Female, age 24, with chronic high blood pressure (hypertension) and autonomic nervous system dysfunction (dysautonomia)

Date of Report

Jun 03, 2021


At 15 years old, the participant began experiencing high blood pressure (hypertension). Over the next 8 years, she was prescribed up to 6 different medications to regulate her high blood pressure. The participant was also found to have autonomic nervous system dysfunction (dysautonomia). She experienced side effects from high blood pressure (hypertensive retinopathy) as well.

The participant has a family history of high blood pressure on both sides of her family, but no one has severe and early-onset high blood pressure like she does.

Treatments for high blood pressure:

  • Amlodipine
  • Amiloride
  • Benazepril
  • Hydralazine
  • Propranolol
Prior Treatments
