澳门地区307例心房颤动的病因分析

目的 探讨澳门地区心房颤动的病因特征。方法 对1993～1998年本院内科住院病人中4518例发生心房颤动307例患者的病因进行分析。结果 心房颤动总发生率为6.78％,风湿性心瓣膜病心房颤动发生率为29.65％,甲状腺机能亢进症、冠心病和高血压性心脏病分别为7.06％、6.23％和6.05％。在房颤瓣膜性心脏病占房颤病因构成比16.61％;非瓣膜性心脏病占79.48％。结论 本组病人房颤发生率依次为风湿性心脏病、甲状腺机能亢进症、冠心病和高血压性心脏病、肺源性心脏病、心肌病、先天性心脏病,瓣膜性心脏病占房颤病因构成比少数,非瓣膜性心脏病占大多数;房颤并非冠心病的常见临床表现。

The analysis of causes in 307 cases on atrial fibrillation

Objective To investigate the etiology feature of atrial fibrillation in Macao. Methods Etiology in 307 cases of atrial fibrillation was analyzed in 4 518 cases of our hospital department of Internal Medicine from 1993 to 1998. Results The total incidence of atrial fibrillation was 6.78%, the incidence of atrial fibrillation on rheumatic heart disease was 29.65%, the incidence of atrial fibrillation were 7.06%, 6.23% and 6.05% respectively in hyperthyroidism, coronary artery disease and hypertensive heart disease. The incidence of atrial fibrillation was much significant difference among rheumatic heart disease, hyperthyroidism, coronary artery disease, hypertensive heart disease, cor pulmonal, cardiomyopathy and congenital heart disease (P<0.005); there was much significant difference among rheumatic heart disease, groups A including hyperthyroidism, coronary artery disease, hypertensive heart disease and groups B including cardiomyopathy, cor pulmonale, congenital heart disease(P<0.005); there was significantly difference between groups A and groups B (P<0.025); groups A was higher than groups B; there was no difference among hyperthyroidism, coronary artery disease and hypertensive heart disease ( P > 0. 5); there was no difference among cor-diomyopathy, cor pulmonale and congenital heart disease (P > 0. 25). The incidence of atrial fibrillation in rheumatic heart disease was higher than other disease. The proportions of atrial fibrillation were 16.61% and 79.48% respectively in valvular heart disease and nonvalvular heart disease. Conclusion Atrial fibrillation were incidenced in proper order on rheumatic heart disease, hyperthyroidism, coronary artery disease, hypertensive heart disease, cor pulmonale, cardiomyopathy and congenital heart disease, the proportions of atrial fibrillation were minority and majority respectively in valvular heart disease and nonvalvular heart disease; atrial fibrillation was not common clinical manifestation of coronary heart disease.
