  • 2023
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 262, s. 110-118

    • Background: Despite proven benefits of exercise-based cardiac rehabilitation (EBCR), few patients with myocardial infarction (MI) participate in and complete these programs.Study design and objectives: The Remote Exercise SWEDEHEART study is a large multicenter registry-based cluster randomized crossover clinical trial with a planned enrollment of 1500 patients with a recent MI. Patients at intervention centers will be offered supervised EBCR, either delivered remotely, center-based or as a combination of both modes, as self -preferred choice. At control centers, patients will be offered supervised center-based EBCR, only. The duration of each time period (intervention/control) for each center will be 15 months and then cross-over occurs. The primary aim is to evaluate if remotely delivered EBCR, offered as an alternative to center-based EBCR, can increase participation in EBCR sessions. The proportion completers in each group will be presented in a supportive responder analysis. The key secondary aim is to investigate if remote EBCR is as least as effective as center-based EBCR, in terms of physical fitness and patient-reported outcome measures. Follow-up of major adverse cardiovascular events (cardiovascular-and all-cause mortality, recurrent hospitalization for acute coronary syndrome, heart failure hospitalization, stroke, and coronary revascularization) will be performed at 1 and 3 years. Safety monitoring of serious adverse events will be registered, and a cost-effectiveness analysis will be conducted to estimate the cost per quality-adjusted life-year (QALY) associated with the intervention compared with control.Conclusions: The cluster randomized crossover clinical trial Remote Exercise SWEDEHEART study is evaluating if par-ticipation in EBCR sessions can be increased, which may contribute to health benefits both on a group level and for individual patients including a more equal access to health care.Trial registration The study is registered atClinicalTrials.gov (Identifier: NCT04260958) (Am Heart J 2023;262:110-118.)

  • The Full Revasc (Ffr-gUidance for compLete non-cuLprit REVASCularization) Registry-based randomized clinical trial
  • 2021
  • Ingår i: American Heart Journal. - : Elsevier. - 0002-8703 .- 1097-6744. ; 241, s. 92-100
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Complete revascularization in ST elevation myocardial infarction (STEMI) patients with multivessel disease has resulted in reduction in composite clinical endpoints in medium sized trials. Only one trial showed an effect on hard clinical endpoints, but the revascularization procedure was guided by angiographic evaluation of stenosis severity. Consequently, it is not clear how Fractional Flow Reserve (FFR)-guided percutaneous coronary intervention (PCI) affects hard clinical endpoints in STEMI. Methods and Results The Ffr-gUidance for compLete non-cuLprit REVASCularization (FULL REVASC) - is a pragmatic, multicenter, international, registry-based randomized clinical trial designed to evaluate whether a strategy of FFR-guided complete revascularization of non-culprit lesions, reduces the combined primary endpoint of total mortality, non-fatal MI and unplanned revascularization. 1,545 patients were randomized to receive FFR-guided PCI during the index hospitalization or initial conservative management of non-culprit lesions. We found that in angiographically severe non-culprit lesions of 90-99% severity, 1 in 5 of these lesions were re-classified as non-flow limiting by FFR. Considering lesions of intermediate severity (70%-89%), half were re-classified as non-flow limiting by FFR. The study is event driven for an estimated follow-up of at least 2.75 years to detect a 9.9%/year >7.425%/year difference (HR = 0.74 at 80% power (alpha = .05)) for the combined primary endpoint. Conclusion This large randomized clinical trial is designed and powered to evaluate the effect of complete revascularization with FFR-guided PCI during index hospitalization on total mortality, non-fatal MI and unplanned revascularization following primary PCI in STEMI patients with multivessel disease. Enrollment completed in September 2019 and follow-up is ongoing.

  • Use of surgery in patients with native valve infective endocarditis: results from the International Collaboration on Endocarditis Merged Database.
  • 2005
  • Ingår i: American heart journal. - : Elsevier BV. - 1097-6744 .- 0002-8703. ; 150:5, s. 1092-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Early surgery has been shown to be beneficial for patients with infective endocarditis (IE), yet surgery is not used in most patients. Evidence of the uncertainty around the use of surgery can be found in the wide variations in the use of cardiac surgery in IE with few precise indications for cardiac surgery yet defined. The aim of the study was to characterize patients with native valve IE relative to surgery and to determine if patients who benefit from an early surgical intervention can be identified. METHODS: The International Collaboration on Endocarditis Merged Database was used to quantify the differences between patients with IE receiving medical and surgical intervention in 1516 patients with definite native valve IE. Propensity models were built to identify a group of patients that benefit from early surgery. RESULTS: Patients in the early surgical group were more likely to be male, younger, and with less comorbidities compared with the early medical group (P < .001 for all) and were less likely to have infection with Staphylococcus aureus or viridans group streptococci (P < .05 for all). Intracardiac abscess and heart failure were much more common in the surgical group (P < .001 for all). In an unadjusted comparison, there was no statistically significant survival advantage in the surgical group. However, in the propensity analysis, in the subgroup of patients with the most indications for surgery, there was a significant decrease in mortality associated with early surgery (11.2% vs 38.0%, P < .001). CONCLUSIONS: The benefits of surgery are not seen uniformly in all patients with native valve IE, but are most realized in a targeted population. This observation requires confirmation in other populations of patients with definite IE.

  • Thrombus aspiration in patients with large anterior myocardial infarction : A Thrombus Aspiration in ST-Elevation myocardial infarction in Scandinavia trial substudy
  • 2016
  • Ingår i: American Heart Journal. - : Elsevier. - 0002-8703 .- 1097-6744. ; 172:2, s. 129-134
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The TASTE trial did not demonstrate clinical benefit of thrombus aspiration (TA). High-risk patients might benefit from TA.Methods: The TASTE trial was a multicenter, randomized, controlled, open-label trial obtaining end points from national registries. Patients (n = 7,244) with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) were randomly assigned 1: 1 to TA and PCI or to PCI alone. We assessed the 1-year clinical effect of TA in a subgroup with potentially large anterior STEMI: mid or proximal left anterior descending coronary artery infarct lesion, thrombolysis in myocardial infarction 0 to 2 flow, and symptom onset to PCI time = 5 hours. In this substudy, patient eligibility criteria corresponded to that of the INFUSE-AMI study.Results: In total, 1,826 patients fulfilled inclusion criteria. All-cause mortality at 1 year of patients randomized to TA did not differ from those randomized to PCI only (hazard ratio [HR] 1.05, 95% CI 0.74-1.49, P = .77). Rates of rehospitalization for myocardial infarction, heart failure, and stent thrombosis did not differ between groups (HR 0.87, 95% CI 0.51-1.46, P = .59; HR 1.10 95% CI 0.77-1.58, P = .58; and HR 0.75, 95% CI 0.30-1.86, P = .53, respectively). This was also the case for the combined end point of all-cause mortality and rehospitalization for myocardial infarction, heart failure, or stent thrombosis (HR 1.00, 95% CI 0.79-1.26, P = .99).Conclusion: In patients with STEMI and large area of myocardium at risk, TA did not affect outcome within 1 year.

  • Improved adherence to Swedish national guidelines for acute myocardial infarction : the Quality Improvement in Coronary Care (QUICC) study
  • 2006
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 152:6, s. 1175-1181
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The adherence to evidence-based treatment guidelines for acute myocardial infarction (AMI) is still suboptimal. Therefore, we designed a study to evaluate the effects of a collaborative quality improvement (QI) intervention on the adherence to AMI guidelines. The intervention used a national web-based quality registry to generate local and regular real-time performance feedback. METHODS: A 12-month baseline measurement of the adherence rates was retrospectively collected, comprising the period July 1, 2001, through June 30, 2002. During the intervention period of November 1, 2002, through April 30, 2003, multidisciplinary teams from 19 nonrandomized intervention hospitals were subjected to a multifaceted QI-oriented intervention. Another 19 hospitals, unaware of their status as controls, were matched to the intervention hospitals. During the postintervention measurement period of May 1, 2003, through April 30, 2004, a total of 6726 consecutive patients were included at the intervention (n = 3786) and control (n = 2940) hospitals. The outcome measures comprised 5 Swedish national guideline-derived quality indicators, compared between baseline and postintervention levels in the control and QUICC intervention hospitals. RESULTS: In the control and QI intervention hospitals, the mean absolute increase of patients receiving angiotensin-converting enzyme inhibitors was 1.4% vs 12.6% (P = .002), lipid-lowering therapy 2.3% vs 7.2% (P = .065), clopidogrel 26.3% vs 41.2% (P = .010), heparin/low-molecular weight heparin 5.3% vs 16.3% (P = .010), and coronary angiography 6.2% vs 16.8% (P = .027), respectively. The number of QI intervention hospitals reaching a treatment level of at least 70% in 4 or 5 of the 5 indicators was 15 and 5, respectively. In the control group, no hospital reached 70% or more in just 4 of the 5 indicators. CONCLUSIONS: By combining a systematic and multidisciplinary QI collaborative with a web-based national quality registry with functionality allowing real-time performance feedback, major improvements in the adherence to national AMI guidelines can be achieved.

  • Individual Patient Data from the Pivotal Randomized Controlled Trials of Non-Vitamin K Antagonist Oral Anticoagulants in Patients with Atrial Fibrillation (COMBINE AF) : Design and Rationale
  • 2021
  • Ingår i: American Heart Journal. - : Elsevier. - 0002-8703 .- 1097-6744. ; Mar:233, s. 48-58
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Non-vitamin K antagonist oral anticoagulants (NOACs) are the preferred class of medications for prevention of stroke and systemic embolism in patients with atrial fibrillation unless contraindications exist. Five large, international, randomized, controlled trials of NOACs versus either warfarin or aspirin have been completed to date.DESIGN: COMBINE AF incorporates de-identified individual patient data from 77,282 patients with atrial fibrillation at risk for stroke randomized to NOAC, warfarin, or aspirin from 5 pivotal randomized controlled trials. All patients randomized in the constituent trials are included. Variables common to ≥3 of the constituent trials are included in the master database. Individual trial data sets from the 4 coordinating centers were combined at the Duke Clinical Research Institute. The final database will be securely shared with the 4 academic coordinating centers. The combined master database will be used to perform statistical analyses aimed at better understanding underlying risk factors and outcomes in patients with atrial fibrillation treated with oral anticoagulants, with a special focus on patient subgroups and uncommon outcomes. The initial analysis from COMBINE AF will be a network meta-analysis investigating the relative efficacy and safety of pooled higher-dose NOACs versus pooled lower-dose NOACs versus warfarin with respect to multiple time-to-event efficacy and safety outcomes. COMBINE AF is registered with PROSPERO (CRD42020178771).CONCLUSIONS: In conclusion, COMBINE AF provides a rich and robust database consisting of individual patient data and will offer opportunities to investigate oral anticoagulants across many patient subgroups. Data sharing and collaboration across academic institutions and investigators will serve as overarching themes.

  • Anticoagulant therapy and outcomes in patients with prior or acute heart failure and acute coronary syndromes : Insights from the APixaban for PRevention of Acute ISchemic Events 2 trial
  • 2015
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 169:4, s. 531-538
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Clinical outcomes and the effects of oral anticoagulants among patients with acute coronary syndrome (ACS) and either a history of or acute heart failure (HF) are largely unknown. We aimed to assess the relationship between prior HF or acute HF complicating an index ACS event and subsequent clinical outcomes and the efficacy and safety of apixaban compared with placebo in these populations. Methods High-risk patients were randomly assigned post-ACS to apixaban 5.0 mg or placebo twice daily. Median follow-up was 8 (4-12) months. The primary outcome was cardiovascular death, myocardial infarction, or stroke. The main safety outcome was thrombolysis in myocardial infarction major bleeding. Results Heart failure was reported in 2,995 patients (41%), either as prior HF (2,076 [28%]) or acute HF (2,028 [27%]). Patients with HF had a very high baseline risk and were more often managed medically. Heart failure was associated with a higher rate of the primary outcome (prior HF: adjusted hazard ratio [HR] 1.73, 95% CI 1.42-2.10, P < .0001, acute HF: adjusted HR 1.65, 95% CI 1.35-2.01, P < .0001) and cardiovascular death (prior HF: HR 2.54, 95% CI 1.82-3.54, acute HF: adjusted HR 2.52, 95% CI 1.82-3.50). Patients with acute HF also had significantly higher rates of thrombolysis in myocardial infarction major bleeding (prior HF: adjusted HR 1.22, 95% CI 0.65-2.27, P = .54, acute HF: adjusted HR 1.78, 95% CI 1.03-3.08, P = .04). There was no statistical evidence of a differential effect of apixaban on clinical events or bleeding in patients with or without prior HF; however, among patients with acute HF, there were numerically fewer events with apixaban than placebo (14.8 vs 19.3, HR 0.76, 95% CI 0.57-1.01, interaction P = .13), a trend that was not seen in patients with prior HF or no HF. Conclusions In high-risk patients post-ACS, both prior and acute HFs are associated with an increased risk of subsequent clinical events. Apixaban did not significantly reduce clinical events and increased bleeding in patients with and without HF; however, there was a tendency toward fewer clinical events with apixaban in patients with acute HF.

  • Prior smoking status, clinical outcomes, and the comparison of ticagrelor with clopidogrel in acute coronary syndromes-Insights from the PLATelet inhibition and patient Outcomes (PLATO) trial
  • 2012
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 164:3, s. 334-342
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Habitual smoking has been associated with increased platelet reactivity, increased risk of thrombotic complications and greater efficacy of clopidogrel therapy over placebo. In the PLATO trial, ticagrelor compared to clopidogrel in patients with acute coronary syndromes (ACS) reduced the primary composite end point of vascular death, myocardial infarction and stroke, without increasing overall rates of major bleeding. We evaluated the results in relation to smoking habits.Methods Interactions between habitual smokers (n = 6678) and in ex/nonsmokers (n = 11,932) and the effects of randomized treatments on ischemic and bleeding outcomes were evaluated by Cox regression analyses.Results Habitual smokers had an overall lower risk profile and more often ST-elevation ACS. After adjustment for baseline imbalances, habitual smoking was associated with a higher incidence of definite stent thrombosis (adjusted HR, 1.44 [95% CI, 1.07-1.94]); there were no significant associations with other ischemic or bleeding end points. The effects of ticagrelor compared to clopidogrel were consistent for all outcomes regardless of smoking status. Thus, there was a similar reduction in the primary composite end point for habitual smokers (adjusted HR, 0.83 [95% CI, 0.68-1.00]) and ex/nonsmokers (adjusted HR, 0.89 [95% CI, 0.79-1.00]) (interaction P = .50), and in definite stent thrombosis for habitual smokers (adjusted HR, 0.59 [0.39-0.91]) and ex/nonsmokers (adjusted HR, 0.69 [95% CI, 0.45-1.07]) (interaction P = .61).Conclusions In patients hospitalized with ACS, habitual smoking is associated with a greater risk of subsequent stent thrombosis. The reduction of vascular death, myocardial infarction, stroke, and stent thrombosis by ticagrelor compared to clopidogrel is consistent regardless of smoking habits.

  • Prospective Urban Rural Epidemiology (PURE) study: Baseline characteristics of the household sample and comparative analyses with national data in 17 countries
  • 2013
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 166:4
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The PURE study was established to investigate associations between social, behavioural, genetic, and environmental factors and cardiovascular diseases in 17 countries. In this analysis we compare the age, sex, urban/rural, mortality, and educational profiles of the PURE participants to national statistics. METHODS: PURE employed a community-based sampling and recruitment strategy where urban and rural communities were selected within countries. Within communities, representative samples of adults aged 35 to 70 years and their household members (n = 424,921) were invited for participation. RESULTS: The PURE household population compared to national statistics had more women (sex ratio 95.1 men per 100 women vs 100.3) and was older (33.1 years vs 27.3), although age had a positive linear relationship between the two data sources (Pearson's r = 0.92). PURE was 59.3% urban compared to an average of 63.1% in participating countries. The distribution of education was less than 7% different for each category, although PURE households typically had higher levels of education. For example, 37.8% of PURE household members had completed secondary education compared to 31.3% in the national data. Age-adjusted annual mortality rates showed positive correlation for men (r = 0.91) and women (r = 0.92) but were lower in PURE compared to national statistics (7.9 per 1000 vs 8.7 for men; 6.7 vs 8.1 for women). CONCLUSIONS: These findings indicate that modest differences exist between the PURE household population and national data for the indicators studied. These differences, however, are unlikely to have much influence on exposure-disease associations derived in PURE. Further, incidence estimates from PURE, stratified according to sex and/or urban/rural location will enable valid comparisons of the relative rates of various cardiovascular outcomes across countries.
