Abstract:
OBJECTIVES: It is well known that many chronic alcoholics manifest diastolic dysfunction of left ven tricle in its early stage. But the effects of chronic alcohol drinking on right ventricular function are not well understood. Thus left ventricular filling impair ment and its effects to right ventricular diastolic function were evaluated in young chronic alcoholics. METHODS: For the evaluation of left and right ventricular diastolic function in chronic alcoholics, 30 young chronic alcoholics and 28 control subjects were studied by pulsed Doppler echocardiography at the left and right ventricular inflow. Peak E velocity, peak A velocity, E/A velocity ratio, acceleration time and deceleration time were measured as diastolic filling parameters. RESULTS: 1) In the chronic alcoholics, the interventricular septum and posterior wall were thicker and left ventricular muscle mass was significantly increased than that in controls. 2) Among 30 cases of chronic alcoholics, 8 cases(26.7%) showed that the E/A ratio of the left ventricle was less than 1.0 and the deceleration time of the left ventricle was more than 240msec, where as 12 cases(40.0%) showed that the E/A ratio of the left ventricle was less than 1.0. 3) Among 30 cases of chronic alcoholics, 8 cases (26.7%) showed that the E/A ratio of the right ventri cle was less than 1.0 and the deceleration time of the right ventricle was more than 232msec, whereas 14 cases(46.7%) showed that the E/A ratio of the right ventricle was less than 1.0. 4) The RV E/A ratio was significantly correlated with the LV E/A ratio(r=0.697, p<0.001). 5) Blood pressure, ejection fraction, left ventricular mass, E/A ratio and deceleration time of both ventricles were not significantly different in comparison with the daily average amount, duration of ingestion, and total lifetime dose of alcohol. CONCLUSION: In all chronic alcoholics less than 50 years of age, the left ventricular systolic function was normal. But Doppler echocardiography showed that diastolic dysfunction of the left and right ventricles was present in 8 cases of 30 chronic alcoholics. Right ventricular diastolic dysfunction was closely related with left ventricular diastolic dysfunction. In conclu sion, diastolic dysfunction of both ventricle in chronic alcoholics may be the earliest functional sign of preclinical alcoholic cardiomyopathy.
