NCT ID: NCT00518479 Completed - Hypertension Clinical Trials

Pathophysiological Mechanisms of Hypertensive LVH:Optimising Regression

Start date: September 2003
Phase: N/A
Study type: Interventional

Uncontrolled high blood pressure can cause heart muscle 'thickening', and this increases the likelihood of complications and death. The high blood pressure explains some but not all of this increase in heart size. This study will investigate the other causes, and will measure the heart muscle 'thickness' very accurately using the latest and most accurate technique called cardiac magnetic resonance imaging (MRI). The best way to treat this heart thickening remains to be determined. We hope to be able to show that by specifically targeting the cause of heart muscle thickening we can reduce its occurrence more effectively than by other standard means of blood pressure treatment

NCT ID: NCT00497146 Completed - Clinical trials for Chronic Kidney Disease

The PRIMO Study: Paricalcitol Capsules Benefits Renal Failure Induced Cardiac Morbidity in Subjects With Chronic Kidney Disease Stage 3/4

PRIMO
Start date: February 2008
Phase: Phase 3
Study type: Interventional

To evaluate the effects of paricalcitol capsules on cardiac structure and function over 48 weeks in patients with Stage 3/4 chronic kidney disease (CKD) who had left ventricular hypertrophy (LVH).

NCT ID: NCT00446563 Completed - Clinical trials for Hypertension; Hypertrophy, Left Ventricular

Efficacy and Safety of Valsartan in Combination With Amlodipine Compared to Losartan Plus Hydrochlorothiazide in Patients With Hypertension and Left Ventricular Hypertrophy

Start date: March 2007
Phase: Phase 3
Study type: Interventional

This study will evaluate the safety and efficacy of amlodipine plus valsartan in patients with hypertension and left ventricular hypertrophy

NCT ID: NCT00368147 Completed - Clinical trials for Arteriovenous Fistula

Access Creation for Hemodialysis: Association With Structural Changes of the Heart

Start date: April 2002
Phase:
Study type: Observational

The purpose of this study is to determine if the creation of a fistula or a graft plays a role in the development of heart disease for patients undergoing hemodialysis

NCT ID: NCT00364260 Completed - Anemia Clinical Trials

A Safety and Efficacy Study for Epoetin Alfa in Pre-dialysis Subjects.

Start date: December 1997
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine if using Eprex, to maintain hemoglobin within the normal range, will prevent or delay the progression of left ventricular mass growth.

NCT ID: NCT00362037 Completed - Hypertension Clinical Trials

I SELECT - Irbesartan In Hypertensive Patients With Left Ventricular Hypertrophy

Start date: March 2006
Phase: Phase 4
Study type: Interventional

- To evaluate Blood Pressure (BP) reduction to the targeted values (BP ≤ 140/90 mm Hg in non-diabetic patients, and ≤ 130/80 mm Hg in diabetic patients). - To emphasize and to evaluate the benefit of Irbesartan in the reduction of left ventricular mass index in hypertensive patients with left ventricular hypertrophy. - To demonstrate safety of Irbesartan in this population.

NCT ID: NCT00348686 Completed - Hypertension Clinical Trials

Candesartan Effectiveness Study in Pro-B Type Natriuretic Peptides (BNP)

Start date: June 2006
Phase: Phase 4
Study type: Interventional

The purpose of this study is to investigate effect of candesartan based therapy on percent change of B type natriuretic peptides(BNP) level in the subjects with hypertension and left ventricular hypertrophy.

NCT ID: NCT00344903 Completed - Obesity Clinical Trials

Dallas Heart Study 2: Return Clinic Visit for the Dallas Heart Study Cohort

Start date: September 2007
Phase: N/A
Study type: Observational

The Dallas Heart Study (DHS-1) is a large, multi-ethnic, population-based epidemiological study designed to identify determinants of atherosclerotic heart disease (ASHD) in a representative United States (US) urban environment. This study completed enrollment in 2003. Our objective is to pinpoint factors contributing to progression: 1. from health to ASHD risk; 2. from ASHD risk to subclinical ASHD; and 3. from subclinical to clinical ASHD. Identification of the critical factors in these transitions will enable targeted implementation of appropriate therapy to interdict before clinical ASHD develops.

NCT ID: NCT00338260 Completed - Clinical trials for Hypertension and Left Ventricular Hypertrophy (Thickening of the Main Pumping Chamber of the Heart)

Losartan Intervention For Endpoint Reduction in Hypertension (LIFE) Study (0954-133)

Start date: June 1995
Phase: Phase 3
Study type: Interventional

The LIFE study was conducted from 1995-2001. This study was conducted in 9193 patients with high blood pressure and thickening of the main pumping chamber of the heart. The results showed that after an average treatment time of 4.8 years, treatment that was based on losartan was better than treatment based on atenolol for reducing the risk of having a stroke. The main study results were published in Dahlof et al. Lancet 2002;359:995-1003.

NCT ID: NCT00219141 Completed - Hypertension Clinical Trials

Aliskiren in Combination With Losartan Compared to Losartan on the Regression of Left Ventricular Hypertrophy in Overweight Patients With Essential Hypertension

ALLAY
Start date: October 2005
Phase: Phase 3
Study type: Interventional

To compare the efficacy and safety of aliskiren in combination with losartan compared to losartan on the regression of the increased size of the left ventricle in overweight patients with high blood pressure.
