Remote ischaemic conditioning for myocardial infarction or elective PCI: systematic review and meta-analyses of randomised trials.

The efficacy of remote ischaemic conditioning in clinical trials of ST-segment elevation myocardial infarction (STEMI) or elective percutaneous coronary intervention is controversial. We aimed to systematically review and meta-analyse whether remote ischaemic conditioning reduces myocardial damage in those patients.
