Purpose: To study a combined application of kinesis and laser therapy for correcting regional hemodynamic disorders in patients having dilatation cardiomyopathy (DCMP) with simultaneous supportive pharmaceutical therapy. Material and methods. 100 patients with a verified diagnosis of DCMP were taken into the study. All patients had a differentiated supportive pharmtherapy. In three months after selection of the supportive differentiated drug therapy, patients were divided into two groups comparable by gender, age, disease course, severity of state and ways of medicine administration. Patients from Group 1, in addition to the supporting differentiated drug therapy, were given intravenous laser blood irradiation (ILBI) and unloading physical exercises. Patients from Group 2 continued their course of differentiated drug therapy.Research techniques included: clinical and functional observations; venous-occlusive plethysmography for assessing regional hemodynamics with a generally accepted method: measurement of blood flow (Qr) and regional vascular resistance (Rr) at rest; venous tone (Vt), reserve blood flow (QH) and regional vascular resistance (RH) under the functional loading test. Results. The data obtained during dynamic observations (in 1, 3, 6, 9 and 12 months) in Group 1 demonstrated a significant increase in volumetric blood flow velocity at rest (Qr) and reserve blood flow (QH); decrease of the regional vascular resistance at rest (Rr) and under functional loading (RH) as well as the decrease of venous tone (Vt), respectively. In Group 2 (controls), there were no significant positive dynamics; moreover, regional hemodynamics significantly worsened in 9 and 12 months. Conclusion. By the findings of venous-occlusive plethysmography, regional hemodynamics significantly improved in patients with DCMP under unloading therapeutic gymnastics in combination with ILBI and correctly selected differentiated drug therapy. The developed curative technique can be used in medical practice by GPs, therapists, cardiologists for optimizing treatment of patients with DCMP.

The aim of the study: Combined use of kineso- and laser therapy to correct regional hemodynamic disorders in patients with dilated cardiomyopathy (DCMP). Material and methods: The study included 100 patients diagnosed with DCMP. The diagnosis "DCMP" was established for patients with dilatation of the heart cavity of non-coronatural origin, increased heart size (final diastolic size of the left ventricle - LV CDR > 6.0 cm). The determination of the CHF FC was made according to the Russian National Recommendations of the RSCS (2018) and OSSN on the diagnosis and treatment of CHF. All patients took differentiated medication-assisted therapy according to indications during 3 months. Patients were divided into 2 comparable groups by sex, age, disease course, severity of the condition, and specifics of medication therapy. Patients of the 1st group were treated with intravenous laser irradiation of blood (ILIB) and selection of unloading therapeutic gymnastics against the background of supporting differentiated medication therapy. Patients of the 2nd group (control) received only differentiated medication therapy. The main method of investigation was venous occlusal plethysmography to evaluate regional hemodynamics with the determination of blood flow (Qr) and regional vascular resistance (Rr) at rest, venous tone (Vt), reserve blood flow (QH) and regional vascular resistance (RH) on the background of a functional load test. РResults: The data obtained during the dynamic observation (in 1, 3, 6 and 12 months) in the main group showed a reliable increase in the volume velocity of the blood flow at rest (Qr) and the reserve blood flow (QH), a decrease in the regional vascular resistance at rest (Rr) and under functional load (RH), venous tone (Vt), respectively. In the control group there was no reliable positive dynamics, after 12 months of observation indicators of regional hemodynamics significantly deteriorated. Conclusion: In patients with DCMP, according to venous occlusal plethysmography, the use of relieving therapeutic gymnastics in combination with ILIB on the background of medication therapy has significantly improved the indices of regional hemodynamics. The developed method of non-drug therapy can be used by cardiologists, general practitioners, therapists, doctors of physical and rehabilitation medicine to optimize treatment of patients with DCMP.

Decreased vascular resistance and vasoconstrictor response during pregnancy enables an increase in cardiac output and regional blood flow to the uterine circulation. We sought to determine whether inhibition of vascular smooth muscle ATP-sensitive potassium ([Formula: see text]) channel activity during pregnancy increased systemic and/or regional vascular resistance and resistance response to ANG II. A total of 32 catheterized, awake, pregnant or nonpregnant guinea pigs were treated with either the [Formula: see text]channel inhibitor glibenclamide (3.5 mg/kg) or vehicle (DMSO) ( n = 8/group). In nonpregnant and pregnant animals, glibenclamide raised blood pressure and systemic, uterine, and coronary vascular resistance, diminishing cardiac output and organ blood flow. Glibenclamide produced a greater rise in coronary vascular resistance in the pregnant than nonpregnant groups and increased renal and cerebral vascular resistance in the pregnant animals only. ANG II infusion raised blood pressure and systemic and renal vascular resistance and lowered cardiac output and renal blood flow in vehicle-treated animals. Glibenclamide augmented ANG II-induced systemic vasoconstriction in the nonpregnant and pregnant groups and the rise in uteroplacental vascular resistance in the pregnant animals. We concluded that [Formula: see text] channel activity likely modulates systemic, uterine, and coronary vascular resistance and opposes ANG II-induced systemic vasoconstriction in nonpregnant and pregnant guinea pigs. Pregnancy augments[Formula: see text] channel activity in the uterine, coronary, renal, and cerebral vascular beds and the uteroplacental circulation during ANG II infusion. Thus increased[Formula: see text] channel activity appears to influence regional control of vascular resistance during guinea pig pregnancy but cannot account for the characteristic decrease in systemic vascular resistance and ANG II-induced systemic vasoconstrictor response.
