- BACKGROUND: In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. METHODS: Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. RESULTS: Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher in the PCI-treated group ($4,602 vs $3,807; P = .047), as well as the cost of drugs ($1,309 vs $1,202; P = .001), whereas the cost of hospitalization was lower ($7,344 vs $9,278; P = .025). The cost of investigations, outpatient care, and loss of production did not differ significantly between the 2 treatment arms. Total cost and quality-adjusted survival were $25,315 and 0.759 vs $27,819 and 0.728 (both not significant) for the primary PCI and thrombolysis groups, respectively. Based on the 1-year follow-up, bootstrap analysis revealed that in 80%, 88%, and 89% of the replications, the cost per health outcome gained for PCI will be <$0, $50,000, and $100,000 respectively. CONCLUSION: In a 1-year perspective, there was a tendency toward lower costs and better health outcome after primary PCI, resulting in costs for PCI in comparison to thrombolysis that will be below the conventional threshold for cost-effectiveness in 88% of bootstrap replications.

- 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: Abciximab is established as adjunct to primary percutaneous coronary intervention (PCI). Based on some smaller studies, ST-segment elevation myocardial infarction (STEMI) networks in various European countries have adopted the start of abciximab before transfer to the catheterization laboratory (cathlab) hospital as part of their routine treatment options. Although a recently published study did not reveal improved clinical outcome when starting abciximab before the cathlab, a potential benefit from such early administration, in particular in the setting of transfer networks, remains unclear and has been the subject of debate. Methods: Data of consecutive patients with STEMI transferred for primary PCI in hospital/ambulance-feeded STEMI networks treated between November 2005 and January 2007 at 15 PCI centers from 7 European countries were collected in the web-based EUROTRANSFER Registry. Results: Data from a total of 1,650 patients were collected. Abciximab was administered to 1086 patients (66%), of whom 727 received early abciximab (EA group: abciximab started before admission to cathlab, at least 30 minutes before balloon). Another 359 patients received late abciximab (LA group: periprocedural administration of abciximab in the cathlab). Preprocedural TIMI 3 flow was observed in 17.7% of patients with EA and in 8.9% in the LA group (P < .0001). Thirty-day mortality was 3.9% in the EA group versus 7.5% with LA (OR 0.49, 95% CI 0.29-0.85, P = .011), and composite 30-day outcome including death, repeated myocardial infarction, and urgent revascularization was present in 5.5% and 10.3%, respectively (OR 0.5 1, 95% CI 0.32-0.81, P = .004). These differences remain statistically significant in favor of early abciximab after accounting and adjustment for differences between the groups by means of a multivariate regression model and propensity score. Conclusions: Patients in STEMI networks transferred for primary PCI who have received abciximab before transfer rather than in the cathlab had more patent arteries before PCI and showed lower rates for death and the composite clinical outcome at 30-day follow-up.

- BackgroundTreatment strategies, either invasive or noninvasive, for patients with unstable coronary artery disease still vary. There are no published studies comparing the strategies for health-related quality of life.MethodsA total of 2457 patients with unstable coronary artery disease were randomized. We prospectively recorded the patients' health-related quality of life using 2 questionnaires, the generic Medical Outcomes Study Short Form 36 (SF-36) and the disease-specific Angina Pectoris Quality of Life Questionnaire (APQLQ), at randomization and after 3, 6, and 12 months of follow-up.ResultsThere was a high response rate (92%) at randomization, with 2251 respondents. The invasively treated group showed a significantly better quality of life in all 8 scales and both component scores at the 3- and 6-month follow-up (P <.01) than the noninvasively treated group. These differences remained at the 12-month follow-up, with significance in 7 of the scales and in the physical component score. The disease-specific quality of life results were similar until the 6-month follow-up. At randomization, the unstable population showed a remarkably lower quality of life in all 8 scales and the component scores compared with an age- and sex-matched normative population.ConclusionsPatients receiving early invasive intervention after an unstable episode had substantial improvement in health-related quality of life until the 1-year follow-up, compared with patients receiving noninvasive treatment. Health-related quality of life in an unstable coronary artery disease population is remarkably lower than in a matched normative population.

- Background Atrial fibrillation (AF) is associated with substantial morbidity, in particular stroke. Despite good evidence for the reduction of stroke risk with anticoagulant therapy, there remains a significant undertreatment. The main aim of the current study is to investigate whethera clinical decision support tool for stroke prevention (CDS) integrated in the electronic health record can improve adherence to guidelines for stroke prevention in patients with AF. Methods We will conduct a cluster randomized trial where 43 primary care clinics in the county of Ostergotland, Sweden (population 444,347), will be randomized to be part of the CDS intervention or serve as controls. The CDS will alert responsible physicians of patients with AF and increased risk for thromboembolism according to the CHA(2)DS(2)VASc (Congestive heart failure, Hypertension, Age 74 years, Diabetes mellitus, previous Stroke/TIA/thromboembolism, Vascular disease, Age 65-74 years, Sex category (i.e. female sex)) algorithm without anticoagulant therapy. The primary end point will be adherence to guidelines after 1 year. Conclusion The present study will investigate whether a clinical decision support system integrated in an electronic health record can increase adherence to guidelines regarding anticoagulant therapy in patients with AF.

- Background: Familial hypercholesterolemia (FH) is an underdiagnosed and undertreated genetic disorder with high risk of premature atherosclerotic cardiovascular disease and death. Clinical decision support (CDS) systems have the potential to aid in the identification and management of patients with FH. Prior studies using computer-based systems to screen patients for FH have shown promising results, but there has been no randomized controlled trial conducted. The aim of the current cluster randomized study is to evaluate if a CDS can increase the identification of FH.Methods: We have developed a CDS integrated in the electronic health records that will be activated in patients with elevated cholesterol levels (total cholesterol > 8 mmol/L or low-density lipoprotein-cholesterol > 5.5 mmol/L, adjusted for age, ongoing lipid lowering therapy and presence of premature coronar y arter y disease) at increased risk for FH. When activated, the CDS will urge the physician to send an automatically generated referral to the local lipid clinic for further evaluation. To evaluate the effects of the CDS, all primary care clinics will be cluster randomized 1:1 to either CDS intervention or standard care in a Swedish region with almost 500,000 inhabitants. The primary endpoint will be the number of patients diagnosed with FH at 30 months. Resource use and long-term health consequences will be estimated to assess the cost-effectiveness of the intervention.Conclusion : Despite increasing awareness of FH, the condition remains underdiagnosed and undertreated. The present study will investigate whether a CDS can increase the number of patients being diagnosed with FH.

- Aims To provide data guiding long-term antithrombotic therapy after coronar y arter y by-pass grafting (CABG) in patients with preoperative atrial fibrillation (AF). Methods and results From the SWEDEHEART registry, we included all patients, between January 2006 and September 2016, with preoperative AF and CHA2DS2-VASC score >2, undergoing CABG. Based on dispensed prescriptions 12 to 18 months after CABG, patients were divided in 3 groups: use of platelet inhibitors (PI) only, oral anticoagulant (OAC) only or a combination of OAC + PI. Outcomes were: Major adverse cardiac and cerebrovascular events (MACCE, [all-cause death, myocardial infarction, or stroke]), net adverse clinical events (NACE, [MACCE or bleeding]) and the individual components of NACE. Inverse probability of treatment weighting was used to adjust for the non-randomized study design. Among 2,564 patients, 1,040 (41%) were treated with PI alone, 1,064 (41%) with OAC alone, and 460 (18%) with PI + OAC. Treatment with PI alone was associated with higher risk for MACCE (adjusted HR 1.43, 95% CI 1.09-1.88), driven by higher risk for stroke and MI, compared with OAC alone. Treatment with PI + OAC, was associated with higher risk for NACE (adjusted HR 1.40, 95% CI 1.06-1.85), driven by higher risk for bleeds, compared with OAC alone. Conclusion In this real-world observational study, a high proportion of patients with AF, undergoing CABG, did not receive a long-term OAC therapy. Treatment with OAC alone was associated with a net clinical benefit, compared with PI alone or PI + OAC. (Am Heart J 2023;257:69-77.)

- Background There are conflicting data on the clinical benefit from early administration of abciximab from a large randomized trial and a registry. However, both sources suggest that a benefit may depend on the baseline risk profile of the patients. We evaluated the role of early abciximab administration in patients with ST-segment-elevation myocardial infarction (STEMI) referred for primary percutaneous coronary intervention stratified by the STEMI Thrombolysis In Myocardial Infarction (TIMI) risk score. Methods A total of 1,650 patients were enrolled into the EUROTRANSFER Registry. One thousand eighty-six patients received abciximab (66%). Abciximab was administered early in 727 patients (EA) and late in 359 patients (LA). We used the TIMI risk score for risk stratification. Patients with scores 3 constituted the high-risk group of 616 patients (56.7%), whereas 470 patients formed the low-risk cohort. Factoring in the timing of the abciximab administration resulted in 4 groups of patients who were compared for mortality at 1 year: EA/high-risk (n = 413); LA/high-risk (n = 203); EA/low-risk (n = 3 14); LA/low-risk (n = 156). Baseline difference was accounted for by means of propensity score. Results In high-risk patients, 1-year mortality was significantly lower with early abcximab compared to late administration (8.7% vs 15.8%; odds ratio 0.51, CI 0.31-0.85, P = .01). In multivariable Cox regression analysis, both early abciximab administration and patients risk profile (TIMI score :3) were identified as independent predictors of 1-year mortality. Conclusions Early abciximab administration before transfer for percutaneous coronary intervention in STEMI shows lower mortality at 1-year follow-up. This effect is confined to patients with higher risk profile as defined by TIMI risk score andgt;= 3.
