Effects of a Specialized Diabetes and Heart Clinic and Detection of Unrecognized Heart Failure in People With Type 2 Diabetes and Cardiovascular Disease

The goal of this clinical trial is to investigate the effects of a specialized Cardio-Metabolic Clinic (CMC) in people with type 2 diabetes and established cardiovascular disease. The CMC provides integrated and individualized diabetes and cardiovascular care aimed at optimizing medication, lifestyle, and management of related health conditions. Treatment recommendations are supported by a decision-support algorithm combining individual patient information with current clinical guidelines. Echo-CT-ProtecT-2D comprises two parallel studies conducted within the same randomized study population: Study 1 - EchoProtecT-2D focuses on cardiac function and heart failure phenotyping. The main questions are: * Can treatment in the CMC improve heart function at rest and during physical activity compared with usual care? * Can treatment in the CMC reduce systemic inflammation and improve physical function, symptoms, and quality of life? * How common is previously unrecognized heart failure, particularly heart failure with preserved ejection fraction (HFpEF), in this high-risk population? Study 2 - CT-ProtecT-2D focuses on coronary inflammation and atherosclerosis. The main questions are: * Can treatment in the CMC reduce inflammation around the coronary arteries compared with usual care? * Can treatment in the CMC reduce the burden of coronary atherosclerosis compared with usual care? * Can treatment in the CMC lead to favorable changes in the composition and high-risk features of coronary atherosclerotic plaques compared with usual care? Participants will be randomly assigned to either treatment in the CMC or usual care provided by their regular healthcare providers. Participants will: * Have an ultrasound examination of the heart (echocardiography) at rest and during physical activity at baseline and after 12 months * Have a CT scan of the coronary arteries at baseline and after 12 months * Provide blood and urine samples * Complete questionnaires about symptoms and quality of life * Complete a six-minute walk test to assess physical function * If assigned to the CMC, attend additional clinic visits as needed to optimize treatment

Endovascular Ablation of the Right Greater Splanchnic Nerve in Subjects Having HFpEF

The purpose of this clinical study is to evaluate the safety and early effectiveness of a catheter-based procedure that treats a nerve called the right greater splanchnic nerve. The study includes people who have heart failure with preserved ejection fraction (HFpEF). The goal is to learn whether this procedure, performed using the Satera Ablation System, may help improve symptoms and to better understand which patients may benefit most from this treatment in the future.

Intravenous Iron to Improve Symptoms, Quality of Life and Exercise Capacity in HFpEF With Iron Deficiency

This study will investigate whether intravenous (IV) iron improves symptoms, exercise capacity, and quality of life in patients with heart failure with preserved ejection fraction (HFpEF) and iron deficiency. Iron deficiency is common in heart failure and is associated with worse symptoms, reduced physical activity, poorer quality of life, and increased hospitalisation risk. Intravenous iron therapy has demonstrated clinical benefit in patients with heart failure with reduced ejection fraction (HFrEF), but evidence in HFpEF remains limited. ISLE-HFpEF is a prospective, randomised, double-blind, placebo-controlled trial enrolling 150 adults with symptomatic HFpEF and iron deficiency. Participants will be randomised in a 1:1 ratio to receive either intravenous ferric derisomaltose (Monofer) or placebo (0.9% sodium chloride). Participants will undergo baseline assessment, treatment infusion, and 12-week follow-up. The primary outcome is change in 6-minute walk distance at 12 weeks. Secondary outcomes include change in Kansas City Cardiomyopathy Questionnaire (KCCQ) score, physical activity measured using wearable accelerometers, transferrin saturation, NT-proBNP, and New York Heart Association (NYHA) functional class. The study will also evaluate the feasibility and utility of continuous digital monitoring using wearable technologies, including a thigh-worn SENS Motion accelerometer and the Oura Ring, to assess real-world physical activity and cardiovascular physiology throughout the study period.

Clinical Feasibility of Cardiac Neuromodulation Therapy for Heart Failure With Preserved Ejection Fraction

This is an open-label pilot study to evaluate the feasibility of Cardiac Neuromodulation Therapy (CNT) in patients with high blood pressure and heart failure who require dual-chamber pacemaker implantation or replacement. The study will assess blood pressure and heart function at rest and during exercise, with and without CNT, for up to 12 months. Participants will receive the Moderato Plus device and complete scheduled follow-up visits. After study completion, CNT therapy will be discontinued and participants will return to standard medical care.
