• Metabolomics of Right Ventricular Function in Pulmonary Hypertension

  Circulation Research · 2026-04-15 · 1 citations

  article

  BACKGROUND: The metabolic mechanisms underlying right ventricular (RV) dysfunction are poorly understood, particularly outside of group 1 pulmonary hypertension (PH). We aimed to identify metabolites and pathways associated with RV systolic function and explored whether associations differed by pulmonary vascular resistance, PH group 1 status, and sex. METHODS: We analyzed data from the multicenter PVDOMICS (Pulmonary Vascular Disease Phenomics) cohort. RV systolic function metrics included fractional area change (echo), global longitudinal strain (echo), and ejection fraction (cardiac magnetic resonance). We used linear regression adjusted for age, sex, body mass index, and PH group to assess associations between metabolites and RV function. Pathway enrichment analyses were used to identify pathways significantly associated with RV function. Interaction terms were assessed to determine whether metabolite associations were modified by pulmonary vascular resistance, group 1 PH status, or sex. Least absolute shrinkage and selection operator regression was used to develop metabolite-based scores for RV function, and prognostic performance was assessed. RESULTS: There were 979 participants with plasma metabolomics and RV function data. Linear regression identified 170 metabolites that were significantly associated with all 3 RV metrics. Androgenic steroid, gamma-glutamyl amino acid, polyamine, vitamin A, fatty acid, and sterol pathways are most strongly associated with RV systolic function. Two metabolites interacted with group 1 PH status, and 6 interacted with pulmonary vascular resistance. Four androgenic steroids are associated more strongly with RV systolic function in women compared with men. Metabolite-based scores were prognostically equivalent to RV systolic function metrics and less accurate than REVEAL Lite 2 scores. CONCLUSIONS: We provide a blueprint of metabolites and metabolic pathways associated with RV systolic function across the spectrum of PH. Novel links to vitamin A and glutathione metabolites were observed. We detected few metabolites that associated with RV systolic function differentially by group 1 PH status or degree of pulmonary vascular resistance elevation. Androgenic steroids may associate more strongly with RV systolic function in women compared with men.

• Dysregulated Tricarboxylic Acid Cycle Metabolism Is Associated With Right Ventricular Maladaptation in Pulmonary Vascular Disease

  Journal of the American Heart Association · 2025-05-22 · 7 citations

  articleOpen access

  BACKGROUND: Right ventricular (RV) maladaptation to elevated pulmonary afterload is the primary determinant of outcomes in pulmonary artery (PA) hypertension; however, the pathobiological mechanisms underlying RV decompensation remain poorly understood. METHODS: We performed global untargeted metabolomics on plasma from 55 patients who underwent gold-standard RV-PA coupling measurements using multibeat pressure volume loop assessment in a single-center cohort and from 1027 patients with coupling surrogate measurements in a larger multicenter cohort, the PVDOMICS (Pulmonary Vascular Disease Phenomics) study. Age and sex-adjusted linear regression was performed to identify associations between metabolites and coupling metrics. Additionally, we performed a metabolic flux analysis using gene expression data from RV tissue in an independent cohort of 32 patients. Partial least squares-discriminant analysis was used to identify metabolites and reactions characteristic of the decompensated RV. RESULTS: RV-PA coupling was negatively associated with tricarboxylic acid (TCA) cycle intermediate levels. Specifically, plasma α-ketoglutarate and fumarate were significantly associated with all coupling metrics in both cohorts. Metabolic flux analysis indicated that decompensated RVs exhibited aberrant TCA cycle activity, including reduced acetyl coenzyme A entry and increased lactate elimination, suggesting a shift from the TCA cycle toward glycolysis at the RV tissue level. CONCLUSIONS: We identify an association between circulating TCA cycle intermediate levels and RV-PA uncoupling in 2 independent cohorts, and dysregulated TCA cycle metabolism in decompensated PA hypertension RVs, suggesting that aberrant TCA cycle metabolism could represent a hallmark of RV maladaptation in PA hypertension. Further study of this pathway is warranted to develop novel biomarkers of RV function or RV-targeted therapies.

• Assessing the Utility of Provocative Maneuvers During Right Heart Catheterization in Pulmonary Venous Hypertension

  American Journal of Respiratory and Critical Care Medicine · 2025-05-01

  article

  Abstract Rationale: Although guidelines recommend the use of provocative testing to diagnose pulmonary venous hypertension (PVH) that is unapparent at normal resting right heart catheterization (RHC), the incremental value of provocative testing is unknown. We aim to evaluate the incremental diagnostic capability of inhaled nitric oxide (iNO), fluid challenge (FC) or invasive cardiopulmonary exercise testing (iCPET) to unmask PVH using previously defined hemodynamic cutoffs. Methods: We included subjects from the NHLBI-funded Pulmonary Vascular Disease Phenomics (PVDOMICS) study. Our analysis included patients with World Symposium on Pulmonary Hypertension (WSPH) Group 2 disease (G2PH) and G2PH comparators (WSPH Group 2 phenotype without a diagnosis of PH) as determined by the PI or adjudication panel. We then applied a protocol-driven provocative approach based on the feasibility of modalities available in most catheterization labs. Using a pulmonary capillary wedge pressure (PCWP) cutoff of >15, frequencies were identified for subjects based on resting PCWP and with iNO. Frequencies were also identified for: those who received FC with a PCWP cutoff of ≥18 or those who received iCPET with PCWP cutoff of >20 (upright) or >25 (supine). Results: There were 419 subjects identified with WSPH Group 2 disease (Figure). Roughly half were found to have a PCWP >15 during resting RHC (N = 207). Of the remaining subjects with a resting PCWP ≤15 (N = 150), 42 subjects were found to have a PCWP >15 with iNO administration (40.0%). Of the remaining 63 subjects with PCWP ≤15 following iNO administration, nearly half (N = 26, 48.0%) demonstrated a PCWP ≥18 following FC while 8 subjects (14.8%) demonstrated an elevated PCWP following iCPET. Conclusions: There is a high proportion of G2PH patients (∼35%) who appear hemodynamically similar to precapillary PH at rest. Inhaled nitric oxide vasodilatory challenge unmasks G2PH in many patients. In situations where iNO does not disclose the G2PH phenotype, provocation with FC or iCPET can be useful as a supplementary provocative maneuver. Future directions will focus on agnostically assessing the utility of provocation based on grouping subjects by resting hemodynamics as well as assessing the use of provocation in other forms of PH.

• Prevalence and Clinical Implications of Excess Adiposity in Group 1 Pulmonary Hypertension

  Circulation Heart Failure · 2025-12-03

  article

  BACKGROUND: Although obesity and insulin resistance (IR) are established risk factors for left heart dysfunction, their clinical impact in group 1 pulmonary hypertension (PH) remains unclear. We sought to determine the impact of excess adiposity versus IR on biventricular hemodynamic and functional reserve in group 1 PH. METHODS: Homeostasis model of insulin resistance and adiposity indices (body mass index [BMI], fat mass, waist circumference) were measured among group 1 patients with PH recruited to PVDOMICS (Redefining Pulmonary Hypertension Through Pulmonary Vascular Disease Phenomics). Functional capacity, and dynamic pulmonary capillary wedge pressure (PCWP) and right atrial pressure responses were compared stratified by obesity (BMI≥30 kg/m 2 ) and IR status (HOMA-IR≥2.6) using repeated-measure mixed models. RESULTS: Among patients with group 1 PH (n=418), 158 (38%) had BMI≥30 kg/m 2 (94 [60%] of whom had IR), and 260 (62%) had BMI<30 kg/m 2 (74 [28%] of whom had IR). Among those with waist circumference measurement (n=375), 287 (77%) had excess adiposity by elevated waist/height ratio, with 214 (57%) having elevated waist circumference. Patients with obesity had worse quality of life, exercise capacity and left heart remodeling, along with higher resting/dynamic PCWP, right atrial pressure and cardiac output ( P <0.0001 for all). Higher PCWP response with obesity persisted after adjusting for IR (IR-adjusted PCWP+2.5 mm Hg [95% CI, +1.4 to +3.6]; P <0.0001). All adiposity indices were consistently associated with PCWP response, but IR was not. Similar associations were observed between adiposity indices with higher right atrial pressure and cardiac output. Greater visceral adiposity as measured by body shape index (hazard ratio, 2.01 [95% CI, 1.16–3.47]; P =0.01) or weight-adjusted waist index (hazard ratio, 1.64 [95% CI, 1.10–2.46]; P =0.01) was associated with worse survival. CONCLUSIONS: Excess adiposity is common in group 1 PH, occurring in 4 out of 5 patients by the more sensitive waist/height ratio, in contrast to only 2 out of 5 patients having obesity by traditional BMI criteria. Excess adiposity is associated with higher biventricular filling pressures, cardiac output demand, worse functional status and reduced survival. These data support trials of adipose-reducing therapies in patients with group 1 PH and excess adiposity.

• Health disparities and treatment approaches in portopulmonary hypertension and idiopathic pulmonary arterial hypertension: an analysis of the Pulmonary Hypertension Association Registry

  UNC Libraries · 2025-04-17

  articleOpen access

  Compared to idiopathic pulmonary arterial hypertension (IPAH), patients with portopulmonary hypertension (POPH) have worse survival. Health disparities may contribute to these differences but have not been studied. We sought to compare socioeconomic factors in patients with POPH and IPAH and to determine whether socioeconomic status and/or POPH diagnosis were associated with treatment and health-care utilization. We performed a cross-sectional study of adults enrolled in the Pulmonary Hypertension Association Registry. Patients with IPAH (n = 344) and POPH (n = 57) were compared. Compared with IPAH, patients with POPH were less likely to be college graduates (19.6% vs. 34.9%, p = 0.02) and more likely to be unemployed (54.7% vs. 30.5%, p < 0.001) and have an annual household income below poverty level (45.7% vs. 19.0%, p < 0.001). Patients with POPH had similar functional class, quality of life, 6-min walk distance, and mean pulmonary arterial pressure with a higher cardiac index. Compared with IPAH, patients with POPH were less likely to receive combination therapy (46.4% vs. 62.2%, p = 0.03) and endothelin receptor antagonists (28.6% vs. 55.1%, p < 0.001) at enrollment with similar treatment at follow-up. Patients with POPH had more emergency department visits (1.7 ± 2.1 vs. 0.9 ± 1.2, p = 0.009) and hospitalizations in the six months preceding enrollment (1.5 ± 2.1 vs. 0.8 ± 1.1, p = 0.02). Both POPH diagnosis and lower education level were independently associated with a higher number of emergency department visits. Compared to IPAH, patients with POPH have lower socioeconomic status, are less likely to receive initial combination therapy and endothelin receptor antagonists but have similar treatment at follow-up, and have increased health-care utilization.

• Sotatercept: A New Era in Pulmonary Arterial Hypertension

  Cardiology in Review · 2025-01-07 · 5 citations

  article

  Pulmonary arterial hypertension (PAH) is a progressive disease characterized by proliferative remodeling and obliterative narrowing of the pulmonary vasculature. While outcomes have improved with existing treatments targeting 3 main pathways, there remains a critical need for novel therapies that address different and novel mechanisms of PAH. Sotatercept, recently Food and Drug Administration (FDA) approved, is a groundbreaking fusion protein that binds to activin and growth differentiation factors, rebalancing antiproliferative and pro-proliferative signals to reverse remodeling in both the pulmonary vasculature and the right ventricle. This review highlights current evidence exploring the safety and efficacy of sotatercept in the 2 landmark trials, phase 2 Pulmonary Arterial Hypertension and Sotatercept Trial and Research and phase 3 Sotatercept Treatment in Expansion of Long-term Learning and Assessment in PAH trial, which were instrumental in securing FDA approval for adult PAH patients with WHO functional class II or III symptoms already receiving background pulmonary hypertension therapy. Overall, sotatercept represents a landmark advancement in PAH treatment, offering hope for patients and the potential to delay or avoid lung transplantation. Importantly, this marks the beginning of an era of targeted therapies aimed at reverse remodeling in PAH while improving outcomes.

• Hispanic Ethnicity and Social Determinants of Health in Pulmonary Arterial Hypertension: The Pulmonary Hypertension Association Registry.

  UNC Libraries · 2025-04-18

  articleOpen access

  <strong>Rationale:</strong> There is a noticeable underrepresentation of minorities in clinical trials and registries in pulmonary arterial hypertension (PAH). Prior studies evaluating the association between Hispanic ethnicity and clinical outcomes in patients with PAH have not assessed the socioeconomic profile of Hispanic individuals or the significance of social determinants of health in clinical outcomes. <strong>Objectives:</strong> To determine the association between Hispanic ethnicity, social determinants of health, and clinical outcomes in PAH. <strong>Methods:</strong> This was a prospective cohort study of adult participants with PAH enrolled in the Pulmonary Hypertension Association Registry, a multicenter U.S.-based registry of patients treated at pulmonary hypertension care centers. Participants were classified as Hispanics and non-Hispanic White individuals, based on self-reported ethnicity. A comparison of baseline clinical and sociodemographic characteristics between groups was performed as well using absolute standardized differences (ASD). The primary outcome of the study was to assess transplant-free survival between Hispanics and non-Hispanic White individuals. A Cox proportional hazards model was used for the multivariable analysis after adjusting for age, sex, PAH etiology, annual income, education level, and health insurance. <strong>Results:</strong> A total of 683 individuals were included, 98 (14.3%) of Hispanic ethnicity. Hispanic patients had impaired access to health care (31.6% vs. 12.9% Medicaid/uninsured; ASD, 0.35), lower education level (72.6% vs. 94.0% high school graduates or higher; ASD, 0.60), and lower annual income (32.0% vs. 17.4% with income &lt;20,000 U.S. dollars; ASD, 0.47), compared with non-Hispanic White individuals. Hispanic patients had a higher frequency of emergency room visits and a higher number of hospitalizations, despite having similar disease severity (incidence rate ratio, 1.452; 95% confidence interval [CI], 1.326-1.590; and 1.428; 95% CI, 1.292-1.577, respectively). Although the unadjusted analysis showed a lower transplant/death hazard ratio for Hispanics (hazard ratio, 0.47; 95% CI, 0.24-0.94; <em>P</em>&thinsp;=&thinsp;0.032), there was no association between Hispanic ethnicity and outcome in the multivariable model after adjusting for social determinants of health and other covariates (HR, 0.76; 95% CI, 0.35-1.62; <em>P</em>&thinsp;=&thinsp;0.474). <strong>Conclusions:</strong> Hispanic ethnicity was not associated with differences in survival after adjusting for social determinants of health and other factors. Social determinants of health are important to consider when assessing the association between ethnicity and outcomes in PAH.

• Heterogeneity and Scoring Reproducibility of Folate Receptor 1 Immunohistochemistry in High-grade Serous Carcinoma

  International Journal of Gynecological Pathology · 2025-10-06 · 2 citations

  article

  Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate approved for the treatment of adult patients with folate receptor 1 (FRα; FOLR1) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. Per the FDA approval, FOLR1 positivity is defined as ≥75% of viable tumor cells showing moderate (2+) or strong (3+) membranous immunostaining ("PS2+"). Given this disease's high recurrence rate and relatively limited therapeutic options, there is utility in exploring consistency in FOLR1 reporting. Tubo-ovarian high-grade serous carcinoma (HGSC) samples from our institution's archives were included in tissue microarrays (n=806), whole tissue sections (n=51), or cell blocks (n=30) and evaluated using the Ventana FOLR1 (FOLR1-2.1) RxDx Assay. FOLR1 staining was heterogeneous across different anatomic sites (average FOLR1 PS2+ was 50.2 from adnexal sites compared with 47.4 from omental sites, P =0.015). Similarly, heterogeneity was noted in pre- versus post- neoadjuvant chemotherapy specimens (on average, FOLR1 PS2+ score increased by 17.7 from pre- to post- therapy, P =0.0089). Lastly, specimen type may also influence FOLR1 staining (average abdominal fluid FOLR1 PS2+ score was 25.5 and average surgical FOLR1 PS2+ score was 56.9, P =0.000034). Agreement among 9 readers was initially substantial, with a Fleiss kappa of 0.661 (95% CI: 0.636-0.685). For the subset of cases with the worst agreement initially, a training session with reference cases improved interobserver agreement. Our study highlights several factors contributing to heterogeneity in FOLR1 reporting. Future studies are needed to better understand the impact of FOLR1 heterogeneity on patient response to therapy.
