Secondary Hypertension Causes

Tumors Associated with Hypertension

  • Feocromocitoma, a neuroendocrine tumor, produces catecholamines and causes hypertension in approximately 70% of cases, either stable or paroxysmal, according to the European Society of Cardiology 1, 2
  • Aldosteronismo primario causes between 1% and 11% of primary hypertension cases, characterized by hypokalemia and elevated aldosterone levels, as reported by the European Society of Cardiology 1, 2
  • Hipertensión renovascular is the second most common cause of secondary hypertension, representing approximately 2% of hypertension cases in adults, as stated by the European Society of Cardiology 1

Hypertension Diagnosis and Management

  • The European Society of Cardiology recommends considering other conditions that may cause secondary hypertension, such as feocromocitoma and aldosteronismo primario, in the diagnosis and management of hypertension 1, 2
