Below are current clinical trials.

Filter this list of studies by location, status and more.

1. A Study of Long-Term Outcomes of Cardiac Resynchronization Therapy Recipients with Congestive Heart Failure

   Rochester, Minn.

   The purpose of this study is to determine the long-term outcome of cardiac resynchronization therapy (CRT) recipients with congestive heart failure and any indications for CRT at Mayo Clinic.   

2. A Study to Evaluate NT-proBNP Levels in the Prediction of Intrapartum and Postpartum Events in Adult Congenital Heart Disease Patients

   Rochester, Minn.

   The purpose of this study is to characterize the relationship between NT-proBNP levels obtained at time of admission for delivery and subsequent cardiovascular events in ACHD patients, and to describe normative values for NT-proBNP at time of admission for delivery in an uncomplicated obstetric population.

3. A Study to Evaluate Sex and Age Differences in Ehlers Danlos Syndrome Patients

   Jacksonville, Fla.

   The purpose of this study is to determine whether serum biomarkers and comorbidities differ between subjects with hEDS/HSD vs. other non-hypermobile EDS subtypes and whether sex and/or age differences exist, and to determine whether serum biomarkers and comorbidities differ between subjects with hEDS vs. HSD and whether sex and/or age differences exist.

4. A Study to Evaluate Long-term Outcomes of Alcohol Septal Ablation for Hypertrophic Cardiomyopathy

   Rochester, Minn.

   The purpose of this study is to determine long term vital status, symptoms, and need for repeat procedure after alcohol septal ablation, to determine patient and procedural factors associated with successful alcohol septal ablation and need for repeat procedure, and to determine the impact of conduction abnormalities after alcohol septal ablation on long-term outcomes.

5. A Study to Identify Late-Occurring Complications in Childhood Cancer Survivors

   Rochester, Minn.

   The purpose of this trial is to identify cancer survivors who are at increased risk of developing late-occurring complications after undergoing treatment for childhood cancer. A patient's genes may affect the risk of developing complications, such as congestive heart failure, heart attack, stroke, and second cancer, years after undergoing cancer treatment. Genetic studies may help doctors identify survivors of childhood cancer who are more likely to develop late complications.

6. A Study to Evaluate Potential Myocardial Injury in Patients with Cardiac Implantable Electronic Devices Undergoing Defibrillation Threshold Testing

   Rochester, Minn.

   The purpose of this study is to determine if defibrillation threshold testing (DFT) results in myocardial injury as assessed by changes in high sensitivity cardiac troponin T (hs-cTnT). This will be done by comparing pre-and-post DFT hs-cTnT levels in these patients.

7. Identification of Novel Genetic Variants and Biomarkers of Disease Progression in Arrhythmogenic Cardiomyopathy

   Rochester, Minn.

   The purpose of this study is to identify hereditary causes of cardiomyopathy.

8. Is Our Microbiome a Predictor of Cardiac Risk

   Rochester, Minn.

   The purpose of this study is to compare the fecal microbiota of patients with mild, moderate and severe Coronary Artery Disease (CAD) by collecting stool and blood samples from patients undergoing coronary angiograms.

    

9. A Study of the Mayo Clinic College of Medicine Ultrasound System

   Rochester, Minn.

   The purpose of this study is is to assess the EPIQ-Affiniti and NG Compact ultrasound systems in a clinical environment and collect clinical data and feedback when compared to the site’s standard ultrasound system.

10. A Study to Evaluate Decision-support Interventions for Atrial Fibrillation (RED-AF)

    Rochester, Minn.

    1. The primary purpose of this study is to assess the comparative effectiveness of the following 4 approaches to promote high-quality SDM for at-risk patients with AF:  a PDA alone, (2) an EDA alone, (3) a combination of a PDA and an EDA, and (4) control with neither a PDA nor an EDA.
