Abstract:Anxiety and emotional sensitivity were significant predictors of 8-year cardiac mortality after AMI. Reduced HF power, a recognized marker of vagal withdrawal, increased the risk.
“…Time domain measures; SDNN [9,10], RMSSD [28] and frequency domain measures; HF [7,15] and LF [3,13,27] all hold prognostic value for CAD patients.…”
This is the first study to show significant increases in raw LF and HF power derived from short-term ECG recordings in CR patients. These measures are risk factors for future cardiac event. As CR is associated with increases in these measures it may be viewed as an effective therapy capable of bringing about favourable alterations in autonomic control.

“…It should be noted that the latter study was cross-sectional and did not evaluate the relative impact of inhibition and HRV on health outcomes. However, a more recent study conducted in MI patients puts into question whether HRV mediates the relationship between inhibition and clinical outcome, as both social inhibition and impaired HRV were independent risk factors for mortality and non-fatal MI at 8 years follow-up [43]. Of note, patients with both risk factors had a substantially higher mortality rate (62%) compared with patients with no risk factors (6%) [43].…”

Abstract:The distressed personality (Type D) is an emerging risk factor in cardiovascular disease (CVD) that incurs a risk on par with left ventricular dysfunction in patients with ischemic heart disease. Type D is defined as the co-occurring tendencies to experience increased negative emotions and to inhibit self-expression in social interactions. Evidence is accumulating that Type D may also be a risk factor for adverse outcome across CVD patient groups, including patients undergoing revascularization with drug-eluting stent implantation or bypass surgery, patients with heart failure, peripheral arterial disease, and arrhythmia. In these patient groups, Type D personality has been associated with a 2-5 fold increased risk of adverse prognosis, impaired quality of life and symptoms of anxiety and depression independent of traditional biomedical risk factors, including disease severity. Although little is known about the pathways responsible for the detrimental effects of Type D on clinical outcome, the immune system and health-related behaviors, such as smoking and noncompliance, are likely candidates. Further research is warranted to investigate whether Type D personality is here to stay as a risk factor for CVD, but weighing current evidence on Type D against a set of external criteria shows that Type D personality fulfills the majority of these criteria. Importantly, Type D can easily be assessed in clinical research and practice with the standardized and validated DS14.
“…Ode et al (2010) reported that HRV was not associated with Neuroticism, though only used a brief ten-item scale to represent the more multifactorial construct of Neuroticism. Carpeggiani et al (2005) reported only one positive correlation between eight HRV measures and Cattell's 16 personality factors (insecurity and tension). Using the Tridimensional Personality Questionnaire, Huang et al (2013) found few significant relationships between five HRV indices and 15 personality subscales, even when males and females were examined in isolation, with only a 'harm avoidance' subscale returning a significant negative correlation.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
