Primary Hypertension

This randomized controlled trial examines the effects of nurse-led self-acupressure at HT7, LI4, PC6, and EX3 points on blood pressure, stress, and well-being in adults with primary hypertension. Participants are randomized to real acupressure, sham acupressure, or usual care groups for 2 weeks.

Children and adolescents with primary hypertension (high blood pressure without an underlying secondary cause) are at increased risk of cardiovascular disease in adulthood. Recent research suggests that not only the heart and blood vessels, but also the bacteria living in the mouth may play a role in blood pressure regulation. Certain oral bacteria can convert nitrate from food into nitrite and then into nitric oxide, a substance that helps blood vessels relax. If this nitrate-nitrite-nitric oxide pathway is impaired, blood pressure may rise. This study aims to investigate the relationship between oral microbiota, salivary nitric oxide reductase activity and blood pressure in children and adolescents with primary hypertension compared with healthy peers. We will recruit participants aged 10-18 years who have a diagnosis of primary hypertension and an age- and sex-matched control group without hypertension. All participants will undergo a non-invasive oral and dental examination and standardized blood pressure measurements. Saliva samples will be collected to measure pH, flow rate, nitrate and nitrite levels, total protein, lysozyme activity and to analyze the composition of oral bacteria using modern DNA-based techniques. Participants and/or their parents will also complete brief questionnaires about diet and general health. No medication or dietary supplement will be given as part of the study, and no additional blood samples will be taken beyond routine clinical care. The main risk is minimal discomfort related to oral examination and saliva collection. There is no guaranteed direct benefit for participants; however, the results may help us better understand how oral bacteria and salivary nitric oxide pathways are linked to high blood pressure in young people. This knowledge may support the development of new non-invasive strategies for early detection and prevention of hypertension in the future.

This study focuses on individuals with primary hypertension, with the main objective of investigating the effectiveness and safety of high-intensity transcranial alternating current stimulation (Hi-tACS) as a non-invasive, non-pharmacological treatment for hypertension

This study aims to evaluate the bioequivalence and safety of single oral administration of Sacubitril/Valsartan/Amlodipine Tablets (240mg/5mg) versus Sacubitril/Valsartan Calcium Tablets (240mg) combined with Amlodipine Besylate Tablets (5mg) in healthy adult study participants.

This study aims to determine the effects of lavender oil inhalation on anxiety, sleep quality, and blood pressure in patients with primary hypertension. The study is designed as a double-blind randomized controlled trial. The study population consists of patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital. Participants are randomly assigned to an experimental group, which will receive a total of 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine treatment and care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

The goal of this clinical trial is to develop biomarkers composed of multiple OMICs (MOMICs) for prediction of blood pressure response to antihypertensive drugs in the treatment of primary hypertension. The main objectives are: * Primary objective: \- To identify MOMICs biomarkers that predict the response in 24-hour blood pressure to antihypertensive treatment for each treatment group (olmesartan, amlodipine, hydrochlorothiazide, olmesartan/amlodipine) * Secondary objectives: * To identify a MOMICs biomarker that predict the response in night-time blood pressure to anti-hypertensive treatment for each treatment group (olmesartan, amlodipine, hydrochlorothiazide, olmesartan/amlodipine) * To identify MOMICs biomarkers that predict side effects, including changes in QoLof olmesartan, amlodipine and hydrochlorothiazide. * Exploratory objective: * To assess changes in MOMICs biomarkers induced by each drug Participants will undergo three 4-week treatment periods: * Each subject receives 3 out of 4 possible treatments (olmesartan, amlodipine, hydrochlorothiazide, olmesartan/amlodipine). * Before and after each treatment period OMICS measurements and an ABPM are performed. * At the end of each treatment period blood is sampled for drug level testing to assess adherence. * Electrolytes and kidney function are checked 5-7 days after start of each treatment period.

The investigators intend to find a noninvasive method for CB modulation therapy and find a simple and convenient indicator for assessing CB activity. This study was designed to evaluate the safety and efficacy of carotid body modulation therapy in hypertensive patients by external ultrasonic micro-bubble and also identify the association between CB volume and CB activity.
