HFpEF (heart failure with preserved ejection fraction) is a condition in which the heart muscle becomes stiff and can't pump blood properly. People living with HFpEF also often have coronary artery disease, where the blood vessels that supply the heart are narrowed or blocked. It is not yet know whether opening these arteries with stents improves symptoms or quality of life with HFpEF. REPRIEVED is a randomised clinical trial that aims to find out if heart stents can improve quality of life for people living with heart failure with preserved ejection fraction (HFpEF) and coronary artery disease. Researchers will compare two groups of people; those who have a stent procedure to those who have a placebo procedure. The placebo procedure feels the same as a stent procedure but does not include a stent. 350 people with HFpEF and coronary artery disease will be asked to take part. Participants will be monitored over a period of 6 months to see if and how quality of life changes. Before the procedure, participants will be asked to complete a short health questionnaire, have a blood test, undergo an electrocardiogram (heart tracing) and scans of their heart. On the day of the procedure, the participant will come to the hospital for an angiogram and will be randomly allocated to have either treatment with a stent or the placebo procedure without a stent. Participants will not know whether they have received heart stents. This helps researchers know that any improvements in their quality of life are not just related to how they feel about the stenting treatment. Participants will then be contacted by a member of the research team at 3 months and 6 months after their procedure. At 3 months, participants will complete a short health questionnaire either by phone or during a hospital visit. At 6 months, participants will attend the hospital to complete a short health questionnaire, have blood tests, a scan of the heart (echocardiogram) and an electrocardiogram (heart tracing) to measure any changes in the heart. Participants will be told whether they received the stent procedure or the placebo procedure.
