简要总结
PARAMOUNT is a prospective randomized open-label trial testing the hypothesis that a personalized management strategy in symptomatic patients with suspicion of coronary artery disease (CAD), using a CT-based coronary atherosclerotic plaque assessment by AI-enabled quantitative software improves: certainty for diagnosis of CAD, control of CAD risk factors and efficiency of ICA referral with appropriate PCI compared to the usual care strategy based on current AHA/ACC guidelines for care of symptomatic patients with suspicion of CAD.

研究组 & 干预措施
Coronary Plaque-Based Care
Patients randomized to the Coronary Plaque-Based Care arm will undergo CCTA with AI-enabled quantitative assessment of the morphology and composition of coronary atherosclerotic plaque and will receive medical and interventional management informed by CCTA findings and per discretion of the treating physician. All patients will receive a standardized assessment of clinical and risk factor status at baseline and 180 days.
干预措施: Cleerly Labs and Cleerly ISCHEMIA (Device)
Usual Care
Patients randomized to the Usual Care arm will be referred to their usual care providers for standard of care management post stress test findings, possibly including coronary angiography and/or revascularization per the treating provider's recommendation. All patients will receive a standardized assessment of clinical and risk factor status at baseline and 180 days.
结局指标
主要结局
The primary objective of this study is to determine whether a management strategy improves efficiency and effectiveness.
时间窗: Through study completion- an average of 1 year
The primary endpoint is composed of multuple elements, which are to be compared between Coronary Plaque-Based care and the usual care arm, in a hierarchical fashion, using the win ratio approach: 1\. Improved diagnostic certainty of CAD
次要结局
- The secondary objective of the study is to determine whether a management strategy improves patients' experience of chest pain, quality of life, and adherence to medication.(Through study completion- an average of 1 year)
