Purpose: Goal directed management of left heart failure with an NT-proBNP target-based approach has some evidence of providing a survival benefit. To evaluate the potential utility of serial NT-proBNP measurements for goal-directed therapy in right heart failure we retrospectively assessed NT-proBNP as a predictor for survival in Group I pulmonary arterial hypertension (PAH) patients. Methods: We identified 103 Group I PAH patients from a pulmonary hypertension registry who had baseline elevated NT-proBNP prior to either the initiation or escalation of therapy and at least two serial NT-proBNP measurements. In a two-step process, we (1) estimated baseline NT-proBNP and slope (rate of change of NT-proBNP) with a linear mixed-effects model using all patient data and then (2) compared the power of serial versus single measurements in predicting survival with measured and model-derived values of baseline NT-proBNP with a Receiver Operative Characteristic (ROC) curve analysis . Survival was determined using the Kaplan-Meier methodology. Results: ROC curve analysis revealed significantly higher AUC for model-derived NT-proBNP values compared to the measured values (AUC: for baseline 0.74 vs 0.66, p= 0.009; for slope 0.78 vs 0.66, p= 0.02). Optimal cutpoints for prediction of survival on baseline NT-proBNP were 2012 (measured) vs. 1810 (model-derived) pg/mL. The optimal cutpoint for model-derived change in NT-proBNP was -0.004 log10pg/mL/month. Sensitivity, specificity, and negative predictive values for the three predictor variables were: 64%, 67%, 80% (measured baseline NT-proBNP), 61%, 80%, 81% (model-derived baseline NT-proBNP) and 73%, 57%, 85% (model-derived slope). Conclusions: In PAH patients, serial NT-proBNP measurements better predict survival than single measurements. This retrospective finding reveals that changes in NT-proBNP are associated with overall survival in PAH patients, and set initial target values for a pilot prospective study of NT-proBNP goal-directed therapy.

Despite no significant differences of growth differentiation factor-15 expressions in peripheral, right atrial, and right ventricular blood, in the pulmonary arterial blood, there was a significantly high level of growth differentiation factor-15 in Group I pulmonary arterial hypertension patients subsequently developing heart failure. During right heart catheterization, collecting pulmonary blood samples is suggested to measure growth differentiation factor-15.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Patients (P) with acute heart failure (AHF) are a heterogeneous population. Risk stratification at admission may help predict in-hospital complications and needs. The Get With The Guidelines Heart Failure score (GWTG-HF) predicts in-hospital mortality (M) of P admitted with AHF. ACTION ICU score is validated to estimate the risk of complications requiring ICU care in non-ST elevation acute coronary syndromes. Objective To validate ACTION-ICU score in AHF and to compare ACTION-ICU to GWTG-HF as predictors of in-hospital M (IHM), early M [1-month mortality (1mM)] and 1-month readmission (1mRA), using real-life data. Methods Based on a single-center retrospective study, data collected from P admitted in the Cardiology department with AHF between 2010 and 2017. P without data on previous cardiovascular history or uncompleted clinical data were excluded. Statistical analysis used chi-square, non-parametric tests, logistic regression analysis and ROC curve analysis. Results Among the 300 P admitted with AHF included, mean age was 67.4 ± 12.6 years old and 72.7% were male. Systolic blood pressure (SBP) was 131.2 ± 37.0mmHg, glomerular filtration rate (GFR) was 57.1 ± 23.5ml/min. 35.3% were admitted in Killip-Kimball class (KKC) 4. ACTION-ICU score was 10.4 ± 2.3 and GWTG-HF was 41.7 ± 9.6. Inotropes’ usage was necessary in 32.7% of the P, 11.3% of the P needed non-invasive ventilation (NIV), 8% needed invasive ventilation (IV). IHM rate was 5% and 1mM was 8%. 6.3% of the P were readmitted 1 month after discharge. Older age (p < 0.001), lower SBP (p = 0,035) and need of inotropes (p < 0.001) were predictors of IHM in our population. As expected, patients presenting in KKC 4 had higher IHM (OR 8.13, p < 0.001). Older age (OR 1.06, p = 0.002, CI 1.02-1.10), lower SBP (OR 1.01, p = 0.05, CI 1.00-1.02) and lower left ventricle ejection fraction (LVEF) (OR 1.06, p < 0.001, CI 1.03-1.09) were predictors of need of NIV. None of the variables were predictive of IV. LVEF (OR 0.924, p < 0.001, CI 0.899-0.949), lower SBP (OR 0.80, p < 0.001, CI 0.971-0.988), higher urea (OR 1.01, p < 0.001, CI 1.005-1.018) and lower sodium (OR 0.92, p = 0.002, CI 0.873-0.971) were predictors of inotropes’ usage. Logistic regression showed that GWTG-HF predicted IHM (OR 1.12, p < 0.001, CI 1.05-1.19), 1mM (OR 1.10, p = 1.10, CI 1.04-1.16) and inotropes’s usage (OR 1.06, p < 0.001, CI 1.03-1.10), however it was not predictive of 1mRA, need of IV or NIV. Similarly, ACTION-ICU predicted IHM (OR 1.51, p = 0.02, CI 1.158-1.977), 1mM (OR 1.45, p = 0.002, CI 1.15-1.81) and inotropes’ usage (OR 1.22, p = 0.002, CI 1.08-1.39), but not 1mRA, the need of IV or NIV. ROC curve analysis revealed that GWTG-HF score performed better than ACTION-ICU regarding IHM (AUC 0.774, CI 0.46-0-90 vs AUC 0.731, CI 0.59-0.88) and 1mM (AUC 0.727, CI 0.60-0.85 vs AUC 0.707, CI 0.58-0.84). Conclusion In our population, both scores were able to predict IHM, 1mM and inotropes’s usage.

Abstract Despite substantial advancements in diagnosis and specific medical therapy in pulmonary arterial hypertension patients’ management, this condition continues to represent a major cause of mortality worldwide. In pulmonary arterial hypertension, the continuous increase of pulmonary vascular resistance and rapid development of right heart failure determine a poor prognosis. Against targeted therapy, patients inexorable deteriorate over time. Pulmonary arterial hypertension patients with acute right heart failure who need intensive care unit admission present a complexity of the disease pathophysiology. Intensive care management challenges are multifaceted. Awareness of algorithms of right-sided heart failure monitoring in intensive care units, targeted pulmonary hypertension therapies, and recognition of precipitating factors, hemodynamic instability and progressive multisystem organ failure requires a multidisciplinary pulmonary hypertension team. This paper summarizes the management strategies of acute right-sided heart failure in pulmonary arterial hypertension adult cases based on recently available data.

Introduction: In Vietnam, knowledge about renal function in adults with congenital heart disease (CHD) is limited. Hypothesis: This study aims to estimate incidence of renal dysfunction in adults with congenital heart disease and risk factors. Methods: This is a cross-sectional study, including 365 CHD patients more than 16 years old. We collected clinical and para-clinical information, estimated glomerular filtration rate (GFR) and calculated the odds ratio (OR) for reduced GFR. Results: Totally, 52.8% patients had GFR < 90 ml/phút/1.73 m 2 . Logistic regression had confirmed the OR for GFR < 90 ml/phút/1.73 m 2 in the group > 60-years-old, the group with atrial fibrillation, the group with heart failure (based on NT-proBNP > 125 pmol/L), and the group with pulmonary arterial hypertension (based on pulmonary artery systolic pressure > 50 mmHg by echocardiography) were 6.46 (95% CI: 1.37 - 30.41), 7.58 (95% CI: 1.66 - 34.56), 2.98 (95% CI: 1.49 - 5.98) and 1.84 (95% CI: 1.02 - 3.33), respectively. Conclusions: Renal dysfunction is common in adults with CHD. Age > 60 years-old, atrial fibrillation, heart failure, and pulmonary arterial hypertension were risk factors for renal dysfunction in adults with CHD.

Prostacyclin Analogues

Abstract Background Intravenous (IV) prostacyclin analogues infusion and balloon atrial septostomy (BAS) are two important treatment options for managing advanced right heart failure in patients with idiopathic pulmonary arterial hypertension (IPAH). References and protocols are rare for dose titrations and transitions between subcutaneous and IV prostacyclin in functional Class IV IPAH patients. Balloon atrial septostomy is rarely done in very few expert centres. Case summary A young female with IPAH who had received maximal medication including subcutaneous prostacyclin analogues injection was admitted due to advanced right heart failure. She received ascites drainage twice. Later, we directly switched the administration route of prostacyclin from subcutaneous to IV at a ratio of 1:1 instantly. Such rapid conversion led her into a state of profound hypotension and drowsy consciousness, which was resolved after escalating IV inotropics and reducing prostacyclin dosage. Five days later, she received BAS under the guidance of intracardiac echocardiography. Her urine output increased and dyspnoea improved gradually. Six months later, clinical worsening happened again with increase of ascites and dyspnoea. She underwent 2nd and 3rd session of graded BAS with relief of symptoms again. She received permanent transition to IV prostacyclin analogues infusions via a peripherally inserted central catheter after three sessions of BAS. Discussion Balloon atrial septostomy is effective in stabilizing the critical right heart failure in IPAH patients but should be intended as a bridge to lung transplant procedure. Transition from subcutaneous to IV prostacyclin is helpful but needs to be titrated in proper aliquots and time intervals to avoid abrupt haemodynamic changes.
