Can aggressive meds shrink hidden plaque in women's arteries?
NCT ID NCT05035056
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 191 women with non-obstructive coronary artery disease (plaque that doesn't block arteries). Researchers used CT scans to measure whether intensive medical therapy (like statins and blood pressure drugs) reduced plaque more than usual care. The goal was to see if better plaque control also improves symptoms like chest pain. The study is complete and aims to understand how intensive treatment helps women with this condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intensive medical therapy (statins, aspirin, ACE inhibitors, etc.)
- What this could lead to
- If successful, this could show that intensive medical therapy reduces plaque buildup and improves symptoms in women with non-obstructive coronary artery disease.
- What could go wrong
- This is a completed observational analysis of a prior trial, not a new treatment test. Results may not apply to all women or lead to immediate changes in care.

Who is studied
This ancillary sub-study will draw 204 patients from the WARRIOR patient group (4422 women), who have undergone a baseline CTA as part of the WARRIOR trial. From this group, 204 patients most compliant with the medication regimen (intensive medical therapy (IMT) with aspirin, statin, angiotensin-converting enzyme inhibitor, and/or angiotensin receptor blocker) vs. usual care (UC) recommended in their treatment groups will undergo a follow-up coronary CTA.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * In addition to the inclusion criteria of the WARRIOR trial, only women who meet the following criteria will undergo final CTA at the same sites where they are screened and enrolled. * Initial CTA with excellent or good image quality-defined as images where we are able to clearly identify the atherosclerotic plaque. Based on our preliminary assessment, we expect 90% of studies to be included. * Measurable plaque with total plaque volume \>0mm3; women without significant plaque will not receive additional radiation, and we can detect measurable changes in plaque burden and plaque composition. Exclusion Criteria: * In addition to exclusion criteria of the parent WARRIOR trial, key exclusion criteria are: * Non-adherent with IMT. The parent trial is already powered for non-adherence. In our ancillary trial we have built in an exclusion, from final analysis, of an additional 30% who may be nonadherent with IMT or UC.
