Women's exhaustion and coronary artery atherosclerosis progression: The Stockholm Female Coronary Angiography Study.

OBJECTIVE: Vital exhaustion (VE) has been associated with incident and recurrent cardiac events. The present study investigated the impact of VE on coronary atherosclerosis progression for 3 years. We further aimed to detect the relative importance of the VE subcomponents, fatigue, and depressed mood. METHODS: 103 women (age range, 30-65 years) who had experienced an acute coronary event underwent quantitative coronary angiography at baseline and again after 3 years. VE and subcomponents were assessed using the Maastricht Questionnaire. RESULTS: VE correlated significantly with coronary artery diameter change for 3 years (r = -0.239, p = .015). When analyzed in quartiles, women of the highest VE level showed the most pronounced coronary artery luminal diameter narrowing (mean = 0.21 mm, 95% confidence interval [CI] = 0.15-0.27), women in the third quartile were intermediate (mean = 0.11 mm, 95% CI = 0.05-0.17), and women within the two lower quartiles showed no significant change. High levels of the depressed mood and fatigue subscales were also associated with coronary artery diameter narrowing (mean = 0.19 mm, 95% CI = 0.12-0.26, p = .003; and mean = 0.17 mm, 95% CI = 0.08-0.26, p = .03, respectively). However, the associations were attenuated when both variables were entered into the model simultaneously: 0.17 mm (95% CI = 0.09-0.25, p = .05) and 0.14 mm (95% CI = 0.03-0.25, p = .67), respectively. CONCLUSIONS: VE was associated with accelerated coronary atherosclerosis progression in relatively young women who had experienced an acute coronary event. This association was mainly driven by depressed mood.
