  • Conflicting data exist regarding the associations between on-site surgical backup and outcomes after primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI). Thus, we sought to assess the impact of such a backup on periprocedural outcomes of primary PCI using data from the Polish National Registry of PCI. From 2014 to 2016 data on 66,707 patients presenting with STEMI undergoing primary PCI from 154 centers were collected. Patients were divided into 2 groups based on the presence of on-site surgical backup. Of 66,707 patients, 15,040 (22.6%) patients were treated in 28 centers with on-site surgical backup. On-site surgical backup was associated with a higher center PCI annual volume (662.4 ± 301.8 vs 1098.7 ± 483.5; p <0.001), but a lower operator PCI annual volume (226.7 ± 126.0 vs 207.8 ± 96.6; p <0.001). The periprocedural mortality (1.60% vs 1.09%; p <0.001) was lower in patients from centers with on-site cardiac surgery and both on-site surgical backup (odds ratio [95% confidence interval], 0.618 [0.517; 0.738]; p <0.001) and the mean number of PCIs by operator per year (odds ratio per 10 [95% confidence interval], 0.990 [0.984; 0.996]; p = 0.001] were independent predictors of periprocedural death. In conclusion, results of our study suggest that periprocedural mortality in patients undergoing primary PCI for STEMI is lower in centers than without on-site cardiac surgical backup. Whether this effect on mortality is attributable to such backup itself and/or whether surgical backup is a marker of overall better medical care and adherence to professional guidelines, this needs clarification in further studies.
