Study start date: August 1, 1997

Actual date on which the first participant was enrolled.

In this pilot study, magnetic resonance imaging (MRI) of myocardial enhancement during first passage of intravenously injected gadolinium contrast will be used to evaluate regional myocardial perfusion in patients with known or suspected coronary artery disease and hypertrophic cardiomyopathy. The MRI results will be compared with conventional radionuclide perfusion studies (ex. dipyridamole thallium). A clinically defined normal group will also be studied without radionuclide correlation.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

249 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
