Active clinical trials for "Hypertension"

The aim of the present study is to identify changes in the cardiovascular system in patients with pulmonary hypertension (PH) by magnetic resonance imaging (MRI). MRI is accepted as golden standard method for the evaluation of left and right ventricular morphology and function. All patients who showed elevated pulmonary pressure in the right heart catheter investigation are assigned to MRI. Parameters derived from MRI are included in the clinical and therapeutic decisions. Well established as well as new MRI parameters are evaluated and compared to the results of right heart catheter. Further age-matched controls without known cardiac or pulmonary disease are investigated by native MRI.

The purpose of this study is to observe treatment with candesartan cilexetil 16mg for 8 weeks, in uncontrolled hypertensive patients, in improvement of achieving of treatment goals and impact on blood pressure level in patients with uncontrolled hypertension treated with candesartan cilexetil.

This study will address the treatment rate and control rate of hypertension, treatment pattern and factors that affect BP control by examining retrospective medical records of hypertension patients recovering from stroke, among outpatients coming to the Neurology Department in 10 university hospitals nationwide.

To evaluate (with sufficient accuracy) the profile(demographic and clinical characteristics, health care management) of hypertensive patients seen in hospital out patient's department by a cardiologist or a nephrologists.

To evaluate (with sufficient accuracy) the profile(demographic and clinical characteristics, health care management) of hypertensive patients seen in general practitioner consultation.

The aim of this multi-centre survey is to assess treatment adherence and quality of life in a Jordanian and Lebanese population newly diagnosed with hypertension or with uncontrolled essential hypertension being on antihypertensive treatment for at least 6 months.

The investigators aim to investigate whether central systolic blood pressure, as measured during regular 24 hour ambulatory blood pressure monitoring (ABPM), is a better predictor of left ventricular mass than peripheral systolic blood pressure during ABPM.

The study will look at the risk factors for pulmonary hypertension (high blood pressure in the lungs) in children and adolescents with sickle cell anemia (SCA) and examine the role of hypoxia (oxygen shortage) in the disease. In patients with SCA, red blood cells become sickle-shaped and tend to form clumps that get stuck in blood vessels, blocking blood flow to the limbs and organs. Blocked blood vessels can cause pain, serious infections, and organ damage. Many patients with SCA also develop pulmonary hypertension. Children and adolescents with SCA or Chuvash polycythemia (another blood disorder that carries an increased risk for pulmonary hypertension) may be eligible for this study. Participants undergo the following procedures at the beginning (baseline) and end of the study: History, physical examination and blood tests . Echocardiography (ultrasound study of heart function). Transcranial doppler (brain ultrasound study to measure brain blood flow). Lung function tests. 6-minute walk (measure of the distance covered in 6 minutes of walking). In addition, patients are followed by telephone or by clinic visits every 6 months for a review of their medical history and medications. A physical examination is also done at 12 months.

Clinical validation of the Tiba Medical Ambulo 2400 ambulatory blood pressure monitoring system according to the accuracy guidelines of the ISO 80601-2-30 Standard in Adults, Adolescents, and Children.
