  • Title: [Possible relationship between acute viral myocarditis and dilated cardiomyopathy].
    Author: Jiang J.
    Journal: Zhonghua Xin Xue Guan Bing Za Zhi; 1992 Feb; 20(1):4-6, 69. PubMed ID: 1327706.
    Abstract:
    To explore the possible relationship between acute viral myocarditis and dilated cardiomyopathy (DCM), 35 acute diffuse viral myocarditis (ADVM) patients with cardiac enlargement were studied for 6 years on average. The results showed that: (1) In 22 ADVM patients, the dilated hearts had returned to normal on X-ray films. The other 13 cases still had cardiac enlargement complicated with various degrees of cardiac insufficiency (NYHA II/III) and ECG abnormalities. The manifestation of these 13 patients resembled those seen in the early stage of DCM. (2) Serum neutralizing antibody titres of Coxsackie B virus (CBV) in 35 ADVM patients after 6 years observation on average were significantly higher than those cases with cardiac enlargement induced by other causes (P less than 0.01). High neutralizing antibody titres (greater than or equal to 320) to CBV were more common among the patients with ADVM 65.7% vs 25.7% (P less than 0.05). The results indicate that some cases of ADVM might develop into DCM.
