Active clinical trials for "Hypertension"

Multi-centre survey of type 2 diabetic patients who are currently on anti-hypertensive treatment. Data collection for each patient will take place at one visit. To observe the proportion of diabetic patients on antihypertensive treatment reaching the BP<130/80 mmHg. To observe the proportion of diabetic patients on antihypertensive treatment reaching the BP<130/80 mmHg by treatment groups. To observe the proportion of patients achieving a therapeutic glycemic response defined as HbA1c=<7%. To observe the proportion of patients achieving fasting plasma glucose<110 mg%. To identify factors for not achieving BP<130/80 mmHg. To describe percentage of patients with positive proteinuria (including microalbuminuria) by treatment groups .

Twelve health organizations from around the US were selected to participate in a chart review Hypertension and Diabetes Initiative with the goal of improving blood pressure control in persons with diabetes. Hypothesis: A three-phase quality improvement initiative facilitated and monitored through the International Diabetes Center (IDC) will result in improved population-mean systolic blood pressure in the aggregate data pool of patients from all 12 participating sites at geographically distinct health systems.

International studies have repeatedly documented a substantial prevalence of sexual risk behaviors and high rates of human immunodeficiency virus (HIV) and other sexually transmitted infections (STI) ranging from 5%-56% amongst long-distance truck drivers ("truckers") living in diverse international settings including India, Bangladesh, South Africa, China, Laos and Thailand. The prevalence of sexual risk factors and STI/HIV in US drivers is unknown. This proposal will provide both qualitative and quantitative data on HIV risk behaviors by interviewing and testing truckers working for established long-distance trucking firms, the sector which accounts for most of the jobs in the trucking and warehousing industry in the United States. The data obtained from this study will be used to inform the development of an HIV prevention intervention for long-haul truck drivers.

The REVEAL Registry™ is a multicenter, observational, U.S.-based study of the clinical course and disease management of pulmonary arterial hypertension (PAH) patients. All consecutive consenting patients diagnosed with WHO Group I PAH according to specific hemodynamic criteria at participating institutions will be enrolled. Participating patients will be followed for a minimum of five years from the time of enrollment.

Psychosocial and lifestyle stressors, such as job strain (JS) and marital factors have previously been associated with a sustained increase in blood pressure (BP). In a one-year longitudinal follow-up to the Baseline Double Exposure cohort study, we, the researchers at Sunnybrook and Women's College Health Sciences Centre, evaluated whether JS and marital cohesion continued to be associated with ambulatory blood pressure (ABP) in subjects enrolled with normal or untreated high BP.

Acute cardiogenic pulmonary edema (ACPE), one of the most severe forms of acute heart failure, represents 5% of hospital admissions. One of the most frequent phenomena encountered during ACPE is hypertensive crisis (hypertensive ACPE) but the mechanisms and causes of hypertensive ACPE are insufficiently understood. Few studies have evaluated the cardiac function during hypertensive ACPE, and these studies used only conventional echocardiography methods. New methods of evaluation of cardiac function in hypertensive ACPE (such as Tissue Doppler imaging) have not been used. The objectives of this study are to evaluate presence and role of the following potential mechanisms of hypertensive ACPE: 1. acute myocardial dysfunction (systolic and diastolic); 2. silent transient myocardial ischemia; 3. acute mechanical left ventricular dyssynchrony; 4. dynamic mitral regurgitation; 5. inter-ventricular interaction. Conventional and Tissue Doppler echocardiography will be used to assess cardiac function.

The presence of an abnormally increased pulmonary blood pressure worsens the prognosis of patients with interstitial pulmonary disease. The aim of this study is to estimate the frequency of an increased blood pressure in the lungs among patient with interstitial pulmonary disease, and to evaluate the use of different biomarkers in diagnosis of the condition.

To support physicians in their active management of hypertensive patients. By targeting specific systolic and diastolic blood pressure (BP) figures physicians will closely monitor the BP values and as such will have an individualized control of the treatment in each patient.

The purpose of this study is to determine whether irbesartan will reduce the rate of recurrent atrial high rate episodes and the development of clinical sustained atrial fibrillation in patients with hypertension and permanent pacemaker.

To explore the meaning, causes and treatment of hypertension in eligible patients. In addition the cultural, social, and psychological factors that either facilitate or serve, as barriers to behavioral change will be illuminated in this patient population.
