ABSTRACT
OBJECTIVES: The EXhaustion Intervention Trial investigated the effect of a behavioural intervention programme on exhaustion, health-related quality of life (HRQL), depression, anxiety, hostility, and anginal complaints in angioplasty patients who felt exhausted after percutaneous coronary intervention (PCI). METHODS: Seven hundred ten patients were randomized into an intervention group and a usual care control group. The group intervention focused on stressors leading to exhaustion and on support of recovery. HRQL (measured by the MacNew questionnaire), exhaustion [measured by the Maastricht Questionnaire and the Maastricht Interview Vital Exhaustion (MIVE)], anxiety (measured by the State-Trait Inventory), and depression (measured by the structured clinical interview for DSM-IV) were assessed at intake and at 6 and 18 months. Presence of anginal complaints was assessed at 18 months. RESULTS: The intervention had a significant beneficial effect on all psychological factors except hostility and on the presence of anginal complaints. The effect of the intervention on exhaustion, as assessed by the MIVE, was modified by a previous history of coronary artery disease (CAD). Gender modified the effect of the intervention on exhaustion and on anxiety, the strongest effect being observed in women. CONCLUSIONS: The behavioural intervention improved HRQL and related psychological factors. Somatic comorbidity and a history of CAD limited the effect of the intervention.

BACKGROUND: Extreme fatigue is a common complaint in percutaneous coronary intervention (PCI) patients, and is associated with an increased risk for new cardiac events. The objective of the Exhaustion Intervention Trial (EXIT) was to determine whether a behavioral intervention on exhaustion reduces the risk of a new coronary event after PCI. METHODS AND RESULTS: Seven hundred ten consecutive patients, ages 35 to 68 years, who felt exhausted after PCI were randomized into an intervention group and a usual-care group. The intervention was based on group therapy focusing on stressors leading to exhaustion, and on support for recovery by promoting rest and making rest more efficient. One month after PCI, 50% of the patients felt exhausted. The intervention reduced the odds of remaining exhausted at 18 months by 56% in those without a previous history of coronary artery disease (CAD) (OR = 0.44; 95% CI 0.29-0.66), but had no effect on exhaustion in those with a history of CAD (OR = 0.93; 95% CI 0.56-1.55; p = .78). The intervention did not reduce the risk of a new coronary event within 2 years (RR = 1.14; 95%CI 0.82-1.57). Post-hoc analyses suggest that the effect of the intervention was limited by a positive history of CAD, the presence of a chronic, painful condition (especially rheumatism), and by opposite effects on early and late cardiac events. CONCLUSION: A behavioral intervention in PCI patients has a beneficial effect on feelings of exhaustion. It could not be demonstrated that the intervention reduces the risk of a new coronary event within 2 years.
