Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Prospective memory and CAD Prospective memory (PM) is another facet of executive function that concerns the realization of an intended action (Kvavilashvili, 1998). In addition to the support from memory system, PM strongly relies on attentional and executive control (Kliegel et al., 2011). For example, the two-stage cue-focused view of PM retrieval (McDaniel et al., 2004) posited the importance of "noticing" an action cue before the associated memory search can be initiated. PM is a clinically relevant psychological construct as the failure has been related to quality of life (Doyle et al., 2012), activities of daily living (Woods et al., 2008) and medication adherence (Zogg et al., 2012).
However, little is known about PM function in CAD. Only Habota et al. (2015) reported significant PM deficit in a small group of chronic heart failure patients (N = 19) as compared to healthy controls (N = 24). Therefore, the first aim of the present study is to examine PM performance in people with CAD as compared to their healthy controls.
Prospective memory and cardiac function The association between the brain and the heart has long been recognized (Samuels, 2007). However, the mechanism of cognitive impairment in CAD has not been clearly understood. Researchers proposed several contributing pathological routes including increased platelet activity, thrombo-embolic mechanisms or cardiac output reduction (Abete et al., 2014). The neurovisceral integration model (Smith et al., 2017) proposed a hierarchy of vagal control from intra-cardiac and cardiovascular reactions to representation of multimodal prior expectations that involve the cerebral executive control network. Accumulating evidence supported this notion by demonstrating the link between autonomic nervous system (ANS) and behavioral performance, such as the association between heart rate variability (HRV) and cognitive functions (Forte et al., 2019) and its moderating effect of resting pre-ejection time (PEP; Giuliano et al., 2017).
Few studies investigated the relationship between autonomic responses and PM. Kliegel et al. (2007) and Rothen et al. (2014) verified that there was an association between increased skin conductance responses (SCRs) and the noticing of PM cues in young adults. More recently, Umeda et al. (2016) found that PM performance was associated with an increase in heart rate upon target presentation and with better interoceptive accuracy in college students. They hypothesized that PM was regulated by cardiac afferent signals that facilitate saliency detection and intention retrieval, which was also mediated by interoceptive accuracy. These preliminary findings suggest close relationship between PM and autonomic functions and provide another aspect of the evidence on the brain-heart connection.
However, the methodology adopted in these studies suffered from crude, indirect measures of ANS activity. It is also unclear if the autonomic nervous function compromised by CAD (Montano et al., 2009) would play a role in PM deficit. Hence, the second aim of the present study is to investigate the relationship between PM and cardiac function as measured by HF-HRV (the parasympathetic component) and PEP (the sympathetic component).
