Data Collection - Atrial Fibrillation Exploratory Study
Rochester, MN
The purpose of this study is to characterize the impact of Atrial fibrillation (AFib) and Atrial Flutter (AFl) on signals measured using a wearable Insertable Cardiac Monitor (ICM) prototype device.

A Study to Evaluate Potential Myocardial Injury Following Elective Direct Current Cardioversion
Rochester, MN
The purpose of this study is to prospectively determine if direct current cardioversion (DCCV) results in myocardial injury as assessed by changes in high sensitivity cardiac troponin T (hs-cTnT) assay.

New-onset Atrial Fibrillation and Flutter Following Cardiac Surgery
Rochester, MN
The aims of this investigation are:
To assess the predictive value (and accuracy) of clinical and physiologic preoperative variables in identifying patients at risk for the development of new-onset atrial arrhythmia after cardiac surgery.
To assess the feasibility of a physiological risk model based on clinical and echocardiographic indexes to predict post-operative AF.
To assess the role of prophylactic agents in the prevention of new-onset postoperative POAF
To assess the economic impact of new-onset postoperative AF:
-
Length of hospital stay (will be measured as fractions of days)
-
Hospital cost (will be measured in standardized dollars)
-
Resource utilization (will be measured by resource-based relative-value units)
To assess the outcome ...

A Study to Analyze Association of Frequent Premature Ventricular Complex with Stroke or Transient Ischemic Attack
Rochester, MN
The purpose of this study is to verify that high Premature Ventricular Complex (PVC) burden is associated with increased risk of stroke and/or Transient Ischemic Attack (TIA), to examine outcomes such as stroke/TIA, atrial fibrillation/flutter, and all-cause mortality associated with PVCs, and to evaluate whether PVCs are associated with development of appendage dysfunction.

Anticoagulation in ICH Survivors for Stroke Prevention and Recovery
Jacksonville, FL
The primary purpose of this study is to determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF).

A Study of Silent Cerebral Lesions in Patients Undergoing Left Heart Ablation for Ventricular Arrhythmia and Atrial Fibrillation
Rochester, MN
The purpose of this study is to learn about the effect of atrial fibrillation on memory and thinking. This study helps us to determine how often memory problems occur in patients with atrial fibrillation and identify factors that influence changes in memory and thinking.
