e0553 Effect of pulmonary hypertension on the prognosis of patients with cardiac resynchronisation therapy

Introduction There was a little of information about the effect of pulmonary artery hypertension to the clinical prognosis in patients with cardiac resynchronisation therapy (CRT). We aimed to investigate the effect of pulmonary artery systolic pressure (PASP) to the response of patients with CRT. Methods 93 patients (76 male, mean ages: 61.23±15.56) with heart failure involved in our study. According to the level of preoperative PASP, they were divided into three groups (Group I: PASP ≥50 mm Hg, n=29; Group II: 30 mm Hg 0.05) and Group II (from 69 mm to 66 mm, p>0.05). LVEF increased averagely by 31–38% (p 0.05) and had increased by 17% (Group I, p Conclusions Clinical outcomes post-CRT can be predicted by elevated PASP. A preoperative PASP ≥50 mm Hg is associated with increased risks for adverse events and a higher mortality for aggravation of heart function.
