An observational study in Coronary Computed Tomography Angiography, Stable Chest Pain and Optimal Medical Therapy, sponsored by Tianjin Chest Hospital. Recruiting at 4 sites in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-03-28.
Sponsored by Tianjin Chest Hospital · Observational
The investigator aims to prospectively enroll patients who were referred for coronary computed tomography angiography (CCTA) for the assessment of stable chest pain (SCP) suspected of obstructive coronary artery disease (CAD). All patients underwent CCTA according to established guidelines and local institutional protocols. The imaging data were evaluated using different image post-processing software to comprehensively analyse anatomical, functional and histological information of coronary. This study will determine if CCTA-based imaging evaluation can provide more informaton to improve clinical management for SCP, including fewer MACE and better decision-making of downstream investigations and therapeutic interventions.
4,857 studies on the registry are indexed under Coronary Artery Disease; 890 are open to participants now.
This study's planned enrollment of 50,000 is above the median of 320 across 1,687 observational studies indexed under Coronary Artery Disease.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Started Jan 2016 (actual). Primary completion is estimated for Jan 2030, 168 months after the start.
Of 634 non-industry observational studies under Coronary Artery Disease, half reached primary completion within 48 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 122. This study's planned 168 months is above that.
Counting every sponsor, half of 759 studies reached it within 40 months; a quarter within 21 and three quarters within 87.
