We report two cases of immune thrombocytopenic purpura (ITP) associated with acute coronary artery syndrome highlighting the interventions done in every case along with the medications used during intervention and as outpatient. The first case is that of a woman with ITP exacerbation while on dual antiplatelet therapy and the second case is that of a male presenting with non-ST elevation myocardial infarction (NSTEMI) while in a thrombocytopenic crisis. In both cases antiplatelet therapy was held and thrombopoietic therapy was initiated before resuming full anticoagulation and coronary intervention. Given the paucity of data on ITP and antiplatelets treatment in the setting of acute coronary syndrome, no strict recommendations can be proposed, but antiplatelets appear to be safe acutely and in the long term in this category of patients as long as few measures are undertaken to minimize the risks of bleeding and thrombosis.

Bleeding represents the most important complication of antithrombotic treatment, including anticoagulant and antiplatelet therapies. A number of scores were proposed to evaluate the risk of bleeding both for anticoagulant and antiplatelet treatment. In the last decade, 5 bleeding risk scores were published for use in atrial fibrillation patients, and 3 scores for patients receiving anticoagulants for venous thromboembolism therapy or prophylaxis. In addition, 3 scores were recently developed to assess inhospital or short-term bleeding risk in patients receiving antiplatelet therapy after Acute Coronary Syndrome (ACS) and Percutaneous Coronary Intervention (PCI). Furthermore, 3 additional scores have focused on long-term bleeding in outpatients receiving dual antiplatelet therapy after PCI. The aim of this review is to consider the evidence on bleeding scores.

Background: Long term outcomes of culprit multi-vessel and left main patients who presented with Non-ST Elevation Acute Coronary Syndrome (NSTE-ACS) and underwent either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) are not well defined. Randomized trials comparing the two modalities constituted mainly of patients with stable coronary artery disease (SCAD). We performed a meta-analysis of studies that compared the long term outcomes of CABG vs. PCI in NSTE-ACS. Methods: Medline, EmCare, CINAHL, Cochrane databases were queried for relevant articles. Studies that included patients with SCAD and ST-elevation myocardial infarction were excluded. Our primary outcome was major adverse cardiac events (MACE) at 3-5 years, defined as a composite of all-cause mortality, stroke, re-infarction and repeat revascularization. The secondary outcome was re-infarction at 3 to 5 years. We used the Paule-Mandel method with Hartung-Knapp-Sidik-Jonkman adjustment to estimate risk ratio (RR) with 95% confidence interval (CI). Heterogeneity was assessed using Higgin’s I 2 statistics. All statistical analysis was carried out using R version 3.6.2 Results: Four observational studies met our inclusion criteria with a total number of 6695 patients. At 3 to 5 years, the PCI group was associated with a higher risk of MACE as compared to CABG, (RR): 1.52, 95% CI: 1.28 to 1.81, I 2 =0% (PANEL A). The PCI group also had a higher risk of re-infarctions during the period of follow up, RR: 1.88, 95% CI 1.49 to 2.38, I 2 =0% (PANEL B). Conclusion: In this meta-analysis, CABG was associated with a lower risk of MACE and re-infarctions as compared to PCI during 3 to 5 years follow up period.

Objectives: To evaluate the safety of dual antiplatelet therapy in patients in whom long-term anticoagulation (AC) with warfarin is recommended. Background: It is well established that antiplatelet therapy with aspirin ad thienopiridines is required following percutaneous coronary intervention (PCI) with stent implantation. Some patients have also indication for long-term AC. The optimal antithrombotic strategy following PCI in such patients is unclear. Methods: All consecutive patients who underwent PCI with stent implantation discharged on triple therapy (defined as the combination of aspirin and thienopyridines and AC with warfarin) were analyzed. Results One-hundred and twenty-seven patients with 224 lesions: 86.6% males, mean age 69.9±8.8 years were included in the study. Drug-eluting stents (DES) were positioned in 71 (55.9%) and bare metal stent (BMS) in 53 (41.7%) patients. Atrial fibrillation (AF) was the main indication (59.1%) for AC treatment, followed by prosthetic valves (12.4%) and mural left ventricular (LV) thrombus (9.1%). Average risk of thromboembolic events in the subgroup with AF was 1.79 ± 1.23 according to CHADS2 score. The mean triple therapy duration was 5.6±4.6 and clinical follow-up 21.0±19.8 months. During the triple therapy period, 6 patients (4.7%) developed major bleeding complications; 67% of which occurred within the first month. No significant differences between DES and BMS were observed in the incidence of major (respectively 5.6% vs. 3.8%, p=1.0) and minor bleeding (respectively 1.4% vs. 3.8%, p=0.57) and mortality (respectively 5.6% vs. 1.9%, p=0.39). Four patients died in DES group: 3 of major bleeding complications and one of ischemic stroke. The only death in the BMS group was due to subarachnoid hemorrhage. A significant difference was observed in favor of DES in target vessel revascularization (14.1% vs. 28.3%, p=0.041). Conclusions: While on triple therapy, major bleeding complications occurred in 4.7% of patients, half of them were lethal and most (67%) occurred within the first month.

Background Long‐term use of antiplatelet agents after acute coronary syndrome in diabetic patients is not well known. Here, we describe antiplatelet use and outcomes in such patients enrolled in the EPICOR Asia (Long‐Term Follow‐up of Antithrombotic Management Patterns in Acute Coronary Syndrome Patients in Asia) registry. Methods and Results EPICOR Asia is a prospective, observational study of 12 922 patients with acute coronary syndrome surviving to discharge, from 8 countries/regions in Asia. The present analysis included 3162 patients with diabetes mellitus (DM) and 9602 patients without DM. The impact of DM on use of antiplatelet agents and events (composite of death, myocardial infarction, and stroke, with or without any revascularization; individual components, and bleeding) was evaluated. Significant baseline differences were seen between patients with DM and patients without DM for age, sex, body mass index, cardiovascular history, angiographic findings, and use of percutaneous coronary intervention. At discharge, ≈90% of patients in each group received dual antiplatelet therapy. At 2‐year follow‐up, more patients with DM tended to still receive dual antiplatelet therapy (60% versus 56%). DM was associated with increased risk from ischemic but not major bleeding events. Independent predictors of the composite end point of death, myocardial infarction, and stroke in patients with DM were age ≥65 years and use of diuretics at discharge. Conclusions Antiplatelet agent use is broadly comparable in patients with DM and patients without DM, although patients with DM are more likely to be on dual antiplatelet therapy at 2 years. Patients with DM are at increased risk of ischemic events, suggesting an unmet need for improved antithrombotic treatment.

Objective. We aim to evaluate the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with high-risk coronary anatomy (HRCA). Background. Coronary disease severity is important for therapeutic decision-making and prognostication among patients presenting with NSTE-ACS. However, long-term outcome in patients undergoing percutaneous coronary intervention (PCI) with HRCA is still unknown. Method. NSTE-ACS patients undergoing PCI in Fuwai Hospital in 2013 were prospectively enrolled and subsequently divided into HRCA and low-risk coronary anatomy (LRCA) groups according to whether angiography complies with the HRCA definition. HRCA was defined as left main disease >50%, proximal LAD lesion >70%, or 2- to 3- vessel disease involving the LAD. Prognosis impact on 2-year and 5-year major adverse cardiovascular and cerebrovascular events (MACCE) is analyzed. Results. Out of 4,984 enrolled patients with NSTE-ACS, 3,752 patients belonged to the HRCA group, while 1,232 patients belonged to the LRCA group. Compared with the LRCA group, patients in the HRCA group had worse baseline characteristics including higher age, more comorbidities, and worse angiographic findings. Patients in the HRCA group had higher incidence of unplanned revascularization (2 years: 9.7% vs. 5.1%, p<0.001; 5 years: 15.4% vs. 10.3%, p<0.001), 2-year MACCE (13.1% vs. 8.8%, p<0.001), and 5-year death/MI/revascularization/stroke (23.0% vs. 18.4%, p=0.001). Kaplan–Meier survival analysis showed similar results. After adjusting for confounding factors, HRCA is independently associated with higher risk of revascularization (2 years: HR = 1.636, 95% CI: 1.225–2.186; 5 years: HR = 1.460, 95% CI: 1.186–1.798), 2-year MACCE (HR = 1.275, 95% CI = 1.019–1.596) and 5-year death/MI/revascularization/stroke (HR = 1.183, 95% CI: 1.010–1.385). Conclusion. In our large cohort of Chinese patients, HRCA is an independent risk factor for long-term unplanned revascularization and MACCE.

Antiplatelet therapy is the cornerstone in the modern therapy of patients with acute coronary syndromes (ACS), because of the unique role of platelets in coronary thrombosis. Clopidogrel in combination with aspirin is the current “gold standard” for reducing cardiovascular events in such patients, providing a synergistic platelet inhibition through different platelet activation pathways. Clopidogrel is a thienopyridine which inhibits ADP-induced platelet aggregation, with no direct effects on the metabolism of arachidonic acid. Due to a better safety profile with a similar antiplatelet effectiveness, it is preferred to ticlopidine. In patients with ACS without ST segment elevation (NSTEMI), clopidogrel plus aspirin is able to reduce the relative risk of adverse cardiovascular events by 20%, compared with aspirin alone. Clopidogrel plays a key role also in patients undergoing coronary stenting, in order to prevent stent thrombosis. Pretreatment and long-term treatment with clopidogrel reduces by about one-third the risk of cardiovascular death or myocardial infarction in NSTEMI ACS patients undergoing percutaneous coronary angioplasty (PCI). However, a long-term dual antiplatelet therapy is associated with a higher rate of bleeding events. Clinical practice guidelines currently recommend long-term dual antiplatelet therapy with aspirin and clopidogrel in patients with ACS and a pre-treatment with clopidogrel in every patient scheduled for PCI. The concept of clopidogrel resistance and the need for a pretreatment in patients undergoing coronary stent implantation led to the concept that an improved antiplatelet regimen with novel drugs is desirable.
