Octreotide therapy in patients with a left ventricular assist device and bleeding gastrointestinal angiodysplasias.
Article in The American journal of the medical sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAngiodysplasias commonly develop in patients with left ventricular assist devices (LVADs) and often bleed recurrently. Whether octreotide reduces the burden of angiodysplasia or the frequency of bleeding in these patients is controversial. Hence, we aimed to study the effect of long-acting octreotide on angiodysplasia bleeding in LVAD patients.
methodsBetween May 2012 and December 2023, 65 patients with LVAD and angiodysplasia were identified at our tertiary care medical center. Of those, 33 patients received octreotide therapy. Complete clinical data were abstracted from the medical record, and outcomes pre and post octreotide therapy were examined.
resultsIn 33 patients (61 ± 8 years old and 9 women) who received long-acting octreotide for recurrent angiodysplasia bleeding that failed to respond to endoscopic therapy, the small intestine was the most common site involved. Prior to octreotide, patients received an average of 2.0 ± 3.0 units/month of PRBCs over an average of 16 months, which decreased to 0.5 ± 0.8 units/month over 31 months on therapy. Over an average period of 31 months on octreotide therapy, GI bleeding events and the number of endoscopic therapies per month decreased from 0.4 ± 0.2 to 0.1 ± 0.2 (p = 0.01) and from 0.7 ± 0.8 to 0.1 ± 0.2 (p = 0.001), respectively. Finally, hemoglobin and hematocrit levels increased over the 31 month follow-up period while on octreotide therapy.
conclusionIn patients with an LVAD and recurrent angiodysplasia bleeding, octreotide appeared to reduce the number of GI bleeding events, the need for GI endoscopic therapies, and the frequency of PRBC transfusions.
