Our objective was to evaluate the utility of the natriuretic peptides BNP (brain natriuretic peptide) and NT-proBNP as markers of pulmonary artery systolic pressure (PASP) in trekkers ascending to high altitude (HA). 20 participants had BNP and NT-proBNP assayed and simultaneous echocardiographic assessment of PASP performed during a trek to 5150 m. PASP increased significantly (p=0.006) with ascent from 24±4 to 39±11 mm Hg at 5150 m. At 5150 m those with a PASP≥40 mm Hg (n=8) (versus those with PASP<40 mm Hg) had higher post-exercise BNP (pg/ml): 54.5±36 vs. 13.4±17 (p=0.012). Their resting BNP at 5150 m was also higher: 57.3±43.4 vs. 12.6±13 (p=0.017). In those with a pathological (≥400 pg/ml) rise in NT-proBNP at 5150 m (n=4) PASP was significantly higher: 45.9±7.5 vs. 32.2±6.2 mm Hg (p=0.015). BNP and NT-proBNP may reflect elevated PASP, a central feature of high altitude pulmonary oedema, at HA.

Background: Right ventricular-pulmonary artery coupling (RVPAC) is a predictor of outcome in pulmonary hypertension. However, the role of this parameter in dilated cardiomyopathy (DCM) remains to be established. The aim of this study was to assess the contribution of RVPAC to the occurrence of severe heart failure (HF) symptoms in patients with DCM using three-dimensional (3D) echocardiography. Methods: We prospectively screened 139 outpatients with DCM, 105 of whom were enrolled and underwent 3D echocardiographic assessment. RVPAC was estimated non-invasively as the 3D right ventricular stroke volume (SV) to end-systolic volume (ESV) ratio. Severe HF symptoms were defined by New York Heart Association (NYHA) class III or IV. We evaluated differences in RVPAC across NYHA classes and the ability of RVPAC to predict severe symptoms. Results: Mean left ventricular (LV) ejection fraction was 28±7%. Mean RVPAC was 0.77±0.30 and it was significantly more impaired with increasing symptom severity (p=0.001). RVPAC was the only independent correlate of severe HF symptoms, after adjusting for age, diuretic use, LV systolic function, LV diastolic function and pulmonary artery systolic pressure (OR 0.035 [95% CI, 0.004 – 0.312], p=0.003). By receiver-operating characteristic analysis, the RVPAC cut-off value for predicting severely symptomatic status was 0.54 (area under the curve=0.712, p<0.001). Conclusion: 3D echocardiographic SV/ESV ratio is an independent correlate of severe HF symptoms in patients with DCM. 3D RVPAC might prove to be a useful risk stratification tool for these patients, should it be further validated in larger studies.

Background: Heart failure(HF) related early readmission (<30days) and mortality is higher in elderly patients. Right ventricular (RV) dysfunction is associated with worse prognosis in patients with HF with reduced ejection fraction (HFrEF). We evaluated effect of RV function (as measured by TAPSE - Tricuspid annular plane systolic excursion) and Pulmonary artery systolic pressure (PASP) on early HF readmission and mortality in elderly HF patients. Methods: This is single center observational study of elderly (≥65 years )patients with HFrEF. Patients with principal discharge diagnosis of HFrEF are included (n = 278, age 77 ± 9 years, 38% female, LVEF 29% ± 9%). Demographic and echocardiographic data are collected. TAPSE (as a marker of RV systolic dysfunction) and PASP are measured as per ASE guidelines. Prediction models are performed. Results: Among 278 patients, 62 patients ( 22.3%) had HF related early readmission and 123 patients (44%) died at the end of 5 year. On univariate analysis, older age, Hypertension, Diabetes, higher PASP , RV systolic dysfunction (TAPSE <16mm) and BMI< 25 are predictors of early readmission and mortality (P value <0.05). On multivariate logistic regression analysis, early HF readmission was predicted by TAPSE <16 mm (OR=23.6; p < 0.001; CI 10.23-54.60) and PASP >50 mmHg ( OR = 34; p < 0.001; 95 CI 14.08-82.81); five year all cause mortality was predicted by TAPSE < 16mm (OR = 1.85; p 0.023; 95 CI 1.08-3.16) and PASP >50 mmHg (OR = 2.11; p 0.009; 95 CI 1.19-3.72). Conclusion: TAPSE <16 mm and PASP >50 mmHg are strong predictors of early readmission and five year all cause mortality in elderly HF patients. The assessment of RV function through TAPSE and PASP, helps to risk-stratify elderly patients with HFrEF.

Introduction Chronic thromboembolic pulmonary hypertension results from the incomplete resolution of the vascular obstruction associated with pulmonary embolism. Symptoms are exertional dyspnoea and fatigue, and over a period of time, right ventricular dysfunction sets in. Pulmonary thromboendarterectomy is an effective surgical remedy for this condition. Our study is an initial post-operative experience of pulmonary thromboendarterectomy and we have also tried to formulate quantitative parameters for the prediction of the post-operative course in patients who are undergoing surgery. Methods Twenty patients with chronic thromboembolic pulmonary hypertension underwent pulmonary thromboendarterectomy between July 2017 and January 2020. Pre-operatively, each patient was subjected to the (i) 6-min walk test, (ii) pre-operative brain natriuretic peptide values and (iii) pulmonary artery systolic pressure. Following the surgery and subsequent discharge, the patients were followed up at intervals of 15 days, 1, 3, 6, 9 months and at 1 year. At one year post-operatively, the same three quantitative tests were performed on each subject. Results Post-operatively, the mean 6-min walk distance was 499.75 m as against 341.35 m pre-operatively ( p < 0.0001). Mean brain natriuretic peptide was 8.69 pm/l as against 47.58 pm/l pre-operatively ( p < 0.0001). Mean pulmonary artery systolic pressure was 22.25 as against 67.1 pre-operatively ( p < 0.0001). Conclusion 6-Min walk test, brain natriuretic peptide and pulmonary artery systolic pressure could be considered as useful predictors of the haemodynamic severity of disease and predict the post-operative outcome.
