Objectives: It is well known that many chronic alcoholics manifest diastolic dysfunction of left ventricle in its early stage. But the effects of chronic alcohol drinking on right ventricular function are not well understood. Thus left ventricular filling impairment 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 ventricle 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 HV 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 conclusion, diastolic dysfunction of both ventricle in chronic alcoholics may be the earliest functional sign of preclinical alcoholic cardiomyopathy.

부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.
