‘An amazing relief’: implant offers hope for those with refractory angina
Summary
A small implant called a coronary sinus reducer (CSR) has helped people with refractory angina, a severe form of chest pain linked to heart disease. A large study found that 75% of patients had less chest pain within six months after getting the implant, which improves blood flow to parts of the heart with low oxygen.Key Facts
- Cristian Jensen, who had severe angina, received the implant in 2021 and now experiences fewer attacks and less fear related to his condition.
- Angina causes chest, neck, shoulder, jaw, or arm pain due to reduced blood flow to the heart muscle.
- Refractory angina is chest pain that continues despite treatments like drugs, stents, and bypass surgery.
- The implant is an hourglass-shaped device placed using keyhole surgery through the neck vein.
- The implant works by narrowing a heart vein to redirect blood flow to poorly oxygenated heart muscle.
- The study observed 491 patients between 2014 and 2024 at 19 hospitals in England and Scotland, with 474 receiving the implant.
- About 75% of patients experienced a significant reduction in chest pain within six months after the implant.
