Abstract:
Heart failure with preserved ejection fraction (HFpEF) burden is increasing. Its diagnostic process is challenging and imprecise due to absence of a single diagnostic marker, and the multiparametric echocardiography evaluation needed. Left ventricular (LV) ejection fraction (LVEF) is a limited marker of LV function; thus, allocating HF phenotypes based on LVEF can be misleading. HFpEF encompasses a broad spectrum of causes, and its diagnostic criteria give a central role to echocardiography, a first-line technique with inherent limitations related to ultrasound capabilities. Conversely, cardiac magnetic resonance provides superior anatomic and functional assessment, enabling tissue characterization, offering unprecedented diagnostic precision.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
