Filter by:The study is designed as a prospective randomized, controlled, double-blinded phase II trial to examine the effect of the SGLT2 inhibitor dapagliflozin, in comparison with placebo on cardiovascular outcome parameters in kidney failure patients undergoing replacement therapy with hemodialysis. The primary endpoint is the change (∆) in left ventricular mass indexed to body surface area (LVMi) from baseline to 6 months measured by cardiac magnetic resonance imaging. Null and alternative hypotheses: H0: There is no difference in the ∆ Left Ventricular Mass indexed to BSA after six months of treatment, comparing patients having received the SGLT2-Inhibitor Dapagliflozin versus placebo. H1: There is a difference in the ∆ Left Ventricular Mass indexed to BSA comparing patients having received the SGLT2-Inhibitor Dapagliflozin versus placebo.

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.
Studying the causal roles of components of the renin-angiotensin-aldosterone system (including angiotensin-(1-7) (Ang-(1-7)), angiotensin-converting enzyme 2 (ACE2), Ang II, and ACE), uric acid, and klotho in pediatric hypertension and related target organ injury, including in the heart, kidneys, vasculature, and brain. Recruiting children with a new hypertension diagnosis over a 2-year period from the Hypertension and Pediatric Nephrology Clinics affiliated with Brenner Children's Hospital at Atrium Health Wake Forest Baptist and Atrium Health Levine Children's Hospital. Healthy control participants will be recruited from local general primary care practices. Collecting blood and urine samples to analyze components of the renin-angiotensin-aldosterone system (Ang-(1-7), ACE2, Ang II, ACE), uric acid, and klotho, and measuring blood pressure, heart structure and function, autonomic function, vascular function, and kidney function at baseline, year 1, and year 2. Objectives are to investigate phenotypic and treatment response variability and to causally infer if Ang-(1-7), ACE2, Ang II, ACE, uric acid, and klotho contribute to target organ injury due to hypertension.
Hypothesis/Study question In infants born at less than 29 weeks of estimated gestational age, what are the effects of dexamethasone use on cardiac structure/performance and lung water content? Study objectives To measure effects before and after dexamethasone administration on cardiac structure/performance will be evaluated by using the M-mode technique (Devereux method (25-27) and lung water content will be specifically determined by the degree of water retention in premature lungs assessed by lung ultrasound at the pre specified time points. Methodology / Study design Single center, prospective observational cohort study planning to enroll eligible patients over a period of 12 months
The purpose of this study is to evaluate the effects of empagliflozin on cardiac structure, function and circulating biomarkers in patients with cardiovascular risk factors, but without diabetes. Empagliflozin is an antihyperglycemic agent approved by Health Canada and the FDA for the treatment of type 2 diabetes. Previous post-marketing clinical trials demonstrated a reduction in cardiovascular deaths and heart failure in patients with type 2 diabetes treated with empagliflozin. In the first EMPA-HEART trial, we demonstrated that empagliflozin reduces cardiac mass in patients with type 2 diabetes, as seen through cardiac magnetic resonance imaging (cMRI). Therefore, the aim of this study, EMPA-HEART 2, is to determine whether empagliflozin can similarly impact cardiac structure in patients without diabetes, but with various cardiovascular risk factors.
Left ventricular hypertrophy (LVH) is the most common result of the heart trying to pump blood against the high afterload, as in hypertension and aortic stenosis.Although hypertension is the most common cause of LVH, LVH can also be found in athletes and cardiomyopathies or in storage disorders such as amyloidosis. In addition, genetic diseases also play an important role in the pathogenesis of LVH. Fabry disease is another disease that should be considered in patients with left ventricular hypertrophy.Left ventricular hypertrophy is a common and potentially modifiable cardiovascular risk factor that is frequently overlooked in clinical practice.The benefit of combining ECG and echocardiography in the diagnosis of LVH has been demonstrated.Early diagnosis and treatment-related regression of LVH, reduces adverse cardiovascular events and improves survival.Therefore, the investigators planned to perform a retrospective, observational LVH-TR study in order to determine the etiologic causes of LVH, the symptoms presented by the patients, and the effects of patients' demographic characteristics on LVH.
The working hypothesis is that cardiac macrophages specific for the compensated cardiac hypertrophic phase limit the progression toward the decompensated state of heart failure by promoting an inflammatory environment favouring cardiomyocyte survival and preservation of the pump function. The investigators will perform studies in human plasma and monos, cardiac tissues and macrophages to validate this hypothesis.
This is an ongoing, prospective cohort study of children and young adults who are evaluated in the Reversing the Negative Effects of Weight on the Heart (ReNEW) Clinic at Johns Hopkins University. Demographic and clinical data of patients who agree to participate are obtained via chart review and entered into a longitudinal clinic registry.
Cardiovascular disease (CVD) is the major risk factor for death in end stage renal diseases (ESRD). Approximately 80% of ESRD patients have some degrees of left ventricular abnormalities at initiation of dialysis. Carotid intima media thickness (CIMT) has been widely accepted as an useful marker to assess CVD in ESRD children. In addition, cardiac mechanics parameters are used to evaluate cardiac function more precisely. However, measuring CIMT and cardiac mechanics parameters are expensive and difficult to perform as a routine method. Mean platelet volume (MPV) is a hematological index which shows the size of platelets. Uremic state causes inflammatory condition that affects MPV. Previous studies on people with normal renal function have shown that this parameter can also have association with CVD. However the data in children with ESRD is scarce. The aim of this study is to find a simple hematologic marker to use regularly in ESRD children finding patients at risk of CVD. Therefore, we will investigate the relationship between mean platelet volume and CIMT and cardiac mechanic parameters in children with ESRD.
