Therapeutic hypothermia (TH) is increasingly used in patients presenting with out-of-hospital cardiac arrest (OHCA). Such strategies derive from data that suggest TH may improve survival and attenuate adverse neurological outcomes associated with the cardiac arrest. Consequently, TH has been integrated into various guidelines for the management of OHCA and has become a focussed strategy, particularly in patients with ST-segment elevation myocardial infarction. ⋯ However, even here, trial data robustness has been questioned, with ongoing debate regarding the optimum temperature for managing patients with OHCA and optimal timing of its initiation. More uniform and robust guidelines for the application of TH for patients with OHCA are required, but can only be formulated on appropriately sized robust trials. This review examines the current status of TH.

Current guidelines recommend culprit-only revascularisation (COR) in haemodynamically stable patients with ST-segment elevation myocardial infarction (STEMI) and multivessel (MV) disease. Contrarily, growing body of evidence available from recent randomised controlled trials (RCTs) demonstrates improved outcomes with complete MV-percutaneous coronary intervention (PCI). ⋯ In STEMI and MV disease, complete MV-PCI as compared with non-complete strategy reduces MACE by 41%, driven by a 52% reduction in recurrent MI and 49% reduction in repeat revascularisation.

Multicenter Study Comparative Study
Culprit or multivessel revascularisation in ST-elevation myocardial infarction with cardiogenic shock.
The value of multivessel revascularisation in cardiogenic shock and multivessel disease (MVD) is still not clear. We compared outcomes following culprit vessel or multivessel revascularisation in patients with ST-elevation myocardial infarction (STEMI), cardiogenic shock and MVD. ⋯ This study showed that, compared with culprit vessel revascularisation, multivessel revascularisation at the time of primary PCI was associated with better outcomes in patients with STEMI with cardiogenic shock. Our results support the current guidelines regarding revascularisation in these patients.
