Coronary heart disease (CHD) is when your coronary arteries become narrowed by a build-up of fatty material within their walls. These arteries supply your heart muscle with oxygen-rich blood. CHD is sometimes called ischaemic heart disease.
Cardiovascular disease (CVD), also called heart and circulatory disease, is an umbrella name for conditions that affect your heart or circulation. These include high blood pressure, stroke and vascular dementia.
