J Am Heart Assoc 2024; 13:e034151. [PMID: 38904230 PMCID: PMC11255703 DOI: 10.1161/jaha.123.034151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 05/10/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND In pulmonary arterial hypertension, it is recommended to base therapeutic decisions on risk stratification. This systematic review aims to report the prognostic value of serial risk stratification in adult and pediatric pulmonary arterial hypertension and to explore the usability of serial risk stratification as treatment target. METHODS AND RESULTS Electronic databases PubMed, Embase, and Web of Science were searched up to January 30, 2023, using terms associated with pulmonary arterial hypertension, pediatric pulmonary hypertension, and risk stratification. Observational studies and clinical trials describing risk stratification at both baseline and follow-up were included. Sixty five studies were eligible for inclusion, including only 2 studies in a pediatric population. C-statistic range at baseline was 0.31 to 0.77 and improved to 0.30 to 0.91 at follow-up. In 53% of patients, risk status changed (42% improved, 12% worsened) over 168 days (interquartile range, 137-327 days; n=22 studies). The average proportion of low-risk patients increased from 18% at baseline to 36% at a median follow-up of 244 days (interquartile range, 140-365 days; n=40 studies). In placebo-controlled drug studies, risk statuses of the intervention groups improved more and worsened less compared with the placebo groups. Furthermore, a low-risk status, but also an improved risk status, at follow-up was associated with a better outcome. Similar results were found in the 2 pediatric studies. CONCLUSIONS Follow-up risk stratification has improved prognostic value compared with baseline risk stratification, and change in risk status between baseline and follow-up corresponded to a change in survival. These data support the use of serial risk stratification as treatment target in pulmonary arterial hypertension.

Abstract
Patients with pulmonary hypertension associated with a left-right shunt include a wide spectrum of pathophysiological substrates, ranging from those characterized by pulmonary over-circulation to those with advanced pulmonary vascular disease. The former group may benefit from shunt repair in carefully selected cases but, when advanced pulmonary vascular disease has developed, defect closure should be avoided, and pulmonary vasodilators may be used to improve effort tolerance and hemodynamics. There is a paucity of evidence, however, to support decision-making in the care of these patients. We discuss the principles of management in patients with pulmonary hypertension and a predominant left-right shunt. The recommendations and statements made in this paper are based on pathophysiological considerations and expert opinion.

Characteristics, treatments and survival of pulmonary arterial hypertension associated with congenital heart disease in China: Insights from a national multicenter prospective registry. J Heart Lung Transplant 2023; 42:974-984. [PMID: 37002152 DOI: 10.1016/j.healun.2023.02.1494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 01/15/2023] [Accepted: 02/19/2023] [Indexed: 02/27/2023] Open
Abstract
BACKGROUND The purpose of this registry was to provide insights into the characteristics, treatments and survival of patients with PAH-CHD in China. METHODS Patients diagnosed with PAH-CHD were enrolled in this national multicenter prospective registry. Baseline and follow-up data on clinical characteristics, PAH-targeted treatments and survival were collected. RESULTS A total of 1060 PAH-CHD patients (mean age 31 years; 67.9% females) were included, with Eisenmenger syndrome (51.5%) being the most common form and atrial septal defects (37.3%) comprising the most frequent underlying defect. Approximately 33.0% of the patients were in World Health Organization functional class III to IV. The overall mean pulmonary arterial pressure and pulmonary vascular resistance were 67.1 (20.1) mm Hg and 1112.4 (705.9) dyn/s/cm5, respectively. PAH-targeted therapy was utilized in 826 patients (77.9%), and 203 patients (19.1%) received combination therapy. The estimated 1-, 3-, 5-, and 10-year survival rates of the overall cohort were 96.9%, 92.9%, 87.6% and 73.0%, respectively. Patients received combination therapy had significantly better survival than those with monotherapy (p = 0.016). NT-proBNP >1400 pg/ml, SvO2 ≤ 65% and Borg dyspnea index ≥ 3 and PAH-targeted therapy were independent predictors of mortality. Hemoglobin > 160g/L was a unique predictor for mortality in Eisenmenger syndrome. CONCLUSIONS Chinese PAH-CHD patients predominantly exhibit Eisenmenger syndrome and have significantly impaired exercise tolerance and right ventricular function at diagnosis, which are closely associated with long-term survival. PAH-targeted therapy including combination therapy showed a favorable effect on survival in PAH-CHD. The long-term survival of Chinese CHD-PAH patients remains to be improved.

Abstract
IntroductionCurrently, risk stratification is the cornerstone of determining treatment strategy for patients with pulmonary arterial hypertension (PAH). Since the 2015 European Society of Cardiology/European Respiratory Society (ESC/ERS) guidelines for the diagnosis and treatment of pulmonary hypertension recommended risk assessment, the number of studies reporting risk stratification has considerably increased. This systematic review aims to report and compare the variables and prognostic value of the various risk stratification models for outcome prediction in adult and pediatric PAH.MethodsA systematic search with terms related to PAH, pediatric pulmonary hypertension, and risk stratification was performed through databases PubMed, EMBASE, and Web of Science up to June 8, 2022. Observational studies and clinical trials on risk stratification in adult and pediatric PAH were included, excluding case reports/series, guidelines, and reviews. Risk of bias was assessed using the Prediction model Risk Of Bias Assessment Tool. Data on the variables used in the models and the predictive strength of the models given by c-statistic were extracted from eligible studies.ResultsA total of 74 studies were eligible for inclusion, with this review focusing on model development (n = 21), model validation (n = 13), and model enhancement (n = 9). The variables used most often in current risk stratification models were the non-invasive WHO functional class, 6-minute walk distance and BNP/NT-proBNP, and the invasive mean right atrial pressure, cardiac index and mixed venous oxygen saturation. C-statistics of current risk stratification models range from 0.56 to 0.83 in adults and from 0.69 to 0.78 in children (only two studies available). Risk stratification models focusing solely on echocardiographic parameters or biomarkers have also been reported.ConclusionStudies reporting risk stratification in pediatric PAH are scarce. This systematic review provides an overview of current data on risk stratification models and its value for guiding treatment strategies in PAH.Systematic review registration[https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022316885], identifier [CRD42022316885].

Abstract
OBJECTIVE The role of preoperative N-terminal pro-brain natriuretic peptide level in patient outcomes after the Fontan operation remains unclear. METHODS The medical records of all patients who underwent their first Fontan operation from June 2011 to October 2019 in our tertiary referral pediatric cardiac center were retrospectively reviewed. Preoperative hemodynamic factors and N-terminal pro-brain natriuretic peptide were analyzed to test the association of mortality and morbidity. RESULTS We enrolled 110 patients (men/women 62/48; median age, 4.1 [3.4, 5.8] years; median follow-up period, 4.28 [2.31, 6.71] years). Almost all operations were extracardiac conduits (98.2%). Primary outcomes of death, Fontan takedown, and heart transplantation were observed in 9 patients (8.2%). Abnormal ventricular contractility, elevated preoperative pulmonary artery pressure, high pulmonary vascular resistance index, and high log10 N-terminal pro-brain natriuretic peptide level were associated with poor outcomes. SECONDARY OUTCOMES atrioventricular valve regurgitation moderate or greater, elevated pulmonary artery pressure, high pulmonary vascular resistance index, and high log10 N-terminal pro-brain natriuretic peptide level were associated with rehospitalization due to heart failure. Multivariable Cox regression analysis revealed that log10 N-terminal pro-brain natriuretic peptide was the only significant predictor of all primary and secondary outcomes. A scoring system including factors of pulmonary artery pressure, pulmonary vascular resistance index, and N-terminal pro-brain natriuretic peptide was established, and the risk stratification is associated with outcomes after the Fontan operation. CONCLUSIONS High preoperative N-terminal pro-brain natriuretic peptide was associated with poor outcomes after the Fontan operation.

Abstract
Background The epidemiology of pulmonary hypertension (PH) in patients with adult congenital heart disease in Western countries is already known. We investigate clinical characteristics of PH in adult congenital heart disease with emphasis on complex congenital heart disease (CHD) from an Asian cohort in Taiwan. Methods and Results All adult patients (aged >18 years) diagnosed with CHD between January 2007 and July 2018 qualified for the study. PH was determined by cardiac catheterization data or echocardiography reports. In accord with the World Symposia on Pulmonary Hypertension, CHD was further categorized as simple, severe, or complex CHD (including pulmonary atresia‐ventricular septal defect and single‐ventricle anomalies). There were 4301 patients (55.6% women), 15.7% with severe and 3.9% with complex CHD. The cumulative incidence of PH was 4.4% (95% CI, 3.8–5.0). Our multivariable regression model indicated 4.2‐fold mortality increase (95% CI, 3.0–5.9) in the presence of PH, with age, female sex, and severe or complex CHD linked to higher incidence of PH. Only 49% of patients received PH‐specific therapy. Five‐ and 10‐year survival rates of patients with PH (n=190) were 72.3% (95% CI, 65.1%–78.4%) and 58.8% (95% CI, 50.1%–66.5%), respectively. Survival rates in those with Eisenmenger syndrome, PH after defect correction, and complex CHD were similar. Low oxygen saturation and high uric acid levels were associated with increased mortality. Conclusions In this sizable Asian adult CHD cohort, the cumulative incidence of PH was aligned with that of Western countries. Mortality proved higher in patients with PH versus without PH. Although complex CHD carried greater risk of PH compared with other adult CHD subsets, survival rate was similar.

Abstract
The vast majority of patients with congenital heart disease (CHD) survive into adulthood, but many face lifelong complications, which often result in a hospital admission. The increasing number of hospitalizations in adults with CHD (ACHD) poses a significant challenge for healthcare systems globally, especially as heart failure (HF) is becoming increasingly common in this population and is the leading cause of morbidity and mortality. Besides HF, other major contributors to this increase in admission volume are hospitalizations related to mild lesions, comorbidities and pregnancies. Ιn-hospital mortality ranges between 0.8 and 6.1%, while hospitalizations related to HF predict medium-term mortality in ACHD population. Understanding the predictors of hospitalization and in-hospital mortality is, therefore, important for ACHD healthcare providers, who should identify patients at risk that require escalation of treatment and/or close monitoring. This article reviews the available literature on hospitalization patterns in ACHD patients, with a focus on HF-related hospital admissions and specific diagnostic subgroups.
