Filter by:A 2-arm randomized pilot trial aimed at evaluating the effectiveness of a 6-month remote monitoring program for the management of hypertension (HTN). 300 eligible patients will be randomized in a 1:1 ratio into two recruitment arms: A) Control (usual care), or B) Remote monitoring via automated messaging program. The target population are patients at the Penn Family Medicine University City and Westtown primary care practices with baseline poor blood pressure control as indicated by two blood pressures greater than 140/90 within the past twelve month including the most recent measurement and on at least one anti-hypertensive agent.
Efficacy and safety evaluation of tolvaptan in the treatment of patients with right heart failure caused by pulmonary arterial hypertension
Pulmonary hypertension represents a challenging and heterogeneous condition that is associated with high mortality and morbidity if left untreated. Artificial intelligence is used to study and develop theories and methods that simulate and extend human intelligence, which is being applied in fields related to cardiovascular diseases. The study intends to combine multimodal clinical data of patients who undergo right heart catheterization at Fuwai Hospital with artificial intelligence techniques to create programs that can screen and diagnose pulmonary hypertension.
Pulmonary hypertension (PHT) is an oPAP ≥25 mmHg as assessed by right heart catheterization at rest. It is divided into 5 groups according to its etiology and mechanism. The first group is patients with pulmonary arterial hypertension due to various reasons (drugs, connective tissue diseases, etc.). Group 2 is classified as left heart failure, group 3 is due to chronic lung disease and hypoxemia, group 4 is due to pulmonary arterial obstruction (most commonly CTEPH), and group 5 is patients with pulmonary hypertension due to multifactorial unspecified causes. In the pathophysiology, pulmonary hypertension occurs when the balance is disturbed by endothelial dysfunction, decrease in vasodilator mediators (NO, prostacyclin) and increase in vasoconstrictor mediators (endothelin-1, serotonin, thromboxan) in the vascular bed. Perioperatively, patients with WHO functional classification >2, right ventricular hypertrophy, obese, chronic renal failure, previous PTE, COPD, diabetes mellitus are more prone to complications related to pulmonary hypertension. Although factors such as emergency surgery, intraoperative vasopressor use, delayed intubation, acidosis, and hyperthermia pave the way for postoperative pulmonary complications, attention should be paid to mortality and morbidity since they are also preventable factors. Postoperatively, as a result of the supine position triggering bronchospasm with secretions, acute lung injury in addition to the existing comorbidity occurs. With the increase in respiratory workload, acute respiratory failure develops with symptoms such as hypoxemia and hypercarbia. Residual anesthesia, increased pain or prolonged mechanical ventilation time also decrease functional residual capacity, increasing the possibility of atelectasis development. With the records we kept in our study, we aimed to show which complications the patients with pulmonary hypertension faced after their surgeries due to their underlying diseases and References ESC/ERC Guidelines Eurepean Heart Journal 2016; 37:67-119 Aguirre MA, et al.

The planned intervention, entitled, Supporting Self-Management of Health Behaviors to Optimize Health (SMART-HABITS for Health), aims to provide support for patients with chronic kidney disease, hypertension and diabetes by providing text messages delivered as motivational reminders and support to encourage blood pressure self-monitoring through goal setting, customized task prompts via text message and feedback, leveraging social connections, and use of a gamification design.
STEP-Pre is to investigate the benefits of using anti-hypertensive drugs in the population with a blood pressure of 130-139/80-89 mmHg and evaluate the health economics. STEP-Pre is a multi-center randomized clinical trial. The cohort will be randomized into the treatment group or control group with a 1:1 ratio. The treatment group will take anti-hypertensive medicine to control blood pressure under 130/80 mmHg. Both groups will take health care education. STEP-Pre will last 4 years.
The purpose of this research study is to find out more about the drug treprostinil via inhaler and the mechanisms of why patients with pulmonary arterial hypertension related to Interstitial Lung disease (PAH-ILD) have limitations during exercise. The investigator is studying treprostinil's effect on patients with PAH-ILD during exercise and its effect on their quality of life after using it for 3 months.
Renal denervation is a new method to lower blood pressure (BP) in hypertensive patients by reducing the impact of sympathetic nervous system. Its efficacy has been demonstrated in resistant hypertension and in lowering BP in essential hypertension as compared to a sham procedure in untreated hypertensive patients. This procedure is safe without any serious adverse events. However its effects during pregnancy are unknown. Normal pregnancy is associated with an increase of sympathetic activity at rest and upon cardiovascular reflexes stimulation which returns to baseline after delivery. These changes maintain optimal utero placental blood flow. But excessive stimulation of sympathetic activity may play a role in preeclampsia. Drugs that may affect the sympathetic nervous system are considered as safe in pregnant women. So there are reasonable evidence that renal denervation performed before pregnancy should not have deleterious effects for the fetus. The efficiency of renal denervation being greater in young patient and in women, a greater proportion of BP normalization can be expected in this population of young women .
The investigators aim to objectively identify the Traditional Chinese Medicine (TCM) syndrome differentiation of type II diabetic and prediabetic patients in Singapore through modern technologies thereby potentially increasing the accuracy of identification, diagnosis, and prevention of diabetes and prediabetes through a system of targeted treatment. This observational study integrates the concept of TCM diagnostic methods with modern tools aim to provide an objective view on the syndrome differentiation of diabetic and prediabetic patients in Singapore and hence provide a guideline in the treatment options targeted specifically at Singaporeans demographic. A total of 250 subjects with 50 allocated in each group will be recruited to ensure a sufficient sample size for statistical analysis of the diabetic and prediabetic syndrome differentiation. Subjects aged 21-65 years old, of either gender, with no limitations on race, and is diagnosed with either diabetes (FPG ≥ 7.0 mmol/L, or 2hPG ≥ 11.1mmol) or prediabetes (IFG of FPG 6.1-6.9 mmol/L, and/or IGT with 2hPG of 7.8-11.0 mmol/L) will be included. Subjective and objective assessments through health evaluation, Physical Activity Questionnaire and Sugar Intake, Constitution in Chinese Medicine Questionnaire, radial pulse diagnosis and tongue diagnosis will be performed for each subject in a single visit. Statistical analysis of assessments will be conducted using unpaired t-test with significance level of p<0.05. Statistical software SPSS 15.0 (SPSS Inc.) will be used for the analysis.
This study will examine the effects of 4 months of aerobic interval training versus continuous aerobic training on ambulatory blood pressure (ABP) and novel plasma protein biomarkers in patients with resistant hypertension. In addition, we will measure ABP after a training cessation period of 3 months (i.e., 7 months follow-up). A randomized controlled trial will be performed including two exercise groups and a control group: a) moderate-intensity interval training (MIIT); b) moderate-intensity continuous training (MICT); c) usual care. MIIT could represent a superior training modality that exceeds the benefits of MICT in patients with resistant hypertension.
