Establishing minimally important differences for cardiac MRI end-points in pulmonary arterial hypertension.

BACKGROUND: Cardiac magnetic resonance (CMR) is the gold standard technique to assess biventricular volumes and function, and is increasingly being considered as an end-point in clinical studies. Currently, with the exception of right ventricular (RV) stroke volume and RV end-diastolic volume, there is only limited data on minimally important differences (MIDs) reported for CMR metrics. Our study aimed to identify MIDs for CMR metrics based on US Food and Drug Administration recommendations for a clinical outcome measure that should reflect how a patient "feels, functions or survives". METHODS: Consecutive treatment-naïve patients with pulmonary arterial hypertension (PAH) between 2010 and 2022 who had two CMR scans (at baseline prior to treatment and 12 months following treatment) were identified from the ASPIRE registry. All patients were followed up for 1 additional year after the second scan. For both scans, cardiac measurements were obtained from a validated fully automated segmentation tool. The MID in CMR metrics was determined using two distribution-based (0.5sd and minimal detectable change) and two anchor-based (change difference and generalised linear model regression) methods benchmarked to how a patient "feels" (emPHasis-10 quality of life questionnaire), "functions" (incremental shuttle walk test) or "survives" for 1-year mortality to changes in CMR measurements. RESULTS: 254 patients with PAH were included (mean±sd age 53±16 years, 79% female and 66% categorised as intermediate risk based on the 2022 European Society of Cardiology/European Respiratory Society risk score). We identified a 5% absolute increase in RV ejection fraction and a 17 mL decrease in RV end-diastolic or end-systolic volumes as the MIDs for improvement. Conversely, a 5% decrease in RV ejection fraction and a 10 mL increase in RV volumes were associated with worsening. CONCLUSIONS: This study establishes clinically relevant CMR MIDs for how a patient "feels, functions or survives" in response to PAH treatment. These findings provide further support for the use of CMR as a clinically relevant clinical outcome measure and will aid trial size calculations for studies using CMR.

Plain language summaryPulmonary arterial hypertension (PAH) is a disease of the vessels of the lung that causes their narrowing and stiffening. As a result, the heart pumping blood into these diseased lung vessels has to work harder and eventually gets worn out. PAH can affect patients' ability to function in daily activities and impact their quality of life. It also reduces their life expectancy dramatically. Patients are, therefore, often monitored and undergo several investigations to adapt treatment according to their situation. These investigations include a survey of how a patient feels (the emPHasis-10 questionnaire), functions (walking test) and how well the heart is coping with the disease (MRI of the heart). Until now, it is unclear how changes on MRI of the heart reflect changes in how a patient feels and functions. Our study identified patients that had the emPHasis-10 questionnaire, walking test and MRI of the heart at both the time of PAH diagnosis and one year later. This allowed us to compare how the changes in the different tests relate to each other. And because previous research identified thresholds for important changes in the emPHasis-10 questionnaire and the walking tests, we were able to use these tests as a benchmark for changes in the MRI of the heart. Our study identified thresholds for change on heart MRI that might indicate whether a patient has improved or worsened. This finding might have implications for how patients are monitored in clinical practice and future research on PAH treatments.

Unacceptable failures: the final report of the Lancet Commission into liver disease in the UK.

This final report of the Lancet Commission into liver disease in the UK stresses the continuing increase in burden of liver disease from excess alcohol consumption and obesity, with high levels of hospital admissions which are worsening in deprived areas. Only with comprehensive food and alcohol strategies based on fiscal and regulatory measures (including a minimum unit price for alcohol, the alcohol duty escalator, and an extension of the sugar levy on food content) can the disease burden be curtailed. Following introduction of minimum unit pricing in Scotland, alcohol sales fell by 3%, with the greatest effect on heavy drinkers of low-cost alcohol products. We also discuss the major contribution of obesity and alcohol to the ten most common cancers as well as measures outlined by the departing Chief Medical Officer to combat rising levels of obesity-the highest of any country in the west. Mortality of severely ill patients with liver disease in district general hospitals is unacceptably high, indicating the need to develop a masterplan for improving hospital care. We propose a plan based around specialist hospital centres that are linked to district general hospitals by operational delivery networks. This plan has received strong backing from the British Association for Study of the Liver and British Society of Gastroenterology, but is held up at NHS England. The value of so-called day-case care bundles to reduce high hospital readmission rates with greater care in the community is described, along with examples of locally derived schemes for the early detection of disease and, in particular, schemes to allow general practitioners to refer patients directly for elastography assessment. New funding arrangements for general practitioners will be required if these proposals are to be taken up more widely around the country. Understanding of the harm to health from lifestyle causes among the general population is low, with a poor knowledge of alcohol consumption and dietary guidelines. The Lancet Commission has serious doubts about whether the initiatives described in the Prevention Green Paper, with the onus placed on the individual based on the use of information technology and the latest in behavioural science, will be effective. We call for greater coordination between official and non-official bodies that have highlighted the unacceptable disease burden from liver disease in England in order to present a single, strong voice to the higher echelons of government.

EmPHasis-10 health-related quality of life score predicts outcomes in patients with idiopathic and connective tissue disease-associated pulmonary arterial hypertension: results from a UK multicentre study.

Health-related quality of life (HRQoL) scores assess symptom burden in pulmonary arterial hypertension (PAH) but data regarding their role in prognostication and risk stratification are limited. We assessed these relationships using the emPHasis-10 HRQoL measure.1745 patients with idiopathic PAH (IPAH), drug-induced PAH (DPAH), heritable PAH (HPAH) (collectively "(I/D/H)PAH"), or connective tissue disease-associated PAH (CTD-PAH), who had completed emPHasis-10 questionnaires at one of six UK referral centres between 2014 and 2017, were identified. Correlations with exercise capacity and World Health Organization (WHO) functional class were assessed, and exploratory risk stratification thresholds were tested.Moderate correlations were seen between emPHasis-10 scores and 6-min walk distance (r=-0.546), incremental shuttle walk distance (r=-0.504) and WHO functional class (r=0.497) (all p<0.0001). Distribution of emPHasis-10 score differed significantly between each WHO functional class (all p<0.0001). On multivariate analysis, emPHasis-10 score, but not WHO functional class, was an independent predictor of mortality. In a risk stratification approach, scores of 0-16, 17-33 and 34-50 identified incident patients with 1-year mortality of 5%, 10% and 23%, respectively. Survival of patients in WHO functional class III could be further stratified using an emPHasis-10 score ≥34 (p<0.01). At follow-up, patients with improved emPHasis-10 scores had improved exercise capacity (p<0.0001) and patients who transitioned between risk groups demonstrated similar survival to patients originally in those risk groups.The emPHasis-10 score is an independent prognostic marker in patients with (I/D/H)PAH or CTD-PAH. It has utility in risk stratification in addition to currently used parameters. Improvement in emPHasis-10 score is associated with improved exercise capacity.

Identification of Cardiac Magnetic Resonance Imaging Thresholds for Risk Stratification in Pulmonary Arterial Hypertension.

Rationale: Pulmonary arterial hypertension (PAH) is a life-shortening condition. The European Society of Cardiology and European Respiratory Society and the REVEAL (North American Registry to Evaluate Early and Long-Term PAH Disease Management) risk score calculator (REVEAL 2.0) identify thresholds to predict 1-year mortality.Objectives: This study evaluates whether cardiac magnetic resonance imaging (MRI) thresholds can be identified and used to aid risk stratification and facilitate decision-making.Methods: Consecutive patients with PAH (n = 438) undergoing cardiac MRI were identified from the ASPIRE (Assessing the Spectrum of Pulmonary Hypertension Identified at a Referral Center) MRI database. Thresholds were identified from a discovery cohort and evaluated in a test cohort.Measurements and Main Results: A percentage-predicted right ventricular end-systolic volume index threshold of 227% or a left ventricular end-diastolic volume index of 58 ml/m2 identified patients at low (<5%) and high (>10%) risk of 1-year mortality. These metrics respectively identified 63% and 34% of patients as low risk. Right ventricular ejection fraction >54%, 37-54%, and <37% identified 21%, 43%, and 36% of patients at low, intermediate, and high risk, respectively, of 1-year mortality. At follow-up cardiac MRI, patients who improved to or were maintained in a low-risk group had a 1-year mortality <5%. Percentage-predicted right ventricular end-systolic volume index independently predicted outcome and, when used in conjunction with the REVEAL 2.0 risk score calculator or a modified French Pulmonary Hypertension Registry approach, improved risk stratification for 1-year mortality.Conclusions: Cardiac MRI can be used to risk stratify patients with PAH using a threshold approach. Percentage-predicted right ventricular end-systolic volume index can identify a high percentage of patients at low-risk of 1-year mortality and, when used in conjunction with current risk stratification approaches, can improve risk stratification. This study supports further evaluation of cardiac MRI in risk stratification in PAH.

Disease burden and costs from excess alcohol consumption, obesity, and viral hepatitis: fourth report of the Lancet Standing Commission on Liver Disease in the UK.

This report contains new and follow-up metric data relating to the eight main recommendations of the Lancet Standing Commission on Liver Disease in the UK, which aim to reduce the unacceptable harmful consequences of excess alcohol consumption, obesity, and viral hepatitis. For alcohol, we provide data on alcohol dependence, damage to families, and the documented increase in alcohol consumption since removal of the above-inflation alcohol duty escalator. Alcoholic liver disease will shortly overtake ischaemic heart disease with regard to years of working life lost. The rising prevalence of overweight and obesity, affecting more than 60% of adults in the UK, is leading to an increasing liver disease burden. Favourable responses by industry to the UK Government's soft drinks industry levy have been seen, but the government cannot continue to ignore the number of adults being affected by diabetes, hypertension, and liver disease. New direct-acting antiviral drugs for the treatment of chronic hepatitis C virus infection have reduced mortality and the number of patients requiring liver transplantation, but more screening campaigns are needed for identification of infected people in high-risk migrant communities, prisons, and addiction centres. Provision of care continues to be worst in regions with the greatest socioeconomic deprivation, and deficiencies exist in training programmes in hepatology for specialist registrars. Firm guidance is needed for primary care on the use of liver blood tests in detection of early disease and the need for specialist referral. This report also brings together all the evidence on costs to the National Health Service and wider society, in addition to the loss of tax revenue, with alcohol misuse in England and Wales costing £21 billion a year (possibly up to £52 billion) and obesity costing £27 billion a year (treasury estimates are as high as £46 billion). Voluntary restraints by the food and drinks industry have had little effect on disease burden, and concerted regulatory and fiscal action by the UK Government is essential if the scale of the medical problem, with an estimated 63 000 preventable deaths over the next 5 years, is to be addressed.

The importance of patient perspectives in pulmonary hypertension.

The assessment of objective measurement of cardiopulmonary status has helped us achieve better clinical outcomes for patients and develop new therapies through to the point of market access; however, patient surveys indicate that more can be done to improve holistic care and patient engagement. In this multidisciplinary review, we examine how clinical teams can acknowledge and embrace the individual patient's perspective, and thus improve the care for individual patients suffering from pulmonary hypertension by cultivating the importance and relevance of health-related quality of life in direct clinical care. At the individual level, patients should be provided with access to accredited specialist centres which provide a multidisciplinary approach where there is a culture focused on narrative medicine, quality of life, shared decision making and timely access to palliative care, and where there is participation in education. On a larger scale, we call for the development, expansion and promotion of patient associations to support patients and carers, lobby for access to best care and treatments, and provide input into the development of clinical trials and registries, focusing on the patients' perspective.

The patient experience of pulmonary hypertension: a large cross-sectional study of UK patients.

BACKGROUND: Pulmonary Hypertension Association UK (PHA-UK) is the only charity in the UK especially for people affected by pulmonary hypertension (PH). To better understand the impact of PH on patients and carers beyond clinical symptoms, the PHA-UK carried out a cross-sectional survey on the effect of PH on daily living, along with a follow-up survey assessing the financial impact of PH. METHODS: This is a descriptive cross-sectional survey of adult patients with PH in the UK. A quantitative survey of four key topics (time to diagnosis, quality of life [QoL], financial impact and specialist treatment), was made available to PHA-UK members and patients on PH therapy, with a follow-up financial impact survey sent to those responders who agreed to be contacted further. Data collection was carried out in January and February 2017 for the main survey, and November and December 2017 for the financial impact survey. RESULTS: The main survey was completed by 567 individuals, and the financial follow-up survey by 171. Mean age of responders was 69 ± 17 years with 70% female. 60% of respondents said PH had a major impact on their QoL, with 45% reporting that treatment and management improves their QoL 'a lot'. The time between first experiencing symptoms and diagnosis was ≥1 year for 48% of patients, with 40% seeing 4+ doctors before diagnosis. 63% of patients reported financial worries. Patients in part-time and full-time work reported the greatest financial burden, with a 13 and 33% fall in monthly income respectively. Patients had positive experiences of treatment in specialist centres, with 62% rating their care 'excellent', and 92% saying they preferred travelling to a specialist centre rather than seeing a local non-specialist. CONCLUSIONS: This study reports the largest UK survey exploring issues affecting patients with PH. The study shows that despite the availability of new therapies, patients are still experiencing delays prior to diagnosis, and experiencing both emotional and financial impacts from the disease. By identifying the areas patients find most important in their treatment, this research can inform future care policies and long-term management to support patients living with PH and their families.

The impact of patient choice on survival in chronic thromboembolic pulmonary hypertension.

Pulmonary endarterectomy (PEA) is the gold standard treatment for operable chronic thromboembolic pulmonary hypertension (CTEPH). However, a proportion of patients with operable disease decline surgery. There are currently no published data on this patient group. The aim of this study was to identify outcomes and prognostic factors in a large cohort of consecutive patients with CTEPH.Data were collected for consecutive, treatment-naive CTEPH patients at the Pulmonary Vascular Disease Unit of the Royal Hallamshire Hospital (Sheffield, UK) between 2001 and 2014.Of 550 CTEPH patients (mean±sd age 63±15 years, follow-up 4±3 years), 49% underwent surgery, 32% had technically operable disease and did not undergo surgery (including patient choice n=72 and unfit for surgery n=63), and 19% had inoperable disease due to disease distribution. The 5-year survival was superior in patients undergoing PEA (83%) versus technically operable disease who did not undergo surgery (53%) and inoperable due to disease distribution (59%) (p<0.001). Survival was superior in patients following PEA compared with those offered but declining surgery (55%) (p<0.001). In patients offered PEA, independent prognostic factors included mixed venous oxygen saturation, gas transfer and patient decision to proceed to surgery.Outcomes in CTEPH following PEA are excellent and superior to patients declining surgery, and strongly favour consideration of a surgical intervention in eligible patients.

Towards new recommendations to reduce the burden of alcohol-induced hypertension in the European Union.

BACKGROUND: Hazardous and harmful alcohol use and high blood pressure are central risk factors related to premature non-communicable disease (NCD) mortality worldwide. A reduction in the prevalence of both risk factors has been suggested as a route to reach the global NCD targets. This study aims to highlight that screening and interventions for hypertension and hazardous and harmful alcohol use in primary healthcare can contribute substantially to achieving the NCD targets. METHODS: A consensus conference based on systematic reviews, meta-analyses, clinical guidelines, experimental studies, and statistical modelling which had been presented and discussed in five preparatory meetings, was undertaken. Specifically, we modelled changes in blood pressure distributions and potential lives saved for the five largest European countries if screening and appropriate intervention rates in primary healthcare settings were increased. Recommendations to handle alcohol-induced hypertension in primary healthcare settings were derived at the conference, and their degree of evidence was graded. RESULTS: Screening and appropriate interventions for hazardous alcohol use and use disorders could lower blood pressure levels, but there is a lack in implementing these measures in European primary healthcare. Recommendations included (1) an increase in screening for hypertension (evidence grade: high), (2) an increase in screening and brief advice on hazardous and harmful drinking for people with newly detected hypertension by physicians, nurses, and other healthcare professionals (evidence grade: high), (3) the conduct of clinical management of less severe alcohol use disorders for incident people with hypertension in primary healthcare (evidence grade: moderate), and (4) screening for alcohol use in hypertension that is not well controlled (evidence grade: moderate). The first three measures were estimated to result in a decreased hypertension prevalence and hundreds of saved lives annually in the examined countries. CONCLUSIONS: The implementation of the outlined recommendations could contribute to reducing the burden associated with hypertension and hazardous and harmful alcohol use and thus to achievement of the NCD targets. Implementation should be conducted in controlled settings with evaluation, including, but not limited to, economic evaluation.

Long-term outcomes of domiciliary intravenous iloprost in idiopathic and connective tissue disease-associated pulmonary arterial hypertension.

BACKGROUND AND OBJECTIVE: There are few published data on the efficacy of i.v. iloprost in pulmonary arterial hypertension (PAH). We present long-term outcomes in PAH patients receiving i.v. iloprost in a large UK referral centre. METHODS: Eighty patients with idiopathic PAH (iPAH, n = 46) or PAH associated with connective tissue disease (CTD-PAH, n = 34) were identified as receiving domiciliary i.v. iloprost between January 1999 and April 2015. Baseline characteristics, doses achieved, functional class at follow-up and survival data were retrieved from hospital databases. RESULTS: Median maximum dose achieved was 4.6 ng/kg/min in the iPAH group and 5.0 ng/kg/min in CTD-PAH patients. Exercise capacity significantly improved in the first 6 months of therapy in IPAH patients. Overall 1-, 3- and 5-year survival was 78%, 64% and 52% in iPAH (P = 0.002) and 64%, 26% and 21% in CTD-PAH. Independent predictors of survival were age and exercise capacity. CONCLUSION: We report improved survival to that previously reported in iPAH patients treated with domiciliary i.v. iloprost. This may be in part related to higher administered doses. Patients with CTD-PAH had poorer survival, reinforcing the need for early transplantation referral in suitable patients.

emPHasis-10: development of a health-related quality of life measure in pulmonary hypertension.

The aim of this study was to develop a measure of the impact of pulmonary hypertension (PH) on health-related quality of life (HRQoL) as there is a need for a short, validated instrument that can be used in routine clinical practice. Interviews were conducted with 30 PH patients to derive 32 statements, which were presented as a semantic differential six-point scale (0-5), with contrasting adjectives at each end. This item list was completed by patients attending PH clinics across the UK and Ireland. Rasch analysis was applied to identify items fitting a uni-dimensional model. 226 patients (mean age 55.6±14 years; 70% female) with PH (82% had pulmonary arterial hypertension) completed the study questionnaires. 10 of the 32 items demonstrated fit to the Rasch model (Chi-squared 16; p>0.05) and generated the emPHasis-10 questionnaire. Test-retest (intraclass correlation coefficient 0.95, n=33) and internal consistency (Chronbach's α=0.9) were strong. emPHasis-10 scores correlated consistently with other relevant measures and discriminated subgroups of patients stratified by World Health Organization functional class (ANOVA F=1.73; p<0.001). The emPHasis-10 is a short questionnaire for assessing HRQoL in pulmonary arterial hypertension. It has excellent measurement properties and is sensitive to differences in relevant clinical parameters. It is freely available for clinical and academic use.

Impact of living with pulmonary hypertension: a qualitative exploration.

Little is known about the impact of living with pulmonary hypertension. This paper reports data exploring the experience of living with pulmonary hypertension. Qualitative, semistructured, one-to-one interviews were conducted in participants' homes to understand their experiences of living with pulmonary hypertension. Thematic analysis was used to identify codes and generate themes from the interview data. The identification of initial codes was conducted independently by the first author, and checked by the second. Thirty patients recruited through the pulmonary hypertension descriptions of living with pulmonary hypertension are presented under five themes that center on the invisibility of pulmonary hypertension, and its complex treatment are presented: (i) living with a hidden illness; (ii) being on a symptomology rollercoaster; (iii) expectations from treatments; (iv) treatment burden; and (v) awareness of financial burden of treatments. Key findings included daily challenges of living with a rare condition that is largely "hidden" and its related complex treatment regimes. People with pulmonary hypertension would benefit if more healthcare professionals, as well as family and friends, would validate their condition and provide them with appropriate support.

Exploratory and confirmatory factor analysis of emPHasis-10: The health-related quality-of-life measure in pulmonary hypertension.

The emPHasis-10 is a health-related quality of life (HRQoL) unidimensional measure developed specifically for adults with pulmonary hypertension. The tool has excellent psychometric properties and is well used in research and clinical settings. Its factor structure has not been examined, which may help to identity a complimentary approach to using the measure to examine patient functioning. We performed an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on a data set collected from 263 adults with PH recruited from a community setting. The EFA suggested the emPHasis-10 consists of three underlying latent variables, which based on the loading of items, were termed "fatigue" (Items 3, 4, and 5), "independence" (Items 7, 8, 9, and 10), and "breathlessness" (Items 1, 2, and 6). All factors were found to have good internal consistency. "Independence" accounted for most of the variance (29%), followed by "breathlessness" (22%) and "fatigue" (19%). The CFA looked to confirm the fit of a three-factor model. A higher-order model was found to be the best fit consisting of HRQoL as a superordinate factor, for which the association between this factor and the 10 items was mediated through the three latent factors. Further analyses were performed testing the validity of the latent variables revealing all were significantly correlated with self-reported measures of depression, anxiety, health-anxiety, and dyspnea. Our analyses support the emPHasis-10 as a measure of HRQoL, while also proposing the clinical utility of examining the three emergent factors, which could be used to glean additional insight into the respondent's functioning and inform care.

Pulmonary Hypertension: Intensification and Personalization of Combination Rx (PHoenix): A phase IV randomized trial for the evaluation of dose-response and clinical efficacy of riociguat and selexipag using implanted technologies.

Approved therapies for the treatment of patients with pulmonary arterial hypertension (PAH) mediate pulmonary vascular vasodilatation by targeting distinct biological pathways. International guidelines recommend that patients with an inadequate response to dual therapy with a phosphodiesterase type-5 inhibitor (PDE5i) and endothelin receptor antagonist (ERA), are recommended to either intensify oral therapy by adding a selective prostacyclin receptor (IP) agonist (selexipag), or switching from PDE5i to a soluble guanylate-cyclase stimulator (sGCS; riociguat). The clinical equipoise between these therapeutic choices provides the opportunity for evaluation of individualized therapeutic effects. Traditionally, invasive/hospital-based investigations are required to comprehensively assess disease severity and demonstrate treatment benefits. Regulatory-approved, minimally invasive monitors enable equivalent measurements to be obtained while patients are at home. In this 2 × 2 randomized crossover trial, patients with PAH established on guideline-recommended dual therapy and implanted with CardioMEMS™ (a wireless pulmonary artery sensor) and ConfirmRx™ (an insertable cardiac rhythm monitor), will receive ERA + sGCS, or PDEi + ERA + IP agonist. The study will evaluate clinical efficacy via established clinical investigations and remote monitoring technologies, with remote data relayed through regulatory-approved online clinical portals. The primary aim will be the change in right ventricular systolic volume measured by magnetic resonance imaging (MRI) from baseline to maximal tolerated dose with each therapy. Using data from MRI and other outcomes, including hemodynamics, physical activity, physiological measurements, quality of life, and side effect reporting, we will determine whether remote technology facilitates early evaluation of clinical efficacy, and investigate intra-patient efficacy of the two treatment approaches.

Pulmonary hypertension in COPD: results from the ASPIRE registry.

The phenotype and outcome of severe pulmonary hypertension in chronic obstructive pulmonary disease (COPD) is described in small numbers, and predictors of survival are unknown. Data was retrieved for 101 consecutive, treatment-naïve cases of pulmonary hypertension in COPD. Mean ± SD follow-up was 2.3 ± 1.9 years. 59 patients with COPD and severe pulmonary hypertension, defined by catheter mean pulmonary artery pressure ≥40 mmHg, had significantly lower carbon monoxide diffusion, less severe airflow obstruction but not significantly different emphysema scores on computed tomography compared to 42 patients with mild-moderate pulmonary hypertension. 1- and 3-year survival for severe pulmonary hypertension, at 70% and 33%, respectively, was inferior to 83% and 55%, respectively, for mild-moderate pulmonary hypertension. Mixed venous oxygen saturation, carbon monoxide diffusion, World Health Organization functional class and age, but not severity of airflow obstruction, were independent predictors of outcome. Compassionate treatment with targeted therapies in 43 patients with severe pulmonary hypertension was not associated with a survival benefit, although improvement in functional class and/or fall in pulmonary vascular resistance >20% following treatment identified patients with improved survival. Standard prognostic markers in COPD have limited value in patients with pulmonary hypertension. This study identifies variables that predict outcome in this phenotype. Despite poor prognosis, our data suggest that further evaluation of targeted therapies is warranted.

Patient information that promotes healt literacy.

Health literacy is the ability to make informed health decisions in everyday life. For many patients and carers, decision-making is made more difficult by the fact that high-quality information is unavailable to them. The Pulmonary Hypertension Association has created patient materials that promote health literacy to help patients and their families make decisions that are well informed.

A systematic review of psychological interventions in adults with pulmonary hypertension: Is the evidence-base disproportionate to the problem?

INTRODUCTION: Our understanding of the psychological impact of living with pulmonary hypertension (PH) is growing, particularly for how anxiety and depression present in this group. There is evidence for the use of psychological interventions in other chronic lung conditions; however, trials focusing on adults with PH have yet to be subject to a systematic review. METHODS: We systematically searched four databases for evidence examining the effectiveness of psychological interventions for adults with PH. A narrative approach has been used to present findings. RESULTS: Overall, 186 unique articles were identified of which four were suitable. Data was gathered from 143 individuals. Cognitive behavioural therapy (CBT), metacognitive therapy (MCT) or counselling were investigated. All three studies reported a significant reduction in anxiety and depression, and some secondary outcomes were also associated with change. DISCUSSION: The evidence supporting the use of psychological therapies for adults with PH is promising, although limited. There is an urgent need for more research in this area to better understand how we can support this clinical group.

Can self-compassion help us better understand the impact of pulmonary hypertension on those with the condition and their carers? A cross-sectional analysis.

Pulmonary hypertension (PH) can have a multifaced impact both on the affected individual and close family members. However there are relatively few studies that have sought to identify potential protective factors. Individual differences in ability to be self-compassionate are known to be implicated in adjustment in other long-term conditions and are now featuring in the provision of care for a number of conditions. This is a cross-sectional study that investigated the relationship between self-compassion, demographic, PH-related information, and measures of psychosocial functioning in adults with PH (n = 65) and caregivers (n = 29). Individuals with PH and caregivers of someone with PH completed self-report measures on demographic and clinical factors, anxiety, depression, self-compassion, and in those with PH, health-related quality of life, and in carers, caregiver burden. Data were analyzed using hierarchical regression analyses. Surprisingly, participants with PH and caregivers did not significantly differ on rates of depression (p = 0.19) or anxiety (p = 0.57) with both scoring relatively high. Components of self-compassion were associated with psychological functioning in both individuals and caregivers. Greater self-compassion was associated with fewer symptoms of anxiety and depression, and greater health-related quality of life in individuals with PH and lower burden in caregivers. More specifically, multiple regression analyses revealed after controlling for age, gender, and duration of PH, self-compassion was a significant predictor of anxiety and depression in people with PH, and of anxiety and caregiver burden in carers. These findings add to the evidence base indicating that there can be a range of burdens experienced by both people living with PH and their wider families. Further, this study uniquely suggests that psychological and supportive interventions that seek to build self-compassion may be useful to develop and test in this clinical group.
