Treatment Predictors

Oral anticoagulants are essential drugs for the prevention of thromboembolic events in patients with atrial fibrillation (AF). Anticoagulants are, however, commonly withheld in older people due to the risk and fear of hemorrhage. Although the underutilization of anticoagulants in patients with AF has been demonstrated internationally, few studies have been conducted among aged care residents. The aim of this study was to determine the utilization of anticoagulants among people with AF residing in aged care facilities. We performed a non-experimental, retrospective analysis designed to evaluate antithrombotic usage in patients with AF in Australia residing in aged care facilities, using data collected by pharmacists while performing Residential Medication Management Reviews (RMMRs). The utilization of antithrombotic therapy and the appropriateness of therapy were determined based on the CHADS2, CHA2DS2-VASc, and HAS-BLED risk stratification schemes in consideration of documented contraindications to treatment. Predictors of anticoagulant use were determined using multivariate logistic regression. A total of 1952 RMMR patients with AF were identified. Only 35.6% of eligible patients (CHADS2 score ≥2 and no contraindications to anticoagulants) received an anticoagulant. As age increased, the likelihood of receiving an anticoagulant decreased and the likelihood of receiving an antiplatelet or no therapy increased. In patients at high risk of stroke (CHADS score ≥2), utilization of anticoagulants dropped by 19.7% when the HAS-BLED score increased from 2 to 3, suggesting that physicians placed a heavier weighting on bleeding risk rather than stroke risk. Prescribing of anticoagulants was influenced to a greater extent by bleeding risk than it was by the risk of stroke. Further research investigating whether the growing availability of direct oral anticoagulants influences practice in this patient population is needed.

Risk For Bleeding

Introduction: A perceived increased risk of bleeding is one of the most frequent reasons for failure to prescribe anticoagulation for stroke prevention in atrial fibrillation (AF). We previously conducted a randomized controlled trial of alert-based computerized decision support (CDS) to increase prescription of antithrombotic therapy in 458 high-risk hospitalized patients with AF who were not being anticoagulated. Hypothesis: We hypothesized that patients with a perceived high risk for bleeding would have a similar HAS-BLED score and rate of major and clinically-relevant non-major bleeding. Methods: To determine the clinical characteristics and outcomes of these patients determined to be high-risk for bleeding, we analyzed the 248 patients in the alert group. Results: A perceived high risk of bleeding was the most common reason (77%) for omitting antithrombotic therapy. Median HAS-BLED scores were similar in these patients compared with those who were not deemed to have an increased bleeding risk (3 vs. 3, p=0.44). Despite being categorized as too high-risk for bleeding to receive antithrombotic therapy for stroke prevention at the time of the alert, nearly 12% of these patients were ultimately prescribed anticoagulation over the ensuing 90 days. The frequency of major and clinically-relevant non-major bleeding was similar between the two groups. Conclusions: In conclusion, a perceived high risk of bleeding was the most common reason for failure to prescribe antithrombotic therapy after the CDS alert. History of a prior bleeding event or underlying bleeding disorder was not reflected in a higher HAS-BLED score. Implementation of an alert-based CDS with specific attention to assessment of bleeding risk and mitigation warrants further study to encourage adherence to evidence-based clinical practice guideline recommendations for stroke prevention in AF.

The Impact

Abstract Aims Patients with atrial fibrillation undergoing coronary intervention are at higher bleeding risk due to the concomitant need for oral anticoagulation and antiplatelet therapy. The RE-DUAL PCI trial demonstrated better safety with dual antithrombotic therapy (DAT: dabigatran 110 or 150 mg b.i.d., clopidogrel or ticagrelor) compared to triple antithrombotic therapy (TAT: warfarin, clopidogrel or ticagrelor, and aspirin). We explored the impact of baseline bleeding risk based on the PRECISE-DAPT score for decision-making regarding DAT vs. TAT. Methods and results A score ≥25 points qualified high bleeding risk (HBR). Comparisons were made for the primary safety endpoint International Society of Thrombosis and Haemostasis major or clinically relevant non-major bleeding, and the composite efficacy endpoint of death, thrombo-embolic events, or unplanned revascularization, analysed by time-to-event analysis. PRECISE-DAPT was available in 2336/2725 patients, and 37.9% were HBR. Compared to TAT, DAT with dabigatran 110 mg reduced bleeding risk both in non-HBR [hazard ratio (HR) 0.42, 95% confidence interval (CI) 0.31–0.57] and HBR (HR 0.70, 95% CI 0.52–0.94), with a greater magnitude of benefit among non-HBR (Pint = 0.02). Dual antithrombotic therapy with dabigatran 150 mg vs. TAT reduced bleeding in non-HBR (HR 0.60, 95% CI 0.45–0.80), with a trend toward less benefit in HBR patients (HR 0.92, 95% CI 0.63–1.34; Pint = 0.08). The risk of ischaemic events was similar on DAT with dabigatran (both 110 and 150 mg) vs. TAT in non-HBR and HBR patients (Pint = 0.45 and Pint = 0.56, respectively). Conclusions PRECISE-DAPT score appeared useful to identify AF patients undergoing PCI at further increased risk of bleeding complications and may help clinicians identifying the antithrombotic regimen intensity with the best benefit–risk ratio in an individual patient.

Thrombotic Risk

The management of antithrombotic therapy in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) is a challenge cardiologists face daily. The main difficulty is represented by finding the right balance between the prevention of thrombotic risk and the inevitable increase in bleeding. Most guidelines recommend the use of both oral anticoagulants and dual antiplatelet therapy in combination (triple therapy) in patients with FA undergoing PCI, suggesting however immediate use of dual antithrombotic therapy in patients with prevalent bleeding risk. Many studies show that triple therapy is associated with high frequency of major bleeding, thus stimulating the research for new therapeutic strategies. We report the case of a patient suffering from hypertension, dyslipidemia and epistaxis, hospitalized for the onset of angina associated with moderate efforts. Despite scientific evidence to support the use of dual therapy with dabigatran, the patient's detailed clinical history shows that this type of approach has not yet entered into current clinical practice, although the final therapeutic choice is in line with the results of the RE-DUAL PC study (Cardiology).
