Comparison of clinical outcomes in patients presenting with an acute coronary syndrome due to stent thrombosis or saphenous vein graft occlusion and undergoing percutaneous coronary intervention

Early health outcome and 10-year survival in patients undergoing redo coronary surgery with or without cardiopulmonary bypass: a propensity score-matched analysis

OBJECTIVES

To investigate the in-hospital health outcome and 10-year survival in patients undergoing redo coronary surgery with (redo-CABG) or without (redo-OPCAB) cardiopulmonary bypass.

METHODS

A total of 349 redo coronary surgery patients were identified from our registry. Of these, 143 redo-OPCAB patients (40.97%) were compared with 206 redo-CABG patients. To minimize the bias, we also conducted propensity score matching. In Matched Analysis A, 111 redo-OPCAB patients with any type of primary cardiac operation were compared with 111 redo-CABG cases. In Matched Analysis B, 84 redo-OPCAB patients with isolated coronary surgery as their primary operation were compared with 84 redo-CABG patients. We assessed for all 3 analyses a composite of in-hospital mortality, acute kidney injury, stroke and severe low cardiac output requiring intra-aortic balloon pump. In addition, we assessed 1-, 5-, and 10-year survival.

RESULTS

In the unmatched analysis, redo-CABG was associated with higher usage of intra-aortic balloon pump (10 vs 3%, P = 0.01) and composite compared with redo-OPCAB (25 vs 16%, P = 0.06) and similar 10-year survival (67.2 vs 68.5%, log-rank test: P = 0.78). Matched Analysis A showed similar rates of composite (15 vs 21%, P = 0.25) and 10-year survival (65.1 vs 60.8%, log-rank test: P = 0.5). Matched Analysis B showed reduction of the composite (19 vs 8%, P = 0.04), less in-hospital mortality (5 vs 0%, P = 0.13), 4.5 times less need for intra-aortic balloon pump (2 vs 11%, P = 0.02) favouring redo-OPCAB and a similar 10-year survival (71.6 vs 71.7%, log-rank test: P = 0.61).

CONCLUSIONS

Redo-OPCAB surgery is feasible, safe and effective with improved in-hospital outcome and similar 10-year survival compared to redo-CABG.

The impact of recommended percutaneous coronary intervention care on hospital outcomes for interhospital-transferred STEMI patients

BACKGROUND

Timely transfer and percutaneous coronary intervention (PCI) with or without thrombolysis are recommended by the American Heart Association (AHA) to care for ST-segment elevation myocardial infarction (STEMI) patients who present first to a non-PCI-capable hospital. This study was to evaluate the impact on in-hospital mortality of the compliance with guidelines regarding to the time of PCI for patients with STEMI who were transferred to a capable PCI hospital.

METHODS

We used the CArdioVAscular disease Surveillance data from November 2007 to December 2012 for this study. Adult patients who were diagnosed with STEMI and transferred from a primary hospital for PCI were included. Patients who underwent PCI or coronary artery bypass graft surgery in the primary hospital and patients with an unknown emergency department disposition were excluded. The main exposure was the AHA recommendation for reperfusion therapy. We tested the association between compliance with AHA and hospital mortality.

RESULTS

A total of 2078 patients were analyzed, 30.0% of whom were treated in compliance with the guidelines, whereas the remaining 70.0% were not. Thrombolysis was performed in 7.9% and 0.8% (P value < .01) and hospital mortality was 5.0% and 6.8% (P value = .11) in the compliant and violence groups, respectively. The adjusted odds ratios (95% confidence intervals) of the compliant group for hospital mortality were 0.75 (0.46-1.21), respectively. A sensitivity analysis of symptom onset to arrival time was a trend for a beneficial effect in the compliant group.

CONCLUSIONS

Among the patients who were transferred for STEMI care, undergoing PCI as recommended by the AHA was not associated with a mortality benefit, but the patients whose symptom onset to hospital arrival time was within 30 minutes showed an association between compliance and lower mortality.
