Abstract
Abstract Laboratory studies with CHD patients suggest an adverse influence of emotional/mental arousal on myocardial ischaemia or ventricular premature contractions (VPCs). However, it is controversial whether such studies can be generalized to everyday life. In addition, existing ambulatory monitoring studies have shortcomings because emotional arousal is entirely based on subjective reports. The hypothesis of the present study is that during ischaemic episodes or VPCs “objective emotional/mental arousal” will be more pronounced than during comparable episodes without these events. Objective emotional/mental arousal was indicated by a special ambulatory monitoring method which was based on the online analysis of heart rate and physical activity, resulting in the so-called emotional or non-metabolic heart rate. Moreover, the method allowed for ratings of anginal pain. In 223 CHD patients the associations between ischaemia, VPCs, objective emotional/mental arousal, and anginal pain were investigated. Forty-nine patients revealed ischaemic episodes and 115 patients VPCs. Emotional/mental arousal was higher during ischaemic episodes as compared to control minutes whereas minutes with VPCs showed no difference. No differences between ischaemic episodes or VPCs and the respective control minutes were observed for anginal pain. Objective emotional/mental arousal was associated in this study with ischaemia but not with arrhythmia, thus partly confirming the hypothesis stated. Because anginal pain was not related to objective cardiac events, detection of CHD has to rely on medical examinations.
