Effects of Hormones on Left Heart Structure and Function with Echocardiography in Acromegaly.
Article in Reviews in cardiovascular medicine, 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
Background: The relationship between growth hormone (GH) and changes in cardiac morphology and function in the current study has not been fully elucidated, and this study aimed to assess the effect of hormonal factors on left ventricular structure and function in acromegaly patients using echocardiography. Methods: We retrospectively analyzed the relationships between various echocardiographic parameters in 117 pre-treatment patients with acromegaly and four hormonal variables: GH, GH nadir during the oral glucose tolerance test (OGTT-GH), insulin-like growth factor-1 (IGF-1), and IGF-1/upper limit of normal (IGF-1/ULN) adjusted for age and sex. Patients were categorized into normal and abnormal subgroups based on interventricular septal (IVS) thickening, left atrial (LA) enlargement, and left ventricular (LV) abnormal LV peak flow velocities E and A (E/A ratios). Furthermore, the hormonal levels within these subgroups were compared. Results: Correlation analysis revealed that IGF-1/ULN was positively associated with IVS thickening and LA enlargement ( Conclusion: IGF-1/ULN is strongly associated with changes in left heart structure and function in acromegaly and serves as a risk factor for these alterations. Thus, monitoring IGF-1/ULN may help predict cardiac changes via echocardiography, suggesting that early clinical management of GH-related levels could prevent early cardiac abnormalities in patients with acromegaly.
