Global Heart Hub Patient Voices: Daniela Machado

Introducing a new series from Global Heart Hub, sharing inspiring Patient Voices from our Affiliate community. We’re delighted to share Daniela’s story. Daniela joined Global Heart Hub as a Patient Affiliate in 2025.

Daniela Machado was born in Portugal and now lives in England. She is a neonatal nurse, author and patient advocate.

Having been born with a common congenital heart defect, Daniela lived a normal life with regular cardiology appointments until 2019 when her life changed completely. Daniela developed a serious, often fatal, infection.

Daniela’s experience with cardiovascular disease was sudden, life-altering and deeply humbling. She underwent emergency open-heart surgery lasting six and a half hours. Her surgeons repaired her tricuspid valve and ventricular septal defect. “I spent 52 days in the hospital,” says Daniela.

“There is a particular vulnerability in heart illness. The heart feels symbolic as much as physical: it is life, rhythm, continuity. When something threatens it, everything feels uncertain. I remember the fear, not just of pain or procedures, but of the unknown. The waiting. The silence between medical updates. The way your body no longer feels entirely yours.”

Daniela needed dialysis treatment for kidney failure, a connected condition of cardiovascular disease. “When I started dialysis, I truly thought my life had ended. When you’re facing it at a younger age, there’s an added layer of disbelief. You look to the dialysis machine or the outpatient clinic and wonder how you ended up here so soon. There can be isolation — friends may not always understand, and you may feel as though you’ve stepped onto a different timeline from everyone else.”

Thank you, Daniela, for sharing your story.
