Abstract Objective To assess the anticoagulant therapy for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in China and to offer the rationale for establishing reasonable strategies to improve the prognosis of NSTE-ACS. Methods A total of 1,502 patients with NSTE-ACS were recruited from 28 third-grade hospitals distributed in 14 provinces and cities in China from December 2009 to December 2011. The strategies for diagnosis and treatment, decided by each hospital respectively, were used for further analysis and comparison of medication, percutaneous coronary intervention (PCI), and end points for efficacy and safety assessment at 9 and 30 days following PCI. Results A lower incidence rate (P < 0.05) was noted for efficacy and safety in patients with unstable angina (UA) than those with non-ST-segment elevation myocardial infarction (NSTE-MI). The prescription rate of unfractionated heparin (UFH), low-molecular-weight heparin (LMWH), fondaparinux, PCI, and single medication was 0.61%, 66.42%, 30.61%, 69.64%, and 70.74%, respectively. Conclusion Compared with NSTE-MI, UA is featured with better prognosis, less severity, and different outcome. However, in clinical practice, the therapies for NSTE-MI and UA show no differences, which deserves great attention. In China, the most common anticoagulant therapies for NSTE-ACS are single medication, mainly based on LMWH and PCI.

Background/Aims The primary percutaneous coronary intervention pathway for patients experiencing an ST segment elevation acute coronary syndrome excludes patients with aVR ST elevation. These patients are treated on the non-ST segment elevation acute coronary syndrome pathway, which means that they have a coronary angiogram +/− intervention during their inpatient stay. Patients with non-ST segment elevation acute coronary syndrome have worse outcomes nationally. As such, research is required to demonstrate areas for improvement. This article examines the association between aVR ST segment elevation on the electrocardiogram and significant left main stem, proximal left anterior descending, or 3-vessel coronary artery stenosis in acute coronary syndrome to establish whether the primary percutaneous coronary intervention pathway should be redesigned. Methods Existing literature was searched, and relevant studies were considered and evaluated. Data were collected within local NHS Trusts on patients who had aVR ST segment elevation on the electrocardiogram. The data were analysed, and the findings were compared and synthesised with the literature. Results The study demonstrated a relationship between aVR ST segment elevation and significant disease. However, because of the numbers involved, analysis to demonstrate statistical significance was not possible, with the exception of aVR ST segment elevation and left main stem coronary artery, left anterior descending coronary artery and triple vessel disease, where p<0.05 in the population with left main stem coronary artery occlusion +/− other disease. The study demonstrated that aVR ST segment elevation should be treated as an ST segment elevation acute coronary syndrome equivalent, as it is a high-risk finding. These patients should go immediately to the cardiac catheter laboratory for a primary percutaneous coronary intervention. Conclusion The need for a change in the primary percutaneous coronary intervention pathway was established.

Abstract Background The association between baseline hemoglobin A1c (HbA1c) levels before the percutaneous coronary intervention and bleeding is unclear in patients with non-ST-segment elevation acute coronary syndrome. Purpose To investigate the association between baseline HbA1c levels before the percutaneous coronary intervention and bleeding in patients with non-ST-segment elevation acute coronary syndrome. Methods This observational cohort study enrolled 6,283 consecutive patients with non-ST-segment elevation acute coronary syndrome, from 1 January 2010 to 31 December 2014. Based on baseline HbA1c levels, the patients were divided into the HbA1c &lt;7% group (n=4,740) and the HbA1c ≥7% group (n=1,543). The primary outcomes are major bleeding events (BARC grades 3–5) and all-cause death during follow-up. Results Of the patients who were enrolled, 4,705 (74.9%) were male and 2,143 (34.1%) had a history of diabetes mellitus, with a mean (SD) age of 64.13 (10.32) years. Median follow-up duration was 3.21 years. Compared with HbA1c &lt;7% patients, the risk of major bleeding events and all-cause was both higher in HbA1c ≥7% patients (major bleeding: adjusted hazard ratio, 1.62; 95% confidence interval, 1.04–2.53; P=0.032; all-cause death: adjusted hazard ratio, 1.26; 95% confidence interval, 1.03–1.55; P=0.027). The result of the subgroups analyses was consistent with the primary analyses. Conclusions Higher baseline HbA1c levels before percutaneous coronary intervention was associated with an increase in bleeding risk in non-ST-elevation acute coronary syndrome patients. This study suggests that the HbA1c levels should be taken into account for the prolonged antithrombotic strategies of non-ST-elevation acute coronary syndrome patients. Figure 1.
