Those Who Perceive Their Disease as a Physiological or Psychological Risk Factor Experience More Anxiety at the Beginning of the Cardiac Rehabilitation Program

In a cardiac patient, anxiety is the result of the individual's perception of the treatment and is characterized by inability to predict, control, or achieve the desired treatment outcomes. This study was carried out to investigate the extent of clinical anxiety in patients who underwent a cardiac rehabilitation program with different attitudes toward the disease risk factors. The administrative data of this retrospective study were obtained from the database of the cardiac rehabilitation department of a hospital in Iran. The demographic and clinical information of 603 patients from April 2006 to April 2011 was collected using compiled forms of this database, the Beck anxiety inventory, and the structured clinical interview for axis I disorders. The univariate analysis of variance and the Bonferroni post-hoc analysis were used for data analysis. After controlling for gender and educational level, we observed statistically significant differences in the modified means between the patients who considered the behavioral risk factors and those who considered the physiological risk factors (P = 0.012, MD = 5.03) and between the patients who regarded the behavioral risk factors and those who regarded the psychological risk factors (P = 0.0005, MD = 5.32) as the underlying cause of their cardiac condition, which means that the level of anxiety in the physiological and psychological groups was higher than that in the behavioral group. The anxiety of patients can be controlled through alteration in their attitudes toward the disease risk factors on the grounds that psychological or physiological factors per se do not trigger the occurrence of the disease, whereas behavioral risk factors, as the controlling agent, significantly influence its occurrence.
