Coronary CT-Derived FFR-Guided Strategy Versus Medical Therapy

ACCURATE II is a prospective, multicenter, randomized clinical trial comparing the clinical outcome and cost-effectiveness of the two management strategies. CT-FFR-guided invasive treatment strategy versus optimal medical therapy, in management of patients with chronic coronary syndrome. The study is powered to detect if the primary endpoint by the CT-FFR-guided strategy is superior to the medical therapy strategy.
