Exosome treatment may curb heart scarring after heart attacks

MedicalXpress | يول 30, 2026

Many people who survive a heart attack will later develop heart failure due to the scarring that occurs as the heart heals. Researchers at Uppsala University are now presenting a new type of biological treatment that is administered directly into the damaged blood vessel and stimulates healing. In the study, they also demonstrate how a new PET (Positron Emission Tomography) method can be used to identify patients with ongoing scarring and, ultimately, enable personalized treatment.
