'''Ischaemic heart disease''' (IHD) is an umbrella term for all conditions characterised by ischaemia of the myocardium. Because this is almost always due to coronary artery [[atherosclerosis]], the term '''coronary artery disease''' (CAD) is virtually equivalent to IHD and they’re often used interchangeably. | <section begin="radiology" />'''Ischaemic heart disease''' (IHD) is an umbrella term for all conditions characterised by ischaemia of the myocardium.

We can distinguish acute and chronic ischaemic heart disease. Acute ischaemic heart disease is referred to as [[acute coronary syndrome]] (<abbr>ACS</abbr>). Chronic ischaemic heart disease is referred to as [[chronic coronary syndrome]] (<abbr>CCS</abbr>) or stable ischaemic heart disease. | We can distinguish acute and chronic ischaemic heart disease.

Cardiac CT can be useful in the evaluation of ischaemic heart disease. Coronary CT angiography is a non-invasive alternative to [[invasive coronary angiography]], used for the diagnosis of coronary artery disease in those at low or intermediate [[pretest probability]]. Those with high pretest probability proceed directly to invasive coronary angiography, as this allows for [[percutaneous coronary intervention]] of any stenoses in the same setting. | Cardiac CT can be useful in the evaluation of ischaemic heart disease.

[[Myocardial perfusion imaging]] (nuclear medicine myocardial perfusion studies) is another modality used for evaluation of ischaemic heart disease. It can detect regions of the myocardium which is hypoperfused during rest or activity. | [[Myocardial perfusion imaging]] (nuclear medicine myocardial perfusion studies) is another modality used for evaluation of ischaemic heart disease.

Screening asymptomatic healthy adults > 40 years with a risk-estimation system like SCORE is recommended. Healthy adults with first-degree relatives with premature (occurring earlier than normal) cardiovascular disease should also be screened. | Screening asymptomatic healthy adults > 40 years with a risk-estimation system like SCORE is recommended.
