Hemodynamic Change in Liver Cirrhosis

The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects

The Clinical Evaluation of Antihypertensive Effect of Minizide(R)

Although a variety of agents have been introduced for the treatment of hypertension, the ideal drug has not yet been discovered. However, among the agents available, prazosin hydrochloride (Minipress(R)) appears to be accepted by the majority of physicians as it lowers blood pressure effectively with relatively low incidence of side effects. It has been considered that the hypotensive effect of prazosin is a result of peripheral vasodilation due to direct relaxation of vascular smooth muscle and blockade of alpha-adrenergic receptors in the arteriolar smooth muscle. Following the development of prazosin. many trials have been designed to potentiate its hypotensive effect by the combination with other agent, especially thiazide or beta blocker. Minizide(R), a preparation that thiazide is added to prazosin, is an example. The antihypertensive effect of Minizide(R) was evaluated in 30 hypertensive subjecs. The results were as follows; 1. The systolic and diastolic blood pressure were effectively lowered in both supine and standing position with the overall response rate of 86.7% as judged to be responsive in one that lost systolic pressure more than 15 mmHg and distolic pressure 10 mmhg. Among 30 cases 18 cases could be maintained with their diastolic pressure below 90 mmHg and 24 cases with their diastolic pressure below 100 mmHg by the end of 8th week of treatment with the daily dose of minizide(R) from a half tablet to two tablets. 2. During the period of 8 weeks, troublesome postural hypotension was not observed in any case. The pulse rate was not accelerated significantly by Minizide(R) treatment. 3. Minimal side effects were recorded in 5 cases; two of mild nausea, one of slight dizziness, one of minimal gastrointestinal irritation symptom and one of mild glucosuria. neither of them hindered the authors from finding the study.
