RESUMO

AIMS: There are limited data on aspirin (ASA) desensitization for patients with coronary disease. We present our experience with a rapid nurse-led oral desensitization regimen in patients with aspirin sensitivity undergoing coronary angiography. METHODS: This single-center retrospective observational study includes patients with a history of ASA sensitivity undergoing coronary angiography with intent to perform percutaneous coronary intervention (PCI). RESULTS: Between January 2012 and January 2017, 24 patients undergoing coronary angiography for stable coronary disease (7 cases) or acute coronary syndromes (non-ST-segment myocardial infarction [NSTEMI; 8 cases], STEMI [9 cases]) underwent aspirin desensitization having reported previous reactions to aspirin. At initial presentation, previous sensitivity reactions were reported as: mucocutaneous reactions in 17 patients (urticaria in 3 [13%], nonurticarial rash in 6 [25%], angio-oedema in 8 [33%]), respiratory sensitivity in 4 (17%), and systemic anaphylactoid reactions in 3 (13%). Seventeen (71%) patients underwent PCI. Desensitization was acutely successful in 22 (92%) patients and unsuccessful in 2 (8%) patients who both had a single short-lived episode of acute bronchospasm treated successfully with nebulized salbutamol. Fifteen successfully desensitized patients completed 12 months of aspirin; no patient had recurrent hypersensitivity reaction. Aspirin was stopped prior to 12 months in 7 patients (replaced by warfarin [1 case], no antiplatelet or single antiplatelet clinically indicated and clopidogrel chosen [4 cases], patient choice without evidence of recurrent hypersensitivity [1 case], and death due to cardiogenic shock following STEMI [1 case]). CONCLUSION: A rapid aspirin desensitization protocol is safe and effective across a broad spectrum of hypersensitivity reactions and clinical presentations.

RESUMO

BACKGROUND: The PRAMI and CvLPRIT trials support preventive percutaneous coronary intervention (PCI) for multivessel coronary disease found during ST-segment elevation myocardial infarction (STEMI). We assess our real-world experience of the management of multivessel disease identified during primary PCI (PPCI) in a large UK regional centre. PATIENTS AND METHODS: All STEMI patients who underwent culprit-only PPCI during the study period (August 2011 to August 2013) were retrospectively assessed for eligibility to each trial. The two resulting groups were designated as the 'observational' cohorts. Primary outcomes were then determined and compared with the culprit-only revascularisation cohorts from the respective published randomized controlled trials (RCTs). RESULTS: A total of 1143 consecutive cases were presented during the study period. Of these, 343 would have been suitable for inclusion to PRAMI and were included in the 'observational PRAMI' cohort; 196 patients were included in the 'observational CvLPRIT' cohort.The 'observational PRAMI' cohort experienced fewer primary outcome events (13.1 vs. 22.9%), cardiac deaths (0.6 vs. 4.3%) and nonfatal myocardial infarctions (3.5 vs. 8.7%) than the culprit-only PCI PRAMI cohort (n=231); there were significantly more diabetics (P=0.022) and anterior STEMI initial presentations in the culprit-only PCI PRAMI cohort. Primary outcomes were comparable to those of the preventive PCI PRAMI cohort.The 'observational CvLPRIT' cohort showed no significant difference in primary outcomes over 12 months (16.8 vs. 21.2%), but significantly lower all-cause mortality (2 vs. 6.9%) than the culprit-only PCI CvPLRIT cohort (n=146). The 30-day event rates were similar to the preventive PCI arm; the 12-month events were better than the nonpreventive, but not as good as the preventive RCT cohorts. CONCLUSION: Outcomes from culprit-only primary PCI for multivessel disease in patients selected by the RCT criteria from an all-comers population representing real-life experience are better than those published in the two main RCTs. The RCTs may have selected a high-risk population for study exaggerating the benefits of preventive PCI.
