Objectives: This study sought to evaluate left ventricular (LV) structure and function in pheochromocytoma and paraganglioma (PPGL) patients before and after curative surgery.
Background: Data on catecholamine-induced effects on LV structure and function in patients with PPGL are limited and conflicting.
Methods: The study evaluated 81 consecutive patients with a PPGL, among whom 66 were evaluated 12 months after tumor removal.
Objective: Structural abnormalities in resistance arteries are a hallmark of patients with hypertension. In hypertensive patients with pheochromocytoma or paraganglioma (PPGL), it is still a matter of debate whether structural vascular changes are because of elevated blood pressure (BP) or to toxic effects of elevated circulating catecholamines. Hence, the aim of our study was to assess whether catecholamine excess and/or elevated BP affect the structure of small retinal arteries in patients with catecholamine-producing tumors.
