Among 392 HF patients, PH was present in 31% of patients with grade 1, in 37% of patients with grade 2, and in 65% of patients with grade 3 diastolic dysfunction; 54% of all HF patients with PH had a TPG >12 mm Hg, suggesting not only a postcapillary but also an additional precapillary component of PH.
Our data indicate that HF patients with even mild diastolic dysfunction often have PH. Echocardiographic assessment suggest that the presence of PH might not simply be due to increased PCWP, but in part due to a precapillary component
Os nossos dados indicam que os doentes com IC, mesmo com disfunção diastólica ligeira, têm frequentemente PH. A avaliação ecocardiográfica sugere que a presença de PH pode não se dever simplesmente ao aumento do PCWP, mas em parte devido a um componente pré-capilar
