Systemic atherosclerosis assessment using lipoprotein(a) and angioscopy: a prospective study of cholesterol crystal detection

Non-obstructive general angioscopy (NOGA) enables direct, high-resolution visualization of the aortic intimal surface in vivo and allows real-time assessment of plaque morphology and activity. Ruptured aortic plaques (RPs) have been associated with systemic complications, including cerebral infarction, renal dysf...

Association between serum lipoprotein(a) levels and aortic vulnerable plaques assessed by non-obstructive general angioscopy

Background and aims Elevated lipoprotein(a) [Lp(a)] levels are recognized as a genetic risk factor for atherosclerotic cardiovascular disease. Previous coronary imaging studies have linked elevated Lp(a) levels to vulnerable coronary plaque characteristics. However, the relationship between elevated Lp(a) levels and vu...
