Pheochromocytoma induced hypertension.

Pheochromocytoma (Pheo) is a rare tumor that develops in the core of a chromaffin cell. This article will focus on pheochromocytoma and its affect on the heart. Because the signs and symptoms of a pheochromocytoma are those of the sympathetic nervous system, this tumor is hard to detect and might not be considered early on. In addition, there are many common deferential diagnoses that may lead to a delay of the correct diagnosis of a pheochromocytoma. Uncontrollable hypertension is one of the primary effects of pheochromocytoma. A severe increase in blood pressure (hypertensive crisis) may occur and this can be a life threatening condition that leads to stroke or arrhythmias. African-Americans are disproportionately affected by hypertension and they often go undiagnosed because of a lack of resources or access to care. This tumor is difficult to detect and its effects often mimic many other diagnoses, which often leads to this tumor being a late consideration. The long-term effects of a pheochromocytoma can lead to damage to the heart muscle, congestive heart failure (CHF), increased risk of diabetes, and even death. Nurses need to be aware of the key signs and symptoms of a pheochromocytoma, and to know when testing for this tumor what symptoms should be considered. Patients who suffer from a diagnosis of this tumor need a lot of emotional support and they must follow a strict diet and medication regimen. Nurses can play a vital role in raising awareness in our community about this tumor as well as being a patient advocate.
