John Hopkins researchers say that Viagra reduces the stimulatory effects
of hormonal stress on the heart by half. Previous studies have shown
that the erectile dysfunction drug is effective in treating
hypertension. It works by expanding the blood vessels.
In the heart, Viagra (sildenafil citrate) blunts the strengthened
heartbeat caused by chemically induced stress, thereby lessening the
excess amount of blood and force used to pump it to the body. David
Kass, M.D. says “Sildenafil effectively puts a ‘brake’ on chemical
stimulation of the heart.” Kass is a professor at The Johns Hopkins
University School of Medicine and its Heart Institute, and is the study
senior author and cardiologist.
According to John Hopkins researchers, these findings are likely the
first to confirm that Viagra has a direct effect on the heart.
Researcher knew that the drug could be effective for treating
hypertension, but believed it had little direct effect on the heart.
Earlier research showed that Viagra had similar effects in mice,
blocking the short-term effects of hormonal stress in the heart.
Related studies by the John Hopkins team showed that sildenafil prevents
and reverses the long-term effects in the heart from chronic high blood
pressure.
Kass believes that this study confirms that sildenafil helps control
heart function only when the heart is under duress, but has little
impact under normal conditions. Even more amazing is that “sildenafil
could reverse the negative effects on heart muscle weakened by heart
failure and enlargement, a condition called hypertrophy.”
“Knowing more about the effects of sildenafil on heart function will
allow for safer evaluation of its use as a treatment for heart
problems,” says Kass. “Until now, it was widely thought that drugs like
sildenafil had no effects on the human heart and that its only purpose
was vasodilation in the penis and the lungs.
“Our results set the stage for further studies of sildenafil’s immediate
and long-term effects on the heart and its ability to modify other
neurohormonal and stress stimuli, including adrenaline and
hypertension,” he adds.
