Antithrombotic Management

Introduction: Guidelines recommend dual-antiplatelet therapy (DAPT) for 12 months in patients with acute coronary syndromes (ACS). Information on patterns and duration of DAPT use after hospital discharge in ACS patients in Asia is sparse. Objective: We describe changes in real-life antithrombotic management patterns (AMPs) up to 2-y post discharge based on data from the EPICOR Asia study (NCT01361386). Methods: This observational study enrolled 12 922 hospital survivors post ACS from 218 hospitals in 8 countries/regions in Asia. Data were collected from symptom onset for the index event (ST-segment elevation myocardial infarction [STEMI] 51.2%, non-STEMI (NSTEMI) 19.9%, or unstable angina [UA] 28.9%), during hospitalization, at discharge and over 2 y follow-up. Results: Overall, 90.6% of patients were on DAPT at hospital discharge which declined to 79.6%, 71.8%, 53.7%, and 45.6% at 6, 12, 18, and 23 months post discharge (Fig). At discharge, most patients (87.6%) received aspirin + clopidogrel, with 79.5%, 71.8%, 53.6%, and 45.4% on this combination at 6, 12, 18, and 23 months. At discharge only 3.0% of patients received aspirin + prasugrel and 1.7% of patients received aspirin + cilostazol. Only 8.3% of patients were on single antiplatelet therapy (SAPT) at discharge with 12.2%, 15.6%, 28.1%, and 30.3% on SAPT at 6, 12, 18, and 23 months post discharge; aspirin being the most commonly used single agent. No notable differences were seen among index event groups. Of the patients on DAPT at discharge, STEMI 93.4%; NSTEMI 90.2%; UA 85.9%, comparable proportions across groups remained on DAPT at 23 months follow up; STEMI 51.0%; NSTEMI 51.9%; UA 47.6%. Conclusions: Most ACS patients remain on DAPT at 12 months and around half remain at 23 months post-discharge. Further study should assess between-country differences, the benefit/risk balance from prolonged DAPT, why DAPT is discontinued before 12 months, and impact on clinical outcomes.

Introduction: Oral surgery (OS) in patients on antecedent dual antiplatelet therapy (DAPT) may be associated with extra bleeding risks. Monitoring platelet activity in such patients may be beneficial for safety when performing OS. Objectives: The aim of this study was to assess whether platelet function during DAPT impacted the risk of bleeding following OS in patients with acute coronary syndromes (ACS). Patients and Methods: Patients who required OS on top of DAPT with aspirin and clopidogrel (n = 55) for invasively treated ACS were included. The control group (n = 33) consisted of patients who underwent OS with no antiplatelet agent. Platelet aggregation before OS was assessed with a Multiplate® analyzer. Bleeding during OS and at days 1, 3, 7 and 10 after surgery was serially evaluated. Results: All 88 patients completed the study. An incomplete response to aspirin or clopidogrel was observed in 43.6% of the patients. In 11% of the cases, an excessive response to clopidogrel was demonstrated. No excessive bleeding upon OS was exhibited in either group during the entire follow-up. Platelet aggregation values and the use of DAPT did not impact the performance of OS. Conclusion: Therapy with clopidogrel and aspirin after ACS does not seem to increase the risk of real-life bleeding following OS, regardless of the platelet activity response to DAPT.

Background: Current clinical guidelines of acute coronary syndromes (ACS) recommend the use of potent antiplatelet therapy, prasugrel or ticagrelor, because both drugs consistently reduce cardiovascular events. Purpose: The aim of this study was to examine temporal changes in the use of optimal antiplatelet therapy in patients with ACS. Methods: A total of 1717 consecutive patients admitted for ACS in 3 tertiary hospitals from February 2014 to December 2015 were enrolled. We divided these 23 months into 4 semesters: period I (0-5 months), period II (6-11 months), period III (12-17 months), and period IV (17-23 months). Demographic, clinical, and treatment data were collected both at admission and at discharge. Results: Treatment with clopidogrel remained constant throughout the periods (52%, 50%, 44%, and 50% for periods I, II, III, and IV, respectively), whereas a progressive increase in ticagrelor treatment was observed (15%, 25%, 26%, and 28%; P = .001). Indeed, new P2Y12 agents showed an increase from 47% at the first semester to 65% in patients with ST-segment elevation myocardial infarction (STEMI), and in patients younger than 75 years from 36% to 53%. However, for patients older than 75 years, diabetic, and patients with end-stage kidney disease, clopidogrel was the second most commonly used antiplatelet agent. Conclusion: In this real-life registry of patients with ACS, we observed there is still a high rate of use of clopidogrel, despite guidelines recommendations, and our analyses also showed a trend toward the use of ticagrelor. Patients who received new antiplatelet agents were patients with STEMI, younger than 75 years, and with less comorbidities. However, the use of ticagrelor and prasugrel remains low, highlighting a therapeutic inertia with considerable gap between evidence-based clinical guidelines and daily clinical practice.

The Impact

The impact of the de-escalation strategy of antiplatelet therapy (APT) on the life expectancy after acute coronary syndromes (ACS) and percutaneous coronary intervention (PCI) requires an assessment in real clinical practice. Into the Russian multicentral observational trial (ORACLE II ClinicalTrials.gov number, NCT04068909), 1803 patients with ACS and PCI indications were enrolled. During 12 months of follow-up, 228 all-cause deaths have occurred. The analysis of death predictors was carried out by the classification tree method. Age, an option of antithrombotic therapy, a history of chronic heart failure, and uric acid level had the greatest prognostic value. The death prediction model’s sensitivity was 82.1% in the training cohort and 79.2% in the test cohort. During the observation period, ticagrelor was replaced with clopidogrel (APT de-escalation) in 357 patients. The groups of patients with different antiplatelet therapy options were adjusted for clinical parameters by the pseudorandomization method. The de-escalation group had the lowerest all-cause death rate. The incidence of bleeding and recurrent nonfatal coronary events in the study groups did not differ significantly. Thus, the APT regimen’s advantage of changing from the maximum in the first weeks after ACS to moderate at follow-up has been confirmed. There is an obvious need to study the possibilities of individualizing antiplatelet therapy in patients after acute coronary syndromes.

The Impact

Background: Dual antiplatelet therapy (DAPT) with aspirin and ticagrelor is recommended for at least 12 months in patients after an acute coronary syndrome (ACS). However, its underuse and premature discontinuation are common in clinical practice. We aimed to investigate the impact of a dedicated follow-up strategy with clinical visits and counselling on adherence levels to ticagrelor in patients after ACS. Methods: PROGRESS (PROmotinG dual antiplatelet therapy adheREnce in the setting of acute coronary Syndromes) is a prospective, randomized trial enrolling 400 ACS patients treated with ticagrelor. Patients were randomized to be followed-up in a dedicated outpatient clinic (In-person follow-up group, [IN-FU], n=200), or with scheduled for phone interviews only (Telephone follow-up group [TEL-FU], n=200), to assess ticagrelor adherence and related complications. DAPT disruption was defined as an interruption of the administration of the drug due to complications or other reasons of non-adherence, and divided according to the duration into short (1-5 days), temporary (6-30 days) and permanent (≥30 days) disruption. The primary endpoint was the rate of DAPT disruption at 1-year follow-up. Results: The rate of ticagrelor disruption at 1 year follow-up was higher in the TEL-FU group than in the IN-FU group (19.6 vs 5.5%; p<0.0001). The IN-FU group reported a significantly lower rate of short (3.0 vs 8.5%; p=0.012) and permanent (2.0 vs 9.6%; p=0.012) disruption than TEL-FU group. The rate of major bleeding did not differ significantly between the 2 groups (p=0.450). Conclusion: The PROGRESS trial showed a net reduction in DAPT disruption in patients followed-up with clinical (in-person) follow-up visits in a dedicated outpatient clinic compared with those scheduled for phone interviews only.
