Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04591639). This is a study registration, not published results. Lead sponsor: University of Edinburgh. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 81 participants (ACTUAL). Conditions: Heart Failure, Diabetic Cardiomyopathies. Interventions: DRUG: Dapagliflozin 10 milligrams [Farxiga]; DRUG: Placebo. Primary outcome measures: Rate of change in myocardial T1 values with manganese enhanced cardiac MRI , 6 months. Brief summary: Diabetes mellitus is among the top 10 causes of death worldwide with an increasing incidence. Patients with diabetes are at risk of developing heart failure which is characterised by significant changes in the heart muscle including scarring and thickening. Contraction of the heart involves movement of calcium across the heart muscle and disruption of this process is an early change seen in heart failure. Recently, a drug therapy (SGLT2 inhibitor therapy) in patients with diabetes was shown to benefit patients with heart failure but the mechanisms of benefit are unknown. Our hypothesis is that calcium handling is altered in patients with either type 2 diabetes mellitus (T2DM) or heart failure and that SGLT2 inhibitors can improve this in heart failure irrespective of the presence of T2DM. Scanning the heart using magnetic resonance imaging (MRI) enables detailed assessment of its structure and function by using a new contrast 'dye' containing manganese that has shown advantages over traditional contrast. We plan to further test this new dye as it has the potential to track and quantify improvements in heart function over time and detect changes in calcium handling in the heart muscle, making it an ideal measure to identify the mechanisms of benefit from SGLT2 inhibitor therapy. The study population will comprise patients with heart failure with and without type 2 diabetes, patients with type 2 diabetes without heart failure and healthy volunteers. Baseline comparisons will be made between the four groups before progressing to the randomised controlled trial with heart failure patients only. Patients will have a clinical assessment and blood tests, electrocardiogram, echocardiogram and MRI of the heart at each visit. If successful, this study will give us significant insights into mechanisms of action of SGLT2 inhibitors in heart failure and will enable us to tailor specific treatments in heart failure patients.
