Transcutaneous Electrical Nerve Stimulation (TENS) on Arterial Stiffness and Blood Pressure

HypertensionVascular Stiffness1 more

Uncontrolled blood pressure represents the main factor in the development of target organ lesions and, consequently, cardiovascular events, which are the leading cause of morbidity and mortality worldwide. In most cases resistant hypertension is preceded by target organ lesions, and is strongly influenced by risk factors or associated diseases. To control this disease requires an adequate and intense therapeutic approach that includes lifestyle changes and the use of several antihypertensive drugs. However, the results are not always satisfactory despite intensive treatment. Of the different pathophysiological mechanisms involved in the pathogenesis of resistant hypertension (RH), two, sympathetic overstimulation and therapies that block the sympathetic system, have been widely studied. But, these approaches are invasive and expensive. Another possible approach is by transcutaneous electrical nerve stimulation (TENS), a non-invasive method that modulates activity by inhibiting primary afferent pathways using low-frequency transcutaneous electrical stimulation. Some studies have shown that TENS reduces blood pressure in patients with hypertension. The current study will evaluate the effect of applying TENS in the cervicothoracic region of subjects with resistant hypertension, seeking to develop a new low cost and readily available therapy to treat this group of hypertensive individuals.

Prevention of Severe Postpartum Hypertension

Hypertension

The purpose of this study is to determine whether postpartum administration of furosemide to women with antepartum hypertensive disorders (gestational hypertension, preeclampsia) or elevated blood pressure in the first 24 hours following delivery reduces severe postpartum hypertension.

Mobile Phone-based Intervention for Promoting Healthy Habits and Weight Loss

DiabetesHypertension5 more

A self administered 16 weeks plus follow up study to explore the efficacy of mobile phone driven apps for stress reduction coupled with guidance for healthy living among obese and overweight populations. The Study primary end points are weight of the participants, as well as glucose measurements (for subject with diabetes) and blood pressure (of subjects with hypertension).

Postoperative Pain and Angiotensin II Receptor Antagonists

Hypertension

An angiotensin II type 2 receptor (AT2R) antagonist has been assessed for its efficacy in neuropathic pain with promising results. A considerable number of patients undergoing surgery under general anesthesia are hypertensive and receive drugs to control high blood pressure, including angiotensin II receptor antagonists. These drugs may attenuate the acute and/or chronic postoperative pain or decrease the analgesic requirements after surgery. The aim of the present study is to assess the early postoperative pain and analgesic requirements in patients treated with antagonists of the angiotensin II receptors for at least three months before surgery compared to normotensive patients.

Pharmacodynamic Equivalence of Ramipril 10 mg and Atorvastatin 40 mg Administered as a Cardiovascular...

Hypertension

This study is to compare the pharmacodynamics of a Fixed Dose Combination Pill AAR (acetylsalicylic acid 100 mg, atorvastatin 40 mg and ramipril 10 mg) and the respective reference products, atorvastatin (Lipitor®) 40 mg and ramipril (Altace®) 10 mg.

A Comparison of Xalatan (Latanoprost) to Apo-latanoprost and Co-latanoprost in the Treatment of...

POAGPrimary Open Angle Glaucoma1 more

The purpose of the study is to provide evidence that the efficacy of Xalatan will be superior to Apo-latanoprost and Co-latanoprost in the reduction of intraocular pressure in patients with primary open angle glaucoma. The study will also aim to prove the tolerability of Xalatan in terms of ocular hyperemia will be equivalent to its generic counterparts.

Pilot Study of Aprepitant Effect on Aldosterone Secretion in Diabetic Patient (Diabetes Mellitus)...

Type 2 DiabetesHypertension

Aldosterone regulation is mediated by hormonal control, and nervous control. Autonomic nervous system action could be mediated by neuropeptides in the adrenal gland. Therefore, in pathological conditions and especially in diabetes, low-renin hypertension with normal or high plasma aldosterone could be caused by sympathetic nervous system hypertonia. Data from the literature and previous in vitro research conducted in the investigators' laboratory (INSERM U982, University of Rouen) suggest that adrenal corticosteroid secretion might be controlled by sympathetic nervous system. This neurocrine regulation of corticosteroid secretion involves locally released neuropeptides. Among them, substance P is able to stimulate aldosterone and cortisol production via NK1 receptors. A previous clinical trial conducted at the University Hospital of Rouen, APHOS (NCT00977223) studied the effects of a NK1 receptor antagonist, aprepitant, on adrenocortical secretions in healthy volunteers. The aim of the present study is to investigate the effects of a NK1 receptor antagonist, aprepitant, on adrenocortical secretions in volunteers with diabetes associated with low-renin hypertension. Aprepitant is a drug already available for the treatment of nausea induced by chemotherapy. In the present phase II trial, plasma aldosterone and cortisol levels will be measured under treatment with aprepitant versus placebo, in both basal conditions and after activation of the adrenocortical function by upright posture. All volunteers will be given the two substances (aprepitant and placebo) in a random order during two 14 day-periods separated by a 21 day-wash-out. This study should allow to determine the role of substance P in the control of corticosteroid production in human with diabetes, associated with a low-renin hypertension.

Feasibility Study of the Intensive Systolic Blood Pressure Control

HypertensionHyperhomocysteinemia

The purpose of the current feasibility study is to test whether the blood pressure level of the study patients can be effectively and safely managed according to the intensive antihypertensive treatment protocol. Furthermore, the study will also examine the effect of intensive antihypertensive treatment on the intermediate cardiovascular diseases outcomes, including CIMT, carotid plaques, PWV ABI, and kidney function, etc.
