Which countries run stem-cell trials for Arterial Hypertension?

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 Arterial Hypertension

Cardiovascular cell studies sit in centres with ambulatory monitoring and event-adjudication capacity. Because hypertension is treatable with inexpensive generics almost everywhere, a clinic marketing cell infusions for blood pressure to international patients is competing with a drug that costs pennies and has outcome data.

Where recruitment is actually open

What travelling for a trial actually involves

Travelling to a trial site is not like booking a treatment package. Sites enrol people they can follow up, which usually means repeated visits over months, local imaging or bloods, and an emergency route if something goes wrong. Ask about all three before booking anything.

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

Trial locations follow regulation, funding and sponsor headquarters, not clinical quality. Countries with clear conditional pathways for advanced therapies and large public research budgets register more studies. A country appearing here also says nothing about whether commercial clinics there operate under the same oversight as the registered trials.

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: 2023 (1), 2024 (3), 2025 (2), 2026 (1). Activity for this condition spans 2001 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Arterial Hypertension?

Sites are registered in 13 countries; the largest is United States (~43% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

No. Registration volume reflects the research and regulatory environment, not the quality of care a private clinic there will provide.

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.
