Abstract:
Objective To analysis of risk factors for left atrial thrombosis in patients with rheumatic mitral stenosis.Methods From January 2001 to December 2008, 2277 patients with rheumatic mitral stenosis underwent operations in our hospital. There were 737 males and 1540 female, the age ranged from 19 to 84 years [average (50.9 ±10.2) years]. Left atrial thrombosis group (554 cases) and no thrombosis group (1723 cases) were divided, retrospectively collected data were analyzed with univariate and multivariate Logistic regression. Results 12 bvariables, including age, mitral valve orifice area, left atrial diameter, left ventricular diastole diameter, CRP, gender , degree of mitral stenosis, or regurgitation, degree of bicuspid regurgitation, degree of pulmonary hypertension, atrial fibrillation and heart function had statistic difference between two groups. With multivariate Logistic regression for these 12 factors, age, mitral valve orifice area, left atrial diameter, degree of mitral regurgitation and atrial fibrillation were found to be the affecting factors for left atrial thrombosis in patients with rheumatic mitral stenosis. Conclusion For patients with rheumatic mitral stenosis, age, mitral valve orifice area, left atrial diameter and atrial fibrillation are the risk factors for left atrial thrombosis. Mitral regurgitation is a protective factor for left atrial thrombosis.
