Research Focus

Hemodynamics is a state of the continuum, unique to each individual, and represents an intricate and finely balanced relationship between the cardiovascular, neuro-hormonal and autonomic systems. Dr. Shah’s research focuses on resting and exercise augmented hemodynamic, and its impact on outcomes among individuals with a range of cardiovascular conditions. His expertise in the hemodynamic evaluation of adult patients with congenital – structural heart disease and research interest are well aligned. Dr. Shah has established the “invasive hemodynamic evaluation program” at the St Boniface Hospital, the first of its kind in Western Canada. Such evaluation plays a vital role in the diagnosis and management of patients with heart failure with preserved ejection fraction (HFpEF), exercise-induced pulmonary hypertension, stiff left atrial syndrome as well as patients with physical deconditioning. As it is not feasible to evaluate some patients by repeated invasive hemodynamic evaluation to identify interval change or impact of therapeutic interventions; Dr. Shah’s laboratory is exploring various alternative technologies that can provide hemodynamic parameters non-invasively. Recently, Dr. Shah’s laboratory has validated one such non-invasive technology, incorporating total body impedance principles, and will be using it in the forthcoming research projects. Incorporating such approaches, our research program is focusing on developing evidence-based interdisciplinary pathways using hemodynamic evaluation in routine clinical care and management of patients with cardiovascular conditions.

Hemodynamic deterioration leads to multi-organ dysfunction through a range of biochemical alterations at the cellular level. Our research also focuses on identifying these cellular mechanisms that will allow us to understand the involved mechanisms and potential therapeutic targets.


About Ashish H. Shah

Dr. Shah obtained MBBS and MD (Internal Medicine) from the B J Medical College, New Civil Hospital, Gujarat University, Ahmedabad, India. As per the bed capacity, the New civil hospital is the largest hospital in Asia and 3rd in the world. Dr. Shah ranked in the first 100 among 56,000 students appearing for the board exams. He was awarded the national merit scholarship for his medical school years. After working as an assistant professor for 3 years in the New Civil Hospitals, Ahmedabad and Surat, he moved to the UK to pursue further studies. After obtaining the Membership of Royal College of Physicians and Surgeons (MRCP), UK, he obtained “Doctor in Medicine” (MD-Research) from the King’s College London. His research project entitled “vascular endothelial and platelet function in heart failure”.

Dr. Shah completed a fellowship in general and interventional cardiology from the Wales Higher Training program in 2013. He pursued 3 additional years of fellowships in adult congenital, structural and coronary artery disease interventions from the Toronto General Hospital. After working as an interventional cardiologist in the Manchester Royal Infirmary, one of the largest European Adult Congenital Heart Disease centers, he has moved to Winnipeg as an interventional cardiologist. He has joined as a clinician-scientist, with a research focus on “Hemodynamics and Outcomes”.

Current Clinical Role

Dr. Shah joined the Cardiac Sciences Program and the Section of Cardiology as an Academic Clinician Scientist in 2017, where he dedicates a large proportion of time towards translational and clinical research. As a clinician, he is focusing on diagnostic and interventional procedures in patients with coronary, structural and congenital heart diseases.

Current Research Initiatives

Dr. Shah’s research interest in hemodynamic evaluation has inspired novel research projects evaluating cardiogenic shock or identification of hemodynamic parameters among patients presenting with ST-Elevation Myocardial Infarction as well as heart failure. Meticulously designed studies to replicate the pragmatic conditions while assessing the non-invasive hemodynamic measurements to widen the knowledge translation of outcomes to change the clinical practice of such cardiac patients’ management. Our approach focuses on establishing an individual patient-centric “precision medicine” approach with the intention to improvise current clinical care and outcomes.

Furthering Peer-Reviewed Research

Over the last five years, Dr. Shah has also contributed to peer reviewer responsibilities for many scientific journals such as the Canadian Journal of Cardiology, Annals of Internal Medicine, European Heart Journal – Quality of care & clinical outcomes, Heart, Lung & Circulation, Annals of Internal Medicine, and Journal of General Internal Medicine.

Dr. Shah has been invited as a faculty to present his research work in various international conferences, including TCT, CRT, and CSI-UCSF. He is also the recipient of various travel grants to attend and present his work at various international conferences.

Dr. Shah is a member of the Adult Congenital Heart Disease Learning Centre and has played a vital role in preparing various interventional procedural-learning modules.


Dr. Shah has a special interest in BioDesign and innovation. One of his devices focusing on obtaining patent radial hemostasis is under review for the European patent rights.
