Filter by:The goal of this observational study is to apply Artificial Intelligence (AI) and machine learning technology to the resting 12-lead electrocardiogram (ECG) and assess whether it can assist doctors in the early diagnosis of Pulmonary Hypertension (PH). Early and accurate diagnosis is an important step for patients with PH. It helps provide effective treatments early which improve prognosis and quality of life. The main questions our study aims to answer are: 1. Can AI technology in the 12-lead ECG accurately predict the presence of PH? 2. Can AI technology in the 12-lead ECG identify specific sub-types of PH? 3. Can AI technology in the 12-lead ECG predict mortality in patients with PH? In this study, the investigators will recruit 12-lead ECGs from consenting participants who have undergone Right heart Catheterisation (RHC) as part of their routine clinical care. AI technology will be applied to these ECGs to assess whether automated technology can predict the presence of PH and it's associated sub-types.
Hypertension is the most prevalent risk factor and the third leading cause of death worldwide, responsible for an increase in cardiac events. International guidelines on cardiology and hypertension recommend the practice of regular physical exercise for the control and treatment of this disease. The main objective of the study will be to determine the effect of a Multicomponent Training programme versus a Cardiovascular Training programme on blood pressure levels in hypertensive adults. The work methodology will consist of a controlled, randomised, longitudinal and prospective clinical trial, with several simultaneous study branches; on the one hand, the interventions with Multicomponent Training; on the other hand, the interventions with Cardiovascular Training; and, finally, a control group. The sample will be composed of 75 adult hypertensive subjects, including men and women, divided into groups of 25 people, two intervention groups and one control group. The inclusion criteria will be adult subjects, aged 40-65 years, with controlled arterial hypertension and sedentary. Exclusion criteria will be pregnant women and hypertensive patients with serious diseases that prevent the safe practice of physical exercise. The intervention will last 12 weeks and training will be 2 days per week, 60 minutes per session. The variables of the pre-post intervention study will be haemodynamic parameters; body composition, abdominal perimeter, general and manual strength, cardiorespiratory capacity, lipid profile and glucose.
This is a longitudinal study which we plan to examine the link between personality traits, burnout, and hypertension in bank employees in South-eastern Nigeria
The goal of this clinical trial is to compare a new model of care that uses cellular-enabled home blood pressure (BP) telemonitoring and combines it with team-based BP control using a pharmacist to help manage BP medications and to give patients advice on diet and exercise, to an enhanced usual care group that only receives the monitoring device and basic instructions, in individuals with a history of uncontrolled hypertension. The main question[s] it aims to answer are: 1. Among patients with a history of uncontrolled hypertension, evaluate the impact of team-based care using technology-enabled monitoring on improving goal-directed systolic blood pressure (SBP) levels relative to enhanced usual care (primary). 2. Assess the potential for heterogeneity of treatment effects by race, age, sex, and social deprivation index (secondary). 3. Examine the impact of the intervention on hypertension self-efficacy, medication adherence, timeliness of medication change, satisfaction with care, adoption of home BP monitoring, and the change in mean BP in diverse patients, many of whom have adverse social determinants of health (SDOH) (secondary/exploratory). Both groups will be asked to check their BP at home using a cellular-enabled home BP monitoring device that's provided. Patients in the Technology enabled Team Care (TTC) intervention group will have regular phone calls from a clinically trained and experienced pharmacist that works with their doctor/provider and who has reviewed their home BP readings. This pharmacist will help them adjust their medicines, provide brief nutrition and physical activity advice, and may refer them for help with any social challenges (not enough proper food, transportation problems, etc.) that they may be experiencing. An enhanced usual care group will serve as the comparison group and will receive the BP cuff monitoring device and basic instructions but will not receive ongoing monitoring or team care as described above. Researchers will compare the effect of the TTC intervention model to enhanced usual care to assess the impact on SBP levels at 6 and 12 months follow-up, as well as on a variety of patient-reported outcomes.
Exercise is of great importance in the treatment of hypertension, which is expressed as a very serious disease, the prevalence of which is increasing day by day in the world and can cause many complications that are common in society. Exercise methods effective on carotid intima-media thickness, skeletal muscle architecture, and strength, which are important markers of hypertension-related organ damage, remain unclear. Strengthening exercises draw attention as an important approach in the control of hypertension. In order for strengthening exercises to be effective in the rehabilitation of hypertension, moderate and high-intensity exercises are recommended. New exercise approach strategies are gaining importance in order to enable resistance exercise training and to increase muscle mass and strength in the elderly who have a limitation for the recommended exercise intensity, in patients with hypertension, and in people with various diseases in which the cardiovascular system is affected. Whole body vibration (TVV) applications, which have no side effects reported as the current example of these exercise approaches, attract attention. Many positive effects occur on the cardiovascular system with the short-term and low-effort application of TVV exercise approaches, which are frequently used in routine rehabilitation practices. However, when the literature is examined, the effects of these exercise approaches on carotid intima-media thickness, which is one of the main markers of hypertension-related organ damage, are unclear. In addition, the effects of hypertension on quadriceps muscle architecture, which are expected to be adversely affected as a result of affecting autophagy regulation in skeletal muscle and causing decreased muscle capillarization, remain unclear. In addition, there is insufficient data on the effectiveness of strengthening exercises and TVV exercises on hemodynamic responses and quadriceps muscle strength in hypertensive patients. It will shed light on the determination of the exercise approach that is most effective on the muscle architecture, hemodynamic responses and carotid intima-media thickness of hypertensive patients and that can show these effects without overloading the cardiovascular system.
The objective of this study is to test the feasibility of using behavioral economic interventions (gamification with social incentives) to increase physical activity after hospital discharge to reduce incident mobility disability among older adults.
Pulmonary hypertension is a common clinical syndrome, which seriously affects the quality of life and survival of patients. Pulmonary hypertension (PH) is defined as an increase in mean pulmonary arterial pressure (mPAP) to ≥20 mmHg at rest as measured invasively by right heart catheterisation (RHC). Pulmonary hypertension can be divided into five types, among which pulmonary hypertension caused by chronic pulmonary diseases and/or hypoxia is called Group 3 pulmonary hypertension, which is the most important factor of pulmonary heart disease. The drugs currently used to treat patients with PAH (prostanoids, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, sGC stimulators) have not been sufficiently investigated in Group 3 PH, except indirect treatment methods such as improving hypoxia and controlling infection. Recombinant human brain natriuretic peptide (rhBNP) is a biological agent with a molecular weight of 3664Da synthesized by DNA technology. It is availble in China. It has many functions such as diuresis, vasodilation, inhibition of renin-angiotensin-aldosterone and sympathetic nervous systems, etc. RhBNP has been suggested in patients with acute myocardial infarction and congestive heart failure. In view of the dilating effect of rhBNP on pulmonary vessels, it is speculated that rhBNP may reduce type 3 pulmonary hypertension. Based on this hypothesis, we conducted a preliminary clinical trial. The results showed that, compared with the placebo group, after rhBNP was continuously pumped for 24 hours, the pulmonary artery hemodynamic indexes continuously monitored by Swan-Ganz catheter were significantly improved. In view of the pharmacological effect of rhBNP and our previous clinical trial results, this study intends to conduct a prospective, multicenter, placebo-controlled, double-blind clinical trial to evaluate the efficacy and safety of rhBNP in the treatment of patients with group 3 pulmonary hypertension.
The electronic health record contains vast amounts of cardiovascular data, including potential clues that an individual may have unrecognized cardiac conditions. One important example is the finding of thickened heart muscle -- known as left ventricular hypertrophy (LVH) -- on echocardiograms (heart ultrasounds). If the underlying cause of LVH is untreated, individuals are at an increased risk of developing more severe pathology. As the most common cause of LVH, hypertension and its downstream consequences account for more cardiovascular deaths than any other modifiable risk factor. Critically, many individuals have signs of cardiac damage from hypertension before it is diagnosed or treated. Despite this evidence, there are often gaps in healthcare delivery that contribute to substandard recognition and treatment. Thus, there is an urgent need to validate alternative cost-effective screening and intervention strategies. Echocardiograms are ordered by many specialties and for numerous indications. Even when LVH is reported, the finding may be underappreciated and not prompt further evaluation. Whether data from prior echocardiograms can be harnessed to improve patient care through a centralized intervention is unknown. Accordingly, the goal of this randomized pragmatic clinical trial is to study the impact of a centralized clinical support pathway on the diagnosis and treatment of hypertension and the recognition of LVH-associated diseases in individuals with evidence of thickened heart muscle on previously performed echocardiograms.
Elevated aldosterone causes moderate to severe increase in blood pressure, and leads to various target organ damage including cardiovascular ones. Aldosterone has been considered one of the important risk factors for cardiovascular and cerebrovascular diseases. Currently, the use of mineralocorticoid receptor antagonists(MRA) has been proven to reduce blood pressure levels, but long-term prognostic data are lacking in hypertensive patients. Therefore, the purpose of this clinical trial is to assess the effect of MRA on cardiovascular disease in patients with Hypertension and Hyperaldosteronemia.
Background: Hypertension is a public health problem; the World Health Organization (WHO) estimates that more than 1280 million people suffer it. The treatment of said condition is pharmacological and non-pharmacological. Physical activity is part of the treatment, but unfortunately few adults can be classified as physically active. There is evidence that performing physical exercise reduces systolic blood pressure by up to 5 mm Hg, which has associated with reduced heart disease by up to 9%, ictus up to 14% and all-cause mortality by 4%. Lifestyle changing interventions, among them promoting exercise marked by a theory of behavior change, have shown positive results. Objective: To evaluate the effect of an intervention promoting the performance of physical exercise, with specific recommendations, based on the Transtheoretical Model, on systolic blood pressure and on the amount of exercise performed (minutes/week) in patients with hypertension aged 40 to 70 years, users of primary care in the Mexican Institute for Social Security (IMSS) in Aguascalientes. Material and methods: Randomized clinical trial, in which 442 patients with hypertension will participate. The control group will receive conventional care and recommendations for physical exercise and diet. The intervention group, in addition, will attend 6 workshops, one a month, which will promote performing physical exercise, with access given to videos of physical exercise routines, designed to gradually increase the exercise performed. At the start and end of the study, blood pressure, anthropometric measurements will be taken, through a questionnaire asking about sociodemographic data, performance of physical exercise, psychosocial factors regarding physical exercise, diet and adherence to pharmacological treatment. The characteristics of the study population by group will be described, and changes between baseline and final measurements compared, intra and intergroup, in the systolic blood pressure and minutes/week of physical exercise.
