Filter by:The study aims to describe the clinical characteristics and clarify the predictors of the short- and long-term outcomes of RHF patients, further assist the diagnosis, risk stratification and treatment of RHF.
This prospective double blinded randomized study aims to compare the effect of inhaled versus intravenous milrinone on the pulmonary vascular resistance in patients undergoing mitral valve replacement surgery. The primary outcome is to determine change in pulmonary artery pressure. The secondary outcomes include, - Incidence of systemic hypotension. - Hemodynamic affection and need of vasopressors and inotropes. - Change in pulmonary vascular resistance versus systemic vascular resistance. - Right ventricular function. - Duration of mechanical ventilation. - Need for mechanical circulatory support devices. - Urine output - Length of intensive care (ICU) in stay. As the investigators hypothesize that inhaled milrinone has a selective pulmonary vasodilator effect devoid of the systemic hypotension with the intravenous administration.
A randomized, double-blind, placebo-controlled dose escalation study to assess the safety and efficacy of pulsed, inhaled nitric oxide (iNO) in subjects with pulmonary fibrosis on long term oxygen therapy.
Our study aims to investigate the changes in muscle strength and muscle mass in PAH patients compared to healthy individuals and determine its effects on prognosis. Further categorization of PAH patients based on their NYHA class will help determine if their handgrip strength decreases while progressing from NYHA class 1 to 4. This in turn allows us to examine if the handgrip test can be considered as an alternative to a 6-minute walking test (6MWT). The Jamar Hydraulic Hand Dynamometer device in our hospital is used for measuring the handgrip strength test. The data of the included subjects in this study are obtained and recorded from the existing files. Also, the handgrip strength test data will be recorded after the investigation
Cognitive behavioral therapy (CBT-I) is a common treatment for insomnia that does not use medications. While CBT-I is effective for insomnia, it does not tend to improve the waking symptom of fatigue. Another treatment, Bright Light Therapy, is used for treating seasonal depression and sleep disorders, and may improve fatigue and physical activity in individuals with PAH. The purpose of this study to assess the effects of Bright Light Therapy compared to CBT-I to treat insomnia and fatigue in patients with PAH.
Pulmonary hypertension (PH) is a life threatening condition. In PH, pulmonary arterial hypertension (PAH) and chronic thrombo-embolic chronic pulmonary hypertension (CTEPH) are two rare diseases requiring specific and complex drug management. In France ,a part of these treatments ,only available in hospital pharmacies, are generally unknown from community health care professionals despite the high risk of drug-interactions and side effects. Anticipating medication errors at the begging of the disease is therefore important, and could be done through medication reconciliation.
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.
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.
Researchers are evaluating quality of life in pulmonary hypertension subjects using the Pulmonary Arterial Hypertension-Symptoms and Impact (PAH-SYMPACT) Questionnaire and assessing the questionnaires' performance with regard to relationship to other markers of disease severity, response to treatment, and outcome in a clinical practice setting.
Sildenafil is a phosphodiesterase inhibitor that can exert a nitric oxide-mediated vasodilation effect, so it's considered one of the preferred agents especially in hypoxia induced pulmonary hypertension, can achieve pulmonary vasodilation by enhancing sustained levels of cyclic guanosine monophosphate (cGMP) and nitric oxide. Despite the potential burden of pulmonary hypertension in hemodialysis patients, such agent like sildenafil has limited studies about optimum dose, safety and long term efficacy in End stage renal disease patients on hemodialysis with pulmonary hypertension
