Comprehensive Assessment of Heart Failure with Preserved Ejection Fraction Using Cardiac MRI.

Julián Vega-Adauy, Ozge Ozden Tok, Ahmet Celik, Ahmet Barutcu, Mani A Vannan,

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 ... Read more >>
