- W2955463148 abstract "We evaluated long-term prognosis according to improvement of pulmonary hypertension (PH) and left ventricular ejection fraction (LVEF) in patients with heart failure with reduced ejection fraction (HFrEF) and PH.We included all consecutive patients with HFrEF and PH who had a baseline and follow-up echocardiographic examinations from September 2011 to March 2017. PH was defined as maximal velocity of tricuspid regurgitation (TR Vmax) over 3.0 m/s, and LVEF improvement was defined as LVEF change ≥ 15% from the baseline echocardiography. Primary outcome was 5-year major adverse cardio-cerebrovascular events (MACCE).We analyzed 271 patients. Mean LVEF was 28±8% and TR Vmax was 3.4±0.4 m/s. On follow-up, 183 (68%) showed improvement of LVEF, and 165 (61%) demonstrated improvement of PH. We classified patients into 4 groups according to improvement of PH and LVEF; group 1 (both improvement, 134 patients), group 2 (PH improvement only, 31 patients), group 3 (LVEF improvement only, 49 patients) and group 4 (no improvement, 57 patients). Group 4 had older age, higher incidence of myocardial infarction and aggravation of pre-existing HF. During the follow-up (31±20 months), 27% died and 40.8% experienced MACCE. Group 4 had the worst survival (HR=4.332, 95% CI=2.396-7.833, p<0.001), and group 3 had increased MACCE rate (HR=2.030, 95% CI=1.060-3.888, p=0.033) compared with group 1. Group 2 had similar long-term clinical events (HR=1.085, 95% CI=0.458-2.571, p=0.853) to group 1.In patients with HFrEF and PH, persistence of PH and no LVEF improvement was associated with the worst long-term outcome." @default.
