Show moreBackground: Both chronic obstructive pulmonary disease (COPD) and right ventricular (RV) dysfunction are common factors that have been associated with poor prognosis after aortic valve replacement (AVR). Since there is still uncertainty about the impact of COPD on RV function and dilatation in patients undergoing AVR, we sought to explore RV function and remodeling in the presence and absence of COPD as well as their prognostic implications. Methods: Patients who received surgical or transcatheter AVR due to severe AS were screened for COPD. Demographic and clinical data were collected at baseline while echocardiographic measurements were performed at baseline and 1 year after AVR. The study end-point was all-cause mortality. Results: In total 275 patients were included, with 90 (33%) patients having COPD. At 1-year follow-up, mild worsening of tricuspid annular planar systolic excursion and RV dilatation were observed in patients without COPD, while there were significant improvements in RV longitudinal strain, RV wall thickness but dilatation of RV outflow tract distal dimension in the COPD group compared to the baseline. On multivariable analysis, the presence of COPD provided significant incremental prognostic value over RV dysfunction and remodeling. Conclusions: At 1-year after AVR, RV function and dimensions mildly deteriorated in non-COPD group whereas COPD group received significant benefit of AVR in terms of RV function and hypertrophy. COPD was independently associated with >2-fold all-cause mortality and had incremental prognostic value over RV dysfunction and remodeling. Show less

Show morePatients with chronic obstructive pulmonary disease (COPD) may benefit from palliative care including advance care planning, because of their severe symptom burden and high mortality rates. However, this care is poorly implemented due to various reasons. Therefore, this thesis aimed to study the effectiveness of palliative care for patients with COPD and how a palliative care approach can be successfully integrated into regular COPD care.A national survey among pulmonologists and general practitioners was conducted to identify the current content and organization of palliative care in COPD in the Netherlands (Chapter 2). A systematic review revealed that very little was known about the effectiveness of palliative care interventions in COPD and how best to implement it in practice (Chapter 3). To close this knowledge gap, the COMPASSION study was designed (Chapter 4). In a cluster randomized controlled trial in eight hospital regions, health care providers of intervention regions were trained to identify palliative patients with COPD using the ProPal-COPD tool, do advance care planning conversations, and manage dyspnea. The effectiveness on patient outcomes was studied (Chapter 5) and factors for successful implementation identified (Chapter 6). Finally, the ProPal-COPD tool was externally validated and user experiences examined (Chapter 7). Show less

Show moreAlthough COPD was originally thought to merely affect the airways and lungs, the attention of research has been shifted towards the high prevalence of cardiovascular disease in patients with COPD. Up to one third of deaths in patients with COPD can be attributed to a cardiovascular cause. In particular, a strong association between COPD and acute myocardial infarction (AMI) has been emphasized and the need for adequate risk stratification in this population has been recognized. Identification of patients at risk of adverse events after AMI is frequently performed with cardiac imaging. Echocardiography permits early assessment of left- and right ventricular size and function, as surrogates of cardiac damage in the acute phase. Emerging advanced echocardiographic techniques such as speckle tracking strain imaging enable characterization of myocardial mechanics, which have been associated with prognosis. Assessment of left- and right ventricular longitudinal strain in patient with COPD might provide better risk stratification as compared to conventional echocardiographic parameters. COPD is also a known risk factor for atrial fibrillation. Structural atrial remodeling, particularly of the right atrium, is suggested to be an important pathophysiologic substrate. Echocardiography may provide an additional tool in characterization of atrial structure and function, leading to targeted treatments. Show less

Show moreObjectives: Little direction exists on how to effectively implement palliative care for patients with COPD. In the COMPASSION study, we developed, executed, and evaluated a multifaceted implementation strategy to improve the uptake of region-tailored palliative care intervention components into routine COPD care. We evaluated the implementation strategy and assessed the implementation process, barriers, and facilitators. Methods: A mixed methods process evaluation was performed. Primary and secondary healthcare providers in four hospital regions in the Netherlands were trained. Patients identified during hospitalisation for an acute exacerbation received palliative care and were followed for a year. Various sources were used: process data, questionnaires including the End-of-life Professional Caregiver Survey (EPCS), medical records, monitoring meetings, and interviews. The Consolidated Framework of Implementation Research (CFIR) was used to categorize implementation determinants. Results: The training sessions with roleplay were positively evaluated and increased professionals' self-efficacy in providing palliative care statistically significantly. Of 98 patients identified, 44 (44.9%) received one or more palliative care conversations at the outpatient clinic. Having those conversations was highly valued by healthcare providers because it led to clarity and peace of mind for the patient and higher job satisfaction. Coordination and continuity remained suboptimal. Most important barriers to implementation were time constraints, the COVID-19 pandemic, and barriers related to transmural and interdisciplinary collaboration. Facilitators were the systematic screening of patients for palliative care needs, adapting to the patient's readiness, conducting palliative care conversations with a pulmonologist and a COPD nurse together, and meeting regularly with a small team led by a dedicated implementation leader. Conclusions: Providing integrated palliative care for patients with COPD is highly valued by healthcare providers but remains challenging. Our findings will guide future implementation efforts. Future research should focus on how to optimize transmural and interdisciplinary collaboration. Show less

Show moreBackground: Although antibiotic treatment is recommended for acute exacerbations of chronic obstructive pulmonary disease (AECOPD), its value in real-world settings is still controversial. Objectives: This study aimed to evaluate the short- and long-term effects of antibiotic treatment on AECOPD outpatients. Methods: A cohort study was conducted under the PharmLines Initiative. We included participants with a first recorded diagnosis of COPD who received systemic glucocorticoid treatment for an AECOPD episode. The exposed and reference groups were defined based on any antibiotic prescription during the AECOPD treatment. The short-term outcome was AECOPD treatment failure within 14-30 days after the index date. The long-term outcome was time to the next exacerbation. Adjustment for confounding was made using propensity scores. Results: Of the 1,105 AECOPD patients, antibiotics were prescribed to 518 patients (46.9%) while 587 patients (53.1%) received no antibiotics. The overall antibiotic use was associated with a relative risk reduction of AECOPD treatment failure by 37% compared with the reference group (adjusted odds ratio [aOR] 0.63 [95% CI: 0.40-0.99]). Protective effects were similar for doxycycline, macrolides, and co-amoxiclav, although only the effect of doxycycline was statistically significant (aOR 0.53 [95% CI: 0.28-0.99]). No protective effect was seen for amoxicillin (aOR 1.49 [95% CI: 0.78-2.84]). The risk of and time to the next exacerbation was similar for both groups. Conclusion: Overall, antibiotic treatment, notably with doxycycline, supplementing systemic glucocorticoids reduces short-term AECOPD treatment failure in real-world outpatient settings. No long-term beneficial effects of antibiotic treatment on AECOPD were found for the prevention of subsequent exacerbations. Show less

Show moreAims Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes.Methods and results Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes.Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002).Conclusions The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome. Show less

Show moreBackground:Although guidelines recommend palliative care for patients with chronic obstructive pulmonary disease, there is little evidence for the effectiveness of palliative care interventions for this patient group specifically.Aim:To describe the characteristics of palliative care interventions for patients with COPD and their informal caregivers and review the available evidence on effectiveness and implementation outcomes.Design:Systematic review and narrative synthesis (PROSPERO CRD42017079962).Data sources:Seven databases were searched for articles reporting on multi-component palliative care interventions for study populations containing > 30% patients with COPD. Quantitative as well as qualitative and mixed-method studies were included. Intervention characteristics, effect outcomes, implementation outcomes and barriers and facilitators for successful implementation were extracted and synthesized qualitatively.Results:Thirty-one articles reporting on twenty unique interventions were included. Only four interventions (20%) were evaluated in an adequately powered controlled trial. Most interventions comprised of longitudinal palliative care, including care coordination and comprehensive needs assessments. Results on effectiveness were mixed and inconclusive. The feasibility level varied and was context-dependent. Acceptability of the interventions was high; having someone to call for support and education about breathlessness were most valued characteristics. Most frequently named barriers were uncertainty about the timing of referral due to the unpredictable disease trajectory (referrers), time availability (providers) and accessibility (patients).Conclusion:Little high-quality evidence is yet available on the effectiveness and implementation of palliative care interventions for patients with COPD. There is a need for well-conducted effectiveness studies and adequate process evaluations using standardized methodologies to create higher-level evidence and inform successful implementation.

Show moreBackground Cognitive and motor-performance decline with age and the process is accelerated by decline in general health. In this study, we aimed to estimate the effects of COPD and HB levels on cognitive and motor performance in the general older population and assess potential interaction. Methods The English Longitudinal Study of Aging is a population-based cohort study including measurements of lung-function and HB levels together with cognitive and motor performance testing. Data were collected from 5709 participants including three measurement time over eight years. COPD was defined using lung-function-parameters and clinical symptoms. HB was assessed continuously and low HB was defined using clinical anemia cutoffs. Linear mixed-effects regression models were used to quantify the associations of COPD and HB with outcome measures, both individually and in combination. Results Participants with both low HB and COPD demonstrated worse motor performance compared to individuals with only one exposure, resulting in up to 1 s (95%CI, 0.04-1.8) longer time needed to complete the five times sit to stand task than what would be expected based on purely additive effects. Additionally in individuals with COPD, the time to complete the motor-performance task per unit decrease in continuous HB levels was longer than in participants without COPD after full adjustment for confounding (up to 1.38 s/unit HB level, 95% CI: 0.65-2.11). Conclusion In persons with COPD low HB levels may contribute to low motor-performance in a supra additive fashion. Further studies should re-evaluate whether earlier treatment of lower HB in these individuals might be beneficial. Show less

Show moreBackground: Right ventricular (RV) systolic function in patients admitted with ST-segment elevation myocardial infarction (STEMI) with chronic obstructive pulmonary disease (COPD) and its impact on prognosis have not been characterized. The present study aims to compare the prevalence of RV systolic dysfunction in COPD versus non-COPD patients with STEMI and evaluate the prognostic implications.Methods: One hundred seventeen STEMI patients with COPD with transthoracic echocardiography performed within 48 hours of admission were retrospectively selected. Matched on age, gender, and infarct size (determined by cardiac biomarkers and left ventricular ejection fraction [LVEF]), 207 non-COPD patients were selected. RV dysfunction was defined based on tricuspid annular plane systolic excursion <17 mm (TAPSE), tricuspid annular systolic velocity <6 cm/s (S'), RV fractional area change <35% (FAC), and RV longitudinal free wall strain (FWSL) measured with speckle-tracking echocardiography >-20%. Patients were followed for the occurrence of all-cause mortality.Results: RV assessment was feasible in 112 COPD and 199 non-COPD patients (mean age, 69 +/- 10; 74% male; mean, LVEF 47% +/- 8%). Patients with COPD had significantly lower RV FAC (38% +/- 11% vs 40% +/- 9%; P = .04), equal TAPSE and S' (17.9 +/- 3.7 vs 18.1 +/- 3.8 mm, P = .72; and 8.4 +/- 2.2 vs 8.5 +/- 2.2 cm/sec, P = .605, respectively) and more impaired RV FWSL (-21.1% +/- 6.6% vs -23.4% +/- 6.5%, P = .005), compared with patients without COPD. RV dysfunction was more prevalent in patients with COPD, particularly when assessed with RV FWSL (46% vs 32%; P = .021). During a median followup of 30 (interquartile range 1.5-44) months, 49 patients died (16%). Multivariate models stratified for COPD status showed that RV FWS >-20% was independently associated with 5-year all-cause mortality (hazard ratio, 2.05; 95% CI, 1.12-3.76; P = .020), after adjusting for age, diabetes, peak troponin level, and LVEF. Interestingly, RV FAC < 35%, S'< 6 cm/sec, and TAPSE < 17 mm were not independently associated with survival.Conclusion: In a STEMI population with relatively preserved LVEF, COPD patients had significantly worse RV FWSL compared with patients without COPD. Moreover, RV FWSL > -20% was independently associated with worse survival. In contrast, conventional parameters were not associated with survival. Show less

Show moreChronic obstructive pulmonary disease (COPD) is a chronic lung disease, characterised by inflammation and destruction of the airways. There are no curative options yet. However, COPD is a treatable disease, whereby reduction of symptoms is a major treatment goal. In this thesis, we focussed on morning symptoms. The relation between morning symptoms and physical activity was studied in search of novel treatment options. We concluded in a systematic review that there was a negative association between morning symptoms and self-reported physical activity. We confirmed this association in the MOrning symptoms in-Depth observationAl Study (MODAS), an observational cross-sectional study, in which we objectively measured physical activity. We also found that patients with high morning symptom scores took fewer steps in morning and afternoon than those with low morning symptom scores, but not during evening and night. These factors can be used as targets in future interventional studies. A subsequent real life study showed that participating physicians recorded more symptoms and lifestyle advises when a designated approach was used. To pay more attention to morning symptoms and physical activity in clinical practice, we encourage the use of a systematic approach that includes these items. Show less
