Interest of TAPSE/sPAP ratio for noninvasive pulmonary arterial hypertension risk assessment. J Heart Lung Transplant 2022; 41:1761-1772. [PMID: 36202691 DOI: 10.1016/j.healun.2022.09.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 08/24/2022] [Accepted: 09/08/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Although ventriculoarterial coupling is associated with better survival in pulmonary arterial hypertension (PAH), existing PAH risk assessment method has not considered echocardiographic criteria of right ventricular to pulmonary artery coupling. We aimed to test the prognostic value of the echocardiographic tricuspid annular plane systolic excursion/systolic pulmonary artery pressure (TAPSE/sPAP) ratio for noninvasive PAH risk assessment. METHODS We retrospectively studied a cohort of 659 incident PAH patients from 4 independent French PH centers (training cohort: n = 306, validation cohort n = 353) who underwent follow-up TAPSE/sPAP measurement in addition to previously validated noninvasive risk stratification variables. The primary composite outcome was 3-year all-cause mortality or lung transplantation from re-evaluation. RESULTS Mean age was 55 ± 17 years-old with a majority of female (66%). The three main PAH causes were connective tissue disease (26%), idiopathic (24%) and porto-pulmonary (19%). The primary composite outcome occurred in 71 (23%) patients. Multivariable Cox regression analysis retained 3 noninvasive low-risk criteria as associated with the primary composite outcome: NYHA I-II (p = 0.001), NTproBNP <300 ng/L or BNP <50 ng/L (p = 0.004), and TAPSE/sPAP >0.33 mm/mmHg (p = 0.004). The more the low-risk criteria achieved at follow-up, the better the event-free survival both in the training and validation cohort (log-rank p < 0.001). In the training cohort, the c-index for these 3 criteria, for COMPERA 2.0 and for the noninvasive French Pulmonary Hypertension Network method were 0.75, 95%CI(0.70-0.82), 0.72 95%CI(0.66-0.75), 0.71 95%CI(0.62-0.73), respectively. CONCLUSION The 3 following dichotomized low-risk criteria: TAPSE/sPAP >0.33 mm/mmHg, NYHA I-II and NTproBNP <300 ng/L or BNP <50 ng/L allow to identify low-risk PAH patients at follow-up.

Abstract
Abstract
Background
While pulmonary vasodilation therapy improves right ventricular (RV) function in pulmonary arterial hypertension (PAH), data regarding left ventricular (LV) function remain sparse.
Purpose
We aimed to investigate whether PAH therapy improve LV function in PAH patients.
Methods
Between 2002 and 2020, all incident PAH patients from one PH referral centers were included, treated and followed-up according to current ESC/ERS guidelines. All patients had comprehensive echocardiography both investigating right and left ventricular function before and after 1-year of vasodilation therapy. In addition to RV echocardiographic evaluation, we focused on LV ejection fraction from Modified Simpson method, LV diameters by M-mode, transmitral pulsed-wave E/A ratio, Flow to tissue Doppler imaging E/e' ratio, and left atrial size.
Results
126 patients were included (63% female, 57±17 yo), mainly from connectivite tissue associated and idiopathic PAH (24% and 28% respectively) causes. Compared to baseline, 1-year NYHA functional class (p<0.01), NTproBNP plasma level (p<0.001), invasive mean pulmonary arterial pressure (p<0.01) and cardiac index (p<0.01) significantly improved. While LV ejection fraction (p=0.68), LV end-diastolic diameter (p=0.11) as well as LA area and volume (p=0.09) were not significantly enhanced under vasodilation therapy, LV diastolic function, assessed by mitral E wave (p<0.01), tissue doppler imaging mitral e' wave (p=0.04), and E/A ratio (p=0.045) were significantly improved at 1-year. There was a significant correlation between LV end-diastolic diameter (p<0.001) and RV end-diastolic area (p<0.001) owing to the normalization of right- to left ventricular interdependence, as well as between mitral E wave and TAPSE (p=0.045).
Conclusion
By improving RV function, PAH vasodilation therapy enhances LV size and diastolic function and normalizes the biventricular interdependence.

Abstract
Abstract
Background
Although preserved right ventricular (RV) function is consistently associated with better survival in pulmonary arterial hypertension (PAH), the French risk assessment method has not yet considered echocardiographic criteria of RV function.
Purpose
In the present study, we tested the value of tricuspid annular plane systolic excursion (TAPSE) measured by echocardiography for non-invasive PAH risk assessment.
Methods
We retrospectively studied a cohort of 306 incident PAH patients treated in two French expert centers who underwent follow-up TAPSE measurement from echocardiographic apical 4-chamber view in addition to previously validated invasive and non-invasive risk stratification variables. The primary composite outcome was 3-year lung transplantation free survival after follow-up assessment.
Results
At re-evaluation, 66% of patients were in NYHA functional class I-II and mean pulmonary arterial pressure, cardiac index, N-Terminal pro brain natriuretic peptide (NTproBNP), and 6-minute walk distance (6MWD) were 40±16 mmHg, 3.5±1.1 L/min/m2, 270 [interquartile range (IQR) 896] ng/L and 401 (IQR 213) meters, respectively. The primary outcome occurred in 58 (19%) patients. In multivariable Cox regression analysis, NYHA functional class I-II (p=0.02), NTproBNP <300 ng/L or BNP <50 ng/L (p=0.02), 6MWD >440m (p=0.049) and TAPSE≥17 mm (p=0.02) were associated with lung transplantation free survival. TAPSE provided similar information over 6MWD when both were used alternatively to stratify PAH patients at low risk (log-rank<0.001); Harrell's c-index 0.73.
Conclusion
Three dichotomized low-risk criteria (TAPSE, 6MWD and NTproBNP or BNP plasma levels) allow non-invasive risk assessment in PAH.

Abstract
Abstract
Background
While in heart failure with reduced ejection fraction, left ventricular reverse remodeling assessed by transthoracic echocardiography (TTE) is associated with better prognosis, right ventricular reverse remodeling (RVRR) was less investigated in pulmonary arterial hypertension (PAH)
Purpose
We aimed to investigate whether RVVR assessed by echocardiography could help to stratify PAH patient's prognosis.
Methods
Between 2002 and 2019, all consecutive PAH patients were included, treated and followed in a single PAH center in accordance with the current ESC/ERS guidelines. In addition to regular risk stratification parameters, we measured several echocardiographic RV systolic function and size parameters, including tricuspid annular plane systolic excursion (TAPSE, mm) or RV-end diastolic area (cm2) from apical-4 chamber view both at baseline, 1-year of follow-up as well as their change. Primary composite outcome was three-year transplant-free survival and death from all cause from the 1-year evaluation. Conditional inference trees were used to determine which TTE parameters and cutoffs values were associated with primary outcome from hierarchy of multiple covariates in multivariable Cox regression analysis. Kaplan-Meier curves were then drawn and compared with log-rank test.
Results
126 incident PAH patients were included (63% female, mean age 59±18 yo), mainly due to connectivite-tissue disease and idiopathic PAH (26% and 22% respectively). At baseline, mean pulmonary arterial pressure was 42 (33, 52) mmHg. At 1-y follow-up under pulmonary vasodilation therapy, NYHA (p<0.01), NTproBNP (p<0.01), mean pulmonary arterial pressure (p<0.01) and cardiac index (p<0.01) were significantly improved compared to baseline. Conditional inference trees showed that 1-year TAPSE gain >1 mm and 1-year RV end-diastolic area decreased >2 cm2 were associated with 3-year transplant-free survival in multivariable Cox regression analysis (HR=0.23, 95% CI [0.08–0.61] p=0,0035, HR=0.34, 95% CI [0.12–0.94], p=0.038). Simple score from 0 (absence of RVRR), 1 (partial RVRR) and 2 (complete RVRR), describing the number of TTE parameters reach at 1-year was then investigated. Patients with complete RVRR depicted better transplant-free survival than partial or absence of RVRR, log-rank p<0.001 (figure).
Conclusion
Complete reverse remodeling from right ventricular size and function could represent a new goal-oriented treatment strategy in PAH patients.

Abstract
INTRODUCTION Although home non-invasive ventilation (NIV) is increasingly used to manage patients with chronic ventilatory failure, there are limited data on the long-term outcome of these patients. Our aim was to report on home NIV populations and the long-term outcome from two European centres. METHODS Cohort analysis including all patients established on home NIV from two European centres between 2008 and 2014. RESULTS Home NIV was initiated in 1746 patients to treat chronic ventilatory failure caused by (1) obesity hypoventilation syndrome±obstructive sleep apnoea (OHS±OSA) (29.5%); (2) neuromuscular disease (NMD) (22.7%); and (3) obstructive airway diseases (OAD) (19.1%). Overall cohort median survival following NIV initiation was 6.6 years. Median survival varied by underlying aetiology of respiratory failure: rapidly progressive NMD 1.1 years, OAD 2.7 years, OHS±OSA >7 years and slowly progressive NMD >7 years. Multivariate analysis demonstrated higher mortality in patients with rapidly progressive NMD (HR 4.78, 95% CI 3.38 to 6.75), COPD (HR 2.25, 95% CI 1.64 to 3.10), age >60 years at initiation of home NIV (HR 2.41, 95% CI 1.92 to 3.02) and NIV initiation following an acute admission (HR 1.38, 95% CI 1.13 to 1.68). Factors associated with lower mortality were NIV adherence >4 hours per day (HR 0.64, 95% CI 0.51 to 0.79), OSA (HR 0.51, 95% CI 0.31 to 0.84) and female gender (HR 0.79, 95% CI 0.65 to 0.96). CONCLUSION The mortality rate following initiation of home NIV is high but varies significantly according to underlying aetiology of respiratory failure. In patients with chronic respiratory failure, initiation of home NIV following an acute admission and low levels of NIV adherence are poor prognostic features and may be amenable to intervention.

Abstract
BACKGROUND Pulmonary hypertension (PH) is a heterogeneous, severe and progressive disease with an impact on quality of life and life-expectancy despite specific therapies. AIMS (i) to compare prognosis significance of each PH subgroup in a cohort from a referral center, (ii) to identify phenotypically distinct high-risk PH patient using machine learning. METHODS Patients with PH were included from 2002 to 2019 and routinely followed-up. We collected clinical, laboratory, imaging and hemodynamic variables. Four-year survival rate of each subgroups was then compared. Next, phenotypic domains were imputed with 5 eigenvectors for missing values and filtered if the Pearson correlation coefficient was>0.6. Thereafter, agglomerative hierarchical clustering was used for grouping phenotypic variables and patients: a heat map was generated and participants were separated using Penalized Model-Based Clustering. P<0.05 was considered significant. RESULTS 328 patients were prospectively included (mean age 63±18 yo, 46% male). PH secondary to left heart disease (PH-LHD) and lung disease (PH-LD) had a significantly increased mortality compared to pulmonary arterial hypertension (PAH) patients: HR=2.43, 95%CI=(1.24-4.73) and 2.95, 95%CI=(1.43-6.07) respectively. 25 phenotypic domains were pinpointed and 3 phenogroups identified. Phenogroup 3 had a significantly increased mortality (log-rank P=0.046) compared to the others and was remarkable for predominant pulmonary disease in older male, accumulating cardiovascular risk factors, and simultaneous three major comorbidities: coronary artery disease, chronic kidney disease and interstitial lung disease. CONCLUSION PH-LHD and PH-LD has 2-fold and 3-fold increase in mortality, respectively compared with PAH. PH patients with simultaneous kidney-cardiac-pulmonary comorbidities were identified as having high-risk of mortality. Specific targeted therapy in this phenogroup should be prospectively evaluated.

Abstract
Purpose There are many barriers to pulmonary rehabilitation, including a limited access to evaluation centers. To cope with these difficulties, field tests are often used to prescribe endurance training. As field tests are related to muscle strength, they could also be used to prescribe strength training and increase the access to pulmonary rehabilitation in rural area. However, their validity for this purpose has never been studied. Patients and methods The relationship between the 6-minute stepper test (6MST), 6-minute walk test, maximal workload achieved during cardiopulmonary exercise testing (Wpeak), and one repetition maximum (1RM) was assessed in 35 patients with COPD through a retrospective chart review to derive predictive equation of the 1RM from these tests. The effectiveness of these equations to prescribe strength training at 70% of the 1RM was assessed in an independent cross-validation group of 34 patients with COPD. Results There was a moderate relationship between the 6MST, Wpeak and the 1RM (r=0.44 and r=0.41, respectively, both P≤0.01). Whatever the test, the prescription of strength training using the estimated 1RM compared with the measured 1RM resulted in a mean absolute difference and a mean bias of about 30 kg. Conclusion The use of the 6MST and Wpeak for the prescription of strength training would result in a clinically not acceptable error. Therefore, they should not be used as a substitute for the 1RM to prescribe strength training.

Abstract
QUESTIONS Can people referred to pulmonary rehabilitation easily learn to use a system for remote transmission of oximetry data? Do they consider remote transmission of oximetry data to be satisfactory? Are the transmitted data valid compared with locally stored data? DESIGN Multicentre, prospective, observational study. PARTICIPANTS One hundred and five adults with chronic respiratory disease who were referred to pulmonary rehabilitation. INTERVENTION At an initial session, participants were taught to record and transmit their oximetry data to a remote server. At subsequent testing session(s), participants were requested to independently activate and use the oximetry monitoring system for a period of exercise on a cycle ergometer, until autonomy with the system was demonstrated. A subgroup of five participants undertook five 45-minute training sessions to generate a dataset to assess whether the transmitted data were valid compared with the locally stored data. OUTCOME MEASURES Outcome measures included the number of sessions needed to become autonomous, participant satisfaction with the system, and measures of the validity of the transmitted data. RESULTS Participants became autonomous quickly: 86% at the first testing session and 100% within three testing sessions. At least 98% of participants agreed that the system was easy to use and they would be willing to use it throughout pulmonary rehabilitation. The system transmitted usable data from 98% (95% CI 96 to 100) of sessions and introduced minimal artefact. Mean absolute differences were 0.365 beats/minute for heart rate and 0.133% for oxyhaemoglobin saturation. For heart rate, exact agreement was 72% (SD 9) and similar agreement (within 3 beats/minute) was 99% (SD 1). For oxyhaemoglobin saturation, exact agreement was 87% (SD 3) and similar agreement (within 3%) was 100% (SD 0). CONCLUSION The telemonitoring system used in this study was sufficiently valid and acceptable for use in at-home pulmonary rehabilitation by people with chronic respiratory disease. STUDY REGISTRATION ClinicalTrials.gov NCT03295474 and NCT03004716 (subgroup study).

Abstract
Studies reporting the effects of modern strategies with pulmonary arterial hypertension (PAH)-targeted therapies in sarcoidosis-associated pulmonary hypertension (S-APH) are limited.Clinical and haemodynamic data from newly diagnosed patients with severe S-APH (mean pulmonary artery pressure (mPAP) >35 mmHg or mPAP 25–35 mmHg with cardiac index <2.5 L·min−1·m−2) were collected from the French Pulmonary Hypertension Registry between 2004 and 2015.Data from 126 patients with severe S-APH were analysed (mean±sd age 57.5±11.6 years, 74% radiological stage IV). 97 patients (77%) received PAH-targeted therapy and immunosuppressive therapy was initiated or escalated in 33 patients at the time of pulmonary hypertension diagnosis. Four months after PAH-targeted therapy initiation, mean±sd pulmonary vascular resistance decreased from 9.7±4.4 to 6.9±3.0 Wood units (p<0.001), without significant improvement in exercise capacity. Among the 11 patients treated only with immunosuppressive therapy, a haemodynamic improvement was observed in four patients, including two with compressive lymph nodes. After a median follow-up of 28 months, 39 patients needed PAH-targeted therapy escalation, nine underwent lung transplantation and 42 had died. Survival at 1, 3 and 5 years was 93%, 74% and 55%, respectively.PAH-targeted therapy improved short-term pulmonary haemodynamics in severe S-APH without change in exercise capacity. Immunosuppressive therapy improved haemodynamics in selected patients. Pulmonary hypertension in sarcoidosis remains associated with a poor prognosis.

Abstract
Imaging studies have shown that pulmonary hypertension (PH) is associated with inhomogenous right ventricular (RV) regional contraction, or dyssynchrony, and that this is of prognostic relevance. This study aimed at the identification and functional significance of RV dyssynchrony in borderline PH defined by a mean pulmonary artery pressure between (mPAP) 20 and 25 mmHg. RV dyssynchrony was measured by 2-dimensional speckle tracking echocardiography in 17 patients with pulmonary arterial hypertension (PAH), 13 patients with borderline PH and 14 controls. Dyssynchrony was defined as the R-R interval-corrected standard deviation of the times to peak-systolic strain for the basal and medium segments of the RV. All the PH patients underwent a right heart catheterization. RV dyssynchrony amounted to 69 ± 34 ms in PAH, 47 ± 23 ms in borderline PH and 8 ± 6 ms in controls, all different from each other (p < 0.05). RV dyssynchrony in borderline PH was the only parameter of RV systolic dysfunction in 11 of 13 (85%) of the patients. RV dyssynchrony was accompanied by postsystolic shortening and correlated to RV fractional area change, not to mPAP or pulmonary vascular resistance. RV dyssynchrony occurs in borderline PH and may reflect early RV-arterial uncoupling.

Abstract
Background Arterial punctures for assessment of arterial blood-gases can be a painful procedure. Lidocaine can be used to reduce pain prior to needle insertion but it is not a widely accepted practice. The purpose of this study was to determine whether a large size needle induces more pain compared to a smaller size needle for radial arterial puncture and to assess the anxiety associated with radial arterial punctures. Methods We conducted a prospective, double-blind, randomized, controlled, monocentric study including all outpatients who had a planned assessment of arterial blood gas analysis. Patients were randomized to have the arterial puncture performed with a 23 or a 25 G needle. The main judgement criteria was pain during arterial puncture. Visual analogue scale for pain (VAS-P) and visual analogue scale for anxiety (VAS-A) were used to assess pain and anxiety during radial arterial puncture. Results Two hundred consecutive patients were randomized. The 25 G needle was as painful as the 23 G needle (6.63 mm [0–19 mm] vs. 5.21 mm [0–18.49 mm], respectively, p = 0.527). Time for arterial puncture was longer with the 25 G needle than with the 23 G needle (42 s [35–55 s] vs. 33 s [24.5–35 s], respectively, p = 0.002). There was a correlation between the level of anxiety prior to the arterial puncture and the pain experienced by the patients (p: 0.369, p<0.0001). There was a correlation between the pain experienced by patients and the anxiety experienced in anticipation of another arterial puncture (p: 0.5124, p<0.0001). Conclusions The use of 23 G needle allows quicker arterial sampling and is not associated with increased pain and symptoms. Anxiety was correlated with the pain experienced by patients during arterial punctures. Trial Registration Clinicaltrials.gov: NCT02320916

Abstract
AIM There are few data showing how pulmonary rehabilitation (PR) for COPD patients carried out at home impacts on health-related quality of life (HRQL). The aim of this study was to determine if PR conducted at home improves quality of life. METHODS We compared the results of home-based PR versus PR performed in an outpatient center. The outcomes were the HRQL measured by the Saint-George's Hospital questionnaire and the 6-minute walk test distance (6MWT). Fifty-six COPD patients were included for PR either at home (n=27) or in the outpatient center (n=29) depending on distance from the center and patients preference. The two groups were similar for sex, age, BMI, lung function, and initial peak oxygen uptake. RESULTS 6MWT showed a similar non-significant improvement in both groups after PR (+12±46m in home-based PR,+13±34m in outpatient center). HRQL was significantly improved in the home-based group in 2 domains : "Activity" (-8.6±6.4 vs -0.7±17.7, P<0.05), "Impact" (-8.4±6.5 vs 1.6±11.7, P<0.001) and total score (-8.2±4.0 vs 0.0±8.8, P<0.001). CONCLUSION Pulmonary rehabilitation at home is associated with improvements in health-related quality of life, and thus can be considered where availability of treatment in specialized centers is limited.

Abstract
The predictive factors for long-term dependency (LTD) on noninvasive ventilation (NIV) immediately after acute hypercapnic respiratory failure (AHRF) have not been identified. The present authors studied 42 patients with chronic obstructive pulmonary disease (COPD) and 58 non-COPD patients successfully treated by NIV for an AHRF episode. Parameters at stable state, at admission for AHRF and during a 1-yr follow-up were compared in patients with or without LTD-NIV at discharge. The incidence of LTD-NIV was 39% in non-COPD patients and 19% in COPD patients. Based on multivariate analysis with stepwise logistic regression, lower baseline pH values and noninfectious causes of AHRF were independently associated with LTD-NIV. Mutually adjusted odds ratios were found to be 1.316 (95% confidence interval (CI) = 1.127-1.536) for a 0.01 decrease of baseline pH value and 5.1 (95% CI = 1.8-14.0) for a noninfectious cause of AHRF. Outcome after 1 yr was poor in COPD patients. Long-term dependency on noninvasive ventilation is not an uncommon situation after resolution of an acute hypercapnic respiratory failure episode, especially in patients with non-chronic obstructive pulmonary disease causes of respiratory failure. The present study raises the need for prospective validation of a weaning protocol in patients managed by noninvasive ventilation for an acute hypercapnic respiratory failure episode.

Abstract
BACKGROUND Cryptococcosis and alternariosis are rare opportunistic infections often observed in immunocompromised patients. Because Cryptococcus and Alternaria are ubiquitous fungi found in soil, the presence of fungi in the dermis has to be observed on histological examination to confirm a real cutaneous, invasive, infection. PATIENT We report the first case of concomitant cutaneous cryptococcosis and cutaneous alternariosis, in an immunocompromised patient treated for a metastatic thymoma. CONCLUSION This observation underlines the fact that the possible co-existence of several rare infections in immunocompromised patients should take into consideration pathogen identification in order to adapt the therapy to individual patient requirements.
