Hypercholesterolemia, Hypertension
Effects of Rosiglitazone on Blood Vessels in Patients With High Blood Pressure and High Cholesterol
Cells in the lining of blood vessels produce various substances that cause the vessels to dilate (relax) and constrict (tighten), thereby regulating blood flow.

Cardiomyopathy, Hypertrophic, Coronary Disease
Analysis of Heart Muscle Function in Patients With Heart Disease and Normal Volunteers
Myocardial ischemia is a heart condition in which not enough blood supply and oxygen reaches the heart muscle. Damage to the major blood vessels of the heart (coronary artery disease), minor blood vessels of the heart…

Study of the Effects of Temperature on Metabolism in Human Muscle
This study will examine the role of temperature in changing energy metabolism in human muscle. In order to do this, researchers will use magnetic resonance imaging (MRI) to provide information about how parts of muscle operate…
- Trial name
- NCT00001753
- Testing
- Magnetic resonance imaging

Coronary Disease, Healthy
Study of Blood Flow in Heart Muscle
Blood flows to areas of the heart providing oxygen and fuel to the pumping muscle. Occasionally the arteries providing the fuel can become blocked. This occurs in coronary artery disease.
- Conditions
- Coronary Disease, Healthy, Hypertrophic Cardiomyopathy, Myocardial Ischemia
- Trial name
- NCT00001631
- Testing
- Magnetic resonance imaging
- Where
- United States
- Volunteers
- 249 people, healthy volunteers welcome

Asthma, Healthy
Factors Involved in Asthma and Airway Inflammation
Asthma is the third leading cause of preventable admissions to the hospital in the United States. Deaths and diseases associated with asthma increase every year. Asthma is a disorder of airway inflammation.

Determination of Variances in Exhaled Nitric Oxide Output in Normal Healthy Male Volunteers Consuming High and Low Nitrate/Nitrite Diets
This study will determine whether and how nitrites and nitrates in the diet affect the level of nitric oxide gas that is breathed out in air.

Arterial Occlusive Diseases, Atherosclerosis
Potential Role of CMV in Restenosis Following Angioplasty, in Atherosclerosis, and in Endothelial Dysfunction
The purpose of this study is to investigate whether the susceptibility of subjects to atherosclerosis is influenced by prior CMV exposure, whether the susceptability to endothelial dysfunction in patients with and in patients…

Effects of Miconazole on Blood Flow
This study will investigate the effect of the drug miconazole on blood vessel dilation. Miconazole stops production of EDHF, a substance that causes arteries to dilate. EDHF is produced by the cells that line blood vessels.

- NCT00004575
- Testing
- Miconazole, L-NMMA, Bradykinin
- Where
- United States
- Volunteers
- 15 people, healthy volunteers welcome

Atherosclerosis, Heart Failure, Congestive
The Role of Angiotensin Type I Receptor in the Regulation of Human Peripheral Vascular Function
The renin angiotensin system (RAS) plays an important physiological and pathophysiological role in the control of blood pressure and plasma volume.
