To determine if improvement in mood would ameliorate autonomic dysregulation, HPA dysfunction, typical risk factors and C-reactive protein in depressed patients with elevated cardiovascular disease risk (CVD), 48 depressed participants with elevated cardiovascular risk factors were randomized to a cognitive behavioral intervention (CBT) or a waiting list control (WLC) condition. Twenty non-depressed age and risk-matched controls were also recruited. Traditional risk factors (e.g., lipids, blood pressure) and C-reactive protein were assessed pre- and post-treatment six months later. Subjects also underwent a psychophysiological stress test while cardiovascular physiology was measured. Salivary cortisol was measured during the day and during the psychological stress test. At post-treatment, the CBT subjects were significantly less depressed than WLC subjects. There was no significant difference in change scores on any of the traditional risk factors or C-reactive protein, cortisol measures, or cardiovascular physiology, except for triglyceride levels and heart rate, which were significantly lower in treatment compared to control subjects. The normal controls exhibited no change in the variables measured during the same time. A significant improvement in mood may have little impact on most traditional or atypical risk factors, cortisol or cardiophysiology.
This study examined the effect of a cognitive behavior therapy (CBT) therapy intervention designed to reduce depression in older patients with elevated cardiovascular disease (CVD) risk. Forty-eight depressed patients with elevated CVD were randomized to a 16-week individual CBT intervention (n = 23) or a wait-list control (WLC) group (n = 25). Pre- and post-treatment measures of depression were obtained during office visits, and measures of positive and negative affect were obtained during laboratory psychological stress testing and at five points during the day. At post-treatment, the CBT subjects were significantly less depressed than WLC subjects on the Hamilton Depression Inventory (F = 52.8, P<.001, ES = 1.85) and the Beck Depression Inventory (F = 17.1, P = <.001, ES = 0.85). Fifty-seven percent (13/23) of subjects in the CBT treatment were considered to be in remission (on the basis of a clinical interview) at post compared to only 4% (1/25) in the WLC (chi(2) = 9.0, P =.003). Treatment subjects reported significantly less stress on the Perceived Stress Scale (F = 23.2, P<.001). CBT significantly improved mean positive affect during the day (F = 12.7, P =.0001) but there were no significant differences in mean negative affect (F = 1.8, P =.19). CBT significantly reduced negative affect (F = 7.1, P =.01) during psychological stress testing but did not affect positive affect. CBT is an effective treatment for reducing depression and increasing positive affect in patients at risk for CVD, but the results vary by time of measurement and measurement setting.
The purpose of this study was to determine whether adolescent girls with panic attacks not selected on the basis of seeking treatment, have the associated symptomatology that characterizes patients with panic symptoms from clinical samples. The sample consisted of 713 sixth- and seventh-grade girls who were administered a structured interview and questionnaire to assess panic symptoms, agoraphobic avoidance, school refusal, depression, and substance use. The 40 subjects reporting panic attacks were matched for age, pubertal status, and ethnicity with 120 comparison subjects. School refusal and depressive symptoms were more common among those having experienced a panic attack compared with those in the matched comparison group. Agoraphobic avoidance and substance use were not associated with panic. If replicated, panic attacks should be considered in the differential diagnosis for young adolescent girls presenting with school refusal, particularly since adolescents rarely volunteer symptoms of panic.
