Which countries run stem-cell trials for Heart Failure & Cardiac Repair?

Country distribution

A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Heart Failure & Cardiac Repair

Cardiac cell studies concentrate in centres with catheterisation labs and imaging cores, since delivery is often intracoronary or intramyocardial. Intravenous infusion in a day clinic is a different intervention from what most registered cardiac trials tested.

Where recruitment is actually open

What travelling for a trial actually involves

Cross-border participation fails on logistics more often than on eligibility: follow-up schedules, local insurance, visa duration and who pays for complications. A site that cannot answer those in writing is not going to enrol you.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

Why trial geography is not a shortlist

The map is drawn by policy and money. Permissive or well-defined regulatory pathways attract registrations and large research budgets attract more still. None of that transfers to the private clinic advertising in the same city, which may operate under no comparable supervision.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (6), 2021 (6), 2022 (6), 2023 (4), 2025 (5), 2026 (6). Activity for this condition spans 2002 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Heart Failure & Cardiac Repair?

Sites are registered in 32 countries; the largest is United States (~38% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

It does not follow. A country can host many trials and still have an unregulated commercial sector selling something quite different to visitors.

Are trial sites and commercial clinics the same thing?

Rarely. Academic trial sites and the private clinics advertising to medical tourists are typically separate organisations with different oversight.
