Filter by:Arrhythmias are considered a prominent phenomenon in pulmonary hypertension (PH) as the disease progresses. According primarily to retrospective studies with up to 24 hours of monitoring, supraventricular tachycardias (SVT) can be found in 8-35% of patients, with significant impact on survival. Furthermore, a few prospective studies to date deploying short-term monitoring (10 minutes-24 hours) have revealed lower heart rate variability (HRV) in patients with pulmonary arterial hypertension (PAH). In ASPIRE arrhythmias and heart rate variability is being assessed via long term monitoring. Currently the the loop-recorder is considered the gold standard for long-term continuous cardiac montoring. A non-invasive continuous monitoring could be of a great benefit for the patients, and could potentially contribute to treatment optimization. The study will assess apple watches as a non-invasive tool compared to to the loop recorder, which is considered as the current gold standard. Additionally, the study seeks to assess apple watches for monitoring as an independent wearable for risk assessment in PH.
Cardiac dysfunction has been reported to be common in patients infected with COVID-19. The aim of this study is to evaluate the clinical importance of cardiac dysfunction in critically ill patients infected with COVID-19.
Pediatric idiopathic pulmonary hypertension has significant morbidity and mortality. An ever expanding body of knowledge indicates the important contribution of inflammation to pathogenesis and successful treatment with glucocorticoids. Over the last several years the investigators have utilized steroids in patients with severe pulmonary hypertension as part of a treatment regimen. These basic science studies possibly identifies a biochemical etiology for the development of disease and may also be impacted by the administration of steroids. Additionally, there is a commercially available assay which tests for all of the above molecules.
Pulmonary hypertension (PH) is a disorder of high blood pressure that impacts the heart and lungs. Approximately, 50% of individuals with PH experience anxiety or panic disorders. There is limited evidence on psychological treatments for anxiety in PH; however, results support the use of Cognitive Behavioural Therapy (CBT). Despite the prevalence and impact of anxiety in PH; there are no widely available and/or disease specific pathways, thus highlighting an unmet need in this population. This project aims to develop and pilot, using randomised control trial methodology, a self-management intervention for individuals with PH based on principles of CBT.
Progressive SSc is an entity with limited therapeutic alternatives and with asurvival rate of less than 45% in the first 3 to 5 years. The disease causessevere limitation in quality of life ranging from functional limitation to depression. Up to 20% of patients will be refractory to conventional treatment with diseasemodifying anti-rheumatic drugs (DMARDs) and cyclophosphamide therapy.This favors the progression to visceral involvement including gastrointestinal,lung and pulmonary hypertension. The latter being a poor prognostic factor,increases mortality in this group of patients and drastically affects their qualityof life. For this reason, different therapeutic options have been considered including cell transplantation and Stem Cell use. Among the options that have been studied so far are stromal mesenchymal cells from Wharton ́s jelly. These have been used in intravenous infusion or direct application in different disease scenarios ranging from vascular involvement to interstitial lung involvement and cases of pulmonary hypertension, with promising results in terms of clinical progression,improvement in quality of life and prognostic indices. This therapy has proven to have a significant margin of safety at the time of administration and a low rate of adverse events, a self-limiting fever as the most frequent event. Based on the above and considering the possibility of offering patients without therapeutic alternatives to their disease in addition to palliative options, an intravenous infusion of stromal mesenchymal stem cells from Wharton ́s jellyis proposed for three patients with progressive SSc refractory to conventional therapy with pulmonary involvement due to pulmonary hypertension. Under this premise the question posed in our work is; What are the effects of the infusion of allogeneic mesenchymal stromal cells from Wharton ́s jellyin patients with systemic sclerosis refractory to conventional treatment with Methotrexate or Cyclophosphamide in a population of three patients with severe pulmonary involvement due to pulmonary hypertension.
Chronic pulmonary hypertension (cPHT) is a serious cardiopulmonary disorder that causes low oxygen levels in the blood, difficulty in breathing and ultimately heart failure. Newborn babies born extremely premature frequently suffer from cPHT while receiving treatment in neonatal intensive care units and are more likely to die than those without cPHT. Echocardiography is the investigation of choice for the assessment of heart function in premature infants however however there is a significant lack of standardization, sensitivity, and reliability for echocardiography parameters and a lack of consensus regarding optimal detection timing. In adults and older children it is known that early diagnosis and treatment, particularly before right side of the heart fails, is an important determinant of treatment success and survival. Diagnosis late in postnatal course for preterm infants remains a major barrier to timely and effective treatment. The primary objective of this study is to develop new, sensitive, quantitative echocardiographic diagnostic criteria which will allow for the identification of extreme preterm neonates suffering from significantly high pressure in their pulmonary blood vessels, early in postnatal course, when the disease is likely to be most amenable to preventative/curative treatment. This is an international initiative that will leverage expertise about echocardiography techniques and cardiopulmonary physiology of preterm infants.The results of this study will have an immediate impact on the day-to-day care of these highly vulnerable infants. The results will lead to increased awareness among clinicians, inform future surveillance protocols and diagnostic timing, and provide ideal preparation for future therapeutic trials.
This is an observational study of Neuregulin-1 (NRG-1) plasma levels in patients with different forms of cardiovascular disease including microvascular angina (MVA), heart failure with preserved ejection fraction (HFpEF), as well as, heart failure with reduced ejection fraction (HFrEF) and pulmonary hypertension (PH). Investigators intend to identify cardiovascular diseases which are characterized by increased circulating NRG-1, considered to be a biomarker of therapeutic potential of NRG-1. Participants will undergo blood sampling over 3 days following randomisation. Patients demographics and clinical characteristics will be recorded and their associations with NRG-1 will be analysed.
The study will test the ability a novel wearable sensor based on a smartphone app (Precordior CardioSignal app) in combination with a sensor device (Suunto Movesense sensor) to non-invasively measure cardiac motion and function.
Pulmonary hypertension is a major determinant of postnatal survival in infants with a congenital diaphragmatic hernia (CDH). The current care during the perinatal stabilisation period in infants born with this rare birth defect might contribute to the development of pulmonary hypertension after birth - in particular umbilical cord clamping before lung aeration. An ovine model of diaphragmatic hernia demonstrated that cord clamping after lung aeration, called physiological-based cord clamping (PBCC), avoided the initial high pressures in the lung vasculature while maintaining adequate blood flow, thereby avoiding vascular remodelling and aggravation of pulmonary hypertension. The investigators aim to investigate if the implementation of PBCC in the perinatal stabilisation period of infants born with a CDH could reduce the incidence of pulmonary hypertension in the first 24 hours after birth. The investigators will perform a multicentre, randomised controlled trial in infants with an isolated CDH. Before birth, infants will be randomised to either PBCC or immediate cord clamping, stratified by treatment centre and severity of pulmonary hypoplasia on antenatal ultrasound. For performing PBCC a purpose-designed resuscitation module (the Concord Birth Trolley) will be used.
The primary objectives of this study are to assess the safety/tolerability and efficacy (by evaluating changes in pulmonary vascular resistance [PVR] and pulmonary blood volume [PBV]) of MK-5475 in participants with pulmonary hypotension associated with chronic obstructive pulmonary disease (PH-COPD). The primary hypothesis is that 28 days of MK-5475 treatment is superior to placebo treatment in reduction of PVR.
