Researchers want to understand why men with heart disease often experience erectile dysfunction. This study uses two specialized imaging techniques—intravascular ultrasound (IVUS) and near-infrared spectroscopy (NIRS)—to look closely at the arteries that supply blood to the penis in men who are already undergoing heart catheterization. By comparing the health of these arteries to sexual function scores, the researchers hope to understand the connection between artery disease in the heart and sexual problems.
Erectile dysfunction is very common in men with coronary artery disease, but doctors don't fully understand why. This study exists to determine whether the same buildup of plaque that damages heart arteries also damages the smaller arteries involved in sexual function, which could explain this link and help guide future treatment.

If you qualify, you would already be undergoing a clinically necessary heart catheterization. After that procedure is complete, researchers would perform additional imaging of the arteries in your pelvis using two specialized ultrasound techniques—this takes extra time during your existing procedure. Within 30 days after your procedure, you would complete a simple 5-question survey about your sexual function. You would then have follow-up care scheduled with both cardiology and urology to monitor your health.
