Viagra – Miracle Drug for Heart Disease – Sidenafil Citrate Can Be Used To Treat Heart Failure and Enlargement

Viagra – Miracle Drug for Heart Disease – Sidenafil Citrate Can Be Used To Treat Heart Failure and Enlargement

Viagra

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.
