Filter by:1. Study name: The Effect of Nitrendipine/Atenolol Combination on Blood Pressure Variability. 2. Medicine: Nitrendipine/Atenolol; Nitrendipine; Atenolol. 3. Rationale: Blood pressure variability correlates with cardiovascular events and target-organ damage in hypertensive patients. Nitrendipine/Atenolol has obvious advantages in reducing blood pressure variability in hypertensive rats, but the effect of this combination on hypertensive patients is still unknown. 4. Objective: To evaluate the effect of nitrendipine/atenolol on blood pressure variability of patients with Grade 1 hypertension compared with nitrendipine or atenolol monotherapy. 5. Study design: This study is a cross-over, randomized, controlled clinical trial with two equally sized treatment groups: Nitrendipine/Atenolol (5mg/10mg); Nitrendipine (10mg) or atenolol (25mg). 6. Study population: Men and Women aged 30-65 years (n=32) meeting the inclusion/exclusion criteria. 7. Randomization and cross-over design: Eligible patients will be randomly divided into two groups. Half of patients will take nitrendipine/atenolol (5/10mg) once daily for 6 weeks first, and then evenly turn into nitrendipine (10mg) or atenolol (25mg) once daily for 6 weeks. Another half of patients will evenly take nitrendipine (10mg) or atenolol (25mg) first, and turn into nitrendipine/atenolol (5/10mg) next. 8. Follow up: 14 weeks. 9. Sample size: a total of 32 patients should be enrolled. 10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in April 2021, recruitment will start. Patients enrollment and follow-up will be performed between June 2021 to June 2022.
1. Study name: Prospective Comparison of Angiotensin receptor neprilysin inhibitor (ARNI) with Amlodipine on ventricular remodeling in hypertension and left ventricular hypertrophy. 2. Medicine: sacubitril/valsartan (ARNI, 200mg tablet) and the matching placebo; amlodipine (5mg tablet) and the matching placebo. 3. Rationale: according to the results of previous clinical studies, ARNI has obvious advantages in improving cardiac remodeling and reducing blood pressure. However, there is no evidence to demonstrate the efficacy of ARNI in reducing blood pressure and improving ventricular remodeling in hypertension patients with left ventricular hypertrophy (LVH) compared with calcium channel blockers. 4. Objective: to demonstrate the superior efficacy of ARNI on improvement of LVH and blood pressure control compared with amlodipine in hypertension patients with LVH. 5. Study design: This study This is a 24-week prospective, randomized, active-controlled, double-blind, multi-center study, with two equally sized treatment groups: sacubitril/valsartan (200mg tablet); amlodipine (5mg tablet). 6. Study population: men or women aged over 18 years; Untreated patients or patients with taking single antihypertensive drugs; Essential mild to moderate hypertension; Echocardiographic diagnosis of LVH. 7. Randomization and treatment: Eligible patients will be randomly divided into 2 groups, taking one pill of sacubitril/valsartan (200mg tablet) + one pill of matching placebo of amlodipine daily, or one pill of amlodipine (5 mg/tablet) + one pill of matching placebo of sacubitril/valsartan daily. 8. Follow up: after meeting the inclusion criteria, there will be 2-week placebo run-in. Then patients will be randomly assigned into ARNI group and amlodipine group. There will be 5 visiting points in the treatment period, which will be the 4th week, 8th week, 12th week, 18th week and 24th week. 9. Sample size: 120 patients in total. 10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in April 2021, recruitment will start. Patients enrollment and follow-up will be performed between June 2021 to June 2022.
This will be a single center, Phase I/IB, randomized, double-blind, placebo-controlled, sequential SAD/MAD/FE study, with a patients arm. The study will be divided into three parts: Part A: SAD cohorts, with FE evaluation Part B: MAD cohorts with healthy volunteers Part C: MAD cohorts including naïve patients with mild to moderate hypertension and low cardiovascular risk The three parts will be completed sequentially or with partial overlapping.
This prospective observational trial includes women with high risk pregnancies complicated with hyperglycemia in pregnancy and excessive body weight. The participants are enrolled when pregnant and monitored throughout pregnancy and delivery until the offspring is 6 months old. This research addresses the question which risk factors for non-communicable disorders such as hypertension, obesity, type 2 diabetes for a woman and her offspring can be detected during pregnancy and in early childhood.
The objective of the study is to evaluate the safety of multi-organ denervation using the Integrated Radio Frequency (iRF) Denervation System. and to understand any potential improvement in hypertension and glycemic control.
The purpose of this study to investigate the effects of colchicine on measures of vascular and cardiac function in patients with hypertension.
Black garlic contains a series of allyl-sulfur compounds with the ability to modulate nitric oxide synthetase, angiotensin-converting enzyme system, and endothelial activation, which together could help better control blood pressure. The main objective of this study is to evaluate the effect on blood pressure and endothelial health of a daily intake of a black garlic supplement named ABG (registered mark), which has a higher concentration of black garlic bioactive compounds, in people with moderate hypertension.
More than 80% of individuals with chronic kidney disease have concomitant hypertension and the majority fail to achieve blood pressure control <130/80 mmHg, leading to high risk of cardiovascular diseases and end-stage kidney disease. A stepwise combination of lifestyle modifications and drug therapy is recommended to lower blood pressure; however, adherence to time-intensive lifestyle interventions such as aerobic exercise in patients with chronic kidney disease is poor. This clinical trial seeks to establish the efficacy of high-resistance inspiratory muscle strength training, a novel time-efficient lifestyle intervention, for lowering systolic blood pressure and improving endothelial function in midlife and older adults with moderate-to-severe chronic kidney disease and inadequately controlled hypertension, and to use innovate translational assessments to understand the mechanisms involved.
This research study is being done to find out if exercise therapy can help improve the heart function, overall health, and quality of life of patients with pulmonary hypertension caused by heart failure.
In 2017, the American College of Cardiology and the American Heart Association changed the diagnostic criteria for hypertension in non-pregnant adults. The parameters for the diagnosis of stage 1 hypertension were revised from a systolic blood pressure (BP) of 140 to 130 mm Hg and a diastolic BP of 90 to 80 mm Hg. Based on new criteria, stage 1 hypertension is associated with a 2-3 fold increased risk of preeclampsia. There are no data regarding prevention of preeclampsia in women with stage 1 hypertension. Low-dose aspirin has been used during pregnancy to prevent preeclampsia for women at high-risk for preeclampsia. Although the precise mechanism remains uncertain, it is possible that low-dose aspirin improves placental perfusion, which results in a decreased rate of preeclampsia. A study that examines the effect of low-dose aspirin on placenta vasculature and tissue elastography by using novel ultrasound tools would be useful. The 2017 Aspirin for Evidence-Based Preeclampsia Prevention trial compared 150 mg aspirin with placebo in women at high-risk of preeclampsia based on a first-trimester screening. They found a significant decrease in the rate of preterm preeclampsia (4.3% vs. 1.6%; P <0.01). Since this study used the screening algorithm including first-trimester serum markers and uterine artery Doppler, the generalizability in the U.S. women with stage 1 hypertension is limited. Our pilot study will examine 1) the effect of low-dose aspirin 81 mg in women with stage 1 hypertension on placental vasculature and shear-wave elastography; 2) the rate of preterm preeclampsia in women with stage 1 hypertension in a control group and in pregnancies treated with low-dose aspirin 81 mg; 3) feasibility of conducting a larger multicenter randomized controlled trial on this subject.
