View clinical trials related to Uncontrolled Hypertension.
Filter by:Hypertension is an underdiagnosed and undertreated disease in real-life. Blood pressure and kidney functions are known to be closely related. Increased serum level of Cystatin C, a sensitive biomarker for renal function, seems to predict adverse cardiovascular events. The investigators aimed to evaluate the predictive value of serum Cystatin C for control of hypertension in a community-based study.
The purpose of this observational study is to further evaluate the safety and performance of the EnligHTN™ Renal Denervation System in the treatment of participants with uncontrolled hypertension in clinical routine practice.

This is a prospective, single-arm, non-randomized and open label feasibility study. The study is intended to evaluate safety and efficacy of multi-electrode radiofrequency renal denervation in patients with uncontrolled hypertension.
The objective of this study is to demonstrate that the MDT-2211 renal denervation system is a safe and effective treatment for uncontrolled hypertension subjects despite treatment with 3 or more anti-hypertensive medications of different classes, of which one must be a diuretic, as best available antihypertensive therapy
The objective of the H-FIB trial is to determine the role of renal sympathetic denervation in the prevention of Atrial Fibrillation (AF) recurrence in patients with hypertension for whom a catheter-based AF ablation procedure is planned. Patients will be randomized to either AF catheter ablation (usual therapy) or AF catheter ablation plus renal sympathetic denervation.
Despite the development of numerous drug therapies designed to treat hypertension, it remains a considerable and poorly managed health, social and economic burden. For various reasons, including the significant health care costs of treatment, there are estimates that up to 65% of hypertensive patients have untreated and/or uncontrolled blood pressure (BP). Aside from its impact on renal function, chronic hypertension significantly increases the risk for stroke, coronary artery disease, heart failure, and vascular disease. It is believed to be involved in the progression of cardiac arrhythmias. This link between hypertension and cardiovascular health has been well described; as has their combined effect on the aging and obesity-battling Western world. The recently published results of the Symplicity HTN-2 trial (Renal sympathetic denervation in patients with treatment resistant hypertension) establishing the therapeutic benefit of catheter-based renal sympathetic denervation for hypertension, have enormous potential for the management of a large and challenging patient population. The proposed, multicenter trial will attempt to confirm and expand on this promising data by conducting a double-blinded, placebo-controlled trial. Patients may qualify to participate in this research study if their doctor has determined that they have drug-resistant, chronic hypertension. Overall participation in this research study should be about 13 months which includes about 1 month to start the study procedure and 12 months of follow-up after the study procedure.
The Symplicity HTN-3 study is a, multi-center, prospective, single-blind, randomized, controlled study of the safety and effectiveness of renal denervation in subjects with uncontrolled hypertension. Bilateral renal denervation will be performed using the Symplicity Catheter - a percutaneous system that delivers radiofrequency (RF)energy through the luminal surface of the renal artery.
