Long-term follow-up of antithrombotic management patterns in patients with acute coronary syndrome in China.

ABSTRACT:

Objective

To describe the long-term antithrombotic management patterns (AMPs) and clinical outcomes of Chinese patients with acute coronary syndrome (ACS).

Methods

This was an observational, multicenter, longitudinal cohort extension study of Chinese patients who had completed the EPICOR Asia 2-year follow-up study post-hospitalization for an ACS event. Changes in AMP and clinical outcomes for up to 5 years post-ACS event were evaluated.

Results

Overall, 2334 patients with ACS were enrolled at 49 sites. The mean age was 61.6 years and 76.3% were men. By study end, 2093 patients completed the 3-year follow-up. At baseline (2 years post-ACS event), 72.4% of patents received one antiplatelet (AP) medication, with aspirin being the preferred one. A small proportion of patients (21.5%) was treated with two or more APs (2+ AP), and even fewer patients (6.1%) did not receive any AP medication at baseline. Upon study completion, the proportion of patients without AP therapy increased to 13.6%, while the percentage of patients on one AP and 2+ AP decreased to 69.3% and 17.1%, respectively. Numerically, a higher incidence of clinical events (composite of all-cause mortality, myocardial infarction, stroke) was observed for the 2+ AP (13.2%) subgroup than for the no AP (10.5%) and one AP (8.6%) subgroups. Furthermore, the 2+ AP subgroup exhibited the greatest number of bleeding events, outpatient visits, and hospitalization rates. Unlike myocardial infarction or stroke, bleeding events prompted an adjustment in AMP.

Conclusion

Most patients in China received at least one AP medication up to 5 years after an ACS event.

Project description:BackgroundAcute coronary syndrome (ACS) is associated with emergency hospitalizations, and there are limited real-world data on clinical outcomes in post-ACS Asian patients. This article presents data on the Indian subgroup from the Long-term Follow-up of Antithrombotic Management Patterns in Acute Coronary Syndrome Patients in Asia (EPICOR-Asia) study.MethodsEPICOR included patients with ACS [ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), or unstable angina (UA)]. The study had two phases: acute phase and follow-up phase. The primary objective was to describe short- and long-term antithrombotic management patterns.ResultsEPICOR-India enrolled 2468 patients (STEMI-1482; NSTEMI-562; and UA-424). Cardiovascular risk factors were present in 1362 (55.2%) patients. Prehospital care was received by 879 (35.6%) patients, and the median time from the symptom onset to the first medical attention was 3 h (0.08, 100.33). The most common drug regimen prescribed during the acute phase was ≥2 antiplatelet agents + anticoagulants with no glycoprotein IIb/IIIa inhibitors and at discharge were aspirin + clopidogrel. About 78.8% of patients were discharged on dual antiplatelet therapy (DAPT) and 16%, on single antiplatelet therapy (SAPT). At 23 months after discharge, 55.6% were on DAPT, while 16.4% were on SAPT. Postdischarge outcomes at 2 years included death in 165 (6.7%) patients, composite events of death, myocardial infarction (MI), or ischemic stroke in 182 (7.4%) patients, and bleeding events in seven (0.3%) patients.ConclusionThis study showed a gap between international recommendations and implementation for managing ACS in Indian patients. Most of the patients prefer to undergo invasive management instead of non-invasive therapy. At the end of the 2-year follow-up, more than half of the population was receiving DAPT, with most patients on receiving a combination of aspirin and clopidogrel. The mortality along with composite events of death, MI, or ischemic stroke was highest for patients with NSTEMI.

Project description:BackgroundRisk stratification of patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) is an important clinical method, but long-term studies on patients subjected to all-treatment strategies are lacking. Therefore, the aim was to compare several established risk scores in the all-treatment NSTE-ACS cohort during long-term follow-up.MethodsConsecutive patients (n = 276) with NSTE-ACS undergoing coronary angiography were recruited between September 2012 and May 2015. Six risk scores for all patients were calculated, namely GRACE 2.0, ACEF, SYNTAX, Clinical SYNTAX, SYNTAX II PCI and SYNTAX II CABG. The primary end-point was Major Adverse Cardiovascular Events (MACE) which was a composite of cardiac death, nonfatal myocardial infarction, ischemic stroke or urgent coronary revascularization.ResultsDuring a median follow-up of 33 months, 64 MACE outcomes were recorded (23.2%). There was no difference between risk score categories, except in the highest risk group of ACEF and SYNTAX II PCI scores which exhibited significantly more MACE (51.6%, N = 33 and 45.3%, N = 29, P = 0.024, respectively). In the multivariate Cox regression analysis of individual variables, only age and atrial fibrillation were significant predictors for MACE (HR 1.03, 95% CI 1.00-1.05, P = 0.023 and HR 2.02, 95% CI 1.04-3.89, P = 0.037, respectively). Furthermore, multivariate analysis of the risk scores showed significant prediction of MACE only with ACEF score (HR 2.16, 95% CI 1.36-3.44, P = 0.001). The overall performance of GRACE, SYNTAX, Clinical SYNTAX and SYNTAX II CABG was poor with AUC values of 0.596, 0.507, 0.530 and 0.582, respectively, while ACEF and SYNTAX II PCI showed the best absolute AUC values for MACE (0.630 and 0.626, respectively).ConclusionsACEF risk score showed better discrimination than other risk scores in NSTE-ACS patients undergoing all-treatment strategies over long-term follow-up and it could represent a fast and user-friendly tool to stratify NSTE-ACS patients.
