Active clinical trials for "Hypertension"

This study will evaluate the use of N-acetyl cysteine in post-reperfusion pulmonary injury in patients with chronic thromboembolic pulmonary hypertension undergoing pulmonary balloon angioplasty and pulmonary endarterectomy. Half of the patients will receive N-acetyl cysteine and the other placebo.

The purpose of this study is to test the impact of a personalized, partly supervised rehabilitation program on the exercise capacity in patients with pulmonary hypertension. The rehabilitation program consists of 2 weeks inpatient, 2 weeks ambulatory and 11 weeks home based rehabilitation.

The goal of this study was to assess the efficacy and safety of FDC therapy with triple therapy of Telmisartan 40 mg/Amlodipine 5 mg/Rosuvastatin 10mg in Korean patients with both hypertension and dyslipidemia.

Pulmonary arterial hypertension (PAH) is a disease characterised with significant morbidity and poor prognosis. Dyspnoea and impaired exercise capacity are very common manifestations of the disease, and result in significant impairment of patients' quality of life. Although hypoxemia is common among subjects with PAH, published data on the effects of supplementary oxygen therapy on specific clinical outcomes among these patients are currently few, while the existing data on the potential benefits of oxygen supplementation to treat exercise-induced hypoxemia, in this patient population, are even more controversial. Based on the aforementioned, the purpose of this prospective, crossover clinical trial is to investigate the acute effects of supplemental oxygen administration on the: a) exercise capacity, b) severity of dyspnea, c) cerebral oxygenation, b) muscle oxygenation, and e) hemodynamic profile, as compared to delivery of medical air (sham oxygen), in a group of patients with PAH, during steady state cardiopulmonary exercise testing (CPET)

Having the advantages of being minimally invasive and simple, extracorporeal shock wave lithotripsy (SWL) remains one of the treatment options for renal stones less than 2cm. Although SWL is the most minimally invasive surgical approach for stone, there are still some concern about its short and long term side effect. While, there are some evidences that SWL might lead to increase in new onset hypertension, investigator's recent study suggested it might also cause worsening of blood pressure control in patient with known hypertension. Therefore, further studies are needed to confirm the initial finding. This study recruits patients who have hypertension and are currently diagnosed to have renal stone and planned for SWL, in order to to investigate the effect of SWL on blood pressure control. After informed consent and background information have been obtained, patients will be randomized to either have routine SWL (treatment arm) or 6 months later (control arm). Group 1 patients will have blood pressure monitored for one day at home by an handy automated blood pressure measuring machine before SWL and 6 months after SWL. Group 2 patients will have blood pressure monitoring immediately and then 6 months later, just prior to the SWL.

Despite advances in treatment and corresponding improvements in survival, patients with pulmonary arterial hypertension (PAH) remain highly symptomatic. In one survey of 315 patients with PAH, sixty-eight percent had moderate or severe dyspnea on exertion and 40% had a profound and clinically significant deficit in quality of life. Palliative care is being increasingly investigated in life-limiting cardiovascular diseases to alleviate symptoms. In PAH, its implementation is frequently delayed until end-of-life. Opioids are a common palliative care intervention, however the efficacy and safety of opioids for symptom relief in PAH has not been evaluated.

The carotid body is located at the bifurcation of the internal and external carotid arteries. It is a chemoreceptor that plays a role in the sympathetic nervous system and in the development and maintenance of hypertension. Hypertension is a major cardiovascular risk factor and is associated with coronary artery disease, stroke, chronic kidney disease, and heart failure. The objective of this study is to assess the effectiveness and safety of a catheter-based system to ablate the carotid body and reduce blood pressure (BP) in patients with resistant hypertension and to confirm sustainability of the treatment benefits long-term as seen following surgical CB removal.

Cardiovascular morbidity and mortality is increased in kidney transplant patients. High blood pressure (BP) contributes significantly to this risk and is also associated with shortened allograft survival. Salt reduction lowers BP in the general population and there is emerging data that salt reduction also effectively lowers BP in chronic kidney disease (CKD). Kidney transplant patients, by definition have CKD, but they differ fundamentally from the general CKD population in that they are on medications which can predispose to high blood pressure, their kidneys are denervated, and they often have reasonable excretory kidney function. The proposed study will be an eight-week randomised, controlled trial assessing the effect of intensive dietary salt advice on cardiovascular risk factors in kidney transplant patients. The primary outcome is office BP readings, with the effect on 24-hour ambulatory blood pressure, proteinuria, arterial stiffness and endothelial function being studied as secondary outcomes.

A total of 240 hypertensive subjects aged 40-69 years (including 126 patients complicated with diabetes) will be included in a few communities in Beijing, and will be divided into 3 groups according to the individual wishes of the subjects: walking group(n=80, including 42 patients complicated with diabetes), Chinese square dancing group(n=80, including 42 patients complicated with diabetes) and control group(n=80, including 42 patients complicated with diabetes). All exercise sessions will be supervised and subject's exercise implementation process will be managed with intelligent equipment. The purpose of the study is to evaluate the effectiveness and safety of different training programs in the real world. The demographics data, physical activity questionnaires, blood pressure, blood glucose, blood lipids, height, weight and physical fitness （cardiorespiratory fitness,muscle strength, muscle endurance, flexibility, body composition)will be measured before and after 3-month exercise training .The adverse reactions in the implementation of the interventions will be recorded. The primary outcomes are blood pressure and blood glucose.

Hypertensive disorders of pregnancy are important cause of severe morbidity, long-term disability and death among both mothers and their babies. In Africa and Asia, nearly one tenth of all maternal deaths are associated with hypertensive disorders of pregnancy research has focused on the antenatal complications' for both mother and baby and the risks and benefits of administering antihypertensive therapy prior to delivery hypertension disorders of pregnancy often persist following delivery and sometimes arise de novo postpartum one of the maternal complications of pre eclampsia is residual chronic hypertension in about 1/3 of cases elevated blood pressure is seen in 6%to 8% of all pregnancies hypertension (arterial pressure >140/90 mmhg) in pregnancy is classified into one of four conditions chronic hypertension that precedes pregnancy pre eclampsia and eclampsia: a systematic syndrome of elevated arterial pressure,proteinuria and other findings pre eclampsia superimposed upon chronic hypertension gestational hypertension or nonproteinuric hypertension of pregnancy
