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. Survival was not related to the severity of diastolic dysfunction , but was worse in patients with PH ( hazard ratio 1.63 , 95 % confidence interval 1.07-2 .51 ; P = .024 ) .
