How patients and doctors value different outcomes after coronary stent procedures
A Preference Study Comparing the Components of Composite Endpoints for Healthcare Providers and Patients With CAD
Xijing Hospital · NCT07378137
This project asks patients who had a coronary stent (PCI) and the doctors who treat them to rate how important different possible outcomes are to see if their priorities match.

What this trial studies
This observational questionnaire study invites adults with acute or chronic coronary syndrome who have undergone PCI and healthcare providers who treat coronary artery disease to rate the relative importance of individual events that commonly make up composite endpoints. Participants complete structured preference questionnaires asking them to weight or rank outcomes such as death, myocardial infarction, repeat revascularization, and bleeding. The study then compares patient and provider weights to identify differences in perceived importance across components. Findings are intended to inform whether weighted composite endpoints should better reflect patient priorities in future clinical trials.
Who should consider this trial
Good fit: Ideal participants are adults (aged 18 or older) with acute or chronic coronary syndrome who have undergone PCI and can understand and complete the preference questionnaire, as well as healthcare providers who treat CAD.
Not a fit: People under 18 or those with cognitive impairment or who cannot complete the questionnaire are excluded and unlikely to benefit from participating.
Why it matters
Potential benefit: If successful, results could help clinical trials report composite outcomes that reflect patients' priorities, making results more useful for patient decision-making and care.
How similar studies have performed: Previous methodological work has proposed weighted composite endpoints and small surveys have suggested differences between patient and clinician priorities, but no broadly accepted weighting standard exists.
