Residual myocardial hyperemia in regadenoson stress/rest quantitative perfusion cardiac magnetic resonance.

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
purposeThis study sought to investigate the presence of residual myocardial hyperemia on the recovery phase in patients undergoing stress CMR. MATERIAL AND
methodsFifty patients with clinical indication for stress CMR underwent quantitative perfusion imaging in resting conditions, after regadenoson-induced hyperemia (400 mcg, 5 mL), and 10 min after recovery with euphylline. Studies showing hypoperfusion due to ischemia and/or prior myocardial infarction were excluded. Global myocardial blood flow during rest (MBF
resultsA total of 30 patients (22 males, mean age of 62.7 ± 1 years) were included in the analysis. Global MBF
conclusionDespite the use of euphylline to counteract the vasodilator effect, MBF does not completely revert to resting values and MBF
