Filter by:The primary objectives of this trial are: 1. Efficacy evaluation of amlodipine folic acid tablets: To assess the effects of amlodipine folic acid tablets 5.8 mg (5 mg amlodipine + 0.8 mg folic acid)versus amlodipine tablets 5 mg in preventing all-cause stroke in cerebral small vascular disease (CSVD) patients with hypertension and elevated homocysteine (Hcy) level. 2. Intensive Antihypertensive Therapy: To assess the effect of intensive antihypertensive therapy (SBP<130 mmHg) versus standard antihypertensive therapy (SBP 130-<140 mmHg) in reducing risk of combined cardio-cerebrovascular events in CSVD patients with hypertension and elevated Hcy level, using two basic anti-hypertensive drugs, amlodipine tablets 5 mg or amlodipine folic acid tablets 5.8 mg.
The purpose of study is to evaluate whether home visit programs are an effective method for HTN and T2DM management as compared to standard of care clinic visits.
Acute blood pressure elevation is a frequent problem in neurocritical patients. Its effective management is challenging and must avoid significant decreases of blood pressure leading to lower cerebral perfusion pressure worsening ischemia and elevations probably associated with bleeding, rebleeding or hematoma expansion associated with poor prognosis
In this prospective study, the investigators will implement a systematic assessment of adherence to diuretics in a cohort of patients with precapillary pulmonary hypertension. This study is designed to: - determine the overall adherence rates for diuretic regimen - determine the determinants of non-adherence to diuretics - assess the risk of PH worsening occurrence in the non-adhesion group
The purpose of this study is to evaluate the effect of macitentan on hemodynamic measures at Week 24 in pediatric populations.
The purpose of this study is to investigate the effect of bariatric surgery on cardiac function assessed by echocardiography in patients with hypertension.
The study is conducted in the affiliated hospital of Qinghai University .Patients in the department of Critical Care Medicine and Emergency Intensive Care Unit will be eligible for inclusion if they meet the Berlin criteria.Two researchers assess pulmonary artery pressure and right heart function of patients who are enrolled.
This is a randomized controlled trial with 72 patients with hypertension examining the effects on blood pressure of sodium restriction and whether the blood analysis Salt-blood test is associated to a decrease in blood pressure. Patients will be randomized 2:1 to either sodium restriction or usual diet for 4 weeks. Baseline measures will be done before intervention and outcome measures after the 4 weeks.
1. Study name: Blood Pressure and Lipids Reduction in High Risk Elderly Patients with Isolated Systolic Hypertension. 2. Medicine: amlodipine/atorvastatin tablet (5mg/10mg) and amlodipine (5mg). 3. Rationale: Because of its extremely high prevalence in older adults, hypertension is a leading cause of preventable morbidity and mortality. Both SBP and DBP increase linearly up to the fifth or sixth decade of life, after which DBP gradually decreases while SBP continues to rise. Thus, isolated systolic hypertension (ISH) is the predominant form of hypertension in older persons. But there's still no evidence whether elderly ISH patients would benefit from blood pressure and lipid lowering therapy. 4. Objective: To demonstrate that blood pressure and lipid lowering therapy is effective and safe in elderly ISH patients. 5. Study design: This is a 12-month prospective, randomized, active-controlled, apen-label, multi-center study, with three treatment groups: amlodipine/atorvastatin (5mg/10mg tablet); amlodipine (5mg tablet) and lifestyle intervention. 6. Study population: Men or women aged between 65 and 79 years will be screened for hypertension. Eligible patients should be untreated patients with isolated systolic hypertension (clinic systolic blood pressure ≥ 130 and < 150mmHg), and diastolic blood pressure <80 mmHg). Patients should have abilities to understand the study requirements and provide informed consent. 7. Randomization and treatment: After screening period by centers, eligible patients will be randomly divided into 3 groups, taking one pill of amlodipine/atorvastatin (5mg/10mg tablet) or amlodipine (5mg tablet) or lifestyle intervention only. 8. Follow-up: After meeting the inclusion criteria, there will be 2-week screening period. Clinic blood pressure, ambulatory blood pressure, home blood pressure, electrocardiography, concomitant medication records and adverse event records will be collected at randomization period. Then patients will be randomly assigned into amlodipine/atorvastatin group and amlodipine group and lifestyle only group. The treatment will be observed for 12 months. There will be 6 visiting points in the treatment period, which will be the 1st month, 2nd month, 3rd month, 6th month, 9th month and 12th month. 9. Sample size: A total of 480 patients should be enrolled in total. 10. Timeline: After obtaining the approval of Ethics Committee of Ruijin Hospital in October 2021, recruitment will start. Patients enrollment and follow-up will be performed between January 2022 to December 2023.
Background: Emerging data favors aortic blood pressure (BP) over brachial cuff BP in predicting CV and renal complications, as this BP directly impacts the heart, brain and kidneys. In parallel, central BP measuring devices have been developed that are more accurate towards aortic BP and easy to use without training. In no other condition than advanced chronic kidney disease (CKD) is BP control as important, since undertreatment is associated with adverse CV events and progression towards end-stage kidney disease (ESKD), while overtreatment similarly leads to adverse CV events and injurious falls but also acute kidney injury which can precipitate ESKD. To this day, standard BP management relies on brachial cuff BP, which is an imprecise surrogate marker of aortic BP, more so in the advanced CKD population. Considering that these patients have a high risk of CV morbidity and mortality and is a group where brachial BP may be the least reliable, it can be beneficial to manage hypertension in this population using central BP measurements. With the development of affordable and easy to use central BP devices, routine use of central BP in hypertension would now become a reality. However, the superiority of central BP to traditional brachial cuff BP in regard to clinical outcomes will first need to be demonstrated. Objectives: To demonstrate that targeting central BP in advanced CKD patients as opposed to brachial cuff BP is feasible and results in lower arterial stiffness after 12 months of follow-up. Methods: The CENTRAL-CKD trial is an investigator-initiated prospective parallel-group 1:1 randomized double-blinded multicenter pragmatic pilot trial. Patients with CKD stages 4 and 5 (n=116) will be randomized to either a central systolic BP target < 130 mmHg (intervention) or brachial systolic BP target < 130 mmHg (standard care). Central and brachial BP will be concomitantly measured, with treating physicians, patients and investigators blinded towards allocation. As this trial is of a pragmatic design, all other aspects of BP and CKD management, including anti-hypertensive treatment-related decisions, diastolic BP targets, and clinical and laboratory follow-ups will be at the discretion of the attending Nephrologist. The primary outcomes include feasibility of large-scale trial using prespecified criteria and aortic stiffness (carotid-femoral pulse wave velocity) at 12 months. Other cardiovascular, renal, quality of life and safety outcomes will be evaluated. Importance: CENTRAL-CKD is designed as a pilot trial aimed at providing the framework and justification to proceed to a large-scale trial with adequate power to detect the impact of the proposed intervention on clinically important outcomes.
