Research Study for Heart Disease Patients Undergoing Cardiac Catheterization

Study Summary

The University of Chicago and Dr. John Lopez are conducting a research study for patients who have heart disease and are scheduled to undergo a procedure to look at the blood vessels of their heart (cardiac catheterization). Also, this procedure will involve locating and treating blocked blood vessels. The purpose of this research study is to determine whether the blockages in the heart blood vessels are caused by how the blood flows in the blood vessels and whether we can predict the future status of the patient's disease from the status that can be observed now. This is done by combining x-ray and ultrasound (sound wave) images, with blood pressure measurements.

You will be in this study for approximately five years. You will have your cardiac catheterization procedure at the first visit as part of your normal routine medical care. You will have a second catheterization for follow-up heart imaging procedures done approximately one year later at the second visit. Lastly, you will receive follow-up phone calls about once a year from the study staff until five years after your first visit.

Subjects who participate in this study will be compensated $100 for travel related expenses after completing the second visit.

Benefits

You may not benefit directly from this research. However, the medical knowledge obtained from this study may be of considerable benefit to help treat patients with heart disease in the future.

Initial selection criteria include:

• Must be age 18 years or older
• Must have a history of heart disease requiring cardiac catheterization
• Females of child-bearing potential must have a negative blood pregnancy test in order to participate
• Must meet study medical criteria as evaluated by Dr. Lopez
