Dr. Jassal’s research focuses on the complementary use of multimodality cardiovascular imaging in the non-invasive assessment of heart failure syndromes. Using a combination of echocardiography (ultrasound of the heart), cardiac CT (computed tomography), and CMR (cardiac MRI), the Cardiovascular Imaging Laboratory at St. Boniface Albrechtsen Research Centre is dedicated to translational research in the fields of Cardio-Oncology and Sudden Cardiac Death.
1. FANTAM study (Flaxseed in the mitigation of anthracycline and trastuzumab mediated cardiotoxicity)
Cardio-Oncology is an evolving field that focuses on the prevention, diagnosis, and management of cancer patients who are at risk of developing cardiovascular problems as a result of their cancer treatment. Although the multifaceted treatment approach including radiotherapy, surgical resection, and chemotherapy can lead to remission in breast cancer patients, these methods can lead to harmful cardiotoxic side effects. The introduction of two chemotherapeutic agents, Doxorubicin and Trastuzumab, has led to an increase in overall survival in breast cancer patients in both the adjuvant and metastatic settings. Despite their beneficial effects in reducing tumour proliferation, these two anti-cancer drugs are associated with an increased risk of cardiotoxicity. Nearly 1 in 4 women will develop cardiac complications due to this anti-cancer treatment.
Given the increasing rate of cardiac dysfunction associated with Doxorubicin and Trastuzumab, there is a need to further characterize this damage and mitigate its effects on cardiac health. Approximately 30% of women with breast cancer consume flaxseed in the management of their underlying disease. In addition to its ability to reduce the risk of tumour progression, this nutraceutical agent has potent cardiovascular properties. The FANTAM study is currently evaluating the cardioprotective effects of flaxseed and/or is bioactive components against Doxorubicin and Trastuzumab induced cardiotoxicity.
2. SPARC study (Scleraxis in the prognostication of sudden cardiac death in hypertrophic cardiomyopathy)
Sudden cardiac death (SCD) affects over 40 000 Canadians per year. It is a disease with an array of etiologies, one of which is hypertrophic cardiomyopathy (HCM). HCM affects approximately 0.2% of Canadians and is the leading cause of SCD in the general population. HCM is a genetic condition characterized by cardiac fibrosis, a disease state that leads to progressive deposition of collagen within the myocardium. Over time, cardiac fibrosis alters the stiffness and compliance of the heart, thereby impairing both systolic and diastolic function in HCM patients. Although CMR is the primary imaging modality of choice for detection of fibrosis in HCM, it is limited due to its high costs and low availability throughout Canada. A more cost-effective approach for early screening and risk stratification of HCM patients could involve the development of a serum biomarker for cardiac fibrosis. Scleraxis has been recently identified as a critical regulatory protein for the development of cardiac fibrosis. The underlying goal of the SPARC study is to characterize whether scleraxis, as a biomarker for cardiac fibrosis, is detectable and correlates with disease burden in patients with HCM.
3. RAS-ASICS study (Avastin and Sutent Induced Cardiotoxicity Study)
Colorectal and renal cell cancers are major public health concerns in Canada. An increased understanding of the pathophysiology of these two cancers has led to the development of targeted therapies, including Bevacizumab (BVZ) and Sunitinib (SNT). BVZ is a monoclonal antibody used in the treatment of colorectal cancer, while SNT is a tyrosine kinase inhibitor that suppresses renal cell cancer growth. Despite the effectiveness of these anti-cancer agents, their use is associated with an increased risk of developing cardiotoxicity. Although heart failure medications including renin-angiotensin system (RAS) antagonists are commonly used after cardiac dysfunction is detected in the cancer setting, little is known on their prophylactic role in the prevention of BVZ and SNT mediated cardiac dysfunction. The RAS ASICS study is currently evaluating the cardioprotective effects of RAS inhibitors (Aliskiren, Perindopril, and Valsartan) in the prevention of BVZ and SNT mediated cardiotoxicity.
4. Role of Cardiac CT for Risk Stratification in the Marathon Population
Marathon running has become increasingly more popular over the past two decades in Manitoba and Canada. Although 40,000 individuals participated in Canadian marathons in 1980, this number has increased to a staggering 1.5 million individuals in 2016. The increase in marathon participation has been driven mainly by increased public awareness of the health benefits associated with regular physical exercise. Despite the increased understanding of the acute cardiovascular effects of repeated marathon running, the number of participants who experience sudden cardiac death (SCD) during races continue to make headlines and draw media attention to the concerns regarding health risks associated with marathon running. The objective of this study is to characterize the prevalence of silent coronary artery disease using cardiac computed tomography (CCT) in a marathon population over 40 years of age in Manitoba. This study will provide important data on the prevalence of silent heart disease in the Manitoba marathon population, with the overall goal of incorporating cardiac CT as a simple non-invasive tool for addressing the safety of endurance running in older individuals in Canada.
