Is it possible to regress atherosclerotic lesions with long-term treatment with lipoprotein apheresis?

Abstract

The article presents the up-to-date information on the effect of lipoprotein apheresis (LA) on atherosclerotic lesions. Some studies using modern diagnostic imaging techniques (such as intravascular ultrasound or magnetic resonance imaging) have clearly demonstrated plaque regression. Coronary angiography has also seen reversal or at least slow plaque progression. Plaque regression likely leads to a decrease in the incidence of atherosclerotic cardiovascular events (CVEs). However, this has not yet been fully proven. Recent data indicate that reduction in low-density lipoprotein cholesterol and lipoprotein(a) levels is not a major factor in reducing the incidence of atherosclerotic CVEs in patients undergoing extracorporeal treatment. The most significant risk factors in this case are older age and a greater CVE rate observed before the start of LA, as well as smoking. New studies using modern diagnostic imaging methods in patients receiving LA are necessary.
