Table 1: High Thrombotic Risk ‘Coronary–Vascular–Disease’ Algorithm.

Assessment of High-risk Chronic Coronary Syndrome
C = CORONARY	V = VASCULAR	D = DISEASE
Prior coronary event High-risk coronary anatomy* Documented multi-vessel coronary disease†	Established peripheral artery disease‡ Cerebrovascular disease§	Diabetes on treatment eGFR <60 mg/min/1.73 m2 Micro- and macro-albuminuria Heart failure due to coronary artery disease

The presence of any single factor listed would indicate high thrombotic risk in a chronic coronary syndrome patient. Presence of multiple factors would indicate even higher risk of thrombosis in the patient. *Left main PCI, bifurcation PCI, multivessel PCI, more than three stents. †Documented by CT cardiac angiography, severe ischaemia on functional stress test, prior PCI, CABG or bypass. ‡Claudication or prior peripheral intervention, carotid stenosis >50%, mesenteric artery disease, renal artery stenosis. §Ischaemic stroke or transient ischaemic attacks due to atherosclerosis. CABG = coronary artery bypass graft; eGFR = estimated glomerular filtration rate; PCI = percutaneous coronary intervention.
