Coronary Syndrome

Inhibition of platelet function by means of dual antiplatelet therapy (DAPT) is the cornerstone of treatment of acute coronary syndrome (ACS). While preventing ischemic recurrences, inhibition of platelet function is clearly associated with an increased bleeding risk, a feared complication that may lead to significant morbidity and mortality. Since bleeding risk management is intrinsically associated with therapeutic adjustments undertaken during the whole clinical history of patients with acute coronary syndrome, single decisions taken from the very first day to years of follow-up might be decisive. This review aims at providing a clinically oriented, patient-tailored approach in reducing the risk and manage bleeding complications in ACS patients treated with DAPT. The steps in clinical decision making from the day of ACS to follow-up are analyzed. New treatment strategies to enhance the safety of DAPT are also described.

Abstract Introduction Very few patients with history of cancer are included in clinical trials. With this study from real-life patients, we try to analyze the ischemic and bleeding risk of patients with history of cancer who were treated with dual antiplatelet therapy (DAPT) after an acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods The data analyzed in this study were obtained from the fusion of 3 clinical registries of ACS patients: BleeMACS (2004–2013), CardioCHUVI/ARRITXACA (2010–2016) and RENAMI (2013–2016). All 3 registries include consecutive patients discharged after an ACS with DAPT and undergoing PCI. The merged data set contain 26,076 patients. A propensity-matched analysis was performed to match the baseline characteristics of patients with and without previous history of recent cancer. The impact of prior cancer in the ischemic and bleeding risk was assessed by a competitive risk analysis, using a Fine and Gray regression model, with death being the competitive event. For ischemic risk we have considered a new acute myocardial infarction (AMI), whereas for bleeding risk we have considered major bleeding (MB) defined as bleeding requiring hospital admission. All events occurred with DAPT, as follow-up time was censored by DAPT suspension/withdrawal. Results From the 26,076 ACS patients, 1,661 have prior history of cancer (6.4%). Patients with cancer were older, and with more cardiovascular risk factors. DAPT with prasugrel/ticagrelor was less frequently prescribed in patients with cancer in comparison with the rest of the population (14.5% vs 22.4%, p<0.001). During a mean follow-up of 12.2±4.8 months, 964 patients died (3.7%), and 640 AMI (2.5%) and 685 MB (2.6%) were reported. The unadjusted cumulative incidences of AMI and MB were higher in patients with prior cancer (5.1 and 5.2 per 100 patients/year, respectively) than in those with prior cancer (2.4 and 2.6 per 100 patients/year, respectively). After propensity-score matching, we obtained two matched groups of 1,656 patients. Patients with prior cancer showed a significant higher risk of AMI (sHR 1.44, 95% CI 1.01–2.04, p=0.044), but not higher risk of MB (sHR 1.21, 95% CI 0.88–1.68, p=0.248), in comparison with those without prior cancer. Conclusions In ACS patients discharged with DAPT after PCI, prior history of cancer is an independent factor of higher ischemic risk – in terms of AMI, but it is not an independent predictor of increased hemorrhagic risk.

St Segment

The American Heart Association/American College of Cardiology in 2014 published a focused update of the 2007 and 2012 guidelines for non–ST-segment elevation acute coronary syndrome (NSTE-ACS). The management of ST-segment elevation myocardial infarction (STEMI) is described in a separate guideline published in 2013. The focused updates to the guidelines contain updated recommendations for dual antiplatelet therapy, including use of the P2Y12 inhibitor ticagrelor, which was recently approved by the Food and Drug Administration. Nurses caring for patients with acute coronary syndrome must have a good understanding of the current treatment guidelines for such patients, to help ensure delivery of evidence-based care. This review article uses a case study–based approach to describe how the new guidelines affect clinical decision making when choosing appropriate antiplatelet therapy for patients with NSTE-ACS or STEMI, depending on the patient’s clinical history and presenting characteristics.

Background: Being overweight increases the risk of cardiovascular diseases and mortality. However, among high-body-weight patients with established acute coronary syndrome (ACS) this evidence is not clear. In this scenario, a low body weight (LBW) has been proposed to confer higher prognostic risk and higher bleeding risk with new P2Y12 inhibitors. Aims: We aimed to examine differences in mortality, catheterizations/revascularizations, antiplatelet therapy and ischemic/bleeding adverse events between ACS patients with LBW. Methods: This is a multicenter registry involving 1576 consecutive ACS patients (ST-elevation myocardial infarction (STEMI), non-STEMI, or unstable angina) from three tertiary institutions. Patients were divided into two groups: LBW (weight < 60 kg, n = 176) and non-LBW (weight ⩾ 60 kg, n = 1400). During 12 months follow-up, we recorded management (catheterizations/revascularizations), antiplatelet therapy, major adverse cardiovascular events (MACEs), bleeding events (BARC classification), and mortality. Results: Catheterizations (86.4% vs. 93.4%; p = 0.001) and revascularizations (64.8% vs. 76.1%; p = 0.001) were significantly lower in the LBW group. At discharge, prescription of new P2Y12 inhibitors was also lower in LBW patients (24.4% vs. 37.8%; p = 0.001). After 12-month follow-up, the incidence of MACE (HR 1.61 (95% CI 1.03–2.50]; p = 0.038) and mortality (HR 2.18 (95% CI 1.33–3.58); p = 0.002) was higher in LBW patients compared with non-LBW. In contrast, there were no significant differences for bleeding events. Conclusions: LBW in ACS patients was associated with higher incidence of MACE and mortality. In this group of patients less catheterizations and coronary revascularizations were performed. Despite there being no differences in bleeding rates, new P2Y12 inhibitors were less prescribed in LBW patients.

Antithrombotic Management

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.

Abstract Introduction Peripheral artery disease (PAD) is associated with heightened ischemic and bleeding risk in patients with acute coronary syndrome (ACS). With this study from real-life patients, we try to analyze the balance between ischemic and bleeding risk during treatment with dual antiplatelet therapy (DAPT) after an ACS according to the presence or not of PAD. Methods The data analyzed in this study were obtained from the fusion of 3 clinical registries of ACS patients: BleeMACS (2004–2013), CardioCHUVI/ARRITXACA (2010–2016) and RENAMI (2013–2016). All 3 registries include consecutive patients discharged after an ACS with DAPT and undergoing PCI. The merged data set contain 26,076 patients. A propensity-matched analysis was performed to match the baseline characteristics of patients with and without PAD. The impact of prior PAD in the ischemic and bleeding risk was assessed by a competitive risk analysis, using a Fine and Gray regression model, with death being the competitive event. For ischemic risk we have considered a new acute myocardial infarction (AMI), whereas for bleeding risk we have considered major bleeding (MB) defined as bleeding requiring hospital admission. Follow-up time was censored by DAPT suspension/withdrawal. Results From the 26,076 ACS patients, 1,600 have PAD (6.1%). Patients with PAD were older, and with more cardiovascular risk factors. DAPT with prasugrel/ticagrelor was less frequently prescribed in patients with PAD in comparison with the rest of the population (8.2% vs 22.8%, p<0.001). During a mean follow-up of 12.2±4.8 months, 964 patients died (3.7%), and 640 AMI (2.5%) and 685 MB (2.6%) were reported. After propensity-score matching, we obtained two matched groups of 1,591 patients. Patients with PAD showed a significant higher risk of both AMI (sHR 2.17, 95% CI 1.51–3.10, p<0.001) and MB (sHR 1.51, 95% CI 1.07–2.12, p=0.018), in comparison with those without PAD. The cumulative incidence of AMI was 63.9 and 29.8 per 1,000 patients/year in patients with and without PAD, respectively. The cumulative incidence of MB was 55.9 and 37.6 per 1,000 patients/year in patients with and without PAD, respectively. The rate difference per 1,000 patient-years for AMI between patients with and without PAD was +34.1 (95% CI 30.1–38.1), and for MB +18.3 (16.1–20.4). The net balance between ischemic and bleeding events comparing patients with and without PAD was positive (+15.8 per 1,000 patients/year, 95% CI 9.7–22.0). Conclusions PAD was associated with higher ischemic and bleeding risk after hospital discharge for ACS treated with DAPT. However, the balance between ischemic and bleeding risk was positive for patients with PAD in comparison with patients without PAD. As summary, ACS patients with PAD had an ischemic risk greater than the bleeding risk.

Conflicting results have been reported so far in pooled analyses and studies evaluating the optimum duration of dual antiplatelet therapy (DAPT) in acute coronary syndrome (ACS) patients. However, randomized clinical trials dedicated to this specific setting of higher thrombotic risk patients have only recently been completed, pointing at the noninferiority of a shorter strategy as compared to the traditional 12-month DAPT, furthermore allowing to reduce the risk of major bleeding complications. Therefore, a reconsideration of current clinical practice and guidelines should be certainly be advocated in light of the most recent updates, especially among ACS patients treated with percutaneous coronary intervention (PCI) and modern drug-eluting stents (DES). Our aim was to provide a comprehensive review of the available evidence on the optimal DAPT duration in ACS patients.
