Endomyocardial fibrosis in China.
OBJECTIVE
To introduce the epidemical, pathological, and clinical characteristics as well as the diagnostic and therapeutical experiences of endomyocardial fibrosis (EMF) in China.


METHODS
A CMBdisc search was done of the Chinese-language literature published from January 1983 through June 1997 about EMF and/or restrictive cardiomyopathy. A manual search was then done for other contributions, including abstracts, between January 1965 and June 1997.


RESULTS
Eighty-seven Chinese cases of EMF were collected in this paper. There were 49 men and 38 women, with a mean age of 28 +/- 13 years (range, 8 to 68 years). The distribution of the cases is mainly in the south of China. Combined right and left ventricular disease occurs in 48 percent of cases, with pure right ventricular involvement occurring in 12 percent and pure left ventricular involvement in the remaining 10 percent of patients who are examined postmortem. The diagnosis of EMF was confirmed in 21 cases at autopsy, and in 66 cases by echocardiography, angiocardiography, and/or endomyocardial biopsy which showed the characteristic changes. Clinically, right-sided disease is the commonest variety. Endocardiectomy and tricuspid (n - 7) or mitral (n - 1) valves replacement have been performed in 8 patients. There were 2 operative deaths. Six patients had a satisfactory recovery postoperatively and living well in the follow-up duration.


CONCLUSIONS
EMF has been diagnosed clinically and confirmed at necropsy in a number of cases in the south of China. The etiology, incidence and epidemiology are still unknown. The pathological and clinical features are similar to those in tropical areas, but right ventricular involvement is the commonest type in our country.
