Active clinical trials for "Hypertension"

The purpose of this study is investigating the proportion of Cardiovascular disease risk factors of hypertensive patients.

The primary objective is to determine the prevalence of sleep disordered breathing in children with primary hypertension or pre hypertension. The secondary objectives are to determine any association factors for children with primary hypertension or prehypertension to have sleep disordered breathing be it gender, age, body mass index (BMI), family history (hx) or ethnic group.

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.

The main objective of this study is to describe the management of patients with cardiovascular risk factors in primary prevention among different European countries. The patient's participation consists of a single study visit during a routine visit of the patient to the clinic/office. Study variables will be measured: By an interview between physician and patient during the visit and/or available medical records' information: social and demographic patient characteristics, relevant family medical history, current medication. By questions asked to the physician: physician perception of patients' CV risk factor, guidelines adherence and cost-containment. By measurement performed to the patient during the visit: weight, height, BMI, waist and hip circumference will be measured. CV risk factors (blood parameters) will be measured by collecting available data documented within the last year in the medical records and by the collection and analyses of a blood sample during the visit.

The purpose of this study is to determine the efficiency of Olmesartan medoxomile (OLMETEC®) alone or in combination with hydrochlorothiazide (OLMETEC PLUS®) in the reduction of arterial blood pressure in patients with light to moderate hypertension, and to evaluate the percentage of patients that reach treatment goals using this antihypertensive regimen.

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 .

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.

The purpose of this study is to evaluate adherence to DuoTrav® when reinforced by the use of the Travalert™ Dosing Aid.

High blood pressure is one of the most common health problems in the United States. Genetic variations may cause some people to be more susceptible to developing high blood pressure. This study will identify variations in genes known to play a part in the development of high blood pressure.
