Brief Summary
Heart failure with preserved ejection fraction (HFpEF) is a common and growing condition with a poor prognosis but the pathophysiology and management are still being investigated. The PREFER-CMR project aims to evaluate and validate the application of novel 4D cardiac magnetic resonance flow dynamic methods to measure left ventricular pressures and validate these measurements with direct pressure measurement by coronary angiography. This is a prospective observational study of patients with HFpEF undergoing clinical evaluation with coronary angiography who will also undergo contemporaneous cardiac MRI. The primary outcome will be the level of agreement between the two methods using angiography as the reference method.

Outcome Measures
Primary Outcomes (1)
Left ventricular pressure measured by invasive angiography (reference method) and modelled by cardiovascular magnetic resonance imaging
Agreement of invasively measured left ventricular pressure in millimeters of mercury (mmHg) by invasive angiography to non-invasively modelled left ventricular pressure by cardiac magnetic resonance imaging. The agreement will be tested by Bland-Altman plots..
30 days
Secondary Outcomes (1)
Prognostic relevance of left ventricular pressures measured by cardiac MRI
Ten years
Study Arms (2)
HFpEF group
Suspected HFpEF group: 80 patients will be recruited with history of dyspnoea, LV ejection fraction ≥ 50%, raised NTproBNP
Control group
20 patients with suspected CAD but with no dyspnoea and normal echocardiogram.
Interventions
Research based Cardiac MRI evaluation to determine cardiovascular haemodynamics
Eligibility Criteria
* Suspected heart failure patients * Suspected coronary artery disease patients
You may qualify if:
- Adults: age≥18 years.
- Typical HF symptoms (NYHA stage\>I) within the last six months.
- Raised NTproBNP (\>400 pg/ml)
- EF\>50 % with the absence of structural heart disease on TTE (except left ventricular hypertrophy or left atrial enlargement).
You may not qualify if:
- Patients unable/unwilling to provide informed consent.
- Bodyweight\>120 kg or inability to lie flat/still.
- Contraindication for invasive workup (allergy to contrast, severe renal insufficiency with estimated glomerular filtration rate (eGRF)\<30 ml/min).
- Contraindications for a contrast-enhanced CMR study (allergy to contrast, incompatible devices or implants, severe claustrophobia).
- Previous medical history of EF \<50%
- Pregnancy
- The extended observational arm of the study will have wider eligibility criteria
- \- Patients undergoing cardiac MRI for clinical indications irrespective of EF
