ImportanceIn patients with multivessel coronary artery disease (CAD) presenting with ST-segment elevation myocardial infarction (STEMI), complete revascularization reduces major cardiovascular events compared with culprit lesion–only percutaneous coronary intervention (PCI). Whether complete revascularization also improves angina-related health status is unknown.ObjectiveTo determine whether complete revascularization improves angina status in patients with STEMI and multivessel CAD.Design, Setting, and ParticipantsThis secondary analysis of a randomized, multinational, open label trial of patient-reported outcomes took place in 140 primary PCI centers in 31 countries. Patients presenting with STEMI and multivessel CAD were randomized between February 1, 2013, and March 6, 2017. Analysis took place between July 2021 and December 2021.InterventionsFollowing PCI of the culprit lesion, patients with STEMI and multivessel CAD were randomized to receive either complete revascularization with additional PCI of angiographically significant nonculprit lesions or to no further revascularization.Main Outcomes and MeasuresSeattle Angina Questionnaire Angina Frequency (SAQ-AF) score (range, 0 [daily angina] to 100 [no angina]) and the proportion of angina-free individuals by study end.ResultsOf 4041 patients, 2016 were randomized to complete revascularization and 2025 to culprit lesion–only PCI. The mean (SD) age of patients was 62 (10.7) years, and 3225 (80%) were male. The mean (SD) SAQ-AF score increased from 87.1 (17.8) points at baseline to 97.1 (9.7) points at a median follow-up of 3 years in the complete revascularization group (score change, 9.9 [95% CI, 9.0-10.8]; P < .001) compared with an increase of 87.2 (18.4) to 96.3 (10.9) points (score change, 8.9 [95% CI, 8.0-9.8]; P < .001) in the culprit lesion–only group (between-group difference, 0.97 points [95% CI, 0.27-1.67]; P = .006). Overall, 1457 patients (87.5%) were free of angina (SAQ-AF score, 100) in the complete revascularization group compared with 1376 patients (84.3%) in the culprit lesion–only group (absolute difference, 3.2% [95% CI, 0.7%-5.7%]; P = .01). This benefit was observed mainly in patients with nonculprit lesion stenosis severity of 80% or more (absolute difference, 4.7%; interaction P = .02).Conclusions and RelevanceIn patients with STEMI and multivessel CAD, complete revascularization resulted in a slightly greater proportion of patients being angina-free compared with a culprit lesion–only strategy. This modest incremental improvement in health status is in addition to the established benefit of complete revascularization in reducing cardiovascular events.
Adding clopidogrel to aspirin for 3 months after transcatheter atrial septal defect (ASD) closure results in a lower incidence of new-onset migraine attacks. However, the outcomes at 6-to 12-month follow-up (after clopidogrel cessation at 3 months) remain largely unknown.OBJECTIVE To assess the incidence of migraine attacks at 6-and 12-month follow-up after transcatheter ASD closure.
DESIGN, SETTING, AND PARTICIPANTSThis prespecified analysis of a randomized, double-blind clinical trial included patients with no prior history of migraine undergoing ASD closure from 6 university hospitals in Canada from December 2008 to November 2014. Patients were followed up at 3, 6, and 12 months, and a migraine headache questionnaire was administered at each time. Analysis began June 2019.INTERVENTIONS Patients were randomized (1:1) to receive dual antiplatelet therapy (aspirin plus clopidogrel; n = 84) vs single antiplatelet therapy (aspirin plus placebo; n = 87) for 3 months following transcatheter ASD closure. After 3 months, only single antiplatelet therapy (aspirin) was pursued.
MAIN OUTCOMES AND MEASURESIncidence and severity of migraine attacks at 6-and 12-month follow-up.
RESULTSThe mean (SD) age of the study population was 38 (12) years, with 106 women (62%). A total of 27 patients (15.8%) had new-onset migraine attacks within the 3 months following ASD closure (8 of 84 [9.5%] vs 19 of 87 [21.8%] in the initial clopidogrel and placebo groups, respectively; P = .03). After cessation of clopidogrel and aspirin monotherapy, the percentage of patients with migraine attacks decreased over time, with 8 (4.7%) and 4 patients (2.3%) continuing to have migraine attacks at 6 and 12 months, respectively (vs 3 months: P < .001). The severity of migraine attacks progressively decreased over time; no moderate or severe attacks occurred at 6 and 12 months (vs 3 months: P < .001). There were no differences between groups in the rate of migraine attacks at 6 months (initial clopidogrel group: 2 of 84 [2.4%]; initial placebo group: 6 of 87 [6.9%]; P = .28) and 12 months (initial clopidogrel group: 3 of 84 [3.6%]; initial placebo group: 1 of 87 [1.1%]; P = .36) after ASD closure. Only 2 patients (1.2%; 1 patient per group) presented with new-onset migraine attacks after 3 months.CONCLUSIONS AND RELEVANCE New-onset migraine attacks after ASD closure improved or resolved spontaneously within 6 to 12 months in most patients. No significant rebound effect was observed after clopidogrel cessation at 3 months. These results demonstrate a low rate of migraine events beyond 3 months following transcatheter ASD closure and support the early discontinuation of clopidogrel therapy if administered.
The routine use of entire radiological trauma series in alert pediatric patients with a normal physical examination has a very low yield. In these children, the localizing signs and symptoms can help us in determining the specific radiological examination to be utilized.
