Obese Subjects

1. The prevalence of cardiac autonomic alterations was evaluated in 23 obese subjects with body mass index 37.2 ± 3.03 kg/m2 (mean ± sd), compared with 78 controls with body mass index 22.5 ± 2.6 kg/m2 (P < 0.001). 2. Cardiac autonomic function was assessed by four standard tests (heart rate response to deep breathing and to the Valsalva manoeuvre, systolic blood pressure fall after standing and diastolic pressure rise during handgrip) and by the cross-correlation test, a new method of computerized analysis of respiratory sinus arrhythmia based on spectral analysis of electrocardiographic and respiratory signals. 3. Considering tests indicative of parasympathetic function, only the heart rate response to the deep breathing and the cross-correlation test were significantly lower in the obese than in the control group [deep breathing = 13.95 ± 8.65 beats/min (mean ± sd) vs 24.5 ± 7.65, P < 0.001; cross-correlation 4.28 ± 0.74 units vs 5.14 ± 0.63, P < 0.001]. Deep breathing and/or cross-correlation were abnormal in 10 (43.5%) obese subjects (deep breathing: seven subjects, cross-correlation: eight subjects). No significant difference between groups was found for the response to the Valsalva manoeuvre: the Valsalva ratio was 1.69 ± 0.45 in obese subjects and 1.88 ± 0.33 in controls (P = NS). The Valsalva ratio was abnormal in three obese subjects. 4. No significant differences were found between groups for tests indicative of sympathetic function. The rise in diastolic blood pressure after handgrip was 12.6 ± 6.2 mmHg (1.67 ± 0.82 kPa) in obese subjects and 18.2 ± 4.9 mmHg (2.42 ± 0.65 kPa) in controls (P = NS), and the fall in systolic blood pressure after standing was −6.8 ± 8.6 mmHg (−0.90 ± 1.14 kPa) in obese subjects and −6.9 ± 10.4 mmHg (−0.91 ± 1.38 kPa) in controls (P = NS). The handgrip test was abnormal in four obese subjects, while no obese subject had an abnormal blood pressure response to standing. 5. Our findings suggest a high incidence of cardiac autonomic dysfunction in obese subjects. Since cardiac autonomic alterations have been shown to be involved in the mechanisms of cardiac sudden death, our data suggest a possible role of autonomic dysfunction in the increased risk for sudden death in obesity.

1. Cardiovascular responses to three different interventions, namely the Valsalva manoeuvre, deep breathing and a cold stimulus on the face, were studied in two ethnic groups (European and Bangladeshi) that have been shown to differ in the prevalence of hypertensive-vascular disease. The data obtained consisted of systolic blood pressure, diastolic blood pressure, mean blood pressure, heart rate measured by using a beat-by-beat non-invasive blood pressure monitor (the Finapres), forearm blood flow determined by venous occlusion plethysmography, and calculated forearm vascular resistance. 2. The resting haemodynamic status was similar in European and Bangladeshi subjects. However, Bangladeshi subjects showed a greater increase in heart rate, but only after 20 s into the Valsalva manoeuvre, and greater overshoots in mean blood pressure after the manoeuvre than the European subjects. Furthermore, after cold face stimulation the fall in forearm vascular resistance to baseline levels was delayed in Bangladeshi subjects relative to that in the European subjects. 3. There were no inter-group differences in the reflex bradycardia relative to mean blood pressure or in the cardiac baroreflex sensitivity estimated from systolic blood pressure and pulse interval after the Valsalva manoeuvre. In addition, values for the mean difference between maximum and minimum pulse intervals during deep breathing did not differ in Bangladeshi and European subjects. 4. These findings together suggest that, although cardiac vagal reflex responses appear similar in the two groups, sympatho-adrenal influences on the heart and vasculature may be greater in Bangladeshi subjects than in European subjects.

Introduction: The number of major abdominal surgical procedures is increasing around the world. A large number of the patients complain about postoperative pulmonary complications (PPCs) after abdominal surgery and show symptoms of breathing pattern disorder. Therefore, this study aimed to investigate the effect of deep breathing exercise on the oxygenation of patients undergoing major abdominal surgery. Methods: This single-blind randomized clinical trial was conducted on 40 patients who needed major abdominal surgery in Qom, Iran, in 2014. The participants were divided into two equal experimental (n=20) and control (n=20) groups. The cases in both groups received routine care, however, those in the experimental group exercised repeated deep breathing four times per hour for two consecutive hours after the surgery as well. The condition of the patients in both groups was similar in terms of position, mobility, and oxygen therapy. The patient’s oxygen saturation, respiratory rate (RR), heart rate, and the severity of pain in the surgery site were measured. The collected data were analyzed in SPSS software (Version. 18) using paired t-test, independent t-test, Mann-Whitney U test, Wilcoxon rank-sum test, Multiple regression analyses, Chi-square test, and Fischer’s exact test. A p-value less than 0.05 was considered statistically significant. Results: Based on the study findings, the deep breathing exercise significantly reduced the surgery site pain and mean blood pressure and increased O2 saturation in the experimental group after the intervention (P<0.05). Moreover, there was a statistically significant difference between the experimental and control groups, and a significantly higher O2 saturation was observed in the experimental group after deep breathing exercise post-operation (β=2.01, P<0.001). Conclusion: Deep breathing exercises can reduce the severity of pain in the surgery site and mean arterial blood pressure and increase O2 saturation in patients after major abdominal surgery.

Abstract Background Simple bedside cardiovascular autonomic reflex test (CARTs) are usually used to determine cardiovascular autonomic neuropathy (CAN). CAN may contribute to chronotropic incompetence (CI) which is the inability of the heart rate (HR) to rise in proportion to an increase in metabolic demand. Determination of CI is widely based on measurement of maximum HR during exercise testing. This study aimed to evaluate the role of CARTs to determine CI. Methods We included in 105 patients using a derivation and validation sampling ratio of 2:1. CARTs were performed for analyzing heart rate variation during three parasymphathetic standard tests (deep breathing, lying to standing, Valsava maneuver) and two sympathetic standard tests (systolic blood pressure from lying to standing and diastolic blood pressure during handgrip maneuver). Variables independently associated with CI in multivariable analysis in the derivation set were assigned points based on their respective odds ratios. Results CI group showed significantly lower values of among three parasympathetic standard tests (p &lt; 0.05) but not significantly among two sympathetic standars tests. Valsava maneuver (OR 0.1, p &lt; 0.001, 95%CI 0.001-0.004), deep breathing (OR 0.91, p = 0.025, 95% CI 0.836-0.988), and handgrip maneuver (OR 0.85, p = 0.01, 95% CI 0.744-0.961) were found to be an independent risk factor for CI from multivariate regression analysis. The accuracy of different CART parameters in the prediction of CI was described by the receiver operating curve (ROC) analysis. Regarding logistic regression model, we constructed formula of 15 - ([12 x Valsava maneuver] + [0.1 x deep breathing] + [0.2 x handgrip maneuver]) which will show negative and positive results indicating CI and non-CI, respectively. The resulting score showed good calibration and discriminatory capacity in the derivation (Hosmer-Lemeshow x² 10.051, p = 0.186, AUC = 0.878). The difference between AUCs in the derivation and validation sets was Δ =  0.122 (p = 0.174). Conclusion The decrease in heart rate variations during Valsava maneuver and deep breathing and in diastolic blood pressure during handgrip maneuver seems to be related to development of CI. Formula of CARTs score is a useful tool for predicting CI.

Abstract:Psychosocial risk factors significantly contribute to the morbidity and mortality of patients with cardiovascular disorders. The present study explored the anxiety and depression status of patients with coronary artery disease and evaluated the effect of deep breathing exercise on these psychosocial variables as well as physiological variables like heart rate variability and blood pressure. A randomized control design was adopted for the study. Out of 65 clients eligible for the study, 45 were selected based on inclusion criteria. Patient were trained in Deep breathing exercise (DBE)for 2-3 days, were instructed to practice the exercise twice a day for 10 min for a period of 2 weeks, further instructed to come for follow up to cardiac OPD after 2 weeks. The study findings revealed that majority of the cardiac patients were anxious 39 (86.66%), 23(57.5%) had mild depression and 3(7.5%) were with severe depression. Fischer's exact test revealed a significant association between depression and occupation (p=0.051), monthly income (p=0.031) and co morbid disease (p=0.006, p<0.05). Karl Pearson's correlation coefficient revealed significant positive correlation between anxiety and depression i.e. (r = 0.414, p <0.01). DBE was found to be effective in reducing anxiety and diastolic BP of clients with CAD. But there was no significant reduction in HR, SBP and depression after the intervention.
