Answer

In a study using cardiac magnetic resonance imaging, Ferreira et al found that patients with pheochromocytoma who underwent curative surgery nonetheless continued to demonstrate systolic and diastolic strain, focal fibrosis, and T1 abnormalities, with the last possibly indicating the presence of diffuse fibrosis. According to the investigators, the study’s results suggest more than just hypertensive heart disease at work and that catecholamine toxicity in pheochromocytoma may be responsible for long-lasting myocardial changes.
