Orthostatic Test

Aim: to identify the influence of body length on the indicators of vegetative-vascular regulation of student-athletes.  Material and methods. The study involved 42 second-year students who play sports at the amateur level (qualification level - 2-3 sports degree). The following research methods were used in the work: method of analysis of literary sources; method of determining body length; orthostatic test method; method of determining stroke volume and minute blood volume. Results. It was found that the increase in systolic blood pressure during the transition from horizontal to vertical position in students whose body length is above 190, significantly higher than in students whose body length does not exceed 175 cm (p <0.01) diastolic blood pressure, then in students whose body length is above 190 cm, this figure is significantly higher (p <0.01) both horizontally and vertically. The stroke volume of tall (more than 190 cm body length) students in the standing position is significantly less than that of students with a body length of 150-175 cm. There is a significant effect of body length on systolic blood pressure in the standing position, diastolic blood pressure in the supine and standing positions, heart rate in the supine and standing positions, stroke volume in the standing position, minute blood volume in the supine position and standing (p <0,001). The effect of body length on the orthostatic test was also significant for the following data: systolic blood pressure in the vertical position, diastolic blood pressure in the vertical position; change in diastolic blood pressure when changing body position from horizontal to vertical; heart rate in vertical and horizontal positions; change in heart rate during the transition from horizontal to vertical position; stroke volume of blood in the vertical position; change in stroke volume of blood during the transition from horizontal to vertical position; all indicators of minute blood volume. Conclusions. The state of the cardiovascular system of student-athletes is characterized by high fitness. It was found that students with a body length of more than 190 cm have difficulty with vegetative-vascular regulation.

Vascular Regulation

Purpose: to reveal the features of the indicators of the orthostatic test in students with different body lengths and different sport´s specializations, studying in the specialty "Physical education and sports". Material and methods. The study involved 42 students who play sports at the amateur level. The following research methods were used in the work: method of analysis of literary sources; method of determining body length; orthostatic test method; method of determining stroke volume and minute blood volume. Results. The influence of both factors (body length and sport) on the orthostatic test was significant for the following data: systolic blood pressure in the vertical position, diastolic blood pressure in the vertical position; change in diastolic blood pressure when changing body position from horizontal to vertical; Heart rate in vertical and horizontal positions; change in heart rate during the transition from horizontal to vertical position; stroke volume of blood in the vertical position; change in the stroke volume of blood during the transition from horizontal to vertical position; all indicators of minute volume of a blood-groove (p <0,005; p <0,01; p <0,001). The more significant influence of judo and football classes in comparison with running short and medium distances on the indicators of vegetative-vascular regulation was determined: the best indicators - in judo, the next place - in football, then - athletes. It was found that students with a body length of more than 190 cm have difficulty with vegetative-vascular regulation. Conclusions. To improve the adaptive capacity of vascular regulation to change the position of the body from horizontal to vertical in tall athletes is effective to use any exercise, but the most effective exercises that activate aerobic and anaerobic glycolytic energy systems. Also useful are exercises that require frequent transitions from lying down (sitting) to standing position, as well as changes in the direction of movement.

This study was designed to determine if visualization of anger- and fear-provoking scenes produced differential physiological patterns similar to those produced by in vivo manipulations. Normotensive college students were selected on the basis of their responses to newly developed Anger and Fear/Anxiety questionnaires and for their ability to construct arousing scenes during a screening interview. In a 2 × 2 design (intensity × emotion), four scenes (high and low anger, high and low fear) were constructed individually for each of 16 subjects to imagine. Diastolic blood pressure, systolic blood pressure, and heart rate were monitored during visualization of each scene. Change in diastolic blood pressure was significantly greater for high anger than for high fear as predicted. Analysis of change in heart rate and systolic blood pressure showed significant effects for intensity only. These results provide further support for the concept of physiological differentiation in human emotion and suggest the utility of imagery for systematic study of human emotional responding.

Introduction: Acute coronary syndrome remains as one of the most important causes for morbidity and mortality in developed countries. Therefore, evidence-based management strategy is required to offset the loss of health during an acute coronary syndrome. An effective approach includes both medical and surgical methods. This study was conducted to evaluate the medical method of management. Objective: To study blood pressure and heart rate variability after administration of Ivabradine or metoprolol in cases with acute coronary syndrome. Materials and methods: The study was a Prospective single center observational study conducted in patients attending Cardiology Intensive Care Unit in Nayyar Heart and Superspecialty Hospital, a tertiary care centre located in an urban area. All patients with Acute coronary syndrome admitted to the emergency or cardiac care unit were analysed with ECG as a preliminary diagnostic test and confirmed with troponin markers. They were either given Ivabradine or Metoprolol. Baseline evaluation and follow up was done and necessary data was collected and analysed.   Results: 100 patients were included in the study out of which 50 were given Metoprolol (Group A) and 50 were given Ivabradine (Group B). Themean age of studied cases was found to be 66.54 years in group A and 68.69 years in group B. It was observed that there was a fall in heart rate by 26.8 beats per minute with beta blocker and 24.4 beats per minute with Ivabradine. In case of blood pressure measurement, in patients with beta blocker administration, there was a fall of 25 mm Hg in systolic blood pressure and 17 mm Hg in diastolic blood pressure However, with Ivabradine there was only a fall of 8mm Hg in systolic Blood pressure and 6 mm Hg in diastolic blood pressure. Conclusion: Although Metoprolol is the drug of choice to decrease heart rate and blood pressure in acute coronary syndrome, Ivabradine is being increasingly used in cases where beta blockers are contraindicated as it has similar efficacy in lowering heart rate without compromising contractility of cardiac muscle, thereby maintaining LVEF and blood pressure. Keywords: Acute coronary syndrome, Beta Blockers, Metoprolol, Ivabradine.

Effects Of Aging

1. We studied the effects of aging on the variability of blood pressure in mild to moderate essential hypertensive subjects. 2. Cardiac index was greater and total peripheral resistance index was less in patients under 40 years (by an average of 1.06 litres min−1 m−2 and 9.23 mmHg 1−1 min−1 m−2) than in those over 40 respectively (P < 0.001 for each). 3. Pulse pressure/stroke volume was less by an average of 0.345 mmHg/ml in patients under 40 years than that in those over 40 (P < 0.001). Pulse pressure/stroke volume was correlated with age (r = 0.621), average systolic blood pressure (r = 0.623) and inversely with baroreflex sensitivity (r = −0.494). 4. Baroreflex sensitivity was less by an average of 3.1 ms/mmHg in patients over 30 years than in those under 30 (P < 0.025). Baroreflex sensitivity was inversely correlated with age (r = −0.617) and average systolic blood pressure (r = −0.589). 5. Beat by beat variability of systolic blood pressure was correlated with age (r = 0.460), particularly when the data of those in their twenties were excluded (r = 0.618), and significantly with pulse pressure/stroke volume (r = 0.650), average systolic blood pressure (r = 0.618) and inversely with baroreflex sensitivity (r = −0.477). These relationships were not observed for diastolic blood pressure. 6. Maximum difference in systolic blood pressure in a day was correlated with pulse pressure/stroke volume (r = 0.482) and average systolic blood pressure (r = 0.648) but not with baroreflex sensitivity. These relationships were not observed for diastolic blood pressure. 7. Variability of systolic blood pressure in patients over 30 years gradually increased with age. In contrast, those of systolic and diastolic blood pressures in subjects in their twenties were relatively large. This might be related to factors other than aging, presumably those which underlie the hyperdynamic circulatory state.

Background: The ideal method to prevent hypotension due to intravenous propofol for induction of anesthesia is still debatable. The aim of the study was to compare the hemodynamic response of ephedrine and volume loading with ringer lactate in preventing the hypotension caused by propofol as inducing agent in patients scheduled for elective surgeries requiring general anesthesia with endotracheal intubation.Methods: This was prospective randomized study conducted in 40 patients of ASA physical status I, aged 20-50 years, scheduled for elective surgeries requiring general anesthesia with endotracheal intubation. Group I received intravenous ephedrine sulphate (70 mcg/kg) just before induction of anaesthesia, and patients assigned to Group II received preloading with Ringer's lactate (12 ml/kg) over the 10-15 minutes before the administration of propofol. The variables compared were heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure following induction of anesthesia till 10 minutes after intubation of trachea.Results: We found that there were increase in systolic blood pressure, diastolic blood pressure and mean arterial pressure after induction in both the groups but the difference between the groups was not significant. The increase in heart rate was found to be significantly higher in ephedrine group in comparison to volume loading group.Conclusion: Our study showed that both the methods used were equally effective in preventing hypotension induced by propofol in the adult ASA physical status I patients requiring general anesthesia with endotracheal intubation. However, the heart rate was significantly higher in patients receiving ephedrine in comparison to volume loading group.

Objectives The objectives were to compare two different sedative combinations, xylazine–ketamine and dexmedetomidine–ketamine, for the short electroretinography (ERG) protocol and their impact on sedative effect, reversal times and physiological variables in cats. Methods Six healthy spayed female domestic cats were sedated using one of two ketamine-containing protocols: intramuscular xylazine hydrochloride (1 mg/kg) plus ketamine hydrochloride (3 mg/kg) (XK), and dexmedetomidine hydrochloride (5 µg/kg) plus ketamine hydrochloride (3 mg/kg) (DK). A short ERG protocol was recorded from the left eye of each cat under XK and DK sedation. Thirty minutes later, the effects were reversed with yohimbine or atipamezole for the XK and DK treatment, respectively. The cats were evaluated for time to recumbency, time to head elevation, and time to standing position after reversal treatments. Other variables recorded were: systolic blood pressure, cardiac rhythm, heart rate, pulse oximetry and respiratory rate. Recorded ERG variables included a- and b-wave amplitudes and implicit times under photopic, scotopic and scotopic mixed ERG conditions. Results Time to lateral recumbency with XK was shorter than for DK ( P <0.05). After reversal, head elevation and standing position times were significantly longer for the XK than the DK group ( P <0.05). Heart rate increased and systolic blood pressure decreased from baseline in both groups ( P <0.05), but there were no significant differences between treatment groups. The b-wave amplitude recorded in the photopic study of cats treated with XK was lower than in animals treated with DK ( P <0.05). No other significant differences in ERG variables were observed between treatment groups ( P >0.05). Conclusions and relevance The present study shows that XK and DK treatments are chemical restraint alternatives for ERG recording in cats, with significant differences only in the photopic b-wave amplitude.

Background Hypertension is a global public health issue and is closely related to chronic kidney disorder (CKD). In people with CKD, strict monitoring of blood pressure is an important part of therapy. Objective The aim of this research was to validate the iHealth Track blood pressure monitoring device for patients with CKD according to the European Society of Hypertension International Protocol 2010 (ESH-IP2). Methods In total, 33 patients who received hemodialysis in Plasencia participated in the study. There were 9 successive measurements made, which conformed to the ESH-IP2. We calculated the differences between the standard reference device (Omron M3 Intellisense) and the test device (iHealth Track) for blood pressure and heart rate values. For 99 total comparisons of paired measurements, we classified differences into various categories (≤5 mmHg, ≤10 mmHg, and ≤15 mmHg for blood pressure; ≤3, ≤5, and ≤8 beats per minute for heart rate). Results In 90 of 99 systolic blood pressure and 89 of 99 diastolic blood pressure comparisons between the devices, measurement differences were within 5 mmHg. In 81 of 99 heart rate comparisons between the devices, measurement differences were within 3 beats per minute. The mean differences between the test and reference standard measurements were 3.27 (SD 2.99) mmHg for systolic blood pressure, 3.59 (SD 4.55) mmHg for diastolic blood pressure, and 2.18 (SD 2.75) beats per minute for heart rate. We also observed that for both systolic and diastolic blood pressure, 31 of 33 participants had at least two of three comparisons between the devices with measurement differences less than 5 mmHg. For heart rate, 28 of 33 patients had at least two of three comparisons between the devices with measurement differences less than 3 beats per minute. Conclusions To our knowledge, this is the first study to show that iHealth Track meets the requirements of the ESH-IP2 in patients with CKD. Therefore, the iHealth Track is suitable for use in renal patients.

Background: During endotracheal intubation, it has been observed that there is evolvement of the responses of the circulatory in nature. These are difficult to control using the IV anesthetic drugs. Hence various agents are tried to overcome this drawback. Objective of research work was to study efficacy of oral clonidine on hemodynamic responses compared to IV fentanyl while patients undergo larngoscopy and endotracheal intubation.Methods: The patients were allocated into two groups of 30 each. i.e. 30 patients in clonidine group and 30 patients in fentanyl group. All the patients received were pre-medicated with glycoprrolate 0.2mg, ondansetron 4mg and tramadol 1mg/kg body weight. Cardiovascular parameters (heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure,) were recorded at the following intervals: pre-induction, after induction, at endotracheal intubation, one minute, three minutes and five minutes after intubation.Results: The heart rate was significantly more at various intervals in patients who belonged to fentanyl group and it was significantly lesser in clonidine group. The systolic blood pressure was significantly more at various intervals in patients who belonged to fentanyl group and it was significantly lesser in clonidine group. The diastolic blood pressure was significantly more at various intervals in patients who belonged to fentanyl group and it was significantly lesser in clonidine group. Similar was the case with mean arterial blood pressure.Conclusions: Clonidine has been found to be more effective than IV fentanyl in stabilizing the cardiovascular parameters. Not only that orally it is easier to administer and cost effective.
