The present study examined the interaction between vital exhaustion and cardiac reactivity and recovery on preclinical atherosclerosis assessed by carotid intima-media thickness (IMT) in young men and women. We measured heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) in response to mental arithmetic and speech tasks. Vital exhaustion and carotid IMT were also measured. Significant associations were observed for men aged 28-37 years, but not for men aged 22-25 years, nor for women in these age groups. It was shown that, among highly exhausted men in the older age group, lower HR reactivity was related to greater IMT. Our results also imply that, among non-exhausted men in this age group, slow HR and RSA recovery after acute stress predicted higher IMT. These results suggest that long-term stress as assessed by vital exhaustion is a risk only if it has resulted in ineffective cardiac stress reactivity. Autonomic imbalance resulting from chronic stress may be the common mechanism linking vital exhaustion and cardiac responsiveness to an increased risk of atherosclerosis.

A history of intimate partner violence (IPV) is linked to cardiovascular disorders among women. Static autonomic nervous system (ANS) imbalance may result from chronic stress associated with exposure to IPV. Autonomic nervous system imbalance is associated with an excessive proinflammatory response that may increase the risk for inflammatory diseases, including atherosclerosis. To better understand the process from IPV to poorer health outcomes in women diagnosed with acute coronary syndrome (ACS) we developed and tested a biobehavioral model of the psychological and biological pathway from IPV to chronic illness. We hypothesized that among women hospitalized for ACS, those who reported sexual abuse, with or without physical abuse, would have greater alterations in their serum levels of neuroendocrine markers, proinflammatory cytokines, and cell adhesion molecules and a chemotactic cytokine, at time of hospitalization for ACS, and 3 and 6 months later, than do women with physical abuse only. Participants were 45 women, primarily African American, admitted to a county hospital with a diagnosis of ACS. We evaluated 11 biomarkers and found a moderate group effect size for vascular cell adhesion molecule-1. All others had a small effect size.

Autonomic imbalance, a feature of both diabetes and hypertension, may contribute to adverse cardiovascular outcomes. In animal models, sympathetic nerve activity contributes to renal damage but the extent to which autonomic dysfunction precedes the development of CKD and ESRD in humans is unknown. We measured resting heart rate and heart rate variability in 13,241 adults (45- to 64-years old) followed for a median of 16 years in the Atherosclerosis Risk in Communities (ARIC) Study. We examined heart rate parameters by quartiles, defining those in the lowest quartile (by time and frequency domain measures separately) as the risk group of interest. We identified 199 cases of incident ESRD and 541 patients with CKD-related hospitalizations; higher resting heart rate and lower heart rate variability associated with both outcomes. The fully adjusted hazard ratios for ESRD were 1.98 (95% confidence interval [CI] 1.45 to 2.70) among those in the highest heart rate quartile and 1.56 (95% CI 1.14 to 2.14) for high-frequency power. Other time and frequency domain measures were similarly and significantly associated with ESRD and CKD-related hospitalizations. These results suggest that autonomic dysfunction may be an important risk factor for ESRD and CKD-related hospitalizations and call for further studies to define the mechanisms that underlie these associations.
