You may qualify if

• Male or female ≥40 years of age
• Informed consent
• Two or more of the following risk factors for heart failure:; 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 stem or >70% left anterior descending, circumflex or right coronary artery]); An established diagnosis of diabetes (type 1 or type 2); Persistent or permanent atrial fibrillation (not paroxysmal atrial fibrillation); Previous ischemic or embolic stroke; Peripheral arterial disease (previous surgical or percutaneous revascularisation or a documented stenosis greater than 50% of a major peripheral arterial vessel).; 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).; Regular loop diuretic use (any dose at any dosing interval) for >30 days.; 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).

You can't join if

• Inability to give informed consent e.g., due to significant cognitive impairment
• Previous documented diagnosis of heart failure
• Current 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
