Paucity of anginal symptoms and stress-induced perfusion abnormalities in ischemic cardiomyopathy.
Article in Journal of nuclear cardiology : official publication of the American Society of Nuclear Cardiology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWe sought to investigate whether the paucity of anginal symptoms in patients with ischemic cardiomyopathy reflects a reduction in the severity of stress-induced myocardial ischemia. METHODS AND
resultsWe selected 38 patients with coronary artery disease and severe left ventricular dysfunction (ejection fraction [EF] <or=25%) (group 1), who underwent stress gated single photon emission computed tomography. In parallel, we selected 2 groups of 38 patients with coronary artery disease and EF between 26% and 45% (group 2) or EF greater than 45% (group 3), matched to group 1 patients. Effort angina was less frequent in group 1 (29%) than in group 2 (50%) and group 3 (82%) (P = .023). Stress-induced perfusion abnormalities, identified by the summed difference score (SDS), were less extensive in group 1 (mean SDS, 3 +/- 3) than in group 2 (mean SDS, 6 +/- 5) and group 3 (mean SDS, 8 +/- 4) (P = .019), whereas perfusion abnormalities at rest (summed rest score [SRS]) were more extensive in group 1 (mean SRS, 12 +/- 4) than in group 2 (mean SRS, 6 +/- 3) and group 3 (mean SRS, 3 +/- 2) (P = .015).
conclusionThe paucity of anginal symptoms in ischemic cardiomyopathy reflects a limited extent of stress-induced myocardial ischemia and a higher extent of necrosis.
