Relation of left-ventricular dyssynchrony by phase analysis of gated SPECT images and cardiovascular events in patients with implantable cardiac defibrillators.
Article in Journal of nuclear cardiology : official publication of the American Society of Nuclear Cardiology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 54 papers, 1 of them a synthesis that pooled 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.
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
backgroundLeft-ventricular (LV) dyssynchrony could be measured by gated SPECT myocardial perfusion imaging (MPI). This study examined the relation between the degree of dyssynchrony and outcome in patients with implantable cardiac defibrillators (ICDs). METHODS AND
resultsWe studied 70 patients with ICD and LV ejection fraction (EF) <.40 by gated MPI (performed within 6 weeks of the device implantation). The images were re-processed using phase analysis to derive phase standard deviation (SD) and histogram bandwidth. All-cause mortality and appropriate ICD shocks were identified as the primary endpoint. There were 87% men, aged 62 +/- 11 years. The EF was 26 +/- 8% (range 12%-39%). The phase SD was 51 degrees +/- 20 degrees (range 12 degrees -99 degrees ) and the histogram bandwidth was 157 degrees +/- 72 degrees (range 21 degrees -327 degrees ). The SD and bandwidth were significantly greater than corresponding values in patients with normal EF (15.8 +/- 11.8 degrees and 42.0 +/- 28.4 degrees , respectively, P < .0001, each). At 1 year, 8 patients (11%) died or had shocks. The patients with events had higher phase SD than those without events (60 +/- 5 degrees vs 50 +/- 21 degrees , P = .002). The histogram bandwidth was also higher in those with events (185 +/- 37 vs 154 +/- 75, P = .07). All patients with event had a phase SD >or= 50 degrees , while none of the patients with a phase SD < 50 degrees (N = 26) had an event (P = .02).
conclusionsThe severity of LV dyssynchrony by phase analysis in patients with LV dysfunction, and ICD is associated with increased risk of death and appropriate ICD shock; a phase SD < 50 degrees was associated with no events at 1 year.
