Abstract Introduction Cardiac computed tomography (CT) use has progressively increased as the preferred initial test to rule out coronary artery disease (CAD) when clinical likelihood is low. Coronary artery calcium (CAC) detected by CT is a well-established marker for cardiovascular risk. However, it is not recommended for diagnosis of obstructive CAD. Absence of CAC, defined as an Agatston score of zero, has been associated to good prognosis despite underestimation of non-calcified plaques. Purpose To evaluate whether zero CAC score could help ruling out obstructive CAD in a safely manner. Methods Observational study based on a prospective database of patients (pts) referred to cardiac CT between 2017 and 2019. Pts with an Agatston score of zero were selected. Results We included 176 pts with zero CAC score and non-invasive coronary angiography performed. The median duration of follow-up was 23.9 months. Baseline characteristics of the population are shown in Table 1. In 117 pts (66.5%), cardiac CT was indicated as part of their chest pain evaluation. Mean age was 57.2 years old, 68.2% were women and only and 9.4% were active smokers. Normal coronary arteries were found in 173 pts (98.3%). Obstructive CAD, defined as ≥50% luminal diameter stenosis of a major vessel, was present in 1/176 (0.6%); while non-obstructive atherosclerotic plaques were found in 2 pts (1.1%). During follow-up, one patient died of out-of-hospital cardiac arrest. None either suffered from myocardial infarction or needed coronary revascularization. Conclusions In our cohort, a zero CAC score detected by cardiac CT rules out obstructive coronary artery disease in 98.3%, with only 1.7% of non-calcified atherosclerosis plaques and 0.6% of major adverse events. Although further research on this topic is needed, these results support the fact that non-invasive coronary angiography could be avoided in patients with low clinical likelihood of CAD and zero CAC score, facilitating the management of the increasing demand for coronary CT and reduction of radiation dose.

Ischaemic Cascade

The inclusion or exclusion of coronary artery disease is important for patient management, both from a diagnostic and prognostic view, as well as from a therapeutic view. Various detection techniques are available, including invasive (coronary angiography) or non-invasive imaging techniques. The techniques can also be divided into anatomical imaging or functional imaging, where anatomical imaging detects coronary atherosclerosis and stenosis (invasive coronary angiography, but also non-invasive coronary angiography—performed with multidetector computed tomography), while functional imaging (nuclear imaging, stress echocardiography, and cardiovascular magnetic resonance) detects ischaemia: the haemodynamic consequences of the atherosclerosis/stenosis. The early phase of atherosclerotic coronary artery disease is often asymptomatic (and anatomical imaging can be used to detect/exclude coronary atherosclerosis), whereas with progression of atherosclerotic disease, symptoms occur related to myocardial ischaemia. Non-invasive imaging can facilitate in the detection of both early (asymptomatic) and more advanced (symptomatic, ischaemic) coronary artery disease. The pathophysiological cascade of cardiac abnormalities that occur once ischaemia is induced is referred to as the ischaemic cascade. The ischaemic cascade consists of chronological development of perfusion abnormalities, followed by diastolic dysfunction, then systolic dysfunction, and finally electrocardiographic abnormalities. In this chapter, the variety of the different non-invasive imaging techniques to assess the different phases of the non-ischaemic part and the ischaemic part (ischaemic cascade) of coronary artery disease are described.

Artery Disease

Single coronary artery (SCA) is a very rare coronary anomaly. The accurate diagnosis of the entity requires multimodality imaging of the coronary anatomy. SCA is often incidentally diagnosed when patients are investigated for symptoms of suspected coronary artery disease with invasive or non-invasive coronary angiography. There are no established diagnostic electrocardiographic or echocardiographic criteria to identify the presence of SCA, which makes the diagnosis a far-reaching fruit. We present a young male patient presenting with a non-ST elevation myocardial infarction. He was found to have SCA on invasive coronary angiography, which was subsequently confirmed by CT coronary angiography.
