What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether a new ultra-high resolution CT scanner is better than a standard CT at finding blocked arteries in the heart. About 140 adults with suspected coronary heart disease will get one scan, and the images will be compared to the usual method (catheterization). The goal is to see if the sharper images help doctors detect serious blockages more accurately.

Inclusion Criteria: * Patients aged 21-85 years * Clinical history suggestive of CHD who are referred by their primary cardiologist for further evaluation via Computed tomography angiography (CTA) will be asked to participate. * Women of child bearing potential must demonstrate a negative pregnancy test within 24 hours of the study CTA. * Ability to understand and willingness to sign the Informed Consent Form.
