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

backgroundThe development of ST-segment depression during adenosine myocardial perfusion imaging (MPI) has been shown to be an independent predictor of subsequent cardiac events and worse outcome, particularly in association with ischemic defects. However, the prognostic significance of ST-segment depression with adenosine in patients with normal MPI is not known. METHODS AND

resultsWe performed a retrospective analysis of 3231 patients undergoing adenosine MPI. Patients with baseline electrocardiographic (ECG) abnormalities were excluded. Overall, 228 patients (7%) had ischemic ECG changes develop during adenosine infusion. Of these, 66 (29% [2% of all patients]) had normal MPI (+ECG group). An age- and sex-matched group of 200 patients with normal MPI without ECG changes served as control subjects (-ECG group). During a mean follow-up of 29 +/- 12 months, patients in the +ECG group had significantly more adverse cardiac events than those in the -ECG group (nonfatal myocardial infarction, 7.6% vs 0.5%, respectively, P = .004; subsequent revascularization, 13.6% vs 2.5%, respectively, P = .0015). Although cardiac death alone did not differ between the 2 groups (+ECG, 3.0%, vs -ECG, 1.0%; P = .25), cumulative survival free from cardiac death and nonfatal myocardial infarction was worse in patients with ST-segment depression during adenosine infusion and normal MPI (+ECG, 10.6%, vs -ECG, 1.5%; log-rank chi(2) = 11.82; P = .0006).

conclusionsPatients with normal myocardial perfusion images in whom ST-segment depression develops during adenosine administration appear to be at increased risk for future cardiac events compared with similar patients without ECG evidence of ischemia. Ischemic ECG changes during adenosine MPI should warrant further evaluation, even when perfusion images are reassuring.
