Global appraisal of the patient’s condition & risk Use of a standard check list (adapted to each institution) – Clinical information, psychological profile and culture – Co-morbid factors – Possible interference with DAPT – Biochemical markers – LV and valvular function – Testing for ischemia/viability – Coronary angiography Use of risk scores
Global appraisal of the patient’s condition & risk Why using Risk scores in day-to-day practice? – Physicians are risk-averse and driven by personal experience – High-risk patients are denied the potentially large benefit of invasive therapies, be it with increased risk – Using risk scores helps reducing bias and targeting treatment strategies to personnalized needs – Adherences to guidelines increases, with subsequent improvement in outcomes

Joint 2010 ESC - EACTS Guidelines on Myocardial Revascularisation Calculating GRACE Risk Score
SpecificationClassLevel An invasive strategy is indicated in patients with: GRACE score > 140 or at least one high-risk criterion, recurrent symptoms, inducible ischaemia at stress test. IA An early invasive strategy ( 140 or multiple other high-risk criteria. IA A late invasive strategy (within 72 h) is indicated in patients with GRACE score < 140 or absence of multiple other high-risk criteria but with recurrent symptoms or stress-inducible ischaemia. IA Patients at very high ischaemic risk (refractory angina, with associated heart failure, arrhythmias or haemodynamic instability) should be considered for emergent coronary angiography (< 2 h). IIaC An invasive strategy should not be performed in patients: at low overall risk, at a particularly high-risk for invasive diagnosis or intervention. IIIA Recommendations for revascularisation in NSTE-ACS

ACEF score = [Age/Ejection Fraction (%)] + 1 (if Creatinine > 2 mg/dL). Recommended risk stratification scores to be used in candidates for PCI or CABG ●For PCI, SYNTAX score emerges as preferred score to quantify complexity of CAD, but needs to be tested in other trials. ●For CABG, both EuroSCORE and STS score are well validated, mostly based on clinical variables. ●STS score is undergoing periodic adjustment which makes longitudinal comparisons difficult.
