Clinical Trial Summary

This study will evaluate volunteers 18 years of age and older to see if they qualify for one of NHLBI s research studies. Tests include the following: - General medical evaluation, which may include blood tests, chest x-ray, electrocardiogram (ECG) and echocardiogram (heart ultrasound). - Other tests as appropriate, such as magnetic resonance imaging (MRI), cardiac computed tomography (CT scan of the heart), nuclear stress test and echocardiography stress test. - X-ray contrast studies of the heart and blood vessels. (These may be excluded in patients with kidney risk factors.)

Description:

This is a screening protocol. This protocol allows two functions: 1) the protocol allows physicians in the Suburban/NHLBI Cardiovascular Imaging program to evaluate patients referred to the program with clinically indicated studies and research studies. 2) It is also designed to determine if patients may be suitable candidates for one of our NHLBI research protocols. Patients greater than or equal to 18 years of age referred for possible cardiovascular disease will be enrolled in the protocol for a period of one year. At one year, patients will either be: 1) transferred to one of our specific research MRI or CT protocols, 2) removed from the screening protocol and made inactive, or 3) re-enrolled on the screening protocol with the patient s consent.

• Decompensated heart failure.

C. MRI Exclusion Criteria (excludes MRI scan only):

• Cardiac pacemaker or implantable defibrillator.
• Cerebral aneurysm clip.
• Neural stimulator (e.g. TENS-Unit).
• Any type of ear implant.
• Metal in eye (e.g. from machining).

• Severe kidney disease (less than 30 mL/min/1.73 m(2).

E. Vasodilator Exclusions (excludes some vasodilator stress testing):

• Asthma or chronic obstructive pulmonary disease (emphysema) actively treated with bronchodilators or leukotriene receptor antagonists (albuterol, seravent, atrovent, montelukast singulair, zafirlukast Accolate. These conditions only exclude adenosine and dipyridamole.
• Second degree (Type II) and third degree atrioventricular heart block.

F. Exclusions from Dobutamine stress MRI only:

• Severe problems with heart rhythms.

Intervention

Device:
• Toshiba Aquilion ONE CT
The Toshiba Aquilion ONE CT system has the ability to acquire whole organ volume images in a single rotation by utilizing an x-ray detector that is configured as 320 detector rows with a 0.5 mm width, providing a z-axis coverage of 16 cm of anatomy.
• SWiemens MRI scanner
Investigational or research MRI coils may be used in the protocol. The coils are noninvasive devices external to the body. The coils act as antennae to receive small radiofrequency signals out of the body. Coils of the type we use are used daily in clinical MRI practice.
