Background: The relationship between the prognosis of patients with both chronic thromboembolic pulmonary hypertension (CTEPH) and a mental disorder (MD) remains unclear.
Methods and Results: The study group comprised 157 patients with CTEPH who underwent right heart catheterization and were subdivided into 2 groups according to the presence of MDs: MD and non-MD. The patients with MDs were defined as those who had visited a psychiatrist and were under psychotropic drug treatment. The primary outcome was a composite of all-cause death and worsening of PH. The median follow-up period was 1,164 days. The incidence of the primary composite outcome was higher in the MD group than in the non-MD group (24.0% vs. 6.8%), whereas the all-cause mortality rate was comparable between groups (12.0% vs. 6.1%). The mean pulmonary arterial pressure, cardiac index, and pulmonary vascular resistance at baseline were all similar between groups. The Cox proportional hazards model indicated that MD was an independent risk factor for the primary composite outcome (hazard ratio, 2.990; 95% confidence interval, 1.034–8.642).
Conclusions: In the present study, concomitant CTEPH and MD was significantly associated with a poor prognosis and such patients should be carefully followed.
