Overview

This is a prospective, multicentre, unblinded, randomised, controlled trial. The primary aim is to assess a targeted screening strategy to detect undiagnosed heart failure in high-risk patients with diabetes. Participants will be recruited from the diabetes service in two NHS health boards in Scotland; NHS Greater Glasgow and Clyde and NHS Lanarkshire. At the point of recruitment and consent, patients will be randomised to one of two arms: 1. "Routine care arm" - patients in this arm will undergo routine diabetes care. They will be managed and followed up as per routine clinical care. They will be remotely monitored for HF events electronically. Quality of life questionnaires (Kansas City Cardiomyopathy Questionnaire-12 and EQ-5D) will be completed electronically through CASTOR program in this arm (with the option of paper versions for participants who can not use CASTOR). OR 2. "Investigational arm" - patients in this arm will have a blood sample taken to measure N-terminal prohormone of B-type natriuretic peptide (NT-proBNP) using a Roche assay. In addition to this, blood samples for haemoglobin, creatinine, HbA1c, cholesterol profile, liver function tests and eGFR will be collected. Quality of life questionnaires (Kansas City Cardiomyopathy Questionnaire-12 and EQ-5D) will be completed electronically through CASTOR program in this arm (with the option of paper versions for participants who can not use CASTOR). All patients in this arm will also have an ECG and basic body measurements and observations measured. Further venous blood samples will be collected and stored within Glasgow University storage facilities for future measurement of relevant biomarkers and for use in future ethically approved research. Urine samples will also be collected for measurement of urine albumin:creatinine ratio and for future measurement of relevant biomarkers and use in future ethically approved research. Patients with an elevated Roche NT-proBNP (≥125 pg/mL) will undergo a full cart-based transthoracic echocardiogram along with a clinical examination for signs of HF and a HF symptom assessment. A British Society of Echocardiography minimum dataset will be obtained, and report created. Patients will then also undergo a handheld echocardiogram with a UKCE-marked handheld point of care (POC) EchoNous Kosmos echocardiogram device. The handheld echocardiogram images will be acquired by a British Society of Echocardiography accredited operator. The US2.ai algorithm (which is also UKCE marked) will generate an AI-automated echocardiogram report. Patients who are classified as having heart failure (HFrEF, HFmrEF, or HFpEF) will be managed according to the latest version of European Society of Cardiology guidelines for the diagnosis and treatment of acute and chronic heart failure. The results of the cart-based echocardiogram will be used during the determination of the presence or absence of HF.

NT-proBNP will be measured in all participants in the Investigational arm. If the level of the NT-proBNP is elevated (≥125pg/mL) participants will undergo a full cart-based transthoracic echocardiogram along with a clinical examination for signs of HF and a HF symptom assessment. Participants with HF identified will be referred to their local HF clinic for ongoing management.

Eligibility

Sex: ALLMin age: 40 Years

Medical Language ↔ Plain English

Inclusion Criteria: * Male or female ≥40 years of age * Informed consent * An established diagnosis of diabetes (type 1 or type 2) * At least one additional risk factor for heart failure: 1. Coronary artery disease (either a previous documented type 1 myocardial infarction or coronary artery bypass grafting or percutaneous coronary intervention or documented stenosis of an epicardial coronary artery \[\>50% left main or \>70% left anterior descending, circumflex or right coronary artery\]) 2. Persistent or permanent atrial fibrillation (not paroxysmal atrial fibrillation) 3. Previous ischemic or embolic stroke 4. Peripheral arterial disease (previous surgical or percutaneous revascularisation or a documented stenosis greater than 50% of a major peripheral arterial vessel). 5. Chronic kidney disease (defined as an estimated glomerular filtration rate \<60mL/min/1.73m2 or eGFR 60-90mL/min/1.73m2 and UACR \>300mg/g). 6. Regular loop diuretic use (any dose at any dosing interval) for \>30 days. 7. COPD (evidenced by one of the following; PFTs showing airway obstruction, diagnosis by respiratory physician, CT scan reporting presence of emphysema or treatment with national guideline-advocated COPD therapy). Exclusion Criteria: * Inability to give informed consent e.g., due to significant cognitive impairment. * Previous documented diagnosis of heart failure. * Echocardiogram or NT-proBNP interpreted as excluding heart failure within 12 months. * Currently receiving scheduled renal replacement therapy. * Anyone who, in the investigators' opinion, is not suitable to participate in the trial for other reasons e.g., a diagnosis which may compromise survival over the study period
