Heart Disease: Abnormal Heart Rhythm

Positive and negative affect and risk of coronary heart disease: Whitehall II prospective cohort study. (BMJ. 2008) “Smoking, hypertension, hypercholesterolaemia, and diabetes are established risk factors for coronary heart disease, a leading cause of morbidity and mortality in Western industrialised countries.1 2 However, psychological factors, such as emotions, may also have a role in the development of coronary heart disease.3 4 Several prospective studies have found anxiety, hostility/anger, and depression to be associated with an increased risk of coronary heart disease in healthy participants.3 5 As the relative importance of these three negative emotions on risk of coronary heart disease remains largely undefined,6 7 they have been hypothesised to be the components of a single underlying factor, labelled negative affect. Negative affect refers to “stable and pervasive individual differences in mood and self-concept characterised by a general disposition to experience a variety of aversive emotional states.”5 8 High negative affect has been described as a general tendency to report “distress, discomfort, dissatisfaction, and feelings of hopelessness over time and regardless of the situation,” and low negative affect is characterised by “calmness and serenity.”8 9 Supporting this conceptualisation, a considerable neurobiological and psychological overlap between anxiety, hostility/anger, and depression has previously been shown.10 11 As attempts to link psychological factors to heart disease have focused on negative emotions, mostly depression,7 whether positive emotions might also have a role in the development of coronary heart disease remains unclear.“

Prediction of First Events of Coronary Heart Disease and Stroke With Consideration of Adiposity (Circulation. 2008) “Conclusions— Greater BMI, higher systolic blood pressure, higher ratio of cholesterol to high-density lipoprotein cholesterol, and presence of DM were all predictive of first CHD events, and all but the presence of DM were predictive of first CeVD events. These results suggest that common pathophysiological mechanisms underlie the roles of BMI, DM, and systolic blood pressure as predictors for first CHD and CeVD events.”
