Cardiac factors affecting the success of vardenafil in erectile dysfunction.

BACKGROUND/AIM: To evaluate the predictability of vardenafil success in patients with erectile dysfunction (ED) by using cardiological tests.

MATERIALS AND METHODS

Patients diagnosed with ED who did not benefit from lifestyle changes (n = 68) were evaluated with an abridged 5-item version of the International Index of Erectile Function (IIEF-5). The pretreatment and posttreatment IIEF-5 scores were compared with pretreatment data obtained from cardiological examinations.

RESULTS

When pretreatment scores were compared with test parameters, mitral flow E/A ratio and tissue Doppler imaging (TDI) E'/ A', exercise test duration, exercise capacity in MET, and percentage of maximum heart rate were found to be statistically significant. Furthermore, there was a significant negative correlation between mitral flow E/A ratio, TDI E'/A', exercise test duration, exercise capacity in MET, and the difference in post- and pretreatment IIEF-5 scores.

CONCLUSION

As a diastolic function indicator, TDI E'/A' positively correlates with pretreatment IIEF-5 scores and negatively correlates with the beneficial effect of vardenafil treatment. As a result, the cardiological status of the patient correlates with individual IIEF-5 scores, and it seems to be useful in predicting vardenafil success.
