简要总结
The FAST III is a randomized controlled, open-label, multicenter, international, non-inferiority, strategy trial. A total of 2228 participants will be randomized in a 1:1 fashion to either vFFR- or FFR guided revascularization. Patients will be consented prior to the procedure and then followed up to 12 (+1) months after randomization. The primary endpoint is analyzed at 12 months after randomization. Approximately 35 sites in 7 European countries (Netherlands, Ireland, United Kingdom, Germany, Italy, Spain, and France).
详细描述
The FAST III is a randomized controlled, open-label, multicenter, international, non-inferiority, strategy trial of a vFFR guided strategy as compared to a FFR guided strategy to guide coronary revascularization in 2228 subjects with intermediate coronary artery lesions.
Patients are screened for inclusion/exclusion criteria after the indication for coronary catheterization is established. After providing informed consent, patients are enrolled. Randomization is performed in the randomization module of the EDC system with an allocation ratio of 1:1 and stratification by center. The primary endpoint is a composite of all-cause death, any myocardial infarction, or any revascularization at 1 year post-randomization.
All deaths and major cardiovascular events, including the individual components of primary and secondary endpoints are adjudicated by an independent Clinical Events Committee (CEC), using standardized definitions. An independent Data and Safety Monitoring Board (DSMB) will formally review the accumulating data to ensure there is no avoidable increased risk for harm to participants. The FAST III trial is performed in accordance with the Declaration of Helsinki, Good Clinical Practice (GCP), ISO 14155:2020, EC requirements and country specific regulations.

入选标准
- •The patient must be ≥18 years of age
- •Presenting with silent ischemia, stable angina, or non-ST-elevation acute coronary syndrome (NSTE-ACS)
- •Coronary artery disease with at least one native artery in which the stenosis severity is questionable (typically 30-80% stenosis)
- •FFR assessment and vFFR assessment feasible
- •The patient is willing and able to cooperate with study procedures and follow-up until study completion
- •Subject is able to confirm understanding of risks, benefits and treatment alternatives and he/she provides informed consent prior to any protocol-related procedure, as approved by the appropriate Ethics Committee
排除标准
- •ST-elevation myocardial infarction (STEMI) at presentation
- •Cardiogenic shock or severe hemodynamic instability at the time of intervention (heart rate<50 beats per minute, systolic blood pressure <90mmHg) or use of left ventricular assist device
- •Any target vessel with a distal Thrombolysis In Myocardial Infarction (TIMI) flow <
- •Presence of thrombus in intermediate target lesion.
