Answer

Many cardiac manifestations are associated with pheochromocytomas. [26] Hypertension is the most common complication. Cardiac arrhythmias, such as atrial and ventricular fibrillation, may occur because of excessive plasma catecholamine levels. Other complications include the following:

  • Myocarditis
  • Signs and symptoms of myocardial infarction [27]
  • Dilated cardiomyopathy
  • Pulmonary edema: Either of cardiac or noncardiac origin
