Cardiac Magnetic Resonance Tomography for Heart Failure With Preserved Ejection Fraction

The diagnosis of heart failure with preserved ejection fraction has so far been made primarily according to criteria determined by echocardiography, or invasively by measuring the left ventricular filling pressures. Increasingly, CMR is also evaluated with regard to the diagnosis of cardiac insufficiency with preserved pump function.However, it is still unclear which parameters can be used meaningfully for diagnostics.To answer this question, the investigators want to retrospectively evaluate data collected from patients with a clinical indication for CMR and coronary angiography.
