• W2612342541 abstract "To investigate the role of pulmonary artery pressure (PAP) in predicting in-hospital death after valve replacement surgery in middle-aged and aged patients with rheumatic mitral disease.An observational study.Guangdong General Hospital, China.1639middle-aged and aged patients (mean age 57±6 years) diagnosed with rheumatic mitral disease, undergoing valve replacement surgery and receiving coronary angiography and transthoracic echocardiography before operation, were enrolled.All participants underwent valve replacement surgery and received coronary angiography before operation.In-hospital death and 1-year mortality after operation.Included patients were divided into four groups based on the preoperative PAP obtained by echocardiography: group A (PAP≤30 mm Hg); group B (>30 mm Hg<PAP≤50 mm Hg), group C (>50 mm Hg<PAP≤70 mm Hg) and group D (PAP>70 mm Hg). The relationship between PAP and in-hospital death and cumulative rate of 1-year mortality was evaluated.In-hospital mortality rate increased gradually but significantly as the PAP level increased, with 1.9% in group A (n=268), 2.3% in group B (n=771), 4.7% in group C (n=384) and 10.2% in group D (n=216) (p<0.001). Multivariate analysis showed that PAP>70 mm Hg was an independent predictor of in-hospital death (OR=2.93, 95% CI 1.61 to 5.32, p<0.001). PAP>52.5 mm Hg had a sensitivity of 60.3% and specificity of 67.7% in predicting in-hospital death (area under the curve=0.672, 95% CI 0.602 to 0.743, p<0.001). Kaplan-Meier analysis showed that patients with PAP>52.5 mm Hg had higher 1-year mortality after operation than those without (log-rank=21.51, p<0.001).PAP could serve as a predictor of postoperative in-hospital and 1-year mortality after valve replacement surgery in middle-aged and aged patients with rheumatic mitral disease." @default.
