There is a lack of evidence for the best management of frail patients with non-ST-elevation myoardial infaarction (NSTEMI). Clinical practice guidelines recommend a routine invasive strategy in NSTEMI in the majority of patients (Roffi Eur Heart 2016). Nevertheless, invasive management is underused in frail and patients with comorbidity (Ekerstad Circulation 2011, Sanchis Mayo Clin Proceed 2011, Graham Can J Cardiol 2013,). Furthermore, frail patients undergoing coronary angiography have lower revascularisation rates than non frail counterparts (Ekerstad Circulation 2011, Graham Can J Cardiol 2013). This may be, in part, a reflection of the more complex coronary artery disease, more frequently presenting left main, three vessel disease or proximal coronary artery disease, which may not be amenable to PCI (Singh Circ Cardiovasc Qualit Outco 2011). However, it is also possible that lower rates reflect an aversion to a perceived risk of the intervention in the frail, whereby those with potential to gain benefit may have been deemed not appropriate for coronary intervention. After PCI or cardiac surgery, frailty and comorbidity are associated with adverse long-term outcomes (Singh CircQualitOutco 2011, SundermanEur J Cardio-thoracic Surgery 2011). Comorbid patients, however, could benefit the most from in-hospital revascularization in NSTEMI (Bauer et al Eur Heart J 2007, Palau Clin Cardiol 2012).
