Abstract:
Objective To investigate the application data of 6-minute walk test to evaluate the surgical effect of congenital heart disease with pulmonary hypertension.Methods 83 cases of congenital heart disease with pulmonary hypertension were selected and divided into mild(28 patients) ,moderate(30 patients) and severe(25 patients)three groups according to the ultrasound preoperative pulmonary artery systolic pressure estimation (SPAP), all patients underwent surgery correction of heart defects, and before and after surgery the patients were detected SPAP and 6MWT,6MWT observed for evaluating the effect of surgery. Results After surgery,the SPAP of, mild, moderate and severe group were ( 28.7 ± 5. 6) mm Hg, ( 28.7 ± 5.6 ) mm Hg, ( 28.7 ± 5.6 )mm Hg, significantly decreased, 6 MWT were (436. 5 ± 37. 0) m, ( 411.0 ± 39. 8 ) m, ( 338.7 ± 32. 4 ) m, significantly increased, more significant changes in moderate group; The mechanical ventilation and ICU stay of severe group were ( 12. 6 ± 3.2) h, ( 5.5 ± 1.0) d, significandy longer than the mild and moderate groups ( t = 11. 770,6. 118,18. 721,9. 970, all P ＜ 0. 05 ). Conclusion 6-minute walk test to evaluate the surgical effect of congenital heart disease with pulmonary hypertension had clinical significance,and in moderate to severe pulmonary hypertension in patients with clinical assessment more meaningful,and it was worthy of attention.
