Active clinical trials for "Hypertension"

To assess the efficacy of telmisartan in hypertensive patients with high cardiovascular risk

Myelodysplastic and myeloproliferative Disease represent conditions with increased risk for pulmonary hypertension. However, the exact prevalence of pulmonary hypertension in these conditions is not known. The effects of pulmonary hypertension on the clinical picture and the symptoms of patients in these conditions needs also further exploration. This exploratory study is designed to describe the prevalence of pulmonary hypertension in the population with such hematologic diseases, and the stages of pulmonary hypertension as well its effect on exercise capacity at time of diagnosis.

The prevalence of an increased pulmonary blood pressure amongst patients with chronic obstructive pulmonary disease (COPD)is unclear. So is the impact of abnormal pulmonary blood pressure on symptoms. The aim of this study is to determine the prevalence of an increased pulmonary blood pressure in 200 patients with COPD. Furthermore we will investigate if lung function test results and blood tests can predict an increased pulmonary blood pressure, and explore whether COPD patients with a high pulmonary blood pressure have more symptoms that their co-patients.

The CandLE study with at maximum daily dose of 32 mg candesartan or 16/12.5 mg candesartan/hydrochlorothiazide has the objective to evaluate under naturalistic conditions, i.e. under routine medical care conditions, the impact of the antihypertensive therapy with candesartan or candesartan/HCT on relevant medical parameters related to the left ventricular hypertrophy (LVH) as well as the efficacy and tolerability of candesartan or candesartan/HCT in subjects suffering from essential hypertension..

The Ocular Hypertension Treatment Study is a multi-center clinical trial sponsored by the National Eye Institute, designed to determine the efficacy and safety of topically administered eye lowering medication

The aim of the study is to find simple clinical and laboratory parameters to predict the development of hypertension and to elucidate the mechanism of hypertension during treatment with the tyrosine kinase inhibitor Sunitinib.

The goals of this trial are to determine the prognostic significance of an elevated level of inflammatory blood markers in people who have experienced small subcortical strokes and who are enrolled in the Secondary Prevention of Small Subcortical Strokes (SPS3) trial.

1.11 Retrospectively evaluate for a correlation between tumor response and changes in systolic/diastolic/mean arterial blood pressures in patients treated with bevacizumab, with or without chemotherapy, with a wide variety of metastatic malignancies. 1.12 Retrospectively evaluate for differences in tumor response between patients with and without pre-existing hypertension treated with bevacizumab plus or minus chemotherapy with a wide variety of metastatic malignancies. 1.21 Determine if there were differences in bevacizumab induced hypertension rates between different tumor types. 1.22 Evaluate for differences in bevacizumab induced hypertension rates between males and females. 1.23 Examine if there were associations between a particular chemotherapeutic agent(s), that may have had an increased propensity of inducing hypertension when combined with bevacizumab.

High blood pressure is a global public health problem in developed and developing countries including Pakistan. Various studies conducted around the world have linked salt intake to variation in the blood pressure.However, definite conclusions are lacking and the exact role of dietary salt in salt-blood pressure relationship remains controversial. While clinical practice guidelines recommend dietary salt restriction for lowering blood pressure, the relationship of salt with blood pressure has not been tested in the Pakistani population. Therefore, the efficacy of dietary salt restriction on blood pressure of this population remains to be determined. The study aims to determine the relationship between dietary salt intake and blood pressure in Pakistani population. It is hypothesized that alteration in the dietary salt intake demonstrates significant changes in the Systolic BP.

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: from health to ASHD risk; from ASHD risk to subclinical ASHD; and 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.
