Filter by:This is a multi-center, perspective, and exploratory study aimed at evaluating the 3-years clinical outcome of Potts-shunt procedure for pediatric patients with severe pulmonary artery hypertension (PAH). The included criteria are as followed: 1)6 months < age ≤ 18 years; 2) ESC 2022 Group I PAH; 3) Have received standardized drug therapy for at least 6-9 months and still remain at intermediate to high/high-risk status of the criteria of ESC2022; 4) Presenting with significant clinical manifestations (i.e., progressive symptoms/syncope history/growth and development restriction, etc); 5) Informed consent form signed by the patient and their guardian. The excluded criteria are as followed: 1) ESC 2022 Group II-V PAH; 2) Poor right ventricular function: RVEF < 25% or RVFAC < 20%; 3) Deteriorated general condition: requiring ICU resuscitation or ECMO assistance; 4) Pulmonary artery pressure/main arterial pressure ratio < 0.7; 5) Six-minute walk distance < 150 meters (only applicable to patients aged 8 and above); 6) No significant improvement in RVEF under triple drug therapy. All of the pediatric patients with severe PAH who attend to pediatric cardiac outpatient clinic and meet the designed included criteria and excluded criteria will be enrolled in this study. All of the participants will be divided into two groups (Potts-shunt combined with conventional drug therapy group and only conventional drug therapy group) according to their individual health status (i.e., some contraindications of surgery) and their (or their parents') aspiration for Potts-shunts procedure. Follow-up is designed (eight-times follow-up) at the time of Potts-shunt procedure, post-operative ICU period, one month, three months, six months, one year, two years, and three years after Potts-shunt procedure or the rejection of Potts-shunt procedure. The items of follow-up include state of survival, whether or not have the lung transplantation (LTx), clinical manifestation, laboratory examination, function of right ventricle (detected by echocardiogram and cardiac magnetic resonance imaging), and the pulmonary circulation pressure (detected by right heart catheterization or Swan-Ganz catheterization). Primary outcome is the incidence rates of death or LTx three-years after Potts-shunt. Secondary outcomes are as followed: 1) Number and incidence rate of postoperative complications in patients undergoing Potts-shunt procedure; 2) Three-year WHO cardiac functional and 6-minute walk distance after Potts-shunt procedure; 3) the NT-ProBNP levels three-years after Potts-shunt procedure; 4) Right ventricular function on echocardiography three years after Potts-shunt procedure; 5) Right ventricular function on cardiac magnetic resonance imaging three years after Potts-shunt procedure; 6) Pulmonary circulation pressure measured by right heart catheterization or Swan-Ganz catheterization three years after Potts-shunt procedure; 7) Three-year mortality or LTx incidence rates after only conventional drug therapy.
This study aimed to assess the effect of the supplementation with grape seed extract (GSE) on blood pressure during static handgrip exercise and muscle metaboreflex in individuals with elevated and state 1 hypertension.
In this study, researchers want to learn about the safety of BAY3283142 after a single dose and multiple doses in participants with mild to moderate high blood pressure. The study treatment called BAY3283142 helps to relax blood vessels. It is currently under development for the treatment of chronic kidney disease (CKD) and nonproliferative diabetic retinopathy (NPDR). CKD is a condition in which the kidneys' ability to work gradually decrease over time. NPDR is a condition in which high blood glucose levels cause damage to the blood vessels of the retina, which is a tissue at the back of the eyes. During this study, participants will take either different doses of the study drug BAY3283142 as tablets by mouth or a placebo. A placebo looks like the study drug but does not have any medicine in it. At the start of this study, the study doctor will check the medical history and current medications of the participants. They will also perform a complete health check on all the participants. Researchers will collect blood and urine samples from the participants at different time points to assess the safety and effects of BAY3283142. Each treatment scheme will consist of three doses that are given in a consecutive manner. For the first 7 days, participants will receive a lower dose of BAY3283142 in each treatment scheme. The middle and the higher dose of each treatment scheme will be given for 14 days each. Participants will not know which treatment (placebo or BAY3283142) they will be given, but the study doctor will know which group received which treatment. A participant can be in the study for 10 weeks. This study will be conducted on men or postmenopausal women participants with mild to moderate high blood pressure who may not directly benefit from treatment with BAY3283142. However, information collected in this study will serve as a basis for the development of BAY3283142 for the treatment of people with CKD or NPDR. Participants may experience pain and discomfort when blood samples are taken. The researchers will closely monitor and manage any medical problems that the participants may have during the study.
The purpose of study is to understand the different factors (patient, societal, provider, clinic, health system) relevant in recruitment and participation of patients in Team Based Equity Conscious Telemedicine Approach to Improve Hypertension clinical trial.
The purpose of this study is to evaluate the safety, tolerability, efficacy, pharmacodynamics (PD) and pharmacokinetics (PK) of zilebesiran in Japanese patients with mild to moderate hypertension.
Preeclampsia (PE) is a significant cause of maternal and fetal morbidity and mortality, characterized by high blood pressure and proteinuria during pregnancy. It has two main phenotypes: one linked to placental damage and the other to metabolic factors like obesity. Early identification of high-risk groups is crucial, though there's ongoing disagreement over its classification. Research suggests a potential connection between maternal gut bacteria and PE, offering avenues for improved prevention strategies. This study aims to investigate the differences in maternal gut microbiota between these two PE phenotypes.
Lifestyle medicine is a medical specialty that uses evidence-based therapeutic interventions to prevent, treat, and reverse chronic conditions. Studies have shown that a 50 mg/dl reduction in LDL reduces the risk of developing stroke by 20%, and a 10 mm Hg reduction in systolic BP reduces the risk of developing MACE by 22% and stroke by 41%. The CLIP (Cholesterol Lowering Lifestyle Intervention Project) is an innovative initiative proposed to evaluate the combined effect of an Indian version of Portfolio diet-based nutrition strategy, intermittent fasting, exercise, sleep, and stress reduction techniques on lowering blood lipid levels in health professionals and their family. The study aims to evaluate the effect of CLIP on changes in blood pressure, weight, HbA1C levels, blood CRP levels, and other blood parameters.
This is a randomized, placebo-controlled, double-blinded crossover design. Nineteen patients with essential hypertension will be randomized to receive either ketone bodies (KE4) or placebo delivered by KetoneAid. After a period of 5-days treatment, effect variables will be measured (experiment day 1). After a washout period of 14 days, the subjects are crossed over to a similar treatment period with the other treatment. The study is terminated by measuring effect variables after the second treatment period (experiment day 2).
Atrial fibrillation (AF) is the most common type of abnormal heart rhythm. This occurs as the chambers of the heart pump irregularly, often resulting in a fast heart rate and symptoms of irregular pounding and fluttering. There are many risk factors predisposing to AF, however, the cause cannot always be easily determined. Additionally, not all AF patients experience symptoms and consequently, this abnormal rhythm may go undetected and may be discovered accidentally. This is detrimental to patients, as untreated AF patients are at an increased risk of stroke. Patients that are suspected of having AF are referred for an ultrasound scan of the heart (echocardiogram). It is expected to see structural changes to the heart's chambers. However, structural and electrical changes of the heart may be the cause of AF but may also be a result of AF, resulting in a chicken and egg situation. It may be possible that a different type of measurement can be used during an echocardiogram to detect subtle changes in heart muscle patterns. This measurement may then serve to be an early predictor of AF. This would be determined by comparing the patterns in patients with a normal, regular rhythm to those with AF. Potential candidates are initially screened based on their echocardiogram referral. If deemed suitable for this study, the study process is explained to the patient and written informed consent is invited and received. The echocardiogram will be performed as normal with a focus on the area and volume measurements taken of one of the top chambers of the heart. An additional measurement will be taken to observe any subtle changes in the arrangement of heart cells within this same heart chamber. These measurements can be compared to each other to establish any relationship as well as compared to patients with and without AF.
