- The role of platelet function testing in acute coronary syndrome patients undergoing percutaneous coronary intervention remains controversial despite the fact that high platelet reactivity is an independent predictor of stent thrombosis and emerging evidence suggests also a link between low platelet reactivity and bleeding. In this expert opinion paper, the Study Group on Biomarkers in Cardiology of the Acute Cardiovascular Care Association and the Working Group on Thrombosis of the European Society of Cardiology aim to provide an overview of current evidence in this area and recommendations for practicing clinicians.

- Background Among patients with STEMI in the ATLANTIC study, pre-hospital administration of ticagrelor improved post-PCI ST-segment resolution and 30-day stent thrombosis. We investigated whether this clinical benefit with pre-hospital ticagrelor differs by ischemic duration. Methods In a post hoc analysis we compared absence of ST-segment resolution post-PCI and stent thrombosis at 30 days between randomized treatment groups (pre-versus in-hospital ticagrelor) stratified by symptom onset to first medical contact (FMC) duration [amp;lt;= 1 hour (n = 773), amp;gt;1 to amp;lt;= 3 hours (n = 772), and amp;gt;3 hours (n = 311)], examining the interaction between randomized treatment strategy and duration of symptom onset to FMC for each outcome. Results Patients presenting later after symptom onset were older, more likely to be female, and have higher baseline risk. Patients with symptom onset to FMC amp;gt;3 hours had the greatest improvement in post-PCI ST-segment elevation resolution with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 2.9% vs. amp;gt;1 to amp;lt;= 3 hours, 3.6% vs. amp;gt;3 hours, 12.2%; adjusted p for interaction = 0.13), while patients with shorter duration of ischemia had greater improvement in stent thrombosis at 30 days with pre-versus in-hospital ticagrelor (absolute risk difference: amp;lt;= 1 hour, 1.3% vs. amp;gt;1 hour to amp;lt;= 3hours, 0.7% vs. amp;gt;3 hours, 0.4%; adjusted p for interaction = 0.55). Symptom onset to active ticagrelor administration was independently associated with stent thrombosis at 30 days (adjusted OR 1.89 per 100 minute delay, 95% CI 1.20-2.97, P amp;lt; .01), but not post-PCI ST-segment resolution (P = .41). Conclusions The effect of pre-hospital ticagrelor to reduce stent thrombosis was most evident when given early within 3 hours after symptom onset, with delay in ticagrelor administration after symptom onset associated with higher rate of stent thrombosis. These findings re-emphasize the need for early ticagrelor administration in primary PCI treated STEMI patients.

- BACKGROUND AND AIMS: Patients with long atrial high-rate episodes (AHRE) ≥ 24 hours and stroke risk factors are often treated with anticoagulation for stroke prevention. Anticoagulation has never been compared to no anticoagulation in these patients.METHODS: This secondary prespecified analysis of NOAH-AFNET 6 examined interactions between AHRE duration at baseline and anticoagulation with edoxaban compared to placebo in patients with AHRE and stroke risk factors. The primary efficacy outcome was a composite of stroke, systemic embolism, or cardiovascular death. The safety outcome was a composite of major bleeding and death. Key secondary outcomes were components of these outcomes and ECG-diagnosed atrial fibrillation.RESULTS: AHRE ≥24 hours were present at baseline in 259/2389 patients enrolled in NOAH-AFNET 6 (11%, 78 ± 7 years old, 28% women, CHA2DS2-VASc score 4). Clinical characteristics were not different from patients with shorter AHRE. During a median follow-up of 1.8 years, the primary outcome occurred in 9/132 patients with AHRE ≥24 hours (4.3%/patient-year, 2 strokes) treated with anticoagulation and in 14/127 patients treated with placebo (6.9%/patient-year, 2 strokes). AHRE duration did not interact with the efficacy (p-interaction = 0.65) or safety (p-interaction = 0.98) of anticoagulation. Analyses including AHRE as a continuous parameter confirmed this. Patients with AHRE ≥24 hours developed more ECG-diagnosed atrial fibrillation (17.0%/patient-year) than patients with shorter AHRE (8.2%/patient-year; p < 0.001).CONCLUSIONS: This hypothesis-generating analysis does not find an interaction between AHRE duration and anticoagulation therapy in patients with device-detected AHRE and stroke risk factors. Further research is needed to identify patients with long AHRE at high stroke risk.

- Self-terminating atrial arrhythmias are commonly detected on continuous rhythm monitoring, e.g. by pacemakers or defibrillators. It is unclear whether the presence of these arrhythmias has therapeutic consequences. We sought to summarize evidence on the prevalence of atrial high-rate episodes (AHREs) and their impact on risk of stroke. We performed a comprehensive, tabulated review of published literature on the prevalence of AHRE. In patients with AHRE, but without atrial fibrillation (AF), we reviewed the stroke risk and the potential risk/benefit of oral anticoagulation. Atrial high-rate episodes are found in 10-30% of AF-free patients. Presence of AHRE slightly increases stroke risk (0.8% to 1%/year) compared with patients without AHRE. Atrial high-rate episode of longer duration (e.g. those >24 h) could be associated with a higher stroke risk. Oral anticoagulation has the potential to reduce stroke risk in patients with AHRE but is associated with a rate of major bleeding of 2%/year. Oral anticoagulation is not effective in patients with heart failure or survivors of a stroke without AF. It remains unclear whether anticoagulation is effective and safe in patients with AHRE. Atrial high-rate episodes are common and confer a slight increase in stroke risk. There is true equipoise on the best way to reduce stroke risk in patients with AHRE. Two ongoing trials (NOAH-AFNET 6 and ARTESiA) will provide much-needed information on the effectiveness and safety of oral anticoagulation using non-vitamin K antagonist oral anticoagulants in patients with AHRE.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Frailty may modify the risk-benefit profile of certain treatments, and frail patients may have reduced tolerance to treatments. OBJECTIVE: To investigate the efficacy of dapagliflozin according to frailty status, using the Rockwood cumulative deficit approach, in DAPA- HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure). DESIGN: Post hoc analysis of a phase 3 randomized clinical trial. (ClinicalTrials.gov: NCT03036124). SETTING: 410 sites in 20 countries. PATIENTS: Patients with symptomatic heart failure (HF) with a left ventricular ejection fraction of 40% or less and elevated natriuretic peptide. INTERVENTION: Addition of once-daily 10 mg of dapagliflozin or placebo to guideline-recommended therapy. MEASUREMENTS: The primary outcome was worsening HF or cardiovascular death. RESULTS: Of the 4744 patients randomly assigned in DAPA-HF, a frailty index (FI) was calculable in 4742. In total, 2392 patients (50.4%) were in FI class 1 (FI $<$/=0.210; not frail), 1606 (33.9%) in FI class 2 (FI 0.211 to 0.310; more frail), and 744 (15.7%) in FI class 3 (FI $>$/=0.311; most frail). The median follow-up time was 18.2 months. Dapagliflozin reduced the risk for worsening HF or cardiovascular death, regardless of FI class. The differences in event rate per 100 person-years for dapagliflozin versus placebo from lowest to highest FI class were -3.5 (95% CI, -5.7 to -1.2), -3.6 (CI, -6.6 to -0.5), and -7.9 (CI, -13.9 to -1.9). Consistent benefits were observed for other clinical events and health status, but the absolute reductions were generally larger in the most frail patients. Study drug discontinuation and serious adverse events were not more frequent with dapagliflozin than placebo, regardless of FI class. LIMITATION: Enrollment criteria precluded the inclusion of very high-risk patients. CONCLUSION: Dapagliflozin improved all outcomes examined, regardless of frailty status. However, the absolute reductions were larger in more frail patients. PRIMARY FUNDING SOURCE: AstraZeneca.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Frailty is increasing in prevalence. Because patients with frailty are often perceived to have a less favorable risk/benefit profile, they may be less likely to receive new pharmacologic treatments. We investigated the efficacy and tolerability of dapagliflozin according to frailty status in patients with heart failure with mildly reduced or preserved ejection fraction randomized in DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure). METHODS: Frailty was measured using the Rockwood cumulative deficit approach. The primary end point was time to a first worsening heart failure event or cardiovascular death. RESULTS: Of the 6263 patients randomized, a frailty index (FI) was calculable in 6258. In total, 2354 (37.6%) patients had class 1 frailty (FI $<$/=0.210; ie, not frail), 2413 (38.6%) had class 2 frailty (FI 0.211-0.310; ie, more frail), and 1491 (23.8%) had class 3 frailty (FI $>$/=0.311; ie, most frail). Greater frailty was associated with a higher rate of the primary end point (per 100 person-years): FI class 1, 6.3 (95% CI 5.7-7.1); class 2, 8.3 (7.5-9.1); and class 3, 13.4 (12.1-14.7; P$<$0.001). The effect of dapagliflozin (as a hazard ratio) on the primary end point from FI class 1 to 3 was 0.85 (95% CI, 0.68-1.06), 0.89 (0.74-1.08), and 0.74 (0.61-0.91), respectively (Pinteraction=0.40). Although patients with a greater degree of frailty had worse Kansas City Cardiomyopathy Questionnaire scores at baseline, their improvement with dapagliflozin was greater than it was in patients with less frailty: placebo-corrected improvement in Kansas City Cardiomyopathy Questionnaire Overall Summary Score at 4 months in FI class 1 was 0.3 (95% CI, -0.9 to 1.4); in class 2, 1.5 (0.3-2.7); and in class 3, 3.4 (1.7-5.1; Pinteraction=0.021). Adverse reactions and treatment discontinuation, although more frequent in patients with a greater degree of frailty, were not more common with dapagliflozin than with placebo irrespective of frailty class. CONCLUSIONS: In DELIVER, frailty was common and associated with worse outcomes. The benefit of dapagliflozin was consistent across the range of frailty studied. The improvement in health-related quality of life with dapagliflozin occurred early and was greater in patients with a higher level of frailty. REGISTRATION: URL: https://www.

- BACKGROUND: Triple antithrombotic therapy with warfarin plus two antiplatelet agents is the standard of care after percutaneous coronary intervention (PCI) for patients with atrial fibrillation, but this therapy is associated with a high risk of bleeding.METHODS: inhibitor (clopidogrel or ticagrelor) and no aspirin (110-mg and 150-mg dual-therapy groups). Outside the United States, elderly patients (≥80 years of age; ≥70 years of age in Japan) were randomly assigned to the 110-mg dual-therapy group or the triple-therapy group. The primary end point was a major or clinically relevant nonmajor bleeding event during follow-up (mean follow-up, 14 months). The trial also tested for the noninferiority of dual therapy with dabigatran (both doses combined) to triple therapy with warfarin with respect to the incidence of a composite efficacy end point of thromboembolic events (myocardial infarction, stroke, or systemic embolism), death, or unplanned revascularization.RESULTS: The incidence of the primary end point was 15.4% in the 110-mg dual-therapy group as compared with 26.9% in the triple-therapy group (hazard ratio, 0.52; 95% confidence interval [CI], 0.42 to 0.63; P<0.001 for noninferiority; P<0.001 for superiority) and 20.2% in the 150-mg dual-therapy group as compared with 25.7% in the corresponding triple-therapy group, which did not include elderly patients outside the United States (hazard ratio, 0.72; 95% CI, 0.58 to 0.88; P<0.001 for noninferiority). The incidence of the composite efficacy end point was 13.7% in the two dual-therapy groups combined as compared with 13.4% in the triple-therapy group (hazard ratio, 1.04; 95% CI, 0.84 to 1.29; P=0.005 for noninferiority). The rate of serious adverse events did not differ significantly among the groups.CONCLUSIONS: inhibitor, and aspirin. Dual therapy was noninferior to triple therapy with respect to the risk of thromboembolic events. (Funded by Boehringer Ingelheim; RE-DUAL PCI ClinicalTrials.gov number, NCT02164864)

- AimsThe European Society of Cardiology Heart Failure Long-Term Registry (ESC-HF-LT-R) was set up with the aim of describing the clinical epidemiology and the 1-year outcomes of patients with heart failure (HF) with the added intention of comparing differences between participating countries. Methods and resultsThe ESC-HF-LT-R is a prospective, observational registry contributed to by 211 cardiology centres in 21 European and/or Mediterranean countries, all being member countries of the ESC. Between May 2011 and April 2013 it collected data on 12440 patients, 40.5% of them hospitalized with acute HF (AHF) and 59.5% outpatients with chronic HF (CHF). The all-cause 1-year mortality rate was 23.6% for AHF and 6.4% for CHF. The combined endpoint of mortality or HF hospitalization within 1year had a rate of 36% for AHF and 14.5% for CHF. All-cause mortality rates in the different regions ranged from 21.6% to 36.5% in patients with AHF, and from 6.9% to 15.6% in those with CHF. These differences in mortality between regions are thought reflect differences in the characteristics and/or management of these patients. ConclusionThe ESC-HF-LT-R shows that 1-year all-cause mortality of patients with AHF is still high while the mortality of CHF is lower. This registry provides the opportunity to evaluate the management and outcomes of patients with HF and identify areas for improvement.
