METABOLIC SYNDROME Cohort Study
A prospective cohort study in patients with diabetes, evaluating the capacity of Tissue mapping and strain analysis by MRI to identify patients with early cardiomyopathy.

VOLTAGES (Pre-CRT/D) – Voltage gradient to identify scar
A prospective study examining the ability of high resolution ECG to detect regional myocardial scar and lack of biventricular capture among patients referred for CRT. A study partnered with Dr Derek Exner's research lab.
A prospective multi-centre cohort study evaluating the prognostic utility of CMR measures in patients with acute myocarditis.
SIGNALS (High-resolution Holter)
A study examining the relationship between ECG signals with a high resolution Holter monitor during two rest periods and a 6-minute walk and the size and function of the heart. A study partnered with Dr Derek Exner's research lab.
CHRONIC IRON DEPOSITION PREDICTION OF ARRHYTHMIC EVENTS
A prospective cohort study of patients with prior myocardial infarction to identify chronic iron deposition related to peri-infarction hemorrhage and its prognostic value for future arrhythmic events. This study is partnered with Cedars-Sinae Medical Centre in LA (Dr Rohan Dharmakumar)
3D SPECKLE TRACKING ECHOCARDIOGRAPHY FOR THE EVALUATION OF RIGHT VENTRICULAR DISEASE
A group studies led by Dr Nowell Fine evaluating 3D echocardiography for the detection and quantification of RV dysfunction. This is partnered with Dr Satriano with cross-validation to 4D CMR-based strain analysis.
3T VERSUS 1.5T T1 MAPPING Study
Healthy volunteer study to characterize both SASHA and ShMOLLI based mapping techniques at 1.5 and 3T
4D CT-BASED AORTIC STRAIN ANALYSIS IN PATIENTS WITH AORTIC STENOSIS
A retrospective cohort study evaluating the capacity of 4D strain analysis from cardiac-gated CTA to identify aortopathy (aortic strain) and to evaluate markers of LV decompensation (LV strain)
Studies the Stephenson Cardiac Imaging Centre is participating in
Alberta Heart Study
A prospective multi-centre study to develop the new diagnostic criteria for diastolic heart failure, including imaging, biomarkers, and vascular physiology. The MRI sub-study is a partnered effort between Edmonton (PI: Richard Thompson) and the Stephenson Cardiac Imaging Centre.
A multi-centre randomized controlled trial and registry of patients with ischemic heart failure, randomized to routine care vs advanced imaging (MRI or PET). QA Core lab at Stephenson Cardiac Imaging Centre.
A multi-centre randomized controlled trial and registry of patients with non-ischemic heart failure, randomized to an echocardiogram only versus echocardiogram along with MRI.
A multi-centre, multi-national study evaluating the diagnostic accuracy and prognostic utility of stress perfusion MRI.
HCM Registry (Novel Predictors of Outcome in Hypertrophic Cardiomyopathy)
The aim of this study is to develop a predictive model of cardiovascular outcomes in hypertrophic cardiomyopathy (HCM) by: 1) using exploratory data mining methods to identify demographic, clinical, and novel cardiac magnetic resonance imaging, genetic and biomarker variables associated with the outcomes and 2) develop a score from the predictive model that can be used to assess risk given a patient’s combination of risk factors, thus establishing the evidence base to enable clinical trial design to reduce morbidity and mortality in HCM in a cost- effective manner.
