The main objective of this study is to investigate changes of features of rheumatic fever (RF) in recent 10?years. A total of 315 patients with RF during 1985-995 (group 1) and 1997-007(group 2) were selected. Their manifestations were compared. Results show that the female/male ratio was 2.0. Group 2 had higher rate of low-grade fever and carditis, and lower rate of heart failure, lower positive rate of C-reactive protein and antistreptolycin o than group 1. In group 2, 61.4% patients fulfilled the updated Jones criteria, however, 76.2% fulfilled 2002-003 WHO criteria. Diagnosing rheumatic carditis, sensibility and specificity of lymphocyte procoagulant activity (PCA) were 79.1 and 71.4%, respectively, and those of antibody to streptococcal polysaccharide (ASP) were 70.3 and 70%, respectively. Follow-up data of 35 cases were available. Recurrent rate of RF was 62.8%. Only 1/3 cases received regular secondary prevention. In conclusion, mild carditis was increasing. PCA and ASP were valuable tests for diagnosing rheumatic carditis. Atypical cases and secondary prevention need more attention.
