Relationship between Cardiovascular Fitness and Arterial Stiffness, Heart Rate Variability, Quality of Sleep in Middle-aged Male Firefighters

Abstract Death of a significant other is consistently found to have a detrimental effect on cardiovascular functioning, and such relationship may be stronger when loss is accompanied by low-quality sleep. Using data from the Biomarker project of Midlife in the United States study (n=1,310), we examined whether quality-of-sleep has an additive effect on the relationship between loss and heart rate variability (HRV). Loss was measured as losing someone close within a year of data collection, and was categorized based on the respondents’ relationship with the deceased. Relationship was categorized as: immediate family, relative, and friend. Quality-of-sleep was measured using the Pittsburgh Sleep Quality scale. Results showed that the associations among loss, sleep, and HRV differed by gender. For women, losing an immediate family was associated with worse HRV and this did not differ by quality-of-sleep. For men, death of an immediate family was associated with worse HRV only among those with poorer quality sleep. These results suggest that low-quality sleep may indicate psychophysical vulnerability for men who experienced loss, which may relate to their lower capacity for physiological adaptation.

Female Nurses

The quality of nurses’ work has a direct effect on patient health, and poor sleep has been positively associated with nurses’ medical errors. The aim of this study was to investigate the relationship between quality of sleep and heart rate variability (HRV) among female nurses. A descriptive cross-sectional correlational study design was used in January 2014 to study female nurses (n = 393) employed in a medical center in Taiwan. Data were obtained from several questionnaires. HRV was analyzed with five-minute recordings of heart rate signals obtained using a Heart Rater SA-3000P. Approximately 96% of the participants self-reported a poor quality of sleep. Compared to non-shift nurses, significant decreases were found in total power (TP) and low-frequency HRV among shift-work nurses. However, negative correlations were found between sleep quality and HRV, including total power, low frequency, and the low frequency/high frequency ratio (r = −0.425, p < 0.05; r = −0.269, −0.266, p < 0.05). In a stepwise multiple regression analysis, 23.1% of variance in quality of sleep can be explained by TP and heart rate. The sleep quality of female nurses was poor and this affected their autonomic nervous system, which can contribute unfavorable consequences for their health.

Healthy Women

Diabetes confers greater cardiovascular risk to women than to men. Whether insulin-resistance-mediated risk extends to the healthy population is unknown. Measures of insulin resistance (fasting insulin, homeostatic model assessment, hemoglobin A1c, quantitative insulin sensitivity check index, glucose) were determined in 48 (56% female) healthy subjects. Heart rate variability (HRV) was calculated by spectral power analysis and arterial stiffness was determined using noninvasive applanation tonometry. Both were measured at baseline and in response to angiotensin II infusion. In women, there was a non-statistically significant trend towards increasing insulin resistance being associated with an overall unfavourable HRV response and increased arterial stiffness to the stressor, while men demonstrated the opposite response. Significant differences in the associations between insulin resistance and cardiovascular physiological profile exist between healthy women and men. Further studies investigating the sex differences in the pathophysiology of insulin resistance in cardiovascular disease are warranted.
