The aim of this study is to evaluate whether the use of a commercially available standardized olive extract (Tensiofytol) and a commercially available combination preparation (Cholesfytol NG) by individuals with metabolic syndrome Leads to a clinically relevant reduction of blood pressure on the short term, Leads to a clinically relevant reduction of cholesterol levels, especially LDL, Leads to a change in oxidative stress biomarkers. Participants will be stratified by sex and menopausal status before randomization to one of the three treatments for 8 weeks: Tensiofytol: 100 mg oleuropein and 20 mg hydroxytyrosol per day Cholesfytol NG: 2.9 mg monacoline K and 10 mg hydroxytyrosol per day Placebo All treatments have an identical shape and color and should be used in the same way (oral intake; 3 capsules/day during dinner). No dietary instructions are given and participants are asked not to change their dietary habits, nor to start other therapies (medication, supplements, slimming diets, extra physical activity, etc.) during their study period. Standardized questionnaires are used to obtain information on demographics, dietary habits and side effects. At baseline and after 8 weeks, 27 ml blood is drawn for various biological analyses, and blood pressure, BMI and waist circumference are measured.

This is a randomized controlled trial to evaluate personal protective aids (air purifier and N95) as a therapeutic measure in people with hypertension and diabetes exposed to high levels of PM2.5 in India.

The pulmonary hypertension is a disease, which tends to a progredient right heart failure. Although there was a large progress in development of medical therapy, the quality of life, the physical efficiency and the prognosis of the patients are still limited. The aim of the study is to examine the influence of physical training to clinical and molecular parameter.

Objectives: To examine the feasibility of conducting night-time home blood pressure(BP) monitoring (during sleep) and titration of medications in the evening. This will provide data for sample size calculation for the main trial, which will examine whether night-time BP is a better target than conventional daytime BP for hypertension management. Hypothesis to be tested: night-time home BP monitoring(HBPM) and evening drug titration are acceptable to patients; and future main trial is feasible in terms of recruitment/dropout rate/medication adherence. Design and subjects: This pilot randomized-controlled trial will recruit 78 patients with nocturnal hypertension (asleep systolic BP 120mmHg on ambulatory blood pressure monitoring(ABPM)). They will be allocated in 1:1 ratio to have their medication titrated in the evening according to night HBPM (Experimental group) or in the morning according to daytime HBPM (control group) respectively. Instruments: ABPM/HBPM. Interventions: titration of the dose(s) of anti-hypertensive medications in the evening according to night HBPM (experimental group) and in the morning according to daytime HBPM (control group) every 4 weeks. Main outcome measures: ABPM at baseline and at 6 months Data analysis and expected results: The rate of recruitment/dropout and adherence to night HBPM will be presented. The feasibility of HBPM will be assessed by the patients' adherence to HBPM and by patients' interviews. ANCOVA will be used to evaluate whether titration of medication can normalize BP levels. We expect patients to have a high adherence rate and that titration of evening doses of medications will better improve night-time BP on ABPM.

Study name: The Effect of Nitrendipine/Atenolol Combination on Blood Pressure Variability. Medicine: Nitrendipine/Atenolol; Nitrendipine; Atenolol. 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. Objective: To evaluate the effect of nitrendipine/atenolol on blood pressure variability of patients with Grade 1 hypertension compared with nitrendipine or atenolol monotherapy. 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). Study population: Men and Women aged 30-65 years (n=32) meeting the inclusion/exclusion criteria. 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. Follow up: 14 weeks. Sample size: a total of 32 patients should be enrolled. 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 is an open-label, single-armed, prospective single-centre clinical study to evaluate the effect of riociguat on right heart size and function in patients with manifest PAH and CTEPH.

Study name: Prospective Comparison of Angiotensin receptor neprilysin inhibitor (ARNI) with Amlodipine on ventricular remodeling in hypertension and left ventricular hypertrophy. Medicine: sacubitril/valsartan (ARNI, 200mg tablet) and the matching placebo; amlodipine (5mg tablet) and the matching placebo. 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. Objective: to demonstrate the superior efficacy of ARNI on improvement of LVH and blood pressure control compared with amlodipine in hypertension patients with LVH. 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). 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. 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. 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. Sample size: 120 patients in total. 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.

The investigators have developed self-help booklets specifically for adults with PH who are experiencing difficulties with depression. The self-help booklets are based on a type of psychological treatment called Cognitive Behavioural Therapy or CBT for short. CBT looks at the way people think and what they do, and how this affects their mood. It involves making changes to thoughts and behaviours. CBT can help people develop more helpful ways of coping with depression. CBT is one of the most effective therapies for depression, this means it works well. There are four booklets that participants will work though weekly in their own time and at home. The aim of this study is to test whether the self-help booklets are helpful in reducing depression in people with pulmonary hypertension. Those taking part will be asked to complete a series of questions asking about themselves including whether they are experiencing any difficulties such as depression and anxiety. They will then be allocated at random to one of two groups. Group one will receive the self-help booklets, called the intervention group. Group two, or the wait list group, will receive the intervention at a later date if it is found to be helpful. Having two groups is very important as it will allow us to see whether benefits associated with taking part in the project was because of the self-help booklets or something else. Participants in group one will also be contacted partway through the intervention to ask about their experiences of taking part. Both groups will be asked to complete a series of questionnaires four weeks later and then again in one month. Participants in group one will be contacted again to find out more about their experiences of the project.
