Key takeaways

The trust funds medical and scientific research into heart diseases and their treatment and prevention, and it gives grants only to 501(c)(3) charitable organisations, so a heart-focused project is the core fit.
Its funds must be used within Texas, with a stated preference for Dallas County.
Most of its grants fall between $50,000 and $750,000, with a median of $200,000, so a request in that range is typical, though the filing reports a largest grant of $950,000.
Apply online through the Apply Now link on the trust's detail page, following the Online Help instructions, since email is not accepted, and submit by each May 1.
Repeat giving is strong, with 99% of grant dollars going to organisations it funded in earlier filings, so a first-time applicant should expect a relationship-led process and should make a clear case that its work fits the trust's heart-disease purpose.
