Filter by:The HYGIA study was designed to investigate prospectively 1. the prognostic value of ambulatory blood pressure (BP) monitoring among subjects primarily evaluated at primary care settings 2. the impact of changes in ambulatory BP during follow-up in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 3. the influence of circadian time of treatment in cardiovascular, cerebrovascular, metabolic, and renal risk in hypertensive patients 4. the prevalence of an altered BP profile as a function of antihypertensive treatment, circadian time of treatment, age, and presence of diabetes, among other factors.
Hypertensive patients with moderate hypertension have a risk to develop cardiovascular events of 15-20% over a period of 10 years. It is important to reach quickly the advised target, but often this result can be obtained with a combination therapy. Some evidences demonstrate sartans and calcium channels blockers can be very useful and safe, but it is also important to verify which association can give side effects or give some pharmacokinetic interactions that can negatively influence the clinical combination efficacy.
This study will evaluate the efficacy and safety of weak extremely low frequency electromagnetic fields (ELF-EMF) in mild and moderate essential hypertension.
This study tested the safety of the combination of aliskiren/amlodipine/hydrochlorothiazide in participants with essential hypertension.
The anthypertensive treatment with Losartan may have benefits beyond blood pressure reduction on myocardial structure and function in hypertensive diabetic patients. We will evaluate the effect of losartan treatment on structural characteristics of myocardium in hypertensive diabetic patients: 1. left ventricular mass, intraventricular septal thickness, fractional shortening. 2. myocardial qualitative alteration and heterogeneity of myocardial tissue that describes myocardial texture and echodensity, related to collagen deposition; myocardial qualitative alteration will be evaluate by ultrasonic myocardial integrated backscatter signals (IBS) both as peak end diastolic signal intensity and as cardiac cyclic variation 3. alteration of diastolic function as studied by Doppler flow velocities across the mitral valve (Pulse Wave Doppler) and pulse wave Tissue Doppler Imaging parameters 4. aortic strain and distensibility (that is in relation with LVH) 5. epicardial adipose tissue measurement (this parameter is related to the visceral fat and may be an easy method to indicate patients with high cardiovascular risk).
This study will compare the safety and efficacy of once daily dosing of aliskiren to twice daily dosing of aliskiren in patients with moderate hypertension
BACKGROUND The effects of ACE-inhibitors on fibrinolysis are well documented. Experimental and clinical studies have shown that ACE inhibitors induce a reduction in plasma PAI-1 levels in many cardiovascular diseases, like hypertension, coronary heart disease, and heart failure. Their effects on t-PA are more controversial, due to the fact that t-PA exists in several forms, including free and bound to PAI-1. Indeed an increase in t-PA activity has been observed in humans and it seems related to bradykinin increase which is known to stimulate endothelial t-PA synthesis. These favourable effects on fibrinolysis could be related not only to the Angiotensin II reduction and the bradykinin increase but also to the improvement in insulin sensitivity, as insulin has been suggested as one of the main regulators of fibrinolytic activity. To date conflicting results have been reported about the effects of ARBs on fibrinolysis. Some studies have reported small improvements, others no significant effect. These conflicting results may be due to possible methodological bias but a possible pathophysiological explanation might be that receptor subtypes other than AT1 mediate the effect of Angiotensin-II on endothelial PAI-1 expression, i.e. the AT4 receptors, and during AT1 receptor blockade there is an important increase not only of Angiotensin-II, but also of all its catabolites including Angiotensin IV. The dissimilar effects on of ACE Is and ARBs may also depend on their different action on the RAS and their different effect on insulin sensitivity: ACE-Is improve insulin sensitivity, while the majority of ARBs have been reported to have a neutral effect. Moreover, unlike ACE-Is, ARBs do not affect the metabolism of bradykinin, which is known to stimulate t-PA synthesis and release. AIM OF THE STUDY The aim of this study is to verify the effect of imidapril compared to candesartan on insulin sensitivity, evaluated through the euglycemic hyperinsulinemic clamp, and on fibrinolysis, evaluated through the plasma PAI-1 and t-PA activity, in mild to moderate hypertensive patients.
The CoCa study with at maximum daily dose of 32 mg candesartan or 16/12.5 mg candesartan/hydrochlorothiazide has the objective to evaluate under naturalistic conditions, i.e. under routine medical care conditions, the subject compliance as well as the efficacy and tolerability of candesartan or candesartan/HCT in subjects suffering from essential hypertension.
The CandLE study with at maximum daily dose of 32 mg candesartan or 16/12.5 mg candesartan/hydrochlorothiazide has the objective to evaluate under naturalistic conditions, i.e. under routine medical care conditions, the impact of the antihypertensive therapy with candesartan or candesartan/HCT on relevant medical parameters related to the left ventricular hypertrophy (LVH) as well as the efficacy and tolerability of candesartan or candesartan/HCT in subjects suffering from essential hypertension..
The purpose of this study is to determine the optimal dosage of the clinical trial which is evaluating the antihypertensive efficacy and the safety of OJP-2028 tablets in patients with the uncomplicated essential hypertension.
