Strategical categorization of coronary interventions during COVID-19 pandemic

Clinical condition	EMERGENT (do not postpone)	URGENT (perform within days)*	LOWER PRIORITY (perform within <3 months)*	ELECTIVE (may be postponed >3 months)
Ischaemic heart disease	STEMI NSTE-ACS in very high risk and high risk patients Cardiogenic shock	NSTE-ACS in intermediate risk patients Unstable angina Left main PCI Last remaining vessel PCI Decompensated ischaemic heart failure Angina pectoris class IV CABG in patients with NSTE-ACS unsuitable for PCI	Advanced CAD with angina class III or NYHA III symptoms Staged PCI of non-IRA in STEMI in patients with haemodynamic stability and without >90% lesions in proximal segments of major epicardial coronary arteries Proximal LAD PCI	CTO interventions CCS with angina class II or NYHA II symptoms
Acute/chronic heart failure	•Mechanical circulatory support for cardiogenic shock (<65 years)	•Urgent heart transplant	•LVAD

^*Timing might be affected by overwhelming demand on resources in the setting of a COVID-19 pandemic.

CABG, coronary artery by-pass grafting; CCS, chronic coronary syndromes; CTO, chronic total occlusion; IRA, infarct related artery; LAD, left anterior descending; LVAD, left ventricle assist device; LVEF, left ventricular ejection fraction; NSTE-ACS, non-ST-segment elevation acute coronary syndrome; NYHA, New York Heart Association; PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction.
