Background: Pulmonary thromboendarterectomy (PTE) is a recognized treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), with good long-term hemodynamic results. The aim of this study was to test the hypothesis that the dynamics of health-related quality of life (QoL), 1 year after PTE, depend both on the clinical determinants associated with the underlying disease and the adverse events occurring in the early postoperative period.
Methods: This prospective cohort study included 136 patients with CTEPH. All patients before and after PTE (1-year follow-up) were examined in terms of QoL, by using the Short Form 36 Health Survey Questionnaire.
Results: One year after PTE, a significant improvement in the QoL of patients was observed in all subscales of the Short Form 36 Health Survey Questionnaire, except in the general health scale. Multivariate analysis showed that the predictors adversely affecting the dynamics of QoL after PTE were the presence of comorbidities (such as chronic obstructive pulmonary disease [COPD] and coronary artery disease) and early postoperative complications (specific ones for this category of patients are residual pulmonary hypertension and neurological complications, and nonspecific ones are atrial fibrillation and heart failure).
Conclusions: The determinants that affect the dynamics of QoL 1 year after PTE in patients with CTEPH were the presence of comorbidities (COPD and coronary artery disease) and adverse events in the early postoperative period (residual pulmonary hypertension, neurological complications, atrial fibrillation, and heart failure).
