Efficacy of Sacubitril/Valsartan in a Patient With Heart Failure and Impaired Secretion of Atrial Natriuretic Peptide Due to Long-Standing Persistent Atrial Fibrillation.
Article in Cureus, 2024. 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
Atrial natriuretic peptide (ANP) is a circulating hormone released from the atria in response to wall stretch and volume overload in the setting of heart failure. When atrial fibrillation (AF) becomes long-standing persistent, ANP secretion in response to volume overload is impaired due to degenerative changes of the atria. Here, we report a case of heart failure with preserved ejection fraction and impaired ANP secretion due to long-standing AF. N-terminal pro-brain natriuretic peptide (NT-proBNP) level was elevated (269 pg/mL), whereas the increase in ANP level was marginal (46.1 pg/mL), suggesting impaired ANP secretion due to long-standing AF. Valsartan (80 mg/day) was replaced with sacubitril/valsartan (100 mg/day) without changing other medications. Administration of sacubitril/valsartan was effective in improving the patient's symptoms, such as dyspnea and edema, and reducing NT-proBNP level by increasing endogenous ANP level from 46.1 pg/mL to 117 pg/mL in the first four weeks. This case highlights the possibility of impaired ANP secretion in response to volume overload as a predictor of the diuretic effect of sacubitril/valsartan in heart failure. This may lead to individualized treatment for each patient with heart failure based on natriuretic peptide profiles.
