Readmission in patients with ST-Elevation Myocardial Infarction in 4 age groups ( \u3c45, \u3e45 to \u3c60, 60 to \u3c75, and \u3e75)
The incidence of ST-elevation myocardial infarction (STEMI) among younger adults is increasing due to an increased prevalence of cardiometabolic risk factors. Readmissions after STEMI in young patients could lead to substantial health care costs and a significant burden on health care resources. Although STEMI readmissions are well studied in elderly patients, limited data are available regarding readmissions after STEMI in young patients and the etiologies remain poorly understood. Because younger patients with STEMI have different sociodemographic profiles th;an older patients with STEMI, one would postulate that the risk factors for readmissions in young patients would differ from that reported in the older patients with STEMI. We performed a contemporary nationwide study using the 2016 and 2017 Nationwide Readmissions Database to identify patterns of readmissions after STEMI in the young adult population. Our analysis of the Nationwide Readmissions Database revealed a total of 243,747 hospitalizations for STEMI between 2016 and 2017. Readmission rates demonstrated a steady increase from discharge, increasing to 7.8% at 30 days and 10.3% at 60 days before relatively plateauing at 12.1% at 90 days. Cardiovascular etiologies were the most common cause of readmission (53.6%). After multivariable analysis, development of cardiogenic shock (adjusted odds ratio 1.48, 95% confidence interval 1.11 to 1.97; p = 0.008) and acute renal failure (adjusted odds ratio 1.46, 95% confidence interval 1.14 to 1.87; p = 0.003) during the index admission were associated with significantly higher rates of readmission. In conclusion, close monitoring in young patients who presented with STEMI and concomitant with cardiogenic shock or acute renal failure, and possibly, aggressive therapy during index admission may be needed. However, this population may be heterogeneous and further research is needed
Discontinuation of Long-Term Clopidogrel Therapy Is Associated With Death and Myocardial Infarction After Saphenous Vein Graft Percutaneous Coronary Intervention
Two-year results from Onyx ONE clear in patients with high bleeding risk on one-month DAPT with and without intracoronary imaging.
BACKGROUND: Patients with high bleeding risk (HBR) are often treated with abbreviated dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) to reduce bleeding risk, however this strategy is associated with an increase in ischemic events, especially if the acute PCI result is suboptimal. We compared clinical outcomes among patients with HBR treated with 1-month DAPT who underwent intravascular ultrasound (IVUS)- or optical coherence tomography (OCT)-guided PCI versus those who underwent angiography-guided PCI without intravascular imaging.
METHODS: The Onyx ONE Clear study includes patients with HBR from the Onyx ONE US/Japan and Onyx ONE randomized studies who were treated with the Resolute Onyx zotarolimus-eluting stent. The primary endpoint was the composite of cardiac death (CD) or myocardial infarction (MI) between 1 month and 2 years after PCI. Propensity-score adjustments and matching were performed for differences in baseline and procedural characteristics between groups.
RESULTS: Among the 1507 patients in Onyx ONE Clear, 271 (18.0 %) had IVUS or OCT used during PCI (Imaging-guided group) and 1236 (82.0 %) underwent Angiography-guided PCI (Angio-guided group). Imaging-guided patients were less likely to present with atrial fibrillation, acute coronary syndrome, and left ventricle ejection fraction ≤35 %. Conversely, Imaging-guided patients were more likely to have complex (ACC/AHA type B2/C), longer, and heavily calcified lesions. Between 1 month and 2 years, the composite rate of CD or MI was similar between Imaging-guided and Angio-guided patients (9.9 % vs. 12.4 %, P = 0.33). There was also no difference between groups after adjustment; (P = 0.56). However, CD was significantly lower among Imaging-guided patients (2.7 % vs. 6.1 %, P = 0.048). There were no between-group differences in MI or stent thrombosis. Propensity score matching results were similar.
CONCLUSION: Despite higher lesion complexity, using intravascular imaging guidance for PCI between 1-month and 2-years follow-up had comparable outcomes with angiographic guidance alone in patients with HBR treated with 1-month DAPT. (ClinicalTrials.gov: Identifier: NCT03647475 and NCT03344653).
