BACKGROUND: Chronic myocardial ischaemia due to coronary artery stenosis or occlusion has been shown to increase the growth of coronary collateral circulation. Collateralization leads to increased oxygen delivery to the area at risk and hence may reduce ischaemia, prevent infarction and preserve contractile function. However, there is considerable variation among patient subsets in terms of the presence or degree of collateralization. We aimed to evaluate the relationship between obesity and coronary collateral development in patients with ischaemic heart disease.
