In patients with ST-segment elevation myocardial infarction (STEMI), does transfer for percutaneous coronary intervention (PCI) reduce 30-day mortality more than on-site thrombolysis?
Included studies compared transfer for PCI with on-site thrombolysis and reported complete data on survival. Trials that transferred patients for PCI ≤ 6 hours after starting thrombolysis were included. Outcomes were mortality, reinfarction, and stroke, all assessed at 30 days.
MEDLINE, EMBASE/Excerpta Medica, and Cochrane Central Register of Controlled Trials (all 1990 to Apr 2008); and several scientific session abstracts were searched for randomized controlled trials (RCTs). Authors were contacted for additional data. 11 RCTs (n = 5741) met the selection criteria. 4 studies scored > 8 (median score) on a 10-item study quality scale and were considered high quality. 9 studies randomized patients at a community hospital, 1 randomized patients out of hospital, and 1 randomized patients in primary PCI centers, referral hospitals, or out of hospital.
The main results are in the Table.
