In this explorative study, we aim to investigate whether MVR obtained with Doppler flow velocity, is a better predictor of adverse outcome than PVR obtained with Swan-Ganz measurements.
PRIMARY OBJECTIVE:To determine the contractile strength and the (ultra)structure of single diaphragm muscle fibers of CTEPH patients SECONDARY OBJECTIVES:1. To determine whether diaphragm muscle fiber weakness is part of a generalized muscle…
1. To characterize and compare RV myocardial structure, contraction patterns, and functional capacity of (A) PH patients (group 1 or 4, the latter are to be inoperable), (B) patients with pressure overloaded RV due to CHD and (C) healthy controls. 2…
The proposed project focuses on: a) implementation of an improved, standardized method for performing quantitative nailfold capillaroscopy to visualize morphological patterns and evaluate its diagnostic use in patients with (possible) CTD and…
To assess, by use of MRI measurements during exercise, the level of restoration of cardiac function, and to study whether excercise limitation in CTEPH patients after a hemodynamically succesful PEA is caused by an impaired RV stroke volume response…
To study whether inflammmation plays a role in patients with RV disease, and can be detected with Gallium-67 scintigraphy
The primary aim of this observational study is to determine the occurrence of exercise-induced left ventricular diastolic dysfunction (LV-DD) in symptomatic COPD patients with a normal echocardiography at rest. And, secondly, to study the…
Cardiac surgery patients are often exposed to blood products perioperatively (18). Due to their underlying cardiac condition and ventricular dysfunction these patients are at an increased risk for TACO.(19) In a *proof of principle* approach we will…
The primary objective of this study is to investigate the role of vascular cells, with focus on pulmonary arterial endothelial cells (PAEC), in the development and pathogenesis of extensive thromboembolisms as observed in CTEPH.
Therefore, the aim of our study is to determine whether and when changes in sympathetic signalling in the RV of IPAH patients occur, using [11C]-HED and [11C]-CGP-12177 PET imaging.
The aim of this study is to evaluate the effects of treatment on the exertional contractile reserve and RV-arterial coupling during exercise in CTEPH patients. Furthermore, we evaluate the effects on the exertional contractile reserve and RV-…
Primary Objectives:- Determine the effect of pulmonary vasodilatation on indexed cardiac output during simulated exercise.- Characterization of structural properties of small pulmonary arteries.Secondary Objectives: - Investigate the effect of…
The first objective of the study is to predict the prevalence of PH in sarcoidosis with pulmonary involvement, and to optimize the diagnostic approach in screening for PH associated sarcoidosis using the RHC as gold standard (Galie, 2009). The…
We hypothesize that the development of a follow-up program of unaffected mutation carriers will lead to early identification of disease and in the development of strategies to prevent the development of disease and successful treatment.
Assess BMP10 secretion in patients with pulmonary arterial hypertension and its effect on right ventricular adaptation to pressure overload.
To evaluate post-operative neurologic damage using clinical data on delirium and neuropsychological testing for long term postoperative decline, in combination with measures of NfL, GFAP and Tau in CTEPH patients treated with PEA or BPA in the…
We aim to identify if pediatric PAH patients have increased plasma IL-1β and IL-18 compared to control participants, as well as increased caspase-1 cleavage and NLRP3, IL-1β and IL-18 mRNA expression in PBMCs, reflective of inflammasome activation.…
