Dogs with chronic biliary cirrhosis and portal hypertension commonly develop plasma volume expansion, urinary sodium retention, ascites, and perturbed systemic hemodynamics, i. e., a rise in cardiac output and a fall in peripheral vascular resistance. Our laboratory has previously demonstrated that creating a side-side portacaval anastomosis in such animals, and so venting hepatoportal pressure, will prevent sodium retention and ascites formation and will maintain the animals euvolemic. In the present study, in four cirrhotic dogs with such an anastomosis, observations made at 12 weeks postbiliary duct ligation, and in the presence of grossly disturbed liver function and morphology, failed to demonstrate any change from control conditions in arterial blood pressure, cardiac output, or peripheral vascular resistance. We conclude that venting hepatoportal pressure in cirrhotic dogs with markedly disturbed liver function prevents the advent of a hyperdynamic circulation, possibly by preventing volume expansion.

Background. The direction of changes in hemodynamic parameters during the tilt test (TT) nin individuals with history of vasovagal syncope (VVS) is a subject of discussion. Objective: to study changes of volume-impedance hemodynamic indicators in the process of tilt test in somatically healthy young men with history of VVS. Materials and methods. A total of 102 men aged 18–30 years were divided into 4 groups, taking into account the specific features of fainting history and response to TT. Persons of group 1 (n=14) had history of VVS and positive response to TT (syncope). Subjects of group 2 (n=14) had history of VVS and a pattern of postural tachycardia without fainting during TT. Persons of group 3 (n=42) had history of VVS and negative response to TT. Subjects of group 4 (n=32) had no history of VVS and negative response to TT. During TT, we studied dynamics of some indicators, including cardiac output (CO) and total peripheral vascular resistance (TPVR). Results. In individuals of all groups in the initial horizontal phase of TT values of CO and TPVR corresponded to the norm. Subjects of group 1 had significantly lower CO compared with subjects of groups 2, 3, 4 (p<0.05, p<0.01, p<0.05, respectively). Values of TPVR in subjects of group 1 were significantly higher than in subjects of groups 2, 3, 4 (p<0.05; p<0.05; p<0.05, respectively). In response to orthostasis CO values increased in groups 1, 2, 4 (by 18%, 10%, 5%, respectively) and did not change in group 3; TPVR values decreased in groups 1, 2 (by 8%, 0.5%, respectively), and increased in groups 3, 4 (by 8%, 4% respectively). In the final horizontal phase of TT, CO values in group 1 were significantly lower than in groups 3, 4 (p<0.05), while TPVR values did not significantly differ between all groups (p>0.05). Conclusions. In tilt-positive and tilt-negative subjects with history of VVS, standardized postural stress leads to unidirectional changes in cardiac output, but to multidirectional changes in total peripheral vascular resistance.

Dynamic Series

By the method of fractional trends, when analyzing the dynamic series of blood pressure (АД), an antagonism between the cardiac output block (CB) and the peripheral vascular resistance block (СПС) was revealed in the patient, after 12 weeks of nicergoline therapy, at the 1-3 hierarchical level of systemic regulation. At the subordinate 4-6 levels of the hierarchy, the phenomenon of antagonism was also revealed. When regulating systolic (САД) and diastolic (ДАД) blood pressure, this method revealed that nicergoline has a greater effect on the regulation of ДАД.

Circulation Types

Aim. To develop a method for determination of the differentiated types of hemodynamics based on the data analysis of integral circulation indicators. Methods. The method for determination of the differentiated hemodynamics types was developed based on the data analysis of integral circulation indicators - cardiac output, heart rate, total peripheral vascular resistance and modulus of volume elasticity. The types of hemodynamics - hyperkinetic, eukinetic, hypokinetic - were determined by cardiac output. Tachy-, normo- and bradisistolic subtypes were determined by the heart rate, subtypes with a predominance of vascular resistance and arterial stiffness were determined by the modulus of volume elasticity and total peripheral vascular resistance ratio. Four groups of patients were examined. The first group included 63 patients with I-III degree of arterial hypertension aged 18 to 77 years, mean age 48.9±12.38 (M±σ). The second group - 82 patients with primary hypothyroidism and I-III degree of arterial hypertension aged of 41 to 75 years, 59.8±7.9 years (M±σ). The third group - 33 patients with rheumatoid arthritis and I-III degree of arterial hypertension aged 17 to 67 years, 47.2±8.12 years (M±σ). The control group included 32 healthy volunteers aged 21 to 37 years, 24.7±5.34 years (M±σ). Results. Eukinetic and hyperkinetic circulation types with predominance of peripheral vascular resistance were mostly identified in healthy volunteers. Eukinetic type of hemodynamic with predominance of peripheral vascular resistance is typical for patients with hypothyroidism and arterial hypertension, and for patients with rheumatoid arthritis and arterial hypertension hyperkinetic and eukinetic types with predominance of the arterial system rigidity are characteristic. Eukinetic and hypokinetic circulation types with predominance of both peripheral resistance and arterial stiffness are mostly present in essential hypertension. Conclusion. Developed method of distinguishing the differentiated types of hemodynamics allows determining the hemodynamic heterogeneity in both healthy people and patients with hypertension.
