Targeted nanotherapy to calm inflammation, grow new blood vessels, and prevent scarring after a heart attack

Official title: Targeted Nanotherapy for Inflammation Resolution, Angiogenesis, and Anti-Fibrosis in Acute Myocardial Infarction

Funded at Washington University · NIH-11432693 · Data updated 2026-11-12

A new treatment approach uses engineered secretions from immune cells delivered early after a heart attack to reduce inflammation, promote blood vessel growth, and limit scarring to protect heart function.

Who could benefit from this research

Could help

Ideal participants would be adults who have recently experienced a myocardial infarction and meet the trial's specific eligibility criteria.

Less likely to help

Patients who have contraindications to the therapy or whose condition does not respond to anti-inflammatory or pro-angiogenic strategies may not benefit.

What this research studies

This project aims to deliver an engineered mix from macrophages to the damaged heart quickly after a heart attack. The therapy is designed to reduce harmful inflammation, help new blood vessels form in the injured area, and prevent excessive scar tissue. By combining these three goals in one treatment, researchers hope to support faster and better healing of the heart muscle. The work will be conducted at Washington University in Saint Louis under a physician-scientist-led team.

Why it matters

Potential benefit: If successful, this approach could improve heart function and outcomes after a heart attack by speeding healing and reducing damage.

How similar studies have gone: Previous work in related anti-inflammatory and pro-angiogenic approaches shows promise, but this combined strategy is a novel direction.
