Adrenal crisis as a reversible etiology of heart failure with preserved ejection fraction: insights from a case series.
Article in Frontiers 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: Adrenal crisis, characterized by acute cortisol deficiency, is a rare, life-threatening condition that can precipitate cardiovascular collapse and heart failure (HF). Its role in HF with preserved ejection fraction (HFpEF) is underrecognized, particularly in cancer patients receiving therapies that impair adrenal function. This case series examines the clinical features, management, and outcomes of HFpEF induced by adrenal crisis, emphasizing early diagnosis and treatment. Methods: We retrospectively analyzed four patients diagnosed with HFpEF secondary to adrenal crisis between January 2022 and January 2025 at Qingdao Central Hospital and Qingdao Municipal Hospital. Inclusion criteria included clinical evidence of adrenal crisis (low cortisol, hypotension, steroid responsiveness) and echocardiographic confirmation of HFpEF (EF ≥50%). Data on demographics, clinical presentation, laboratory findings, echocardiography, and outcomes were analyzed descriptively. Results: The cohort comprised three males and one female (aged 41-77 years), all with HFpEF (EF 50%-60%). Two presented with myocardial infarction (one NSTEMI, one STEMI), and two had malignancy with adrenal metastasis (renal, lung). Three exhibited hypotension. Initial BNP levels ranged from 518.93-619.13 pg/mL, decreasing to 108.06-287.63 pg/mL pre-discharge after hormone replacement therapy and HF management. Mean EF improved by 1.75% (range: 0%-3%) at one-month follow-up, with BNP further declining to 20.36-177.24 pg/mL. All patients achieved symptom resolution with no recurrence reported. Conclusion: Adrenal crisis is a rare, reversible etiology of HFpEF in patients with diverse underlying conditions, potentially including those with cancer-related adrenal dysfunction or prior therapies. Prompt steroid therapy appears to improve cardiac function and outcomes, suggesting a need for heightened awareness and consideration of adrenal screening in at-risk populations, such as those with malignancy, tuberculosis, or other causes of adrenal insufficiency. Larger studies are needed to confirm these preliminary findings and establish the prevalence of this etiology across different subpopulations.
