Pheochromocytoma with two rare manifestations: Non-ST segment myocardial infarction with normal coronary arteries and blue toe syndrome.

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
We present a 42-year-old man with acute coronary syndrome with normal coronary arteries and blue toe syndrome secondary to pheochromocytoma. The patient's medical history included paroxysmal atrial fibrillation and severe hypertension. He complained of weight loss, headache, excessive sweating, palpitations, and anxiety. He had a dry gangrene on the extremity of the left big toe. Pheochromocytoma was confirmed by extremely elevated normetanephrine and metanephrine serum levels (40 and 61 times the upper limit of normal, respectively). Pheochromocytoma was confirmed. An abdominal computed tomography scan showed a voluminous left adrenal mass. Angio-computed tomography-scan of the lower extremities revealed normal arteries. The patient was treated with an alpha-adrenergic blocker, a beta-adrenergic blocker, and a calcium channel blocker. After discontinuation of the treatment by the patient, he presented with constrictive chest pain, blood pressure crisis, and palpitations. The diagnosis of non-ST segment elevation myocardial infarction was made. Coronary angiography revealed normal arteries. Antihypertensive treatment was reintroduced and a left adrenalectomy was performed without incidents. Ten days after surgery, blood pressure, heart rate, and electrocardiogram were normal. There was a significant improvement in the dry gangrene on the left big toe, 4 days after surgery. Pheochromocytoma may present with unusual clinical manifestations such as acute coronary syndrome and peripheral limb ischemia. Timely diagnosis and management of pheochromocytoma are crucial, as the manifestations in this case disappeared after the pheochromocytoma was surgically removed.
