Early neurological rehabilitation management in a stroke patient with persistently and extremely elevated natriuretic peptides: a case report.
Article in Frontiers in medicine, 2026. 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: A marked elevation in N-terminal pro-B-type natriuretic peptide (NT-proBNP) typically suggests heart failure. However, its clinical significance in acute stroke patients without heart failure symptoms remains unclear, often complicating decisions regarding early rehabilitation. When combined with comorbidities such as renal insufficiency, the marked contrast between extremely high NT-proBNP levels and a stable clinical presentation poses a significant challenge for safely initiating rehabilitation. Case description: This report describes a 65-year-old female admitted with an acute left basal ganglia and periventricular cerebral infarction. She had comorbid diabetic kidney disease (stage IV) and renal anemia. Following the stroke, her NT-proBNP level remained persistently elevated above 20,000 pg/mL, yet she was clinically stable with normal cardiac structure and function on resting echocardiography. We interpreted this condition as a state of "cardiovascular reserve exhaustion under multiple hits" and subsequently formulated an individualized rehabilitation strategy based on "cautious initiation and stepwise progression." Through multidisciplinary collaboration, we optimized her volume status and corrected anemia, implementing a stepwise rehabilitation protocol under rigorous monitoring. The patient successfully completed rehabilitation without cardiovascular adverse events and demonstrated neurological improvement. Conclusion: In stroke patients with complex comorbidities, persistently and markedly elevated NT-proBNP levels may reflect a state of "cardiovascular reserve exhaustion" rather than simple heart failure. Under the premise of rigorous multidisciplinary management, optimization of reversible factors, and close monitoring, individualized stepwise early rehabilitation may not necessarily require delay due to this isolated abnormality. This approach suggests that neurological recovery can be promoted while ensuring safety.
