This prospective single-center observational study aims to evaluate the relationship between elevated plasma homocysteine levels and early echocardiographic abnormalities in patients with newly diagnosed essential hypertension. Adult patients diagnosed with essential hypertension within the previous 6 months will undergo clinical assessment, ambulatory blood pressure monitoring, electrocardiography, laboratory testing, and comprehensive transthoracic echocardiography including diastolic function assessment and strain analysis when image quality is adequate. Participants will be classified according to plasma homocysteine level using, and patients with elevated and normal homocysteine levels will be compared with respect to diastolic dysfunction and left ventricular and left atrial global longitudinal strain parameters. Clinical, laboratory, and echocardiographic data will also be used to develop a machine-learning based model for prediction of H-type hypertension.

High blood pressure (hypertension) is a leading risk factor for cardiovascular diseases and may contribute to poor health and premature death. The purpose of this research is to learn if a home-based isometric exercise programme combined with lifestyle change advice is a practical and acceptable method for people diagnosed with hypertension to manage their condition. Isometric exercise involves a muscle contraction without movement of the limbs and previous research has shown this may be effective for reducing blood pressure. Therefore, this study will explore the experiences, thoughts, attitudes, and barriers to participation. It will also examine the effect the isometric exercise has on blood pressure. Participants will undertake an isometric exercise programme using a wall squat position, 3 times per week, for 12 weeks. The exercise sessions will be completed at home with remote online supervision by an exercise professional. Lifestyle change advice will given in line with current guidelines to promote healthy behaviours to reduce high blood pressure. After 12 weeks, participants will be encouraged to continue with the wall squat exercise for a further 12-weeks unsupervised. Throughout the study, participants' blood pressure and daily activity will be recorded using a smartwatch device. Upon completion of the intervention period, participants will be interviewed to gather their views and opinions on the isometric exercise programme. Changes in blood pressure will be evaluated at 12 and 24 weeks. By exploring whether an isometric exercise programme is a feasible and acceptable method for hypertensive people to manage their condition and how this influences blood pressure, this research may aid in the development of a strategy to manage hypertension.

Research Title "Quadruple-Blind Randomized Controlled Trial of the Effect of CPAP on Blood Pressure in Patients with Sleep Apnea" Why are we conducting this study? * Sleep apnea (OSA) is very common, affecting approximately one in every eight adults. It makes it more difficult to control blood pressure. * Continuous Positive Airway Pressure (CPAP) is the preferred treatment, but the effect on blood pressure varies from person to person. * We want to know: Which patients experience the greatest reduction in blood pressure with CPAP? Can adding a little sleep aid medication for those who have trouble sleeping or frequently wake up at night improve the effectiveness of CPAP and lead to better blood pressure control? Who will participate? * 18-70 years old, diagnosed with obstructive sleep apnea, with snoring, gasping, or daytime sleepiness. * High blood pressure or newly diagnosed with mild hypertension, or taking 1-2 blood pressure-lowering medications but not reaching the target. * Able to wear the CPAP mask every night and willing to undergo 3-month follow-up. * Pregnant women, those already using CPAP, those with a history of heart disease/stroke in the last 3 months, those working night shifts ≥ 3 nights/week, or those participating in other intervention trials are not eligible. What will the study do? First, conduct a full-night sleep monitoring and 24-hour blood pressure monitoring to adjust the most suitable CPAP pressure for you. Wear the CPAP mask for ≥ 4 hours every night, for a total of ≥ 21 days per month, for approximately 3 months. If you often wake up at night or have insomnia, you can voluntarily join the "sleep aid medication" group: take trazodone (25-150 mg) or zolpidem (3.75-7.5 mg) before bedtime for 4 weeks. During this period, we will use questionnaires, a small wristwatch (actigraphy), and additional sleep monitoring to observe changes in sleep and blood pressure; we will also draw a small amount of blood and collect urine for routine safety checks. You can withdraw at any time without any penalty and it will not affect your regular medical treatment. Possible benefits * Free comprehensive assessment of sleep and blood pressure, one-on-one guidance from a doctor. * May lead to a reduction in blood pressure and improvement in nighttime sleep quality. * Help future patients like you receive better treatment. Possible discomfort or risks * CPAP: mask pressure marks, dry mouth and nose, feeling of suffocation, bloating; most people's symptoms are relieved after adjusting the humidifier or mask. * Sleep aid medication: next-day drowsiness, dry mouth, dizziness, nausea; rare cases may include persistent penile erection in men (immediate medical consultation required); the risk of dependency for zolpidem after continuous use for 4 weeks is very low, but it still requires monitoring by a doctor. * Check: wearing a blood pressure cuff and sleep monitoring device may cause slight inconvenience during sleep. * If there is any injury related to the study, Anzhen Hospital will provide necessary treatment and compensation in accordance with Chinese laws. Privacy and Costs * Sleep monitoring, dynamic blood pressure, medications, and tests required for the study are all free. * Your name and medical record will only be viewed by researchers and the ethics committee. Personal identity will not be disclosed when the article is published. Contact person * Research Question: Dr. Xie Jiang 010-64456528 (during working days) / 131-6198-5564 (at other times) * Rights and Benefits: Beijing Anzhen Hospital Ethics Committee 010-64456214 Voluntary Decision Whether to participate or not is completely voluntary. You can withdraw at any time without any reason, and it will not affect the medical care you are entitled to.

The goal of this clinical trial is to treat both hypertension and obesity in adults using a food is medicine framework. Participants will be randomized 1:1 to FIM+DASH or usual-care control. The 24-week trial includes a 12-week FIM+DASH intervention followed by a 12-week maintenance period and leverages existing partnerships with community-based organizations for home food delivery and culinary skill-skill building. The main questions it aims to answer are: (1) What is the effect of FIM+DASH vs. usual care control on blood pressure? (2) What is the effect of FIM+DASH vs. usual care control on DASH diet adherence (diet quality), body weight, and waist circumference? (3) How to identify factors associated with the sustainability and scalability of FIM+DASH in real-world settings?
NCT07240831
This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.

Participants in the intervention group will use smart devices to record physiological data, which are automatically uploaded to a cloud-based health management platform. Physicians will review the data monthly and provide personalized consultations and health education. Primary outcomes include anthropometric measures, biochemical indices, electrocardiograms, and self-reported health and sleep quality.
NCT07145710
This study evaluated the effects of raw banana flour (RBF)-enriched muffins on hypertensive patients in Lahore, Pakistan. A total of 34 patients were divided into three groups: a control group and two intervention groups receiving muffins with 35% (C1) or 40% (C2) RBF for 10 weeks. Sensory evaluation showed high acceptability of the 35% RBF muffins, comparable to control muffins. Clinical outcomes indicated that both intervention groups experienced improvements in body weight, BMI, blood pressure, liver enzymes, and lipid profiles, with more pronounced benefits observed in the 40% RBF group. The findings suggest that RBF-enriched muffins, particularly at 40% substitution, can offer functional, nutritional, and clinical benefits for individuals with hypertension.
