocardial infarction (STEMI) patients, and to identify the most appropriate duration of cardiac rhythm monitoring in STEMI patients with fQRS.

methodsPatients diagnosed with and treated for STEMI at Siriraj Hospital (Bangkok, Thailand) during 2009-2012 were enrolled. Patients were divided according to fQRS status (having or not having fQRS) at hospital admission. The primary outcome was in-hospital life-threatening arrhythmic events, including sustained ventricular tachycardia and ventricular fibrillation. Time to last life-threatening arrhythmic event from hospital admission was recorded.

resultsOf the 452 patients that were included, 96 patients (21.2%) had fQRS. There were significantly more life-threatening arrhythmic events in the fQRS group than in the non-fQRS group (22.9% vs. 4.5%, respectively; p < 0.001). Median (IQR) time to last life-threatening arrhythmic event from hospital admission was significantly longer in fQRS than in non-fQRS (6.58 hr [3.08-39.34] vs. 2.59 hr [1.75-5.75], respectively; p = 0.047). Multivariate analysis identified fQRS as an independent predictor of in-hospital life-threatening arrhythmic events (OR: 4.162, 95% CI: 1.669-10.384; p = 0.002).

conclusionsThe presence of fQRS complex on admission ECG was found to be an independent predictor of in-hospital life-threatening arrhythmic events in STEMI patients. Since the time to last life-threatening arrhythmic event from admission was longer in fQRS than in non-fQRS, cardiac rhythm monitoring longer than 24-48 hr may be needed in patients with fQRS.
