Dr. Abdel-Qadir speaks to a patietn

Heart disease remains a leading cause of death in Canada, particularly for women where the condition has been under-researched, under-treated and under-supported. Variability in screening and quality of care impacts the ability of Canadians to live longer lives free from heart disease.

Our scientists are focused on novel cardiovascular risk factors including influenza infections, fertility treatment and chemotherapy to identify individuals at highest risk and inform treatment guidelines. To address the disparities in women’s cardiac health, we are also developing solutions to close the health gap by tackling risk factors and disease prevention through unique lifestyle interventions.

Cardiovascular Outcomes Research Program

Dr. Udell and the Cardiovascular Outcomes Research Program team focuses on studying new treatment strategies in patients with or at risk of coronary heart disease (CHD) and heart failure (HF). In Canada, an estimated 2.6 million adults aged 20 years and older are living with CHD including over half a million with a history of a heart attack. Another approximate 700,000 Canadian adults aged 40 years and older were living with HF. In the US, an estimated 20.1 million adult Americans have CHD and 6 million American adults have HF. The prevalence of both conditions and burden on the health system are projected to increase while outcomes are improving thanks in part to therapeutic advancements.


In Canada, breast cancer remains the most common type of cancer in women, while cardiovascular disease is one of the leading causes of death. Cardiovascular disease is also the leading non-cancer cause of death in breast cancer survivors, who have an increased risk of heart disease and stroke because of their cancer treatments. Dr. Abdel-Qadir’s research and clinical focus is on the cardiovascular health of people who are under-represented in clinical trials, particularly women and people with multiple illnesses that introduce competing risks. His aim is to improve medical care for people who face challenges within our healthcare system due to the complexities of their illnesses and address existing knowledge gaps in cardio-oncology research. By developing better pathways of care, he hopes to identify higher-risk women to address modifiable risks to improve their cardiovascular health, as well as lower-risk women to ensure they are spared unnecessary interventions and doctor visits.

Atrial Fibrillation

Atrial fibrillation is the most common sustained rhythm disorder, with an incidence that increases steadily as people age beyond 65 years. It substantially increases the risk of stroke. Current guidelines call for life-long treatment with blood thinners for most patients aged over 65 years as their stroke risk is estimated to exceed be 1% per year. However, this means that over 90% of patients will not develop a stroke yet will be exposed to the risk of bleeding as well as the cost and inconvenience of life-long blood thinners. Dr. Abdel-Qadir’s research program involves cardiovascular disease in older adults with a focus on stroke prevention in patients with atrial fibrillation. He plans to use population-based data to better predict the risk of stroke in older patients with atrial fibrillation and to investigate alternate methods of stroke prevention.

Heart Failure Outcomes 

Dr. Aleksova’s research focuses on evaluating outcomes in patients living with heart failure and after heart transplantation. She is a local co-investigator for DAPA ACT TIMI-HF, a randomized controlled trial of in-hospital initiation of dapagliflozin, and a local co-investigator for AERIAL, a randomized controlled trial of antiplatelet therapy after heart transplantation. Dr. Aleksova was awarded a CDTRP research innovation grant for current work to appraise the available evidence for COVID-19 vaccination strategies in solid organ transplant recipients for the purposes of creating a living systematic review and rapid guideline recommendations. She is also evaluating outcomes in critically ill patients listed urgently for heart transplantation in national listing organ allocation polices.

Cardiac Imaging 

Dr. Akhtari specializes in advanced cardiac imaging. Apart from clinical practice of general cardiology and multi-modality cardiac imaging, her other areas of interest are prevention, diagnosis, and management of coronary artery disease, particularly in those with underlying inflammatory disease. Her research focuses on improving quality of cardiac care offered to patients with rheumatic disease. She also has an interest in development and evaluation of innovative models of care and healthcare delivery, including evaluation of virtual care in Cardiology.

Dr. Akhtari graduated from Queen’s University School of Medicine and has completed further specialty and subspecialty training in Internal Medicine, Cardiology, and Adult Echocardiography (Level 3 training) at McGill University. She worked as a staff cardiologist at McGill University Health Centre prior to leaving to pursue additional training in Cardiovascular Magnetic Resonance Imaging (Level 3 training) at Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts, as well as certification in Cardiac Computed Tomography (Level 2 training) from Johns Hopkins Bayview Medical Center, Baltimore, Maryland. Most recently, she has completed a Master’s degree in Quality Improvement and Patient Safety at the University of Toronto Institute for Health Policy, Management and Evaluation. She is a fellow of the Royal College of Physicians and Surgeons of Canada, fellow of the American College of Cardiology and a diplomate of the National Board of Echocardiography.

Cardiovascular Disease and Kidney Disease 

Dr. Odutayo’s research focuses on the intersection of cardiovascular disease and kidney disease. He is particularly interested in strategies to reduce cardiovascular risk in people with mild to moderate kidney disease. This research area is important to patients and the health system because cardiovascular disease and kidney disease are leading causes of morbidity and mortality. While these conditions can occur separately, they often coexist, resulting in a cycle of interdependent and progressive decline in function in both organ systems. The co-existence of cardiovascular and kidney disease has therefore been acknowledged as a unique clinical entity known as the “cardiorenal syndrome”, which portends a particularly high risk of ischemic heart disease (IHD), heart failure or end-stage renal disease (ESRD); conditions that all contribute to long term morbidity.

Current Observational Research:

Statins in people with chronic kidney disease

  • Heart failure with reduced ejection fraction as a consequence of ischemic heart disease
  • Biomarkers in heart failure and their role in changes in ventricular structure and function in the population with ischemic heart disease
  • Therapies for heart failure with preserved ejection fraction
  • Acute heart failure

Ischemic heart disease is the leading cause of death worldwide and the primary etiology of heart failure. Identifying which patient will have more benefits between myocardial revascularization or medical therapy alone remains a challenge in ischemic heart disease with reduced ejection fraction. The use of new biomarkers may play an essential role in helping the selection of these patients. Heart failure with preserved ejection is associated with high mortality and morbidity. Except for SGLT2 inhibitors, there is a lack of evidence of therapies capable of reducing mortality in this population

Currently Working On:

  • MASS-VI (HF): Hypotheses, rationale, design, and methods for prognostic evaluation of a randomized comparison between patients with coronary artery disease associated with ischemic cardiomyopathy who undergo medical or surgical treatment
  • Chronic heart failure outcomes: a population-based analysis from a Brazilian institution: A retrospective cohort study in patients with chronic heart failure to investigate outcomes and explore associated risk and prognostic factors. Leadership Role.
  • COVID-19 Vaccination Strategies in Solid Organ Transplant Recipients: A Systematic Review and Network Meta-Analysis

Holly’s research focuses on enhancing the care of our patients and families through quality improvement and patient safety initiatives. As part of the cardiology program, Holly works with our team to develop and evaluate models of care in heart failure, urgent cardiac conditions and virtual care to ensure that we provide excellent care and enhance the patient experience.

Current Projects:

  • Virtual Clinic for Individuals with Stable Coronary Artery Disease (2021-2023) (*only recruiting internally at this time)
    • Funded by the Women’s College Hospital Academic and Medical Services Group Innovation Fund

This project aims to create a virtual clinic for patients with stable coronary artery disease through a team approach, comprised of a cardiologist, nurse practitioner, and pharmacist.  This efficient, convenient and patient-centered model of care will enable us to care for a larger group of patients and reduce the number of unnecessary in-person visits, particularly in view of the current COVID-19 pandemic.  It also allows for patients with stable disease to be able to continue to be followed by a specialist, rather than being discharged to their primary care provider, likely leading to improved patient satisfaction.  Furthermore, it helps provide access to specialist care to those living in remote areas with limited resources.

  • Interprofessional Heart Function Clinic (2020-current) (requires referral from physician and must meet certain criteria)
    • Current evaluation of smaller project with the clinic focused on medication optimization funded by small grant from Novartis inc.

Heart failure (HF) predominantly affects older adults over the age of 65 and is associated with increased risk of death, illness, hospitalization and decreased quality of life. After a recent hospitalization for heart failure, individuals are particularly vulnerable and early assessment by a specialist can reduce the risk of ending back up in hospital.  With the implementation of a team-based heart function clinic at WCH, we will aim to provide short-term timely access to follow up and opportunity for the optimization of medical therapy, which will ultimately reduce risk for returning to hospital, reduce risk for medication errors and improve quality of life. My research focuses on ensuring that we are providing timely evidence-based care and comparing our performance to current guidelines.

Association of Neighborhood-Level Material Deprivation With Atrial Fibrillation Care in a Single-Payer Health Care System: A Population-Based Cohort Study

This study described disparities in access to care for atrial fibrillation in Ontario. Beyond its clinical applicability to people with atrial fibrillation, it sheds insight into what elements of clinical care are widely accessible in a single-payer healthcare system, and which aspects are inequitably accessed. The importance of this paper is highlighted by being published in one of the highest impact Cardiology journals.

Cardiovascular Risk Associated With Ibrutinib Use in Chronic Lymphocytic Leukemia: A Population-Based Cohort Study

Ibrutinib is an important treatment for chronic lymphocytic leukemia but comes with an increased risk of a heart rhythm disorder known as atrial fibrillation. This risk has not been well-quantified in routine clinical use. We showed that ibrutinib use was associated with a nearly two-fold increase in the risk of atrial fibrillation, bleeding, and heart failure but was not associated with a higher risk of stroke or myocardial infarction. The ibrutinib-associated bleeding risk was substantially higher in patients who were also treated with anticoagulation. These population-level data confirm signals from prior clinical trials about risk-benefit ratio of ibrutinib and provide a baseline for future cardiac risk comparisons with second-generation Bruton tyrosine kinase inhibitors.

Evaluation of the Risk of Stroke Without Anticoagulation Therapy in Men and Women With Atrial Fibrillation Aged 66 to 74 Years Without Other CHA2DS2-VASc Factors

This paper studies the risk of stroke and its association with age in men and women aged 66 to 74 years with atrial fibrillation who do not have congestive heart failure, hypertension, diabetes, stroke, or vascular disease. This is a patient group with limited clinical trial data and discrepant recommendations regarding use of anticoagulation therapy. Our findings suggest that anticoagulation therapy is unlikely to yield net clinical benefit in all-comers but is more likely to do so for older individuals.

Characteristics and Outcomes of Women Developing Heart Failure After Early Stage Breast Cancer Chemotherapy: A Population-Based Matched Cohort Study

The prognosis of heart failure (HF) after early-stage breast cancer (EBC) treatment with anthracyclines or trastuzumab was not well-characterized before this study, so that patient counselling was driven by the likelihood of cardiotoxicity without a good appreciation of its consequences. We showed that women developing HF after cardiotoxic EBC chemotherapy have fewer comorbidities than cancer-free women with HF and may have better prognosis that matched HF controls.

Association of Influenza Vaccination With Cardiovascular Risk: A Meta-analysis

In this meta-analysis of 9001 adults who were randomized to influenza vaccination versus matching placebo/standard care, receipt of influenza vaccination was associated with a 34% lower risk of major adverse cardiovascular events — and up to 45% lower risk in those with recent acute coronary syndrome. Given influenza poses an ongoing threat to population health, high-risk patients should be counselled on the cardiovascular benefits of flu vaccines.

Universal flu vaccines: a shot at lifelong cardio protection?

In this Clinical Outlook, we highlight current and future approaches for using influenza vaccination to reduce the risk of atherosclerotic cardiovascular disease and heart failure, building an argument for why flu vaccines are an indispensable tool in the heart disease armamentarium.
