3
Background I RHC Is the gold standard in PH diagnosis
Classifies PH into 2 groups Galie et al, Eur Heart J 2015
4
Background II Provides information on prognosis SvO2 <65%
RAP >8mmHg CI <2ml/min/m2
5
Background IIΙ Limited number of clinical trials with hemodynamic endpoints (CHEST-1, PATENT-1, SERAPHIN, ATHENA-1, MAESTRO sub-study) Limited follow up period (3 to 6 months) PAH targeted therapies do not improve prognosis-related hemodynamic parameters in most trials
6
Aim To evaluate the effect of advanced PAH treatment on hemodynamic profile of patients with precapillary PH
7
Materials and methods – study design
Retrospective Non invasive Single center AHEPA university Hospital of Thessaloniki, Outpatient Clinic for Pulmonary Hypertension Time frame October 2014 – February 2017
8
Materials and methods – patient population
>18 years old Age Both male and female Sex Precapillary PH classified as Group 1 and 4 Diagnosis Treatment naive Incident patients After initiation of PAH targeted therapy (regular FU or clinical deterioration) depending on usual care Available FU RHCs

Materials and methods - procedures
mRAP CI SVO2 mPAP PAWP PVR CI: thermodilution

Results I – patient population
Patients that underwent RHC N=115 No PH N=12 Incident cases of PH N=44 Group I N=13 Patients on treatment N=59 Group IV N=4 No repeat RHC N=27 IPAH 3 CHD-corrected 1 CTD 7 PoPAH 2 Persistent 1 Inoperable 3 Group 1 N=13 Group 4 N=4

This is real life data showing that advance PH treatment led to
Conclusion This is real life data showing that advance PH treatment led to Improvement of mPAP PVR No change in prognostic indexes in PAH In patients with precapillary pulmonary hypertension
16
Limitations Study design Single center, one arm
Small patient population Variety in treatment options
