Malignant Pheochromocytoma Presenting as Acute Coronary Syndrome: A Report of a Rare Case.
Article in Cureus, 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
Pheochromocytomas are rare tumors of the adrenal medulla. The classic presentation for this condition consists of a triad of symptoms: headache, tachycardia, and sweating in an episodic fashion. Rarely, pheochromocytomas are associated with cardiac pathology specifically acute coronary syndrome (ACS) and cardiomyopathy, which is usually attributed to catecholamine excess. They might also present secondary to elevations in blood pressure or arrhythmias. ECG changes are most often encountered as sinus tachycardia. We present a case of previously undiagnosed pheochromocytoma that showed up as ACS across multiple admissions in the setting of significant obstructive coronary artery disease. We aim to contribute to the growing literature reporting this uncommon presentation in order to showcase these cases to the medical audience.
