Angiographic disease progression and residual risk of cardiovascular events while on optimal medical therapy observations from the COURAGE trial
Acute Coronary Syndrome
Coronary Artery Disease
Lesions originally <50% DS were index lesions in one third of patients referred for symptom-driven repeat angiography, but represented <4% of all such lesions. Nonrevascularized lesions originally ≥50% DS were more often index lesions in OMT-only patients, but still represented a minority (<25%) of all such lesions. These findings underscore the need for improved therapies to arrest plaque progression and reliable strategies for selecting stenoses warranting PCI.
