Summary

This study evaluates how different non-invasive and invasive measurements reflect left ventricular filling pressure, an important indicator of cardiac function. Elevated filling pressure is associated with symptoms such as shortness of breath and plays a central role in the diagnosis and management of heart failure and pulmonary hypertension. In clinical practice, filling pressure can be estimated using echocardiography or measured during cardiac catheterisation. However, the relationships between these measurements and their ability to accurately reflect true filling pressure are not fully understood. This retrospective study includes patients who underwent cardiac catheterisation with invasive haemodynamic assessment and temporally related echocardiographic evaluation as part of routine clinical care. The aim is to improve understanding of how different measurements relate to each other and to identify which parameters best reflect elevated filling pressure. The results are expected to support more accurate interpretation of haemodynamic measurements and improve clinical decision-making, particularly regarding the use of non-invasive versus invasive assessment.
