Swedeheart registry

The Swedeheart registry is a Swedish clinical quality registry for cardiology that collects detailed data on myocardial infarction, acute coronary syndrome, coronary artery bypass grafting, percutaneous coronary intervention, and related cardiovascular care. It supports national quality improvement initiatives involving institutions such as Karolinska University Hospital, Sahlgrenska University Hospital, Uppsala University Hospital, Linköping University Hospital, and Skåne University Hospital. The registry underpins research collaborations with organizations like Swedish National Board of Health and Welfare, Swedish Heart-Lung Foundation, European Society of Cardiology, American Heart Association, and universities including Uppsala University, Lund University, Karolinska Institutet, and Göteborg University.

Overview

Swedeheart functions as an integrated platform linking clinical data from inpatient and outpatient episodes across Swedish regions such as Stockholm County, Västra Götaland County, Skåne County, Uppsala County, and Örebro County with national registries including National Patient Register (Sweden), Cause of Death Register (Sweden), and Prescribed Drug Register (Sweden). It aggregates procedural datasets that interact with device records from manufacturers aligned with institutions like GE Healthcare, Philips Healthcare, and Medtronic. The registry informs guideline implementation promoted by European Society of Cardiology and national recommendations from Swedish National Board of Health and Welfare while enabling benchmarking against registries such as National Cardiovascular Data Registry and Myocardial Ischaemia National Audit Project.

History and Development

The registry traces origins to quality initiatives in Swedish cardiology during the 1990s and early 2000s led by clinicians at Karolinska Institutet, Lund University, and Uppsala University. Early pilots involved collaborations with regional hospitals including Sahlgrenska University Hospital and Norrlands Universitetssjukhus, and leveraged national infrastructure such as the Swedish National Patient Register. Expansion accelerated with support from funders like Swedish Heart-Lung Foundation and research councils including the Swedish Research Council, and policy endorsements from Swedish National Board of Health and Welfare. International interfaces were developed to align with projects by European Society of Cardiology, World Health Organization, and comparative studies with Danish National Patient Registry and Norwegian Myocardial Infarction Register.

Scope and Coverage

Swedeheart covers acute and chronic presentations across settings in Sweden, from tertiary centers like Karolinska University Hospital to regional hospitals such as Södersjukhuset, Vöstmanlands sjukhus, and community hospitals in counties like Jämtland County and Västerbotten County. Patient-level data include admissions, procedures, device implantations, pharmacotherapy, and outcomes used by clinical networks including Swedish Association of Local Authorities and Regions and specialty societies like Swedish Society of Cardiology. The registry contributes data to multicenter trials coordinated with institutions such as Massachusetts General Hospital, University of Oxford, Johns Hopkins Hospital, and Imperial College London.

Data Collection and Variables

Data elements include demographics, comorbidities, index event characteristics, procedural details for percutaneous coronary intervention, coronary artery bypass grafting, and device therapies like implantable cardioverter-defibrillator implantation, pharmacological treatments including atenolol, metoprolol, simvastatin, and outcomes such as readmission and mortality recorded in Cause of Death Register (Sweden). Variables mirror definitions used by organizations like European Society of Cardiology, American College of Cardiology, Society for Cardiovascular Angiography and Interventions, and integrate coding systems such as ICD-10, ATC classification system, and national identifiers used by Swedish Tax Agency. Data capture workflows incorporate electronic health records from vendors including Cambio Healthcare Systems, Cerner, and Epic Systems to populate case report forms standardized with input from experts at Karolinska Institutet and Uppsala University.

Governance and Ethical Oversight

Governance structures include steering committees with representatives from Swedish Society of Cardiology, regional health authorities such as Stockholm County Council, ethics review by regional Swedish Ethical Review Authority, and data protection compliance aligned with General Data Protection Regulation standards implemented by European Commission guidance. Funding and oversight involve stakeholders including Swedish National Board of Health and Welfare, Swedish Research Council, and foundations such as Erling-Persson Family Foundation. Data access policies govern linkage with registries like National Patient Register (Sweden) and international collaborations with institutions including Karolinska Institutet and Lund University Hospital.

Research Findings and Impact

Analyses from the registry have informed outcomes research on reperfusion strategies for ST-elevation myocardial infarction, comparative effectiveness of primary percutaneous coronary intervention versus fibrinolysis, temporal trends in pharmacotherapy including statins and antiplatelet agents, and quality metrics influencing care at Karolinska University Hospital, Sahlgrenska University Hospital, and regional networks. Publications using Swedeheart data have influenced guidelines from European Society of Cardiology and policy at Swedish National Board of Health and Welfare, and supported multicenter trials with partners such as University of Oxford, Harvard Medical School, Johns Hopkins University, Mayo Clinic, and Duke University Medical Center. Results have also been incorporated into comparative studies with registries like National Cardiovascular Data Registry and Myocardial Ischaemia National Audit Project.

Limitations and Challenges

Limitations include variable data completeness across sites such as smaller hospitals in Norrbotten County and Gotland County, potential biases when linking to administrative sources like National Patient Register (Sweden), and challenges in harmonizing definitions with international partners including Danish National Patient Registry and Norwegian Myocardial Infarction Register. Other challenges involve interoperability with vendors like Epic Systems and Cerner, funding sustainability dependent on bodies like Swedish Research Council and Swedish National Board of Health and Welfare, and ensuring compliance with General Data Protection Regulation during multicenter collaborations with institutions such as University of Oxford and Harvard Medical School.
