Magnetic Resonance Imaging in the Diagnosis of Pulmonary Hypertension

Pulmonary HypertensionVentricular Function2 more

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.

Central Blood Pressure Over 24 Hours (ABPM) and Left Ventricular Mass

Suspected Arterial Hypertension

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.

Pulmonary Hypertension, Hypoxia and Sickle Cell Disease

Chuvash PolycythemiaCerebrovascular Disease2 more

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.
