Real-world Study on Dapagliflozin Usage in Patients With Heart Failure (HF) in Germany

Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.

Acoramidis Transthyretin Amyloidosis Prevention Trial in the Young (ACT-EARLY) Study in Asymptomatic Carriers of a Pathogenic TTR Variant

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.

Testing VIRTUES Patient Care Sets in Cardiac Patients (VIRTUES Cardiac Care)

Patients with various cardiac conditions (such as those who experience a heart attack) are increasing in Canada and are in need of appropriate cardiac rehabilitation and care. Many patients do not have access to local in-person cardiac clinics, particularly in rural regions of Canada. A user-friendly digital application with accessible educational resources and recommendations based on the most up to date clinical practice guidelines can help mitigate these issues. VIRTUES is a digital healthcare application that targets 11 modifiable modules as follows: 1. antithrombotic management 2. lipid management 3. rate and rhythm control for atrial fibrillation 4. heart failure care 5. post myocardial infarction care 6. blood sugar management 7. blood pressure management 8. physical activity 9. healthy eating 10. smoking cessation 11. alcohol reduction Of the 11 total modules, the first 7 listed provide recommendations in VIRTUES. The remaining 4 (physical activity, healthy eating, smoking cessation and alcohol reduction) consist of simple referrals to existing recommendations (i.e., for healthy eating and physical exercise) and referrals to existing local programs (i.e., for smoking cessation and alcohol reduction). Thus, in this cohort study, the investigators will test the primary 7 modules with 200 patients per module for approximately one month each in order to obtain feedback on the usability of each module. The investigators will also conduct virtual focus group discussions to obtain open ended feedback on the application. This study will provide valuable feedback, which will be used to improve and adapt the VIRTUES platform.

American Indian Chronic Renal Insufficiency Cohort Study (AI-CRIC Study)

Despite many advances in our understanding of the natural history and progression of chronic kidney disease (CKD) and cardio vascular disease (CVD) in the parent CRIC study over the past 15 years, important questions about key risk factors for these diseases remain unanswered in the AI population. To address this burden of CKD in AI communities Investigators formed a consortium of investigators with extensive experience in conducting research of chronic diseases including diabetes, cardiovascular and kidney disease in AIs of Southwestern US. The proposed CRIC ancillary cohort study of 500 AIs (AI-CRIC) will rapidly improve our understanding of both potential risk factors for CKD progression, as well as the scope of this disease among AIs. This study leverages the current CRIC study and incorporates the planned activities of the next phase of the study - "CRIC 2018" - by implementing contemporary CRIC protocols for kidney and cardiovascular measurement and outcomes.

HEARTBiT: Multi-Marker Blood Test for Acute Cardiac Transplant Rejection

Heart transplantation is a life saving therapy for people with end stage heart failure. Acute rejection, a process where the immune system recognizes the transplanted heart as foreign and mounts a response against it, remains a clinical problem despite improvements in immunosuppressive drugs. Acute rejection occurs in 20-30% of patients within the first 3 months post-transplant, and is currently detected by highly invasive heart tissue biopsies that happen 12-15 times in the first year post-transplant. Replacing the biopsy with a simple blood test is of utmost value to patients and will reduce healthcare costs. The goal of our project is to develop a new blood test to monitor heart transplant rejection. Advances in biotechnology have enabled simultaneous measurement of many molecules (e.g., proteins, nucleic acids) in blood, driving the development of new diagnostics. Our team is a leader in using computational tools to combine information from numerous biological molecules and clinical data to generate "biomarker panels" that are more powerful than existing diagnostic tests. Our sophisticated analytic methods has recently derived HEARTBiT, a promising test of acute rejection comprising 9 RNA biomarkers, from the measurement of 30,000 blood molecules in 150 Canadian heart transplant patients. Our objective is to study a custom-built HEARTBiT test in a setting and on a technology that enable clinical adoption. We will evaluate the new test on 400 new patients from 5 North American transplant centres. We will also track patients' HEARTBiT scores over time to help predict future rejection, and explore use of proteins and micoRNAs to improve HEARTBiT. Our work will provide the basis for a future clinical trial. The significance of this work rests in that it will provide a tool to identify acute cardiac rejection in a fast, accurate, cost-effective and minimally invasive manner, allowing for facile long-term monitoring and therapy tailoring for heart transplant patients.

Ablation of Consecutive Atrial Tachycardia

Ablation of consecutive atrial tachycardia (AT) after ablation of atrial fibrillation (AF) or cardiac surgery can be challenging due to complex substrate and AT mechanisms. A substantial portion of patients is known to show various tachycardias and recurrences occur in a noticeable number of cases. With the availability of novel ultra-high-density mapping techniques characterization and understanding of AT mechanisms and underlying substrate can be improved. Aim of this prospective, multi-center, randomized study is to compare a standard AT ablation approach versus minimalized ablation of the clinical AT in regards to arrhythmia free survival.
