“…The resting heart rate influences autonomic control, and a higher resting heart rate is indicative of reduced parasympathetic activity. 23 , 24 , 25 , 26 , 27 , 28 , 29 In the present study, the average resting heart rate of overweight individuals was 70 beats per minute. Also, CAF fluctuates throughout the day and varies according to different activities, the regulation of hormones and muscle mass in an individual.…”

“…The autonomic nervous system plays a fundamental role in maintaining cell homeostasis and physiological function. The functionality of the heart and skeletal muscles is partially modulated by the sympathetic and parasympathetic branches of the autonomic nervous system both during rest and during exercise [ 32 ]. Patients with sarcopenia have higher muscle sympathetic nerve activity than those without sarcopenia and exhibited reduced parasympathetic-associated modulation, suggesting an adverse effect of sarcopenia on cardiac health [ 33 , 34 ].…”

Aim The purpose of the present study was to elucidate the relationship between high-frequency heart rate variability (HF HRV) and continuous daytime sitting time in patients with cardiovascular risk factors such as mild hypertension and/or stable angina pectoris. Background Decreased HF HRV precedes the progression and worsening of cardiovascular diseases. Continuous sitting behavior is a major risk factor for developing metabolic syndrome and is associated with cardiovascular disease, diabetes mellitus, renal failure, sarcopenia and osteoporosis. Risk factors for cardiovascular disease can be affected by continuous daytime sitting behaviors. Design The present study design was a post-hoc comparison. Methods Patients treated at two different primary care clinics from 2014 to 2018 were enrolled in this study (n = 53). We assessed HF HRV and continuous sitting time using 24-hour Holter electrocardiography and an activity meter at baseline and 6 months. HF HRV was calculated during sleep. Results Sitting time had decreased in 22 patients (decreased group) and increased in 31 patients (increased group) after 6 months. The mean patient ages were 73.1 and 72.0 years in the decreased and increased sitting time groups, respectively (p = 0.503). HF HRV during sleep had increased after 6 months in the decreased sitting time group. Compared with the increased group, the decreased group showed significantly higher HF HRV during sleep after 6 months by two-way repeated-measures ANOVA after adjustment for age, sex and change in activity (p = 0.045). Conclusion These results suggest that a decrease in sitting time might induce parasympathetic activity during sleep. Therefore, reducing continuous sitting time during the day might contribute, in part, to improving the prognosis of patients with cardiovascular risk factors not only by avoiding muscle loss but also by providing positive influences on parasympathetic tone during sleep.

Aim. To investigate the relationship between the osmotic fragility of erythrocytes and the course of acute myocardial infarction (MI).Methods. An analysis of the osmotic fragility of erythrocytes was conducted using beta-blocker-based osmotic fragility test in sixty-two patients within the first 6 hours after onset of MI symptoms.Results. The results revealed that the patients with increased erythrocyte osmotic fragility experienced more complications after acute MI, such as left ventricular failure and cardiac arrhythmias (ventricular extrasystoles and ventricular tachycardia) (p = 0.026). Moreover, these patients exhibited greater myocardial injury - the concentration of biomarkers of myocardial necrosis, such as creatine phosphokinase, creatine phosphokinase MB and Troponin I was increased - p = 0.009, p = 0.032 and p = 0.001, respectively. In addition to that, the patients with high osmotic fragility had a larger number of hypokinetic and akinetic segments, high impaired myocardial contractility index, and low ejection fraction. The impaired myocardial contractility index was significantly higher in patients with increased erythrocyte osmotic fragility (1.5 (1.22; 1.75) vs 1.12 (1.0; 1.56), U = 157.5, p = 0.032).Conclusion. Increased erythrocyte osmotic fragility in patients was associated with greater myocardial injury, manifesting through the higher concentration of biomarkers of myocardial necrosis in blood, as well as higher number of hypokinetic segments.
