Background: Cardiopulmonary exercise testing (CPET) may provide prognostically valuable information during follow-up after pulmonary embolism (PE). Our objective was to investigate the association of patterns and degree of exercise limitation, as assessed by CPET, with clinical, echocardiographic and laboratory abnormalities and quality of life (QoL) after PE.Methods: In a prospective cohort study of unselected consecutive all-comers with PE, survivors of the index acute event underwent 3- and 12-month follow-ups, including CPET. We defined cardiopulmonary limitation as ventilatory inefficiency or insufficient cardiocirculatory reserve. Deconditioning was defined as peak O2uptake (V′O2) <80% with no other abnormality.Results: Overall, 396 patients were included. At 3 months, prevalence of cardiopulmonary limitation and deconditioning was 50.1% (34.7% mild/moderate; 15.4% severe) and 12.1%, respectively; at 12 months, it was 44.8% (29.1% mild/moderate; 15.7% severe) and 14.9%, respectively. Cardiopulmonary limitation and its severity were associated with age (OR per decade 2.05, 95% CI 1.65–2.55), history of chronic lung disease (OR 2.72, 95% CI 1.06–6.97), smoking (OR 5.87, 95% CI 2.44–14.15) and intermediate- or high-risk acute PE (OR 4.36, 95% CI 1.92–9.94). Severe cardiopulmonary limitation at 3 months was associated with the prospectively defined, combined clinical-haemodynamic end-point of “post-PE impairment” (OR 6.40, 95% CI 2.35–18.45) and with poor disease-specific and generic health-related QoL.Conclusions: Abnormal exercise capacity of cardiopulmonary origin is frequent after PE, being associated with clinical and haemodynamic impairment as well as long-term QoL reduction. CPET can be considered for selected patients with persisting symptoms after acute PE to identify candidates for closer follow-up and possible therapeutic interventions.

Acute right ventricular failure is a complex and rapidly progressive clinical syndrome, whereby the right ventricle fails to provide adequate left ventricular preload, dilates, and causes systemic venous congestion. Previous research in acute heart failure has primarily focused on the left ventricle. Yet, the need for a better understanding of right ventricular anatomy, physiology, and pathophysiology, as well as of the diagnosis and management of its acute failure is crucial. Diagnosis mandates a high degree of clinical suspicion, as the majority of signs and symptoms are nonspecific. An accurate and prompt identification of the underlying causes, including pulmonary embolism, right ventricular myocardial infarction, acute respiratory distress syndrome, post-cardiac surgery, and decompensated chronic pulmonary hypertension, is therefore essential. This review provides insights into right ventricular anatomy and functioning and discusses the pathophysiology of acute right ventricular failure, its differential aetiologies, clinical presentation, diagnosis, and treatment.

Background: As mortality from pulmonary embolism (PE) decreases, the personal and societal costs among survivors are receiving increasing attention. Detailing this burden would support an efficient public health resource allocation. We aimed to provide estimates for the economic and disease burden of PE also accounting for long‐term health care use and both direct and indirect costs beyond the acute phase. Methods and Results: This is a cost‐of‐illness analysis with a bottom‐up approach based on data from the PREFER in VTE registry (Prevention of Thromboembolic Events—European Registry in Venous Thromboembolism). We calculated direct (clinical events and anticoagulation) and indirect costs (loss of productivity) of an acute PE event and its 12‐month follow‐up in 2020 Euros. We estimated a disability weight for the 12‐month post‐PE status and corresponding disability adjusted life years presumably owing to PE. Disease‐specific costs in the first year of follow‐up after an incident PE case ranged between 9135 Euros and 10 620 Euros. The proportion of indirect costs was 42% to 49% of total costs. Costs were lowest in patients with ongoing cancer, mainly because productivity loss was less evident in this already burdened population. The calculated disability weight for survivors who were cancer free 12 months post‐PE was 0.017, and the estimated disability adjusted life years per incident case were 1.17. Conclusions: The economic burden imposed by PE to society and affected patients is considerable, and productivity loss is its main driver. The disease burden from PE is remarkable and translates to the loss of roughly 1.2 years of healthy life per incident PE case.

Background: Although a high prevalence of pulmonary embolism (PE) has been reported in association with coronavirus disease 2019 (COVID-19) in critically ill patients, nationwide data on the outcome of hospitalised patients with COVID-19 and PE are still limited. Thus, we investigated seasonal trends and predictors of in-hospital death in patients with COVID-19 and PE in Germany.Methods: We used a German nationwide inpatient sample to analyse data on hospitalisations among COVID-19 patients with and without PE during 2020, and to detect changes in PE prevalence and case fatality in comparison with 2019.Results: We analysed 176 137 COVID-19 hospitalisations in 2020; PE was recorded in 1.9% (n=3362) of discharge certificates. Almost one-third of patients with COVID-19 and PE died during the in-hospital course (28.7%) compared with COVID-19 patients without PE (17.7%). Between 2019 and 2020, numbers of PE-related hospitalisations were largely unchanged (98 485versus97 718), whereas the case fatality rate of PE increased slightly in 2020 (from 12.7% to 13.1%; p<0.001). Differences in case fatality were found between PE patients with and without COVID-19 in 2020 (28.7%versus12.5%; p<0.001), corresponding to a 3.1-fold increased risk of PE-related death (OR 3.16, 95% CI 2.91–3.42; p<0.001) in the presence of COVID-19.Conclusions: In Germany, the prevalence of PE events during hospitalisations was similar in 2019 and 2020. However, the fatality rate among patients with both COVID-19 and PE was substantially higher than that in those with only one of these diseases, suggesting a life-threatening additive prognostic impact of the COVID-19–PE combination.
