Atherosclerosis is the gradual hardening and stiffening of arterial walls, leading to the development of 'atherosclerotic lesions', or 'plaques'. Risk factors such as smoking, high-cholesterol, or high blood pressure may contribute to the initiation of a lesion. And over the course of many years, decades even, the arterial wall thickens, and eventually the artery narrows due to the buildup of atherosclerotic plaques. At onset there are no symptoms, but around middle age symptoms could develop, such as coronary artery disease, stroke, peripheral artery disease, or kidney disease.

The Dutch Atherosclerosis Society aims to promote the dissemination and exchange of (clinical) scientific advances in atherosclerosis and vascular biology.
