Filter by:This study aims to evaluate the comparative risk of dementia/Alzheimer's disease onset between patients treated with medications that target specific metabolic pathways and patients treated with alternative medications for the same indication.
To correlate fetal Pulmonary artery Doppler parameters with neonatal outcome in patients diagnosed with hypertensive disorders of pregnancy.
Successfully communicating cardiovascular risk to patients is essential for achieving compliance to medication and lifestyle changes. An intuitive way to translate cardiovascular risk is to present a Heart Age; an ECG-based age-estimation from ECG changes which can be contrasted to a patient's chronological age. In this pilot study, the feasibility of a randomized controlled study (RCT) in which hypertensive patients in primary care will receive information about their ECG-based Heart Age in addition to standard care, or standard care alone, will be assessed, in preparation for a larger RCT.
According to international guidelines, Hepatic Venous Pressure Gradient is the gold standard technique for portal hypertension measurement, but it is invasive and poorly available. Currently, surveillance of oesophageal/gastric varices is performed by upper gastrointestinal endoscopy. More recently, non-invasive tools to estimate portal hypertension have been developed and, among them, ultrasound elastography has been proposed as a technique to stratify patient risk to have portal hypertension. Aim of this study is to evaluate the relationship between ultrasound evaluation (D-CEUS + elastography) and endoscopic parameters predictive of clinically significant portal hypertension in patients with liver cirrhosis.
It is an observational research, conducted at the Cayenne hospital about the future of hypertensive and/or diabetic patients after their follow-up at the Permanent Access to care (PASS). The PASS is a medico-social structure that allows access to medical monitoring and support towards common law. The main objective of the study is to evaluate the use of the common law system by these patients. Then the goal is to study the relationship between integration into the system and socio-demographic, medical characteristics, and understanding of health monitoring. Data will be collected by guided telephone interviews and the review of medical records.
This project was a facility-based program intervention for People Living with HIV (PLHIV) aged 18 years and above who attended a Care and Treatment Center (CTC) in Dar es Salaam, Tanzania. Clients received preventive, diagnostic, and treatment services for Hypertension (HTN) and Type Two Diabetes Mellitus (T2DM). The primary health outcomes were all-cause mortality, disease-specific morbidity, HTN, and T2DM control rates. Secondary outcomes included access to care, retention in care adherence, and quality of care. Results obtained can be used to strengthen Non-Communicable Diseases (NCDs) care delivery in HIV/AIDS care in CTC in Tanzania.
The purpose of this research study is to measure cerebrospinal fluid (CSF) clearance in subjects with and without high blood pressure. CSF cushions the brain from impact and carries waste products from the brain to the bloodstream. This process is known as clearance. Impaired removal of proteins from the aging brain causes their buildup and may contribute to an increased risk for Alzheimer's disease. It is also suspected that clearance may be related to the health of vessels carrying the blood throughout the brain. It is known that high blood pressure damages blood vessels and thus may impair clearance. In this project we will examine if having high blood pressure is related to impaired brain clearance and whether treating high blood pressure improves clearance and reduces buildup of Alzheimer's disease-related proteins. Participants will be asked to undergo a medical examination, testing of memory, brain imaging (both magnetic resonance and positron emission tomography, and spinal tap at the beginning of the study and 1 -2 years later.
There is a lack of effective treatments for chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension. Previous studies have found that inhaled nitric oxide (iNO) can reduce pulmonary artery pressure and improve exercise capacity in COPD with pulmonary hypertension patients. However, the specific mechanism is unclear. The study aims to evaluate pulmonary ventilation/perfusion, pulmonary artery pressure, oxygenation, symptoms and quality of life in COPD with pulmonary hypertension patients after short-term treatment with iNO. Observing a series of pathophysiological changes caused by the treatment of pulmonary hypertension with iNO in COPD, the investigators hope to provide new theoretical basis and research ideas.
Patients with clinically significant portal hypertension allocated to implantation of a transjugular intrahepatic portosystemic shunt (TIPS) at the Department of Medicine II of the University Medical Center Freiburg, Germany will be offered to participate in this prospective observational trial. Clinical and laboratory as well as outcome parameters will be assessed before and within the first 12 months after TIPS implantation following a regular follow-up schedule with clinical visits at the University Medical Center Freiburg. During follow-up visits, serum/plasma samples and peripheral blood mononuclear cells (PBMC) are collected and stored in a associated biobank.
Out-of-office blood pressure (BP) measurement by means of ambulatory BP monitoring (ABPM) or home BP monitoring (HBPM) is recommended for the diagnosis and management of hypertension in the latest guidelines. Ambulatory BP values are more strongly associated with target organ damage and cardiovascular (CVD) events than office values. In particular, nocturnal blood pressure level and reduction of BP during the night (dipping) have been recognised as predictors of cardiovascular complications. However, in current clinical practice, these parameters are derived from ABPM. HBPM represents an inexpensive alternative to ABPM, is preferred by patients and provides a more realistic assessment of BP during an individual's daily life. However, until recently, HBPM did not offer the possibility to measure nocturnal BP or dipping. The development and validation of new BP devices, such as the NightView (OMRON Healthcare, HEM9601T-E3) could overcome this limitation, offering the possibility of home night-time BP measurements with minimal sleep disturbance. On the other hand the use of wearable devices such as HeartGuide (OMRON Healthcare, HEM-6411T-MAE) could provide BP values in daily life conditions. Compared with conventional HBP, typically measured in resting conditions at home, values obtained with wearable devices might be closer to daytime ABP values. Combining nocturnal HBP, with daytime BP from wearable device could therefore allow the estimation of dipping status comparable with that provided by ABPM. In order to compare HBP-derived dipping estimate with the gold standard ABPM-derived value, it is aimed to enrol patients with hypertension, assess their blood pressure profile with ABPM and provide them with both NightView and HeartGuide devices for 7 days. Then diurnal and nocturnal BP and dipping derived from standard 24-hour ABPM will be compared and the combination of NightView/HeartGuide in order to understand whether the latter can offer a reliable assessment of 24h BP pattern. For a better phenotypization of nocturnal BP and dipping status the following determinants of nocturnal BP and dipping status will be also investigated: sleep quality, sleep duration, the presence of sleep disorders, salt consumption, catecholamine phenotype. This study will offer the unique opportunity to understand whether such new HBP devices can be offered in alternative to ABPM in the assessment of 24h BP profile in patients with hypertension.
