Reversible Pseudo-Amyloid Strain Pattern in Acute Hypertensive Cardiomyopathy.
Article in JACC. Case reports, 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
backgroundAcute hypertensive cardiomyopathy can transiently reproduce imaging features typically associated with infiltrative cardiomyopathies, including an apical-sparing strain pattern. CASE SUMMARY: A middle-aged patient presented with severe hypertension, pulmonary edema, concentric left ventricular wall thickening, and an apical-sparing global longitudinal strain pattern suggestive of cardiac amyloidosis. Cardiac magnetic resonance imaging demonstrated normal native T1 values, preserved extracellular volume, and only minimal nonspecific late gadolinium enhancement, findings incompatible with amyloid light-chain or transthyretin amyloidosis. With rapid afterload reduction, wall thickness, global longitudinal strain, and the strain distribution normalized, confirming load-dependent dysfunction. DISCUSSION: Acute elevations in afterload can disproportionately impair basal longitudinal fibers, producing a reversible pseudo-amyloid strain pattern that may resemble infiltrative disease on initial assessment. TAKE-HOME MESSAGES: Apical sparing can occur in acute hypertensive cardiomyopathy. Load-dependent basal dysfunction may mimic amyloid patterns. Rapid reversibility aids diagnostic distinction.
