Peripheral artery disease risk factors: A focus on lipoprotein(a).

There is a well-established and strong link between high lipoprotein(a) concentration and coronary heart disease, but the evidence regarding peripheral artery disease and carotid atherosclerosis is not as conclusive. This review aims to summarize the relationships between lipoprotein(a), peripheral artery disease and carotid atherosclerosis, in order to try to understand the weight of lipoprotein(a) in determining the development, progression and any complications of atherosclerotic plaque at the carotid and peripheral artery level. There is currently no effective therapy to reduce lipoprotein(a) concentration, but understanding its significance as a vascular risk factor is the starting point to then explore (when effective therapies become available) if there is the possibility, even in patients with peripheral artery disease and carotid atherosclerosis, to achieve better control of the residual vascular risk that is ultimately induced by lipoprotein(a).
