Background. The aim of the study was to compare the acute training effect on the cardiovascular changes under influence of different kinds of health enhancing exercising.Methods. Ten healthy males carried out two health promotion sessions by applying strength type exercising or Nordic-walk. Cardiovascular functional state was assessed before the training session and 30 minutes after the health promotion session by continuous 12-lead ECG recording while performing a Roufier Test (30 squats per 45 s) and by measuring arterial blood pressure.Results. A significant increase in the heart rate at rest was registered after the training session both after the gym training and after Nordic-walking session and reduced diastolic blood pressure values were recorded at rest and after the exercise stress test. If prior to the exercise sessions transient ischemic episode in some subjects was registered, after the training sessions the ischemic episodes were less expressed.Conclusion. Comparing the Nordic walking exercise effects with the effects of strength training exercising during the training session, less increased heart rate and systolic blood pressure were observed; a significantly higher decrease in the diastolic blood pressure, and a significantly lower degree on the short-term effects of functional ischemic myocardium were recorded.Keywords: Nordic walking, strength exercise, cardiovascular system.

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.

Glucagon Like Peptide 1

This study was designed to determine the effects of glucagon-like peptides (GLP) on arterial blood pressure and heart rate. Although glucagon caused a minimal effect and GLP-1-(1-37) produced a moderate increase of both systolic and diastolic blood pressure, GLP-1-(7-36) amide induced the greatest increases in both parameters. Systolic and diastolic blood pressure and heart rate values increased when doses of the peptides were increased. By contrast, GLP-2 did not modify either arterial blood pressure or heart rate values. To determine whether the effects of GLP-1-(7-36) amide were mediated through catecholamines, the rats were pretreated with reserpine, propranolol, or phentolamine before administration of the peptide. In these three experimental groups, GLP-1-(7-36) amide increases mean arterial blood pressure and heart rate to the same level or even greater than that observed in nonpretreated rats. These findings indicate that GLP-1-(7-36) amide significantly increases arterial blood pressure and heart rate and that these effects are not mediated through catecholamines.

Reliable Assessment

1. We have assessed the day-to-day reproducibility of intra-arterial blood pressure by monitoring 17 freely ambulant hypertensive patients for a period of 48 h. Eight had no change of therapeutic regimen throughout and nine took a single dose of a hypotensive agent before retiring on the second night. 2. Records were analysed to provide hourly mean values of heart rate, systolic and diastolic blood pressure. No significant differences between first and second day recordings were found except after the intervention in the second group. 3. Allowing subjects to follow their normal daily routine produces inevitable variation in their pattern of physical and other activity. However, by the use of these methods of recording and analysis, with pooled measurements from a small group of subjects, reproducibility is sufficiently good to permit the reliable assessment of therapeutic interventions.

The Impact

Esmolol, a recently developed ultra-short acting β-adrenoceptor blocking agent, was evaluated in 12 conscious chronically instrumented dogs with intact autonomic reflexes. The significance of its β1-adrenoceptor selectivity was examined at various cardiovascular activation levels established by either incremental isoprenaline infusion or graded treadmill exercise. The observed parameters were heart rate, systolic and diastolic arterial blood pressure, left ventricular dp/dtmax, and left ventricular end-diastolic pressure. Intravenous infusion of esmolol (25 and 250 μg∙kg−1∙min−1) led to a dose-dependent reduction of the isoprenaline-induced increase in positive dp/dtmax. The concomitant increase in heart rate was suppressed to a lesser extent. Characteristically of a β1-selective agent, esmolol had only a slight effect on the isoprenaline-induced reduction in diastolic blood pressure. The impact of esmolol on exercise-induced hemodynamic activation was much smaller. Exercise-induced increase in positive dp/dtmax was more sensitive to β-adrenoceptor blockade than the concomitant increase in heart rate. Diastolic blood pressure was not influenced significantly. β-Adrenoceptor blockade was virtually reversed within 20 min of discontinuation of esmolol infusion.Key words: esmolol, β1-adrenoceptor selectivity, dogs, treadmill exercise, isoprenaline stimulation.

AIM: This study aimed to compare the effects of dexmedetomidine and propofol in controlling the hemodynamic response following intubation of patients’ candidate intubation in the emergency department METHODS: A total of 114 patients were randomly assigned to one of 2 groups to receive one of the following treatments: dexmedetomidine 0.4 µg/kg (Group D, n = 57) and propofol 1–1.5 mg/kg/h (Group P, n = 57). Hemodynamic data such as the systolic blood pressure, diastolic blood pressure, arterial oxygen saturation and heart rate (HR) were recorded from the entrance to operation room to 5, 10 and 15 min after tracheal intubation RESULTS: Compared with group D, group P exhibited increases in mean arterial blood pressure (MAP), and systolic blood pressure significantly at all times and immediately after the endotracheal intubation. Moreover, the mean diastolic blood pressure changes due to tracheal intubation in group P were significantly more than group D immediately after the intubation. Furthermore, the mean heart rate changes immediately and 5 min after tracheal intubation was significantly higher in group P CONCLUSION: Our data suggest that the benefits of dexmedetomidine more than propofol in hemodynamic stability because propofol was associated with more variability in systolic/diastolic blood pressure, HR and MAP after endotracheal intubation.

Background: Individuals post-stroke commonly presents functional and cardiorespiratory deficits besides a physical inactivity lifestyle in the chronic phase of disease. Considering this, there is a hypothesis that hemodynamic responses could be affected by motor, cognitive and cardiorespiratory deficits during the aerobic exercise. In order to identify functional conditions that can influence the aerobic performance of these individuals, correlations between functional variables and hemodynamic responses during and after the aerobic exercise were studied. As a secondary purpose, the ability of return to hemodynamic resting state were also analyzed. Methods: In this experimental study, after being evaluated about their motor and cognitive function, balance and prognosis, forty participants underwent a 30-minute aerobic exercise session on a treadmill. Training heart rate, arterial blood pressure, oxygen pulse saturation, heart rate, and respiratory rate were measured before begin the exercise session, every five minutes during the exercise and five minutes after it.  Results: Cardiorespiratory parameters within normality limits in all phases of the exercise and the capacity of returning to the resting state were observed. Moderate inverse correlations were found between Berg Scale and oxygen pulse saturation (r=-0.401, p=0.01), between MMSE and diastolic blood pressure (r=-0.406, p=0.009), age and diastolic blood pressure (r=-0.435, p=0.005) and between injury time and RR (r=-0.454, p=0.003). Relationship between the lesion side and the 20 minute phase of aerobic exercise was also observed (p=0.042).   Conclusion: Post- stroke individuals present moderate correlation between hemodynamic and respiratory responses during aerobic exercise and balance, muscle strength, injury time, age and side of lesion. They also have the capacity to return to their cardiorespiratory and cardiovascular resting state right after the activity besides their cardiorespiratory deficits.

AbstractThis study aimed to assess whether obesity and/or maximal exercise can change 24 h cardiac autonomic modulation and blood pressure in young men. Thirty-nine men (n: 20; 21.9±1.8 kg·m−2, and n: 19; 32.9±2.4 kg·m−2) were randomly assigned to perform a control (non-exercise) and an experimental day exercise (after maximal incremental test). Cardiac autonomic modulation was evaluated through frequency domain heart rate variability (HRV). Obesity did not impair the ambulatory HRV (p>0.05), however higher diastolic blood pressure during asleep time (p=0.02; group main effect) was observed. The 24 h and awake heart rate was higher on the experimental day (p<0.05; day main effect), regardless of obesity. Hypotension on the experimental day, compared to control day, was observed (p<0.05). Obesity indicators were significantly correlated with heart rate during asleep time (Rho=0.34 to 0.36) and with ambulatory blood pressure(r/Rho=0.32 to 0.53). Furthermore, the HRV threshold workload was significantly correlated with ambulatory heart rate (r/Rho=− 0.38 to−0.52). Finally, ambulatory HRV in obese young men was preserved; however, diastolic blood pressure was increased during asleep time. Maximal exercise caused heart rate increase and 24h hypotension, with decreased cardiac autonomic modulation in the first hour, regardless of obesity.

1. Dose-response curves for heart rate, cardiac output, arterial blood pressure and pulmonary artery pressure were obtained in 16 male patients after intravenous administration of three increasing doses of pindolol, propranolol or placebo. All patients had an uncomplicated acute myocardial infarction 6–8 months earlier. 2. The dose-response curves were obtained at rest and during repeated bouts of supine bicycle exercise. The cumulative dose amounted to 0.024 mg/kg body weight for pindolol and to 0.192 mg/kg body weight for propranolol. 3. At rest propranolol significantly reduced heart rate and cardiac output by 12% and 15% respectively. Arterial mean blood pressure was reduced by 9.2 mmHg. Mean pulmonary artery pressure increased significantly by 2 mmHg. Statistically significant changes in these variables were not seen after pindolol or placebo. 4. During exercise pindolol and propranolol both reduced cardiac output, heart rate and arterial blood pressure to the same extent. After propranolol mean pulmonary artery pressure was increased significantly by 3.6 mmHg. Pindolol and placebo did not change pulmonary artery pressure significantly. 5. The study suggests that pindolol may offer haemodynamic advantages over β-receptor-blocking agents without intrinsic sympathomimetic activity during low activity of the sympathetic nervous system, and may be preferable in situations where the β-receptor-blocking effect is required only during physical or psychic stress.
