Mental Health and Quality of Life in Pulmonary Embolism: A Literature Review

Pulmonary embolismis an acute disease with chronic complications and, although it is not considered a chronic disease, it requires close follow-up. The scope of the present literature review is to decode the existing data concerning quality of life and the mental health impact of PE during the acute and long-term phases of the disease. The majority of studies reported impaired quality of life in patients with PE when compared to population norms, both in the acute phase and >3 months after PE. Quality of life improves over time, irrespectively of the measurement used. Fear of recurrences, elderly, stroke, obesity, cancer and cardiovascular comorbidities are independently associated with worse QoL at follow-up. Although disease specific instruments exist (e.g., the Pulmonary Embolism Quality of Life questionnaire), further research is required in order to develop questionnaires that may fulfil international guideline requirements. The fear of recurrences and the development of chronic symptoms, such as dyspnea or functional limitations, may further impair the mental health burden of PE patients. Mental health may be implicated by post-traumatic stress disorder, anxiety and depressive symptoms present following the acute event. Anxiety may persist for 2 years following diagnosis and may be exaggerated by persistent dyspnea and functional limitations. Younger patients are at higher risk of anxiety and trauma symptoms while elderly patients and patients with previous cardiopulmonary disease, cancer, obesity or persistent symptoms exhibit more frequently impaired QoL. The optimal strategy for the assessment of mental health in this patient pool is not well defined in the literature. Despite mental burden being common following a PE event, current guidelines have not incorporated the assessment or management of mental health issues. Further studies are warranted to longitudinally assess the psychological burden and elucidate the optimal follow-up approach.
