The pilot study of role of electrical cardiometry in non‑invasive assessment of hemodynamic parameters in patients with pulmonary arterial hypertension (RCD code: II‑1A.1)
Journal Title: Journal of Rare Cardiovascular Diseases - Year 2017, Vol 3, Issue 2
Abstract
Background: Electrical cardiometry (EC) technique could estimate cardiac output (CO), cardiac index (CI) and other parameters related to cardiac contractility and fluid status by measuring the thoracic electrical bioimpedance. We hypothesized that EC could assess right ventricle (RV) hemodynamic function in patients diagnosed with pulmonary arterial hypertension (PAH). Results: In our pilot study, enrolling 23 PAH patients, we observed a significant correlation (r = 0.71; p <0.001) between thermodilution CO measurement results (4.59 ±1.05 l/min) and CO results obtained by EC (4.86 ±1.20 l/min) and between systemic vascular resistance calculated by EC monitor and obtained during right heart catheterization (RHC) (r = 0.68; p = 0.002). Furthermore, EC parameter index of contractility (ICON) sig‑ nificantly correlated with tricuspid annular plane systolic excursion assessed by echocardiography (r = 0.57; p = 0.01). Conclusions: RHC cannot be replaced in obtaining accurate results of CO, however EC technique provides feasible insight into RV function at the bedside or outpatient care. JRCD 2017; 3 (2): 44–49

Effect of first‑month specific therapy determines long‑term clinical outcome in patients with pulmonary arterial hypertension
Efficacy of pulmonary arterial hypertension (PAH)-specific therapy may differ among the patients depending on the PAH aetiology. Aim: To compare the real‐life efficacy of PAH‐specific therapy between non‐congenital hear...
