Conducted by Dr. David Kass and his team the study observed how Viagra affected the heart of 35 participants who had no past or present signs of heart disease.

For the study, the participants were injected twice with dobutamine (a drug that increases heart rate and the power with which the heart pumps blood) over a three hour period. The patients were randomly given a dose of Viagra or a placebo after the first injection. 

It was observed the heart rate increased by dobutamine dropped by nearly 50% for patients who were given Viagra. Researchers determined this action was on account of Viagra’s ability to block the enzyme PDE-5. The blocking of this enzyme actually helps reduce the effects of stress on the heart and thereby make it healthier.

Talking about their discovery, Dr. Kass, who is the Abraham and Virginia Weiss Professor of Cardiology at Johns Hopkins said, “What we have recently discovered is the enzyme Viagra and drugs like Viagra block acts kind of like a brake for the heart.” Describing the condition further, he said, “the brake does come into action in normal conditions, but if applied when there is stress, you can really blunt stress response in the heart.”

“It's an unusual new discovery initially coming out of left field,” Dr. Kass said. “If you push your foot on the accelerator pedal without Viagra, you’re suddenly going 100 miles per hour. With Viagra, you're only able to go 35 an hour. So, it’s blocking the adrenaline stress on the heart,” he added.

Previous tests conducted by the team in mice showed dramatic results with hearts enlarged by extreme stress regaining their normal size when Viagra was administered. The above study was the first round of tests on healthy human patients and researchers are highly optimistic about the positive results.

Viagra is already an approved drug, so if the results hold up, the possibility of the drug becoming standard treatment for the heart in a few years was a distinct possibility. If this use for Viagra is approved, it could have major implications for patients with heart disease.

Commenting about the sexual effects of Viagra, Dr. Kass noted, “Viagra taken for cardiovascular purposes does not cause sexual stimulation, because that side effect requires the right environment.”
