The cognitive underpinnings of coronary-prone behaviors

Psychosocial Antecedents of Hostility in Persons with Coronary Heart Disease

Although it is known that hostility precedes coronary heart disease (CHD), little is known about factors that influence the development and progression of hostile characteristics. The relations among hostility, self-esteem, self-concept, and psychosocial residual were conceptualized within the modeling and role-modeling theoretical framework and examined in a sample of 85 persons with CHD. There were significant associations between all variables. Regression analyses revealed that self-esteem, mistrust residual, isolation residual, and self-concept contributed significantly, accounting for 31% of the variation in hostility scores. These findings provide support for the belief that the development of hostility in persons with CHD is related to beliefs and attitudes about the self and others. Persons with self-esteem need deficits, and a subsequent build up of negative psychosocial residual, have poor self-concepts. This poor self-concept is hostile in nature and reflects a mistrust of others and a deep sense of isolation.

Modification of physical activity 5 months after myocardial infarction: relevance of biographic and personality characteristics

The relation between modification of physical activity, a risk factor for coronary heart disease, and personality characteristics was assessed in 166 survivors of a first myocardial infarction (MI). Physical activity was assessed before MI in retrospect and again 5 months after MI. Patients were divided into 3 categories according to their current daily-life physical activities: less active than before MI (n=24), equally active as before MI (n=82), or more active than before MI (n=60). A significant differentiation was found between patients who became less physically active than before MI and the other 2 categories. This less active category was characterized by feelings of disability, a low level of vigor, and feelings of anxiety. In addition, this patient group was on average older and more often female. The results were adjusted for participation in a cardiac rehabilitation program. Finally, the discussion recommends involving psychological intervention in the exercise program for the less active category of patients to diminish feelings of anxiety and disability and to improve vigor.

Modification of smoking habits five months after myocardial infarction: relationship with personality characteristics

The relationship between personality characteristics and spontaneous modification of smoking habits was assessed in 164 patients after their first myocardial infarction (MI). Smoking habits before the MI were investigated in retrospect and 5 months later. Smoking appeared to have decreased significantly. Persistent smokers could be differentiated from nonsmokers and exsmokers by a significantly high level of state-anxiety and depression. Young persistent smokers had a high level of depression; elderly persistent smokers were highly anxious and had a low level of somatization. The relationship between smoking behaviour modification and personality characteristics is discussed in association with intervention programmes.
