PREventive Invasive Strategy for Obstructive Coronary Artery Disease With Vulnerable Plaque Evaluated by CoroNary Computed Tomography Angiography-2

Официальное название

A Comparison of Initial Invasive Strategy and Initial Conservative Strategy for the Treatment of Vulnerable Atherosclerotic Coronary Plaques Identified by Coronary CT Angiography

Обзор

The PREVENT-2 trial is to determine whether an initial invasive strategy-consisting of early coronary angiography (CAG) with intent for preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT)-reduces the incidence of the primary composite outcome of cardiac death, target-vessel myocardial infarction (MI), unplanned urgent revascularization, or hospitalization for unstable or progressive angina at 3 years, compared with an initial conservative strategy of optimal medical therapy (OMT) alone, in patients with high-risk vulnerable plaque identified by coronary computed tomography angiography (CCTA).

Вмешательства

• Процедура Initial Invasive Strategy
  Invasive coronary angiography (CAG) within 30 days after randomization, with the intent to perform preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT). For further detailed assessment of vulnerable plaque lesions detected by coronary computed tomography angiography, the use of intracoronary imaging modalities (near-infrared spectroscopy, optical coherence tomography, or intravascular ultrasound) will be strongly recommended.
• Препарат Initial Conservative Strategy
  Optimal medical therapy (OMT) alone, with invasive coronary angiography (CAG) reserved only for failure of optimal medical therapy, defined as recurrent or worsening symptoms despite maximally tolerated medical therapy, or the occurrence of an acute coronary event.
